PHILOSOPHICAL PERIODICALS. 137 chean Ethics, St. Thomas unfolds this content. The order which the intellect seeks to understand is realised, says St. Thomas (1) in nature (ordo quern ratio non facit sed soluni considerat). The truths of the natural order are ranked under metaphysics, mathematics and physics ; (2) in the acts of will, or the moral order, the object of moral philosophy (ordo quern ratio considerando facit in actibus voluntatis) ; (3) in the acts of mind, or the logical order, the object of logic (ordo quern ratio con- siderando facit in proprio actu) ; (4) in exterior actions, or the order of the mechanical and fine arts (ordo quern ratio considerando facit in rebus constitutis per rationem hunianaui). M. De Wulf regards the classifica- tion given by St. Thomas as the true classification of the philosophical sciences and, in the present article, enters upon its exposition and defence.
