Identité et réalité
📖 Summary
Published in 1908 by the influential philosopher and chemist Émile Meyerson, Identite et realite stands as a monumental work in the philosophy and history of science. Spanning 462 pages of rigorous general non-fiction inquiry, the book investigates the fundamental psychological and rational mechanisms that drive scientific thought, specifically focusing on how human beings attempt to comprehend the external world. Meyerson argues that the primary impetus of scientific investigation is the search for identity, or the persistent human desire to discover an underlying permanence beneath the constant flux of sensible phenomena. At the heart of Meyerson's thesis is the interaction between two central concepts: law and cause. He contends that science naturally tends toward the elimination of diversity and change by asserting that the future is identical to the past, and that cause and effect are essentially tautological. When scientists explain a phenomenon by demonstrating that it is governed by a physical law, they are identifying regularity; however, true causal explanation, according to Meyerson, requires an identification of the antecedent with the consequent. In other words, the intellect seeks to prove that the effect is nothing more than the cause transformed, preserving substance and matter through various alterations. Throughout the text, Meyerson examines the evolution of scientific concepts, drawing heavily from the history of physics, chemistry, and philosophy. He analyzes the works of historical thinkers and classical scientists to illustrate how theories of matter, motion, and energy reflect this deep-seated psychological need for identity. Even when empirical reality resists complete rationalization—presenting anomalies, irrational elements, and irreducible diversity—the scientific mind continues its quest to equate things that appear different. Meyerson famously characterizes the irrational in nature as that which resists this identification, serving as a persistent check against purely deductive systems. Ultimately, Identite et realite challenges the purely empirical or purely conventional views of science popular at the turn of the twentieth century. Meyerson demonstrates that science is neither a simple accumulation of brute facts nor a mere set of convenient mathematical fictions. Instead, it is a deeply human enterprise driven by an ontological instinct to find reason and permanence in a changing universe. By dissecting the logical structures underlying scientific discovery, Meyerson provides a profound meditation on the limits of human knowledge and the persistent gap between our concepts and the absolute reality they seek to capture.
