I want to start to study logic on my own to the level that I can understand a book like Enderton's and Michael Potter's Set Theory and Its Philosophy, also be able to study mathematical logic like recursive functions and model theory and Understand Logicist Reduction and why It failed because of Godel. Suppose that I've read nothing on logic and I'm not fair in math, but I want to be good at it.
I'll be gleeful if you introduce me a series of books on a) Introductory books on logic followed by more professional ones, b) Mathematics of logic, c) books on Logicist Reduction and Godel or what is necessary to understand them.
I have a plenty of time to study all these and will face all the troubles.
Thank You Very Much
