Trang 1Plainly a non-central and precarious kind of law and legal
system, there seems no reason to doubt either its
positiv-ity, as something added by human decision to natural
morality, or its obligatoriness in some measure, in a world
where no state can plausibly claim to be a fully complete
community entitled to constitute the ultimate and
uncon-ditional horizon of a just person’s allegiance
Developments in international law in recent decades
have responded to a set of interrelated questions: Has an
individual person, or a non-state group, the right to move
international organs, as a subject of international law with
substantive and procedural rights derived from
inter-national law? Has an organization such as the United
Nations an international personality comparable to that of
a state, and are its rights in international law limited to
those conceded by the states party to its establishment?
Can the same be said of a non-governmental organization
such as the International Red Cross? If ‘persons’ other than
states can be subjects of international law rights, can they
also be creators of international law rules, as states can?
When can individuals, including rulers of states, be tried
by internationally authorized tribunals for offences
against international law? These questions, like the
tenta-tive affirmatenta-tive answers being given to them, arise from a
widespread understanding that new interdependencies,
economic, environmental, and cultural, are bringing into
being a world-wide human community which might in
principle become a fully complete community
govern-mentally equipped to supervise, coercively, the doing of
justice everywhere, but that no governmental authority
can yet be envisaged such as could be relied upon to act
with an effective justice sufficient to merit a general
trans-fer or subordination of state jurisdiction to it This last
proposition, reasonable though it doubtless is, has the
practical implication that international law will remain for
the foreseeable future a system largely bereft of sanctions
and, for that and other reasons, one that is peculiarly open
to violation and to change by fait accompli, not least by
states prominent in shaping and appealing to its rules,

Law and its Place in Jurisprudence’, in his Collected Works,

international relations, the philosophy of The set of
doctrines, ideas, justifications, and excuses that guides the
study and, perhaps, the practice of sovereign states in their
dealings with one another Two broadly opposed
pos-itions have been articulated, the first mostly by students of
politics (and also by politicians), the second mostly by
stu-dents of law (and by lawyers) Only in very recent years
has either one attracted much philosophical attention
The first position is commonly called ‘realist’ because
its advocates claim to see states as they really are (in the
tradition of Thucydides and Machiavelli) On this view,
sovereignty is taken as a kind of exemption from the moral
restraints that apply to individual men and women The rulers of states are driven by the ‘necessities’ of inter-national anarchy, standardly conceived as a Hobbesian
*state of nature, to defend the interests of their own people without regard to the rights of anyone else Thus the Greek generals in Thucydides’ Melian dialogue: ‘they that have odds of power exact as much as they can, and the weak yield to such conditions as they can get.’ Strategic and security studies are the political expression of this real-ist view
The second position is best called ‘legalist’ because it views international society, on analogy with domestic society, as a rule-governed world In the absence of a global authority that might serve as the source of the required rules, they are derived instead from the tacit or explicit consent of existing states—hence from customs, treaties, and conventions—or from some version of *nat-ural law *Just war theory is the first moral offspring of this legalist view, though many of its protagonists believe that what the domestic analogy requires is that war should be conceptually, as well as practically, repressed Unjust wars must be understood as criminal acts, and just wars simply
as police actions, aimed at law enforcement
What is at issue between realists and legalists, above all,
is the responsibility of rulers The realist view is only puta-tively amoral; its central claim is that rulers are morally bound to their subjects or fellow citizens and must be per-mitted to do, or be excused for doing, whatever they have
to do in order to guarantee the physical security and advance the well-being of those people The legalist view
is that nothing can be done for those people that they could not, as individuals, do for themselves Since they could not kill innocent people to save their own lives, innocent people cannot be killed on their behalf As this example suggests, arguments about responsibility have focused mostly on the conduct of war, with realists
insisting that inter arma silent leges and legalists refusing
to be silent even then But the disagreement extends also to questions of diplomacy and commerce Here too rulers of states commonly act as if ordinary moral stand-ards were relaxed or lifted entirely in their case: gentlemen
do not open each other’s mail, but statesmen authorize (and pay for) espionage and think themselves morally justified
The same issue also arises in discussions of distributive
*justice, which is commonly taken to deal with domestic, but not with international, transactions Of course, trade across borders is governed by the same prohibitions (against fraud, say) as trade within borders *Markets are
international; the old jus gentium was first of all market
law Governments, however, are not international, and whatever obligations government officials have to pro-mote justice—to redistribute resources, establish a wel-fare ‘floor’, ban discriminatory practices, and so on—are owed to their fellow citizens and not to foreigners But this view, standard for a very long time, has come increasingly under criticism by writers seeking some way of addressing the radical *inequalities of international society Perhaps
440 international law
Trang 2foreign aid is as obligatory as domestic welfare Perhaps
the *difference principle should be applied globally
Legalists are likely to be more sympathetic than realists to
such proposals, but even for them these are extensions of
law and morality beyond their current reach
It might be said that international distributive justice
would not require the reform of international relations so
much as its abolition—in favour of a new global
domesti-city The society of sovereign states would be replaced by
a new political entity, encompassing all the men and
women in the world and treating them with equal respect
and concern, as rights-possessing individuals But it is also
possible to imagine states of the world that fall between
international anarchy and global rule Organizations
like the United Nations, the International Monetary Fund,
and the World Trade Organization have something less
than governmental power, but they could still act, if the
leading states in the global economy wanted them to do
so, in the interests of international distributive justice

