Solution to the paradox of the russell.

Russell's paradox is a paradox that dictates the following: if we have a set that contains itself, then the set is not a set. The solution however is to accept that a set does not have to follow the rules of its individual parts, if there were a group of cacti all contained in a circle, and each individual cactus had a circle that contained only it, it would be possible that the cactus left their individual circle without leaving the group cactus.
