@Thom You wrote "However, I read some books on the ethics and anthropology of Karol Wojtyla. His philosophy is some kind of a mix between Thomism and personalism. I am not saying he made a mistake anywhere (I have not studied his opus extensively), but his personalistic philosophy seems rooted in the phenomenology of Husserl which is at least philosophically questionable." I found the perfect answer for this: see Peter Kreeft's paper above. I'm curious what you think since you trust Aquinas.
