CHRYSIPPUS
STOICISM
Born at Soli in
Cilicia Chrysippus studied under Cleanthes at Athens, succeeding him in 232 as
the third head of the Stoic school founded by Zeno of Citium (c. 336 c.
265). He is important for his
development and systematization of Zeno's doctrines; and he was called the
'Column of the Stoa' ('stoa' means 'porch') by his contemporaries because of
his impartiality and reasonableness. None of his 705 'books' has survived, but some of his sayings have been
recorded by later commentators.
LOGIC AND LANGUAGE
[1] Chrysippus held the view that there are but four categories [a], namely: the substrate, the 'essential' basis, the
'accidental' basis, and the 'relative accidental' basis. He also developed a logic of propositions [b] (as contrasted with the logic of terms of
Aristotle). Propositions are simple or
non-simple. The former are true by virtue of facts (their truth conditions);
the truth values of the latter depend on the truths of the simples out of which
they are constructed. He made full use
of dialectic techniques [c].
KNOWLEDGE
[2] According
to Chrysippus, all
knowledge is grounded in the senses. When we perceive individual material objects and form impressions
material traces are left in the soul. Experience arises out of complexes of such traces. In addition to our knowledge of individual
things we have knowledge
of general ideas [a]. These too are formed by us from out internal
traces. But Chrysippus held also that we have some general ideas prior to experience in the sense that we
have a natural disposition to produce them [b]. It is our immediate 'apprehensive' perceptions which give us the
criterion of truth, and they can be checked by deliberation, that is, by
testing them against commonly held notions similar perceptions we have
remembered. From the perceptions we had
in childhood our reason develops, by
means of which we can come to know reality as a whole.
PHILOSOPHY OF NATURE/ METAPHYSICS
[3] According to Chrysippus, reality the One Substance has
two material principles: the passive principle (to paschon) and the active principle (to poioun). The former is matter without any
qualities [a]; the latter is Reason (logos)
or God [b] conceived of not as a
personal being but as the 'ordering' factor of Nature, exhibited in 'natural
law' [b]. God is also identified with Fire [c], a finer
matter which permeates the whole universe and dwells in individuals as 'breath'
(pneuma). And It is the prime cause of everything which makes up the
world of individual bodies (there are no concrete universals for Chrysippus) [d]. The process is supposed to happen in the following
way. God as fiery vapour contains within itself 'seeds' (logoi
spermatikoi) of individual things [e]. Vapour turns into air, air becomes
water. Part of the water remains unchanged, while the rest becomes earth and air the latter
turning back to fire by a process
of rarefaction. Thus the world
ultimately returns to the primeval Fire though a universal conflagration (ekpyrosis). The whole process then
starts all over again [f]. The Stoic 'God' also manifests
itself as Fate (or Providence) in its ordering for the best everything
that happens [g]. Indeed
Chrysippus appeals to the
beauty and order of the universe as the basis for a proof of God's existence. He also said that there must be such a being to have a given man
such an idea given his limited powers of reasoning . Moreover there is a common belief in God [h].
[4] God's supposed providence raises the problem of human freedom and evil. Chrysippus says that man remains free to the extent that he can adopt a
positive attitude of acceptance towards events [a]. Evil, he argues, does not really exist when considered
from the standpoint of the universe as a whole. What seems to the
individual to be evil, for example, suffering, is but a logical complement to
its opposite, good. Thus, to be able to
experience pleasure we must also have the capacity to suffer pain. (This can even be beneficial sometimes, as
when it warns us that there is something wrong with us.) As for moral evil, the capacity for virtue is
accompanied by the capacity for vice. Chrysippus's general principle therefore is that evil is a privation [b], that is, absence of 'right order' in things.
PSYCHOLOGY
[5] Unlike the souls of animals, which posses only
imagination and impulsive desires, or of plants, which exhibit only cohesion
and movement, the human
soul is rational and is itself part of the Divine Fire. It is also
simple, devoid of parts [a]. For
Chrysippus, consistently with his Stoic materialism, there is no personal immortality though he
allows that the souls of the wise may exist after death until the conflagration
of the universe [b].
ETHICS
NATURAL LAW THEORY
[6] The aim
of the Stoic is to live "according to Nature": he regards this as
'proper' (kathekon), his duty. By this is meant that men should follow their reason, and hence the will
of 'God' in so far as man's rational nature is governed by universal law the 'active
principle' [a]. In this way man will be virtuous and hence attain happiness (eudaimonia) [b]. However, virtue is desirable as an end in itself [c]. Although the universe would seem to be a
material deterministic system, man can develop a 'right' attitude towards
it. If he acts in accordance with right
reason he can bring good out of evil by restoring order to what is
disharmonious. Intention is all-important: actions in themselves are morally neutral;
they are neither good nor bad [d]. In order to
develop the right attitude man must be at once courageous, temperate, and just,
and must possess wisdom, moral insight, and self-control. Moral training involves the elimination of feelings and desires such as
pleasure and fear, which are irrational, that is, do not conform to nature and
are therefore of no moral worth. One
thereby achieves a state of apathy ('no feeling') [e]. Chrysippus says also that there are no degrees of virtue. An individual either possesses all the
cardinal virtues or is non-virtuous. Stoicism,
however, is not entirely egoistical. Self-love is transcended in so far as man is a social being; and
Chrysippus stresses the
role of the family, society, and indeed humanity as a whole in underpinning
morality. This is the Stoic
cosmopolitanism [f].
CRITICAL SUMMARY
Chrysippus is important as
the systematizer of Stoic doctrines; and as his thought is characteristic of
that school so is it open to the difficulties raised by its philosophy. His theory of knowledge is empirical, yet he
appears to hold that some general ideas are innate albeit as
dispositions. Moreover he implies that
it is through reason that we gain insight into reality Fire, the One
Substance and into the 'natural law' which is our guide for ethics. Chrysippus's claim that moral responsibility
and hence freedom of choice are compatible with his acceptance of fate, that is
to say, the predetermination of events by a non-personal 'God', is
questionable. Likewise there might seem
to be a problem with his simultaneous commitment to both self-preservation and
cosmopolitanism, though he claims there is no incompatibility between self-love
and his love for all humanity, all men being kin and parts of the whole, the
One.
