Abstract

Constantin Leonardescu (1844–1907) was a professor of philosophy for 34 years at the University of Iași. He was an adept of the French eclectic spiritualism, which he tried to reconcile with the positivism of Herbert Spencer and with the Darwinism of Ernst Haeckel, while countering Vasile Conta’s brand of scientific materialism. Leonardescu argued against the positivist tenet of the incompatibility of metaphysics and positive science, based on the emergence of new “partial” or “local” metaphysics in the thought of contemporary genuine scientists, who philosophized disregarding the former metaphysical tradition, using only the concepts of their own disciplines and forging their own principles. Positive metaphysics exists thus potentially, the metaphysician’s task being to systematize, or to “reconcile” the local contributions of the scientists-philosophers in the framework of a general, unifying theory. This framework, he argues, is a generalization of “Darwinism”, that is, of the special metaphysics initiated by Darwin, then rendered general by Spencer and most importantly by Haeckel. However, philosophical Darwinism or “evolutionary monism” curiously vindicates, in Leonardescu’s view, traditional spiritualism. Generalized Darwinism thus interpreted offered a fundamental theory in which science could achieve systematic unity and become a true mirror of the Totality, which is metaphysics’ true object. Scientific metaphysics is principally a reflection upon science, taking as starting point the positive facts recognized as such by the sciences, and the empirical generalizations validated within each science, and aiming to ensure logical coherence amongst them, under the rule of the supreme evolution-principle.