internet, philosophy on the.The Internet is awash with
philosophy Type ‘philosophy’ into an Internet search
engine, and it returns millions of entries; and
EpistemeLinks.com, the leading portal website for
philoso-phy, currently features some 13,000 categorized links to
philosophy resources on the Internet Inevitably, with this
quantity of material available, much of it is not of
profes-sional standard In part, this is because the Internet
facili-tates publication without editorial control or peer review
(which itself leads to difficult questions about the
reliabil-ity of information found on the Internet) Nevertheless,
professional philosophers and philosophy publishers are
increasingly making use of the opportunities presented by
the Internet
Most significantly, the worldwide web is beginning to
change the face of philosophy publishing Partly, it is
doing so because it offers a number of advantages over
trad-itional, non-electronic publishing (1) A single web
publi-cation has a potential audience of millions of people, many
of whom, in the case of philosophy, would not
other-wise have ready access to such material (2) The web is a
dynamic medium, allowing for published material to
be updated frequently For example, online reference
works, such as the Stanford Encyclopedia of Philosophy
(http://plato.stanford.edu), are kept up to date in a way that
their paper-based counterparts cannot be (3) By utilizing
embedded hypertext links, web publications allow for
sophisticated cross-referencing and facilitate non-linear
research strategies (4) The worldwide web makes it
relatively easy for individuals to embark on their own publishing ventures, something which philosophers such
as David Chalmers (at Arizona/ANU), Peter Suber (Earlham), Ted Honderich (UCL), and Stephen Clark (Liverpool) have exploited to excellent effect (5) It is rela-tively inexpensive to publish on the worldwide web There-fore, the option of an exclusively online journal or collection
is an attractive one for publishers Good examples of
these are The Philosophers’ Imprint (www.philosophersim-print.org), an online journal with an editorial board the
equal of any trad-itional philosophy journal, and the
Marxists Internet Archive (www.marxists.org), a digital library
of works by authors sympathetic to Marxism

and mailing lists such as Philos-L (www.liv.ac.uk/Philoso-phy/philos.html) mean that philosophers around the globe
interpretation.Theoretical or narrative account of facts, texts, persons, or events that renders the subject-matter intelligible As a genuinely philosophical problem, inter-pretation became recognized first as a specific feature of the human sciences Historical interpretation based on lived experience, understanding, and ordinary language is contrasted with scientific explanation based on alien con-struction, observation, and theoretical concepts In exist-ential and hermeneutic philosophy, interpretation becomes the most essential moment of human life: The human being is characterized by having an understanding
of itself, the world, and others This understanding, to be sure, does not consist—as in classical ontology or episte-mology—in universal features of universe or mind, but in subjective–relative and historically situated interpret-ations of the social *life-world Recent trends like *post-modernism or *neo-pragmatism have emphasized the universality of interpretation, arguing that even natural sciences are nothing but interpretations h.h.k

intersubjective.This term refers to the status of being somehow accessible to at least two (usually all, in principle) minds or ‘subjectivities’ It thus implies that there is some sort of communication between those minds; which in turn implies that each communicating mind is aware not only of the existence of the other but also of its intention to convey information to the other The idea, for theorists, is that if subjective processes can be
brought into agreement, then perhaps that is as good as the (unattainable?) status of being objective—completely
inde-pendent of subjectivity The question facing such theorists
is whether intersubjectivity is definable without pre-supposing an objective environment in which communi-cation takes place (the ‘wiring’ from Subject A to Subject B) At a less fundamental level, however, the need for

introspection. The nature of introspection and
some-times even its existence are a subject of controversy, and
so it is difficult to provide a neutral account of it It is not
just the awareness that accompanies some mental states
It is rather a person’s internal way of ascertaining what
mental state he or she is currently in
Sometimes introspection is taken to be a type of
per-ception and there is talk of a ‘mental eye’, or, if minds are
thought to be material, brain-scanning Others deny any
similarity with sense-perception and view such talk as
mis-leading They think it is acceptable to talk of introspection
as perception only if a very minimal understanding of
perception is brought to bear, in which case it is
unin-formative Another alternative is to take introspection to
be a form of recollection, or retrospection, in which case
we would have to characterize it as a person’s internal way
of ascertaining his or her mental states just past The
motiv-ation for this approach is that it is thought implausible for
one to have a thought simultaneously with having
another thought the content of which is the first thought
Much philosophical discussion has centred around the
status of the beliefs we obtain through introspection ‘Are
they justified?’ and ‘How likely are they to be false?’ are

intuition.Originally an alleged direct relation, analogous
to visual seeing, between the mind and something
abstract and so not accessible to the senses What are
intuited (which can be derivatively called ‘intuitions’) may
be abstract objects, like numbers or properties, or certain
truths regarded as not accessible to investigation through
the senses or calculation; the mere short-circuiting of such
processes in ‘bank manager’s intuition’ would not count
as intuition for philosophy Kant talks of our intuiting
space and time, in a way which is direct and entirely free
from any mediation by the intellect—but this must be
dis-tinguished from an alleged pure reception of ‘raw data’
from the senses; the intuiting is presupposed by, and so
cannot depend upon, sensory experience
Intuitions or alleged intuitions have been important in
logic, metaphysics, and ethics, as well as in epistemology
Recently, however, the term ‘intuition’ has been used for
pre-philosophical thoughts or feelings, e.g on morality,
which emerge in thought experiments and are then used

