The Joy of Sets: Fundamentals of Contemporary Set Theory (Undergraduate Texts in Mathematics)

Rating:
Summary: At times not so easygoing, but indeed a joy to read ...
Review: Anyone seeking a deeper understanding of the foundations of the mathematics will benefit from reading this excellent book.
Despite considerably abstract (almost no concrete examples), this book was carefully conceived to guide the reader through some of the most exciting contemporary ideas on set theory. If I had to name a minus about this book, I would mention the lack of solutions to the problems posted by the author. This makes the book a little less suitable for self-study.

Nevertheless, this book was written with care and love for the subject.
