59 Yet the Thomistic and neo-Thomistic revival was not the only sign of a resurgence of philosophical thought in culture of Christian inspiration. Earlier still, and parallel to Pope Leo's call, there had emerged a number of Catholic philosophers who, adopting more recent currents of thought and according to a specific method, produced philosophical works of great influence and lasting value. Some devised syntheses so remarkable that they stood comparison with the great systems of idealism. Others established the epistemological foundations for a new consideration of faith in the light of a renewed understanding of moral consciousness; others again produced a philosophy which, starting with an analysis of immanence, opened the way to the transcendent; and there were finally those who sought to combine the demands of faith with the perspective of phenomenological method. From different quarters, then, modes of philosophical speculation have continued to emerge and have sought to keep alive the great tradition of Christian thought which unites faith and reason.
