St. Edith Stein, born in 1891 in Breslau to a practicing Jewish family, she lost her faith in her teens. A brilliant student, she became only the 2nd female in Germany to get a PhD in philosophy writing her thesis on empathy under the phenomenologist Huserl. In 1921 however, after her experiences as volunteer nurse in WWI and a reading of the Life of St. Teresa of Avila she converted to Christianity. In 1933 she became a Carmalite nun until she was martyred in Auschwitz in 1942. She was canonized a Saint by Pope John Paul in the 1990s. Some quotes from the introduction of Finite and Eternal Being (from the gasp library). In this book, (or at least the introduction) it begins:
A preliminary exposition of the doctrine of act and potency of St. Thomas Aquinas is to serve as a an avenue of approach. [the remainder of the paragraph elided ]
The distinction between potency (possibility, faculty, power) and act (actuality, actualization, efficacy) is related to the ultimate problems of being. And the discussion of these concepts leads immediately into the heart of Thomistic philosophy.
On the the point of my quotes here:
Much more serious is the complete separation of modern philosophy from revealed truth. It [ed: philosophy] no longer sees in revealed truth a standard of measurement with which to test its own findings. Nor is it willing to have theology assign to it certain tasks for the solution of which philosophy would then have to use its own specific ways and means. It not only considers it a duty to confine itself to the natural light of reason but it is determined never to reach out beyond the world of natural experience. It wants to be an autonomous discipline in every respect. This ambition has cause modern philosophy to become to a large extent a godless discipline. And it has led, moreover, to the division of philosophy into two separate camps in which two different languages are spoken and in which no attempt is made to arrive at a mutual understanding.
While it is true that the physical sciences have good call to reject revelation as part of their discipline, philosophy has less call for its failure to address the same.
