I love this series.
The cat here represents the philosopher. He observes and questions, sometimes destabilizing the other characters. This book is, to me, a fun way to witness human limitations in reasoning. It's not a book to learn about the Jewish religion, it's just a book that is taking place in a Jewish community, if you catch the nuance. It's full of wit, and I laughed quite a lot. It's a great and fun book if you like critical thinking.
