What is a list of formal textbook that i need to impose myself to read as a prerequisite before start reading a book called lectures of logic and set theory vol.1 by George Tourlakas?
That book is too challenging for me start to read as i didn't take any logic class before.
You could check out the Teach Yourself Logic guide to the logic literature, downloadable at http://www.logicmatters.net/tyl -- the full PDF version gives extended descriptions about what is covered in what book, and should enable to find what you need depending on your background/mathematical competence.
