MEYERSON, Émile. Polish thinker, b. in Lublin in 1859, d. in Paris on 4 Dec. 1933. He carried out his entire intellectual activity in France, devoted to the philosophy of science.
Principal works: Identité et réalité (Paris 1905); De l'explication dans les sciences (2 vols., ibid. 1922); La déduction relativiste (ibid. 1925); Du cheminement de la physique (3 vols., ibid. 1931); Réel et déterminisme dans la physique quantique (ibid. 1937). Opposing positivism, M. defended the ontological and explanatory value of science, which does not stop at the mere enunciation of laws but also applies the principle of causality, affirming the permanence in time of an unchanging reality beneath apparent becoming. This rationalization of the real, however, can never be complete, given the existence of the irreducible irrational within the scheme of pure mechanism.
