What is the solution to Russell's paradox?

Answer 1

That depends on whether you want to know the solution the mathematicians arrived at or the correct solution, the solution the mathematicians arrived at is that a set that contains itself is not a set, a false answer given the definition of a set. (sum of part), if you want to know the correct answer, it is that a set does not have to follow the rules of some individual pieces in question, if, for example, there were a group of cacti, each cactus within a circle, and there was a circle within the which were all the cacti, it would be possible for each cactus to leave its individual circle without the group leaving its circle.
