Stanisław Krajewski, born in Warsaw, Poland, in 1950, obtained PhD in mathematics in the Institute of Mathematics of the Polish Academy of Sciences, later Habilitation degree in philosophy at the Faculty of Philosophy and Sociology of the University of Warsaw, and then the state-conferred title of professor of humanities. He has become ordinary professor at the University of Warsaw. He was chairing the Academic Council of the Institute of Philosophy of the University of Warsaw in 2012-2020.
Krajewski has been working in several disciplines: mathematical logic, the foundations of mathematics, philosophy of mathematics, philosophy of mind, philosophy of dialogue, philosophy of religion, Jewish experiences, interfaith dialogue, history of logic, history of Polish Jews. He has published papers and books also on the borderline of philosophy and other domains. He also co-authored the post-World War II section of the core exhibition in POLIN, the Museum of the History of Jews in Poland, opened in 2014.
Over 30 years ago he co-founded the Polish Council of Christians and Jews, and has been its co-chairman since then. He was also a member of the International Council of the Museum of Memorial Auschwitz-Birkenau. For several years he served on the board of the Union of Jewish Communities in Poland.
Krajewski organized international conferences in which top experts participated, for example, “Abraham Joshua Heschel. Philosophy and Inter-religious Dialogue: Between Poland and America” (Warsaw, 2007), “Theology in Mathematics?” (Cracow, 2014), and he chaired the academic committee of the congress “Logic and Religion” (University of Warsaw, 2017). He participated in philosophical-theological projects like “Contemporary Jewish Theology of World Religions” (led by Rabbi Alon Goshen-Gottstein from Jerusalem) and “Learned Ignorance Trialogue” (led by Father James L. Heft from California).
Indication of main scientific achievements
In 1970s, Stanislaw Krajewski introduced “satisfaction classes” (coding truth in non-standard models of first order number theories) as an object of study in its own right. (Before that they had been occasionally used only as an instrument in proofs.) Several of his studies are devoted to philosophical consequences of Gödel’s theorems. In particular, he analyzed the anti-mechanist arguments of Lucas and Penrose, arguing – as do other logicians – that neither Gödel’s theorem alone nor other similar results are sufficient for the proof that human mathematical power is greater than that of any machine or program. He also indicated Gödel’s work as a source of the phenomenon of “emergence” in mathematics.
He introduced a new term, „suprasubjective existence,” in relation to mathematical concepts. It is more than intersubjective existence but less than objective existence, since no assumption is made of any presence of objects independent of the subject.
He studied relatedness logic, introduced by R.L. Epstein. He has also dealt with the history of logic on Poland, being the biographer of two logicians who were his teachers, the mathematician Andrzej Mostowski and the philosopher Andrzej Grzegorczyk.
Krajewski has explored the relationships of mathematics and theology. He introduced as a research topic the presence of theological motives in mathematics. While using mathematical models in theology is risky they can serve as illustrations; he proposed a novel model based on projective geometry.
Krajewski has also studied interfaith dialogue as a religious phenomenon. He has proposed the concept of “deep dialogue” as dialogue without any expectations with regard to the religiosity of the dialogue partner; in other words, it is an intentionally intentionless relation. He also analyzed the relationship of interreligious dialogue with the thought of philosophers of dialogue – Martin Buber, Franz Rosenzweig, Emmanuel Levinas, and also Abraham Joshua Heschel. He also showed that Heschel is the precursor of the Jewish pro-Christian declaration “Dabru emet” of 2000 (which Krajewski signed and popularized in Poland). Two volumes honoring him, with papers in English, have appeared: the issue of Edukacja Filozoficzna 68/2019 (http://www.edukacja-filozoficzna.uw.edu.pl/en/nr-682019/) and Philosophical Approaches to the Foundations of Logic and Mathematics. In Honor of Stanisław Krajewski, ed. by Marcin Trepczyński, Brill, Rodopi, Leiden, Boston 2021.
