Cardinal Mercier’s A Manual of Modern Scholastic Philosophy is a standard work, prepared at the Higher Institute of Philosophy, Louvain, mainly for the use of clerical students in Catholic seminaries. Though undoubtedly elementary, it contains a clear, simple, and methodological exposition of the principles and problems of every department of philosophy, and its appeal is not to any particular class, but broadly human and universal.
Volume I includes a general introduction to philosophy and sections on cosmology, psychology, criteriology, and metaphysics or ontology.
Volume II contains sections on natural theology, logic, ethics, and outlines of the history of philosophy.
