Science Quotes by Stanislaw Lesniewski (1 quote)
Being of the opinion that, if an object is the class of some a (e.g., people, points, square circles), then it actually consists of a, I always rejected … the existence of theoretical monstrosities like the class of square circles, understanding only too well that nothing can consist of something which does not even exist.
