Abstract

Like any other product of human thought, a philosophical system is conditioned by the contingent circumstances of its origins, and especially by sense experience, the origin of all human cognition. Catholic philosophy, moreover, is conditioned by the doctrine of the Church. Because both sense experience and the Catholic faith are true to their respective objects, and because truth for one is truth for all, the conditioning of Catholic philosophy by its contingent origins does not entail a lack of universal validity. Such validity is in fact possessed by St. Thomas’s system, which is faithful both to Catholic doctrine and to the concrete facts of everyday experience.
