Description

The Traite des systemes is a milestone in the intellectual history of the eighteenth century. This is a study of its content, structure, sources and importance. It includes a discussion of Condillac's analysis of good and bad systems, the adequacy of his knowledge and under- standing of the speculative metaphysics of the preceding century, the effectiveness of his method of attack on seventeenth-century metaphysical systems, his conception of empirical and scientific method, and in particular his understanding of the role of hypotheses, his application of the Newtonian scientific method to politics, physics, and the arts, and, finally, his preoccupation with the meaning of words and with the origin and purpose oflanguage. Speculative metaphysical systems, such as those of Descartes, Malebranche, Boursier, Leibniz and Spinoza, are attacked by Con- dillac, as are popular superstitions and prejudices, with the weapon of linguistic criticism. It is the systematic use of this weapon which makes the Traite des systemes more than a reflection of his contem- poraries' antipathy towards speculative metaphysics.
