Abstract
This paper explores the mode of thinking that should characterize philosophers who happen to be Catholic or Catholics who also are philosophers. How does and how should a “Catholic philosopher” relate to the human — i.e., the earthly, interpersonal, social, religious, historical — world in which he or she practices what, for more than 2,500 years and notwithstanding several transformations, has been called “philosophy”? In trying to prepare an answer to this question, this paper focusses on the universality or Catholicity of the truth that orients and dominates the philosophical search, but without ignoring the fact that at least certain aspects of that same truth are also sought along non-philosophical paths.