intuitionism, ethical.Ethical intuitionism is mainly asso-ciated with British philosophers; it is sometimes called British intuitionism But the term ‘intuitionist’ is used for more than one position In one sense, intuitionism is the view that basic moral truths are known by intuition—that
is, directly, rather than by inference In this sense, Sidgwick was an intuitionist More recently, intuitionism has been taken to be a form of pluralism, pluralism in the theory of the right Monists in the theory of the right say that there is only one way in which an action can get to be right Kant was a monist, and so was G E Moore, who held at one time that for an action to be right is for it to have the best consequences Against Moore, Ross argued that actions can be made right in any of a number of ways

intuitionism, mathematical A school founded by L E J Brouwer (1881–1966) which construes mathematics as mental constructions, opposing the view that mathemat-ical reality is independent of our thought (Intuitionism is thus a species of *constructivism about mathematics.) The intuitionist criticizes classical mathematics for its unrestricted use of the law of excluded middle, the claim
that ‘A or not-A’ is always true Classically, one may prove
A by refuting not-A, or by showing that A follows both from B and from not-B But for the intuitionist, if a
state-ment is neither provable nor refutable, we cannot assume that either it or its negation is true: there is no mathemat-ical reality, independent of our thought, to settle the truth-value of all mathematical statements See *intuitionist logic for the framework in terms of which intuitionists investigate how much of mathematics survives their cri-tique The applicability of intuitionist thought outside mathematics has been explored by Dummett d.e

intuitionist logic A logic in which truth is equated with provability, or warranted assertibility, or something of the kind Let us use ‘’ to abbreviate ‘We have grounds for asserting’ or ‘We have a proof ’ or ‘We have a method which, if applied, would yield a proof ’, and so on Then the intuitionist connectives answering to ‘and’, ‘or’, ‘if ’, and ‘not’, are explained thus:
(P & Q) if and only if P andQ.
(P∨ Q) if and only if P orQ.
(P→ Q) if and only if (IfP thenQ).
¬P if and only if notP.
In words, the explanation of ‘→’ would often be given
thus: ‘We have grounds for asserting that P→Q if and
only if we have a method of transforming any grounds for
asserting that P into grounds for asserting that Q’ And the
explanation of ‘¬’ would be: ‘We have grounds for
assert-ing that ¬P if and only if we have grounds for assertassert-ing that
we could never have grounds for asserting that P’ (An equivalent account defines ‘¬P’ as abbreviating ‘P→ ⊥’,
442 intersubjective
Trang 4where ‘→’ is understood as above and ‘⊥’ represents an
arbitrary contradiction.) As for the quantifiers, where D is
the domain of quantification, the explanation is
∃xFx if and only if for some object a,(a is in
D) and Fa.
∀xFx if and only if (for every object a, if (a
is in D) then Fa).
The logic that results from these explanations differs
from classical logic primarily where negation is
con-cerned Notoriously, it lacks the law of *excluded middle
‘P∨¬P’, for on the intuitionist account we should have
grounds for asserting that P∨¬P only if we have grounds
either for asserting that P or for asserting that we could
never have grounds for asserting that P But of course it
may be that we do not have grounds for either Similarly,
this logic lacks the law ‘¬ ¬P→P’, and many other
clas-sical laws for negation This has some unexpected
conse-quences For example, none of the connectives and
quantifiers listed above can be defined in terms of any
combination of the others
The simplest way of formulating intuitionist logic is in
a style suitable for *natural deduction, with one
introduc-tion rule and one eliminaintroduc-tion rule for each sign The rules
are just the same as the classical rules in all cases except for
negation, where the introduction rule is reductio ad
absurdum and the elimination rule is ex falso quodlibet.
There are several ways of giving a formal semantics for
this logic, the most popular being that based on ‘Kripke
trees’, but this topic is too complex to be explained here
There are also several ways of ‘translating’ some or all
of intuitionist logic into classical logic The most
inter-esting one, because it seems to be most in accordance with
the intended meaning of the intuitionist connectives and
quantifiers, is this In the explanations given earlier,
assume that the English expressions used on the right
are the classical connectives and quantifiers Then where
φ is any formula of intuitionist logic, the formula φ
will translate, via these explanations, into a formula φ*
containing only classical connectives and quantifiers,
interspersed with occurrences of It turns out that φ is
valid intuitionistically if and only if φ* is valid in the modal
logic S4
Intuitionist arithmetic is obtained by adding to this
logic the same axioms as for classical arithmetic The two
arithmetics differ only on formulae involving quantifiers

inverted spectrum.That two people outwardly indistin-guishable in their colour discriminating may nevertheless systematically differ in their colour experiences was a
pos-sibility raised by Locke (Essay, bk ii, ch xxxii) Under the title ‘spectrum inversion’ it has entered modern debate via objections to *behaviourist accounts of the mind that at least some conscious mental states have no clear relations
to behaviour Similarly, the causal relations that *func-tionalists appeal to in accounting for colour discrimin-ation are dogged by the possibility of subjective differences which, being systematic, escape the functional net Some functionalists argue that spectrum inversion is a meta-physical possibility, but scarcely credible, while, being epiphenomenalists, they may not care anyway Those who take colour experiences to be states of the brain rely
on the possibility of inversion being discounted explana-torily by future neurobiological advances It is neverthe-less difficult to say what precise discoveries would enable science to explain what Locke himself could only describe
as God ‘annexing’ ideas in our minds to certain objects

