Talk:Set Theory/Introduction

= NAVIGATING THE BOOK =

I noticed that navigating backwards in the book is not possible. The previous subject is shown but clicking results in no action. Why not ??

PS: Everything goes well until "Relations" is the previous page...

= INTRODUCTION= This introduction is historically wrong. Cantor was not the first to use formal systems - indeed I don't think he was interested.

What about Euclid and more to the point, proofs of the parallel postulate?
