Abstract
The argument of this paper suggests that for the last hundred years or so fundamental premisses of logic have been incorrect. From these premisses a vast superstructure has been developed which, it would seem, is no more meaningful than a game such as chess.The basic errors in current class theory, it seems to me, have impeded progress in the fields of mathematics and logic. I am certain that on the theory proposed, the correct definition of a natural number can be provided. I can, in fact, provide this. What benefits it will bring to logic only time will tell.Of the greatest importance is the fact that if the theory is true, at last, there will be a firm link between the Humanities and the Sciences