Irish philosophy There has been only one period of
con-tinuous, creative philosophy in Ireland—from the 1690s
to the 1750s Before that the only prominent figure is John
Scotus Eriugena, whose work has some points of contact
with that in the eighteenth century, particularly in its
ten-dency towards *pantheism, negative theology, *idealism,
and heterodoxy; although Irish philosophy has been
traced back to the so-called Irish Augustine,
c.sixth century After the 1750s, the most noteworthy
philosophical activity—at least until now—has been
derivative and scholarly, either within Catholic
scholasti-cism, or in elucidating and editing the work of Berkeley
(A A Luce), Kant (T K Abbott), and Hegel (H S
Macran)
The outstanding figure in Ireland’s one creative period was George Berkeley, whose principal writings indicate the main concerns of Irish philosophy, i.e epistemology, theory of perception and language, and philosophy of reli-gion Also important, however, is the contribution in aes-thetics by Francis Hutcheson—who was born and died in Ireland and produced most of his important books while teaching in Dublin in the 1720s—and Edmund Burke,
whose chief philosophical work, Philosophical Enquiry into the Ideas of the Beautiful and the Sublime (1757), was largely
written while he was a student at Trinity College in the late 1740s While Berkeley, Hutcheson, and Burke are probably the best-known names, there were other able philosophers—among them, John Toland, William Molyneux, William King, Peter Browne, Robert Clayton, and Edward Synge There were also popular writers, most notably Jonathan Swift, some of whose writings reflect key theories and arguments in Irish philosophy
The seminal work is Toland’s Christianity not Mysterious
(1696), which, drawing chiefly on Locke’s theories of meaning and essence, argues that Christianity either asserts meaningless doctrines—‘Blictri’—or is a non-mysterious religion Toland’s rationalist challenge was answered by Browne, then a Fellow of Trinity College,
first in his Letter (1697) and, more weightily, in his Proced-ure, Extents and Limits of the Human Understanding (1728),
which argues for the old negative theology by developing
a radical sensationalist account of mind Browne, like
Toland, was influenced by Locke, whose Essay is the most
important external influence on Irish philosophy There are two principal tendencies in Irish philoso-phy—the and right-wing Lockeans Toland is a left-winger, drawing on Locke’s rationalism and enlightened attitude to religion Browne is in the right-wing, which uses Locke’s empiricism and the sceptical and quietistic
trends in the Essay Yet neither those on the left nor those
on the right were slavish adherents of Locke; instead, they were often his most astute critics, boldly drawing out con-clusions from his work which he was either unable or unwilling to accept Molyneux comes closest to being a follower; yet he is more a collaborator than a disciple
Indeed, the final form of the Essay owes more to him than
anyone (apart from Locke), as their correspondence, pub-lished in 1708, clearly shows Another creative response to Toland from the right was by Archbishop King, whose
Sermon on Predestination (1709) defends religious mystery
by applying *representationalism and the *primary–sec-ondary quality distinction to theology King is also
remembered for his influential De Origine Mali (1702),
which is appreciatively discussed by Leibniz in his
Théodicée.
Toland’s challenge also gave rise to Berkeley’s preco-cious emotive theory of meaning, which Berkeley uses in
Alciphron (1732), dialogue vii, to explain religious mystery.
Yet Berkeley was not a clear adherent of the right wing
Thus in Alciphron, dialogue iv, he forcefully attacks the
Browne–King theological position and in ways remark-ably similar to those he had earlier used against matter
444 inwardness
Trang 6Browne counter-attacked in his Divine Analogy (1733),
whose scornful and incredulous comments on Berkeley’s
emotive theory of mystery shows the revolutionary
char-acter of the theory, a theory which Burke uses in his
Philo-sophical Enquiry along with sensationalism, which he
probably derived from Browne Another topic which
shows the inner unity and interest of Irish philosophy is
the *Molyneux problem Not only was it devised by an
Irishman, but some of the most interesting responses to it
were made by Irishmen—Berkeley, Hutcheson, Synge, as
well as (less directly) Swift and Burke d.ber

irony, Romantic Notion of irony as an attitude or ethos
that calls everything into doubt, from utterer’s intentions
to our knowledge of the world as given (supposedly)
through sensory acquaintance or the concepts and
cat-egories of reason Such ‘infinitized’ irony—as distinct
from its ‘stable’ or unproblematic varieties—aroused
great interest among poet-philosophers in the
early-to-mid-nineteenth century, notably Novalis, Hölderlin, and
Friedrich Schlegel These thinkers pursued the various
problems bequeathed (as they saw it) by Kant’s critical
philosophy, e.g the *antinomies of subject and object, of
*freedom and *determinism, and of thought as a
perpet-ual striving for truth in the face of human finitude Hence
their fascination with the giddying depths of
uncer-tainty—the interpretative mise-en-abîme—opened up by
reflection on this topic Such thinking was attacked by

