Born Nov. 21, 1851, in Brainel’Alleud, Brabant; died Jan. 23, 1926, in Brussels. Belgian religious philosopher and church figure.
Mercier was a professor of philosophy at the University of Louvain (1882-1906), a Catholic archbishop (from 1906), and a cardinal (from 1907). He played a great role in the genesis of neo-Thomism. In Louvain he established the Higher Institute of Philosophy, or the School of Thomas Aquinas, in 1888. He founded the Thomist journal Revue neo-scolastique in 1894 (called Revue philosophique de Louvain since 1946) and helped to convert Louvain into an international center of neo-Thomism.
