About me:

I studied physics and philosophy at the Jagiellonian University in Kraków, Poland, and received from this university PhD in philosophy in 1991 and habilitation in 2001. My current field of interest is metaphysics and philosophy of physics. I authored Intersubjectivity and Mathematical Intuitionism, Kluwer AP 1999, and Is Nature Deterministic? Jagiellonian UP, 2001. I also co-authored (with Nuel Belnap and Thomas Müller) Branching Space-Times; Theory and Applications Oxford UP, 2022.

My favorite quote   (Arthur Prior, 1914-1968, undated note);

“And I think it is important that people who care for rigorism and formalism should not leave the basic flux and flow of things in the hands of existentialists and Bergsonians and other who love darkness rather than light, but we should enter this realm of life and time, not to destroy it, but to master it with our techniques.”