in the solution of a computational problem What he would insist upon is that principles such as those of prob-able and demonstrative reasoning that are used in the mental activities mentioned are, though appropriate and effective in their own spheres, inapplicable to issues of superior importance like the spiritual self-realization of the ego, the ultimate destiny of humankind, and the tran-scendent ground of the existence of the world Within the domain to which these issues belong, he would contend, knowledge can only be attained through some non-logical and non-empirical modes of direct cognition such as are encountered (in purest form) in mystical intuition or in faith induced by some transcendental source
Faith and *intuition, then, on this reckoning, are and ought to be recognized as the superiors of reason in mat-ters that matter Although the concept of reason has been variously interpreted, it has an uncontroversial core of ref-erence which includes deductive and inductive infref-erence,
to which allusion has already been made, and the logical and semantical analysis of concepts and statements based
on clearly ascertainable rules Given that these procedures
of thought are supposed to be incapacitated in the areas of cognition reserved by the irrationalist, it is apparent that any inquiries by the unconverted into the intelligibility, not to talk of the validity, of the deliverances of faith and intuition are irremediably handicapped And this is, pos-sibly, the most striking thing about irrationalism: it is apt
to become a constraint on dialogue
It is a remarkable fact that some of the greatest thinkers
in the history of Western philosophy have had some irrationalist leanings, however peripheral in some cases Thus so ingenious a dialectician as Plato seems to have credited knowledge of the profoundest truths exclusively
to some superior mode of unmediated cognition, exempt from all possibility of error and therefore of debate; and
St Thomas Aquinas, for all his demonstrated powers of reasoning, conceded some truths to the sole competence
of faith Even Kant, giant of the Enlightenment, confessedly
found it necessary to ‘deny knowledge in order to make room for faith’.
irrationalism 445
Trang 7But, of course, reason has not lacked its philosophical
celebrants It is not for nothing, for example, that the
seventeenth and eighteenth centuries in European
history have been called the Age of Reason The rational
foundations laid in the teachings of
seventeenth-century thinkers like Bacon, Locke, Leibniz, Spinoza,
reached their denouement in the optimistic rationalism
(using this word in the broad sense) of the stalwarts of
eighteenth-century Enlightenment such as, to mention
only a few, Bentham and Godwin in England and Voltaire,
Diderot, and Montesquieu in France Their shared
con-viction, which may not at times have been without a
touch of hyperbole, was that it was entirely possible to
improve the human condition out of all recognition
through the expansion of the role of reason in human
affairs
It was in reaction to this enthusiastic trust in reason that
Romanticism emerged in art, literature, and philosophy in
the nineteenth century as perhaps the most
self-consciously irrationalist movement in Western thought
In contemporary culture there are not a few currents of
irrationalism—witness, for instance, the ‘new age’
move-ment and the even grosser tendencies to demonism in
sectarian life—but in serious philosophy familiar
animad-versions against Reason, when duly analysed, are
fre-quently revealed to be in reality more against certain
conceits about reason than against reason itself k.w

‘is’ and ‘ought’ Moral philosophy has to give an account
of how, if at all, we can legitimately move from is to ought,
from describing how things do in fact stand, to expressing
an urgent concern either that they be changed or that they
be respected, preserved as they are If the is–ought gap is
over-dramatized, value is detached altogether from the
world and becomes a function of sheer decision But
moral deliberation does not and cannot work in a factual
vacuum To underplay the gap is to suggest, no less implausibly, that an ought can be simply read off from
an is.
A satisfactory account must start from the idea that
ought and is interpenetrate We may grasp a situation as
demanding action: conversely, reflection on values and obligations powerfully affects our understanding of human nature and its potentialities

Islamic aesthetics.Much Islamic aesthetics, like Islamic philosophy as a whole, is thoroughly Neoplatonic This replaced the earlier theories of thinkers like al-Kindı¯, for whom beauty is taken to be derived from perfection, and since God is the most perfect being in the universe, he is also the most beautiful He is constantly aware of his beauty, while we are only occasionally able to come close
to experiencing it, since it is an essential feature of the deity, but its perception is merely an accidental human attribute This version of Pythagoreanism was replaced by the argument that we operate on the level of imagination,
so our ideas of beauty are limited to what we can experi-ence and abstract from those experiexperi-ences On the other hand, we can use our material ideas and experiences to construct more abstract and perfect concepts of beauty, and so come closer to the range of completely pure beauty which exists far from the material world
The area of aesthetics which came in for much discus-sion was poetry, and the ways in which poetry works logic-ally Many of the Islamic philosophers such as al-Fa¯ra¯bı¯, Avicenna, and Ibn Rushd were convinced that poetry fol-lows a syllogistic pattern of proof, albeit with far weaker premisses than most such reasoning processes, and with the conclusion that the audience should be moved to action or emotion Imagination is again crucial here, blending our ability to be both spiritual and material Our material ideas reflect our experiences, yet they can be made more abstract, and thereby extend those experi-ences in novel and exciting ways.Were we to be entirely rational, we would not need imagination, and could be spoken to entirely in terms of what we regard as logical; but since we are emotional creatures, we require to be addressed at least partially through our emotions, and this
is where poetry and other art-forms come in They appeal
to us both intellectually and emotionally, and persuade
us that we should adopt a certain attitude or share a

