The French Encyclopedists
The Encyclopedists removed from Deism the great factor of
natural religion, retaining only its critical method as applied to the history
of religion. The head of this school was Denis Diderot (d. 1784), and its great
organ of expression was the Encyclopedie.
The state censorship, however,
compelled the projectors to call to their aid a number of contributors of
conservative views and to bring their skeptical method to the task of defending
the compromise between reason and revelation.
In this spirit the main religious
topics were treated, but by a subtle infusion of the spirit of Bayle and the
expedient of cross-references from these articles to topics which might be
handled with greater freedom, Diderot succeeded in supplying the desired
corrective.
It was the circle of Holbach (d. 1789) that dared to apply the most
extreme consequences of materialism to religious questions. Helvetius (d. 1771)
prepared the way with his De l'esprit (1758), in which he expounded a
materialistic psychology and ethics.
Their moral theories, deriving though they
did from Hobbes and Hume, lost all connection with the position of Deism, which
became for them a mere armory of weapons for the destruction of all religion
with its consequences, intolerance and moral corruption. Holbach is undoubtedly
the author of the Systeme de la nature, which appeared in 1770 as the
work of Mirabaud.
The Systeme is not original in ascribing the beginnings
of religion to human hope and fear and to ignorance of the laws of nature.
Fraud, ambition, and unhealthy enthusiasm have made use of it as a means of
political and social influence and have succeeded in crystallizing its primitive
emotions into positive creeds, within which animistic tendencies have been
developed and subtilized into systems of metaphysics and theology -- the sources
of irrational intolerance.
From Holbach and his circle, and from the cognate group of the Encyclopedists, proceeded the so-called ideological school, who held the main problem of philosophy to be the analysis of the mental conceptions aroused by sensations from the material world (Condorcet, Naigeon, Garat, Volney, Dupuis, Saint-Lambert, Laplace, Cabinis, De Tracy, J. B. Say, Benjamin Constant, Bichat, Lamarck, Saint-Simon, Thurot, Stendhal). Out of this school, in turn, developed the positivism of Comte. Ref. IEP
