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.
— Stanislaw Lesniewski
(1927). As quoted in Rafal Urbaniak, Leśniewski’s Systems of Logic and Foundations of Mathematics (2013), 113.

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
(1987) --