Islamic ethics.Ethics in Islamic philosophy is a surpris-ingly uncontroversial area, since most thinkers agreed
on the general principles of ethics There was an early
446 irrationalism
Trang 8theological dispute as to how objective the principles of
ethics are, but this did not really become part of the debate
in philosophy The latter took off when the views of Plato
and Aristotle became familiar to Islamic philosophers,
especially the notion of the just society in the Republic of
Plato and virtue as a mean in Aristotle’s Nicomachean
Ethics One of the issues which the Islamic thinkers had to
address was how to discuss happiness in such a way that it
would be available to all who were prepared to behave
well, as opposed to just those who were intelligent The
Aristotelian debate about how far the moral and social life
is important, as compared to the life of the mind, was of
particular interest, since the idea that salvation was
restricted to those who are intellectually gifted is hardly
compatible with Islam Al-Fa¯ra¯bı¯ and Ibn Sı¯na¯ (Avicenna)
imply that the masses’ route to salvation is through
religion and morality, while the philosophers’ route is
through philosophy
Ibn Miskawayh (d 1030) and Nas.ı¯r al-Dı¯n al-T.u¯sı¯
(d 1274) produced very elaborate discussions of ethics,
and the philosophical psychology which accompanies
them displays considerable acuity God is taken to be the
epitome of the religious law which incorporates both
spiritual and physical goods We should obey not only
God, but also his representatives on earth, and all those
who are superior to us morally The view of human beings
being the representatives of God is particularly attractive
to Shı¯‘ite thinkers, who can relate the imam or spiritual
leader with the deity in this way
A particular interesting debate arose in the work of
al-Ghaza¯lı¯ (d 1111) and is his response to an argument
produced by Ibn Miskawayh The latter argues that the
religious and moral law is based on what is in our interest,
and that we can see what the point of the law is by asking
what its point is Al-Ghaza¯lı¯ replies that the point of the
moral and religious law is that it has no point; it is entirely
arbitrary and rests on nothing but the will of God Some
people may follow the principles of morality out of some
confused idea that they are the right principles, but unless
they follow those principles because they believe they are
commanded by God to do so, their action is without
value Here al-Ghaza¯lı¯ is using the ideas of an earlier
theo-logical debate between the Mu‘tazila and the Ash‘ariyya
on the basis of morality For the former, morality can be
derived from reason, and that is why God establishes it,
since he acts in accordance with reason The Ash‘arites
argued, by contrast, that morality means nothing more
than what God demands of us, and it has no basis apart
from that
It was the Ash‘arite view that prevailed in Islamic
philosophy The objectivist account of ethics of the
Mu‘tazilites was held to suffer from a number of
prob-lems It places huge reliance on the ability of human
rea-son to determine our moral duty It also implies that
religion plays no significant role in determining morality,
and that religious law is not an essential part of that
moral-ity Yet the Qur’a¯n itself points frequently to the
signifi-cance of guidance for human beings, and although reason
is clearly important in assessing what form of guidance is valid, it cannot replace the authority of God as revealed to his representatives on earth This notion of human beings being divine representatives is often taken to be important morally, and has implications for how we can behave and what our relationships should be with each other and with our environment in general It is worth pointing out that the starting-point for working out what our duties as God’s representatives on earth are is Scripture, and with-out divine guidance we would have no idea how to

