The main aim of this paper is to provide an interpretative application of Józef Życiński’s philosophical work. I claim that one can find in Życiński’s thought criteria for evaluating certain positions which use platonistic concepts in order to solve specific problems in the context of philosophy of physics, especially philosophy of spacetime. After reconstructing Życiński’s philosophy, I use the derived criteria to evaluate positions of Howard Stein’s and Max Tegmark’s. I conclude that, according to criteria taken from Życiński’s philosophy, the former’s views are more plausible, and so create a better starting point in developing a platonistic structuralist position.
