"Парадоксы" и "псевдопарадоксы" (противоречия теории множеств и проблема определения числа)

The subject of the article is the so-called Russel's paradox. The two approaches and the two methods of solution of this "paradox" are contrasted. The first is the formal definitive method of Russel, his theory of types "prohibiliting" contradiction which is at the basis of the "paradox". The author puts forward and realizes another way - the method of classical dialectics which directs the search of the true form to level the existing contradiction.
