DIDEROT
(1713 84)
ECLECTICISM
Denis Diderot was
born in Langres, France, the son of a master cutler, and educated by the
Jesuits and at the University of Paris (1729-32). For many years, and often in poverty, he
furthered his education by private study, especially in languages and the
sciences, earning a meagre living as a translator. From 1746-72 he worked on his great Encyclopedia (with d'Alembert as
co-editor). The appearance of this work
led to much criticism and censorship by political and religious
authorities. He was also a novelist and
dramatist and the author of many satirical essays. Befriended by Catherine the Great of Russia,
he visited that country in 1773, and returned to Paris the following year.
PHILOSOPHY OF NATURE AND MAN
[1] Diderot held no fixed philosophical
position. However, in general he held
that the universe (like
his thought) is constantly in flux and is material. All things contain within themselves
opposites [a] being and non-being, growth
and decay. Motion and 'sensitivity' are intrinsic (not given
by God): he allows for the possibility that the smallest particles of matter, atoms, might possess
some primitive inner force or consciousness and perceptual capacities [b]. Moreover the development of the
world is evolutionary. Material things become more complex, leading to the
emergence of animate beings. Man's cognitive and
psychological life (sensations and association of ideas) is grounded in
physiology. The self is thus understood
ultimately in material terms [c]. The will, he says, is the final
impulse of 'desire' or 'aversion' and is thus 'determined' [see D'Alembert's Dream] [d].
KNOWLEDGE/ LANGUAGE
[2] Because the universe is constantly
changing (only the infinite totality can be regarded
as permanent), science,
Diderot says, cannot provide any ultimate knowledge
of nature. Our limited knowledge,
however, is to be obtained through the experimental method, which is rational,
but not through pure reason on its own. As for mathematics, this can of itself give us no direct insight into
reality [see Interpretation of Nature] [a]. He also warns against the using of abstractions [b], that is, symbols or linguistic signs,
without regard to any content which can tie them to the empirical world;
otherwise this can introduce obscurity into our thinking [D'Alembert's Dream].
ETHICS/ RELIGION/ POLITICAL PHILOSOPHY
[3] [See D'Alembert's Dream.] Diderot
accepted that ethics
should be grounded in the law of nature: but he located this in human nature the unity of instincts, feelings,
desires, and not in any absolute a priori moral principles of rationalist
theology [a]. (As to his own
religious beliefs, he was initially a deist but later turned atheist.) His approach tended to be pragmatic and
empirical; and he appealed
to the ideals of benevolence and humanity as guides to moral behaviour [b]. In his
later years he advocated a form of Stoicism. In his political philosophy he anticipated social contract theories [c].
Sovereignty lies with the people, to whom legislatures should be
subordinate. Critical of the power of organized religion, he
argued in favour of the separation of church and state [d].
AESTHETICS
[4] [See D'Alembert's
Dream and Encyclopedia article on
'the Beautiful'.] Diderot offers an empirical account of
art and creativity. The genuine artist
has the capacity to perceive relationships by means of association and
analogies and to translate
his emotions into works of art by means
of his imagination. Using sounds,
colours, words, gestures (depending on the kind of art he is working with) he can communicate subjective
beauty which relates to the works' inner rhythms or structures (harmony,
proportion). Beauty is objective in so far as the totality of
individual experiences of a work of art contributes to its utility in practical
life (he rejects a priori transcendent 'realities'). The sublime relates to the emotions stimulated in
the observers by a work of art [a]. Diderot also stressed the close association between
aesthetics and ethics [b].
CRITICAL SUMMARY
An obvious objection is
that Diderot's thought is in constant flux. Nevertheless, in his openness to
new ideas, his reliance on empirical methods, and general eclecticism he epitomized, perhaps more than
most, the best features of the French philosophes. His importance probably lies in his
dissemination of Enlightenment philosophy through the Encyclopedia. He may also
be seen as having anticipated Darwinism and modern theories of neural activity
as the basis of mental phenomena. However, there is dispute as to the extent to which he was a materialist
in his theory of knowledge and his
account of human nature, and whether his 'reductionist' and determinist
position is consistent with his ethics.
