If it purports to establish a foundation for mathematics, it seems to me its methods need to be different from mathematical methods. However, I have the uneasy feeling that one still is doing mathematics when studying mathematical logic. In spite of all this ambivalence, I think it presents a rather satisfying foundation for other branches of mathematics such as abstract algebra. It then seems to be a pretension to think that mathematical logic offers a foundation for "all" mathematics; maybe, philosophy can help with this matter.</p>
