Rev. Prof. Józef Iwanicki (1902-1995) was the co-founder (together with Rev. Prof. Kazimierz Kłósak) and the first editor-in-chief of the SPCh. From 1925 he studied mathematics, philosophy and theology in Strasbourg. He obtained his doctorate in 1933. He then studied 17th-century philosophy at the Ecole des Hautes Etudes under Prof. A. Koyrè. At the same time, he worked at the College de France under Professor E. Le Roy and at the Sorbonne under Professor L. Brunschvigg. After returning to Poland in 1935, he worked at the Higher Seminary in Włocławek, where he taught logic, theodicy and ontology until the war. He was ordained a priest in 1936. During the German occupation, he took part in secret teaching. In 1945, he returned to Wloclawek and took up lectures in logic and history of philosophy at the reactivated seminary. From 1946, he lectured in logic at the Faculty of Catholic Theology at the University of Warsaw, and also took up lectures in methodology at the Faculty of Christian Philosophy at the Catholic University of Lublin. In 1952, he was given the post of associate professor at the Catholic University of Lublin. After the arrest by the Security Office of the then Rector of the Catholic University of Lublin, Fr Antoni Słomkowski, he was elected Rector of the Catholic University of Lublin, a position he held until October 1956. After the establishment of the Academy of Catholic Theology in Warsaw in 1954, he became its full professor and head of the Department of Theoretical and Experimental Psychology. From 1965 to 1972 he was the rector of ATK. He was associated with the movement of patriotic priests. His grave is located in the municipal cemetery in Włocławek. Rev. Prof. Józef Iwanicki continued the thought of the so-called Cracow Circle, aiming at renewing Thomism through mathematical logic. In his scientific work, Rev. Ivanicki suffered severe losses during the war. In 1939, he completed a book on investigation according to Descartes, Arnold, Pascal and Malebranche, the manuscript of which, together with his notes, was destroyed by the Germans. During the occupation, while in Warsaw, he prepared an extensive work on Cartesian methodology for publication, but this scholarly output did not see the light of day either, as it was lost during the Warsaw Uprising. Rev. Prof. Józef Iwanicki's scientific interests included psychology, logic, especially the issue of the systematisation of formal logic and the application of logic in philosophy. He began his research with a thorough critique of solutions known from history, followed by constructive attempts. He achieved valuable results in natural deduction, syllogistics and in the applications of formal logic in the philosophy of God. "From university staff, in all positions, he demanded (I repeat: demanded) hard work and commitment to the university. In this respect, he was very demanding. (...) he lived the Academy and its affairs. When he retired, he was not only interested in the fate of the Academy, but also organised meetings at his home, encouraging those gathered to work hard for the development of the Academy. He rejoiced at every achievement in this field. It was like this until almost the last moments of his life" (M. Lubański - from the homily given during the funeral of Rev. Professor Józef Iwanicki, 8.08.1995). He served as editor-in-chief of the SPCh from 1965 to 1973, and published 6 articles and 6 book reviews in the SPCh. The philosophical output of Józef Iwanicki was devoted to a fragment of No. 1 of SPCh from 1973. More see: Z. Pawlak, Działalność naukowo-organizacyjna ks. prof.