Islamic philosophy Originally based on Arabic transla-tions of Greek texts, developed as a syncretic yet system-atic body of thought in the Islamic world, from Andalusia
to India, from the ninth century to the present Most works were originally written in Arabic, many in Persian Though marked during its formative period by Mu‘tazila theologians, who were influenced by issues of revelation and reason in Christian theology (e.g Origen, John of Damascus), Islamic philosophy does not constitute a reli-gion; nor was it the ‘handmaiden of theology’ Most prac-titioners were Muslims of various cultural, social, and linguistic backgrounds; some were notable members of other religions
The Formative Period: The Late Eighth to Mid-Ninth Century.
Philosophical activity at this time centred in Baghdad’s new Academy (‘House of Wisdom’) Supported by the caliphs, notably al-Ma’mu¯n (reigned 813–33), the school was known for its academic tolerance and freedom of sci-entific inquiry Learned representatives of all subject nations participated in the state-endowed centres where a universal world-view was sought to sustain the Empire Some extremist groups questioned the caliphs’ authority, introducing critical political issues (later addressed by theo-logians such as Ba¯qilla¯nı¯ and Baghda¯dı¯) and theoretical problems (later picked up by Fa¯ra¯bı¯ and Avicenna) Others, drawing upon older traditions (materialist, Manichaean, Jewish, Christian, Zoroastrian, Arabian, and Indian), challenged Islamic philosophy’s fundamental doctrine of revealed truths by identifying its supposed contradictions and inconsistencies The Mu‘tazila thus established a set of doctrines regarding anthropo-morphism and God’s knowledge, creation, prophecy, human free will, and immortality Greek thought became the most attractive tool for the construction of a defined Islamic theology, providing a rational defence for revealed teachings
One major thinker of this period was al-Kindı¯, who
was interested in philosophical investigation per se.
Although upholding the validity of revealed truth, he also proposed its recovery by demonstration He did not attempt a systematic ‘harmonization’ of prophecy with philosophy, however, one of the primary goals of the
Islamic philosophy 447
Trang 9following period His main contribution was identifying
Greek texts and refining their Arabic translations, some of
which he commissioned They include extensive
para-phrases of Pre-Socratic authors; Plato’s Laws, Timaeus, and
Republic, plus paraphrases of Phaedo, and other Platonic
texts; most of the Aristotelian corpus except the Politics;
selected Neoplatonic texts, some incorrectly identified
(notably parts of Plotinus’ Enneadsiv–vi, thought to be
‘Aristotle’s theology’), as well as works by Porphyry
(espe-cially the Isagoge) and Proclus; plus many other texts and
fragments, including elements of Stoic logic and physics
associated with the late antiquity schools of Alexandria
and Athens; and significant Aristotelian commentaries,
notably those of Alexander of Aphrodisias, along with
their Neoplatonist interpretations
Al-Kindı¯’s syncretic approach is based on Neoplatonist
theories of emanation and the concept of the One,
Aris-totelian metaphysics of causality and intellectual
know-ledge, and Platonic doctrines of the soul and dialectic
method Aristotelian logic was used to investigate
Hel-lenic-defined problems as well as the ‘new’ set of issues
fundamental to Islamic revelation Al-Kindı¯ argued for
creation ex nihilo as a type of emanation, but not natural
causation where the First Being is created simply by God’s
eternal will He also argued for immortality of the
individ-ual soul as the rational explanation for resurrection His
arguments as well as some of their corollaries were later
rejected or revised, but his writings, especially in
theoreti-cal philosophy, represent the foundations of Islamic
philosophy
The Creative Period: The Ninth to the Eleventh Century The
rise of anti-rationalist sentiments proclaimed by
al-‘Ash‘arı¯ (912), along with political events and populist
movements, curtailed Islam’s spirit of scientific discovery,
while radical advancements were taking place in areas
such as computational mathematics and astronomy Two
notable philosophers of this period, al-Fa¯ra¯bı¯ and
Avi-cenna, met the challenge by harmonizing reason with
revelation, introducing innovations, and refining
philoso-phical technique and analysis There are three seminal
innovations of this period:
1 Al-Fa¯ra¯bı¯’s commentaries on Aristotelian texts of
the Organon define a standard Arabic logical terminology
and improve formal techniques His independent
techni-cal works, such as Utterances Employed in Logic and the Book
of Letters, describe a new linguistic structure and examine
‘how many ways a thing is said’
2 Al-Fa¯ra¯bı¯ creates the first works on Islamic political
philosophy within the context of Islamic religion His
Attainment of Happiness and the Political Regime are novel in
their technical discussions of prophecy and creation, and
the roles of the lawgiver and divine law in the city
Redefined metaphysically as the ‘science of politics’, these
philosophical domains are promoted as the means for
attaining happiness and the establishment of just rule,
stipu-lated to be the ultimate purpose of philosophy Fa¯ra¯bı¯’s
most popular work, The Ideas of the Inhabitants of the
Virtuous City, furthered the doctrine of just rule by
encour-aging philosophical discourse on prophecy and law, which affected the beliefs and actions of the entire Muslim com-munity The text describes an epistemology based on Aris-totelian theories of intellectual knowledge and active intellect wherein human prophetic knowledge is not restricted by God’s will Thus any person devoted to philosophical inquiry may gain access to unrestricted, objective knowledge, or union with the active intellect This theory of knowledge, later refined and reformulated
by Avicenna into a unified theory of prophecy, is one of the most significant components of Islamic philosophy It informs the Shı¯‘a political doctrine in the sixteenth cen-tury and its later refinements, where the ‘Virtuous City’ is invoked to describe divinely inspired just rule by the philosopher-ruler, then called ‘jurist-guardian’
3 Avicenna defines Islamic Peripatetic philosophy in the first independent, comprehensive corpus on the sub-ject Most of his texts were later translated into Latin, and their arguments used by scholastic authors from Bacon to Ockham Avicenna is distinguished from previous thinkers by his recomposition of the entire range of philo-sophical subjects, adding fresh arguments and refining earlier ones He incorporates political theory into a recon-structed metaphysics, describing prophecy as a general-ized theory of intellectual knowledge capable of describing mystical experience His ontological distinc-tion between contingent and necessary being became accepted doctrine He is the first thinker to state the psy-chological theory that an individual suspended with no spatial or temporal referents will necessarily affirm his soul as an act of self-identification and that the soul’s active imagination is responsible for the feeling of pain or pleas-ure after separation from the body These novel concepts were considered by Sohravardı¯, the founder of Illumin-ationist philosophy, as essential components in the chain of being Avicenna’s theories of prophetic knowledge, based
