Abstract

Émile Meyerson (1859–1933) is an epistemologist, in the French meaning of the term: he himself introduced the word in French as a synonymous for “philo- sophy of science” in his major book of 1908 Identity and Reality. First educated as a chemist, Meyerson discovered philosophy while reading Auguste Comte’s Cours de philosophie positive. However, he strongly rejected Comte’s positivism: metaphysics, he said, penetrates science and even common sense; men, whether they are scien- tists or not, are interested in finding a cause behind the stream of phenomena. This anti-positivism is justified in so far as Meyerson used the same method and pursued the same goal as Comte: the philosopher must practice an “a posteriori analysis of the products of thought”, so as to determine the laws of human mind. Consequently, Meyerson’s work is not a mere philosophy of science, it is more than an “épistémolo- gie” in the French sense. Its ambition is to reach the intellectual basis of all thought. The philosopher can resort to the resources of metaphysics to reach the psychologi- cal foundations of humanity, when he reflects on the historical products of thought. He establishes the transcendent or metaphysical logic involved in the process of thought. Meyerson’s work consequently deserves the name its author eventually gave to it in his posthumous Essais: a “philosophy of intellect”. But is such a philoso- phy wide enough to embrace the meaning of all the products of human thought? It seems that Meyerson was embarrassed and limited by his very starting point, namely Comte’s system. I argue that scientific or common conceptions may need more than the anti-positivist claim of the preservation of one substance behind phenomena. Truth to tell, men generally tend to identify a large and rich configuration of causes or substances. Only such architectonics can give an idea of what people mean by invoking their “vision of the world”.
