Peter Kreeft is brilliant!
It usually takes a long time for me to read a book authored by Peter Kreeft because each paragraph (sometimes each sentence) is so profound that I have to put the book down and pace around my room in deep thought for half an hour, slowly digesting what I've just read!
This book is no exception. This book is all substance, there is no excess baggage or useless diversions, and it's beautifully expressed (a typical Kreeft experience). My knowledge of Ecclesiastes, Job and Song of Songs has always been limited and instinctual but when Kreeft is your lecturer your understanding explodes in all directions. It was an amazing experience to start in Ecclesiastes and finish in Song of Songs.
Every serious philosopher should read this.
