Abstract

One can say about two sources of philosophy of nature created at the Catholic University of Lublin. One of them was the Theological Faculty at the Warsaw University in the 50s of the previous century. The scientific climate functioning in it induced Rev. Stanisław Mazierski to put through a profound examination the traditional style which then dominated in cultivating philosophy of nature. That analysis showed necessity of opening philosophy of nature to achievements of the contemporary science, especially of mathematical and physical structure. The second source constitutes the Faculty of Natural Sciences of the Mary Curie- Skłodowska University in Lublin and the Holy Cross Mountains. Rev. Włodzimierz Sedlak, bewitched by nature, by its mysteries and by contemporary science investigating them, and endowed with the enormous intuition, interlocked a lot of scientific domains, forming a whole and proposing a fascinating view of the world. Some people were alarmed by it, some others were even resentful of it. The both above-mentioned sources, mutatis mutandis, exist till the present day. Each of them, in spite of their dissimilarity (taking into account at least different personalities of the both protagonists of philosophy of nature created at the Catholic University of Lublin) demands philosophy of nature to be an unconventional, and made in novel fashion, form of \"philosophizing over this nature\". These both styles of \"philosophizing over nature\" have been enriching themselves and have been evolving and prospering. They are present and alive among continuators of the protagonists\' work. The contemporary philosophy of nature, being still created in Lublin, is the only one, when comparing it to that of performed at other universities of this country and of the world outside