on notions of ‘holy intellect’ as well as Koranic exegesis, were accepted by religious scholars, especially in the post-medieval period Avicenna’s students, including Gorga¯nı¯ and Bahmanya¯r, become identified as Peripatetics, consti-tuting Islam’s first ‘school’ of philosophy, as such
The Period of Reconstruction and Reaction: The Twelfth to the Fifteenth Century Several political and intellectual currents
run through this period, which is also marked by the rise of al-Ghaza¯lı¯’s ‘Ash‘arite theology After the Abba¯sid caliphate was overthrown by Mongol conquests (thir-teenth century), Islamic philosophy subsisted in multiple intellectual centres, which had also spread to the West In the fourteenth century, fundamentalist traditionalism was promulgated through the eclectic polemics of Ibn Taymiyya, who called for believers to rid Islam of all forms of innovation
Two main types of philosophical writing emerged in Andalusian centres such as Cordoba and Seville in the twelfth century: the philosophical writings of Ibn Ba¯jja (d 1138), Ibn T.ufayl (d 1185), and others extend al-Fa¯ra¯bı¯’s
448 Islamic philosophy
Trang 10political doctrine; and the Aristotelian commentaries of
Averroës, called ‘the Commentator’ in Latin texts
Ibn Ba¯jja interprets al-Fa¯ra¯bı¯’s political doctrine in a
pes-simistic light Although upholding the virtues of the ideal
city, he considers it non-existent, emphasizing the dark
aspect of actual cities in which the populace lives in the
cave (after Plato) but perceives only shadows Unlike
al-Fa¯ra¯bı¯, he considers the city incompatible with the
philosopher’s need for solitude He supports Avicenna’s
idea of experiential knowledge, or ‘enlightenment’,
through conjunction with the active intellect (Directives
and Remarks,ix, x), but considers the value of ‘prophetic’
knowledge to be individual not collective
Ibn T ufayl also extends al-Fa¯ra¯bı¯’s political doctrine in a
pessimistic direction Inspired by Avicenna’s
philosoph-ical allegories and mention of an ‘Eastern Philosophy’
with non-Peripatetic ‘wisdom’, he created an allegory in
which a wise hermit from a deserted island comes to
civi-lization with the gift of theoretical knowledge but fails to
save the multitudes (translated in English as The
Improve-ment of Reason (London, 1708) ).
In the East, the philosophy of illumination, constructed
by Sohravardı¯, represents Islamic philosophy’s most
suc-cessful response to this period’s reactionary stance
Com-mentaries by Molla¯ S.adra¯ and others extend its political
doctrine to other areas Sohravardı¯ offered a clear and
accessible system, calling for the enlightened rule of the
divinely inspired, appearing in every age, who manifest
signs indicating knowledge and power, and thus become
authorities who serve as rulers or ‘hidden’ guardians of
justice The sixteenth-century Shı¯‘a scholars readily
identified with the philosophy of illumination and used it
in the formulation of Shı¯‘ite political doctrine It remains
one of the three accepted schools of Islamic philosophy
to date
The philosophy of illumination includes many
tech-nical innovations In logic these include definition of an
independent modal operator ‘necessarily/it is necessary
that’ in defining a superiterated modal proposition as the
form to which all other propositions are reduced; the
impossibility of the ‘necessary and always true’ validity of
the universal proposition because of the necessity of
future contingency; and reduction of the figures of
syllo-gism The principal epistemological innovation was a
uni-fied theory of knowledge capable of explaining all types of
knowledge—prophetic, inspired, and sensory In a highly
innovative manner, Sohravardı¯ posits a reformulated
proposition of the sameness of knowing and being as the
foundation for a unified epistemological theory A most
general concept of ‘knowing’ is assumed, for which the
verb ‘apprehension’ (idra¯k) is used It is then stated that
any type of ‘knowing’ is that the ‘knower’ and the
‘known’, as the apprehender (mudrik) and the
appre-hended (mudrak), the sensing and the sensed, the
intel-lected and intellect, and so on, form a sameness relation
Such a relation is identity preserving one-to-one
corres-pondence among each and every member of the set of all
‘knowers’ and the set of all ‘knowns’ in any type of
‘know-ing’ New ideas in ontology and cosmology involved cosmological light essences and time-space continuum, where measured time and Euclidean space apply to the corporeal realm, and time without measure and
non-Euclidean space define a separate realm called mundus imaginalis The notion of an intermediary realm of imagin-ation, the mundus imaginalis, was a crucial development,
especially as elaborated by illuminationist commentators Shahraz‘rı¯ (thirteenth century), Ibn Kamm‘na (thirteenth century), Davva¯nı¯ (d 1501), Dashtakı¯ (d 1542), and others, whose work contributed to the origins of Islamic religious philosophy
During the second half of the twelfth century, a new genre of philosophical works by theologians emerged which continue to be taught today The most significant impetus for these were al-Ghaza¯lı¯’s demands on theolo-gians to defend the faith against rational philosophy by use
of philosophical technique and language Two texts by
Athı¯r al-Dı¯n Abharı¯ (d 1264), Guide on Philosophy and Commentary on the Isagoge, established the range of
sub-jects and language, and elucidated the forbidden aspects of philosophy These include Avicenna’s cosmic motion and Sohravardı¯’s time-space ‘will-less’ continuum theories of
the propagation of lights The Guide on Philosophy is
divided into three parts—logic, physics, and
physics—consisting of metaphysica generalis and meta-physica specialis The most popular commentary on this
work, written in 1475 by Mir Husayn Maybudi, is
custom-arily read along with the text Commentary on the Isagoge, a
primer in logic, is also read with commentaries, such as that by al-Fana¯rı¯ (d 1470), often along with glosses, super-glosses, and versifications
While numerous works of this genre continue today, most tend to lack the philosophical depth and creativity revived in the sixteenth century by Molla¯ S.adra¯ and extended by Molla¯ Hadı¯ Sabzeva¯rı¯ (d 1878) Exceptions
include the treatise Sun-Radiance (Shamsiyya) by Dabı¯ra¯n
Qazvı¯nı¯ (d 1276), presented in Nicholas Rescher’s
Temporal Modalities in Arabic Logic (Dordrecht, 1967),
which includes one of the most precise pre-modern defin-itions and comprehensive listing and discussion of simple and compound modal propositions and modalities, their contradictories, rules for their conversions, as well as an intricate analysis of validating modal syllogisms Qazvı¯nı¯’s text, together with its commentary by medieval theologian-philosopher Tafta¯za¯nı¯ (d 1389), author of
Refinements on Logic and Theology, became a textbook The Period of Revival: The Sixteenth to Early Seventeenth Cen-tury This period coincides with Safavid rule in Iran, which
established Shı¯‘ism as the state religion, primarily as a defensive measure against conquests by the Ottoman Sunnı¯ Empire A new world-view with rational but wider appeal was sought to re-establish the ruling Safavid’s legitimacy and to defend his position against the better-established theology and judicial doctrine of the Sunnı¯ Similar to the academies of the formative period, the Safavid’s well-endowed centres supported scholarship
