Can anyone read this and not think it is a complete and utter load of tripe? I am all for a complete rethink in the way we think about philosophical logic, predicate calculus, the notion of a proof and the fact that we waste and misuse so many aspects of the philosophy of mathematics but how exactly does the philosophy that it is ok to derive significant parts of mathematics from logic save the world?
