None of us can completely transcend our subjectivity and emotional allegiances to religious, cultural, and philosophical ideas. But in his painful and self-searching honesty, Walter Kaufmann comes close. This alone makes him a rare author.
However, for those who have read this book, and certainly for those who have also read some of his other books, Dr. Kaufmann's vast knowledge and subtle mind become obvious. This learnedness and intellectual prowess make his honesty that much more impressive (because he could easily have constructed intellectualized defenses of his favorite positions, as many others do). His brilliance also make his searching honesty that much more useful to the rest of us--for he has seen much, and in being honest about what he has seen, he has much to teach.
In addition to the honesty and brilliance of Kaufmann's writing, the writing is, at times, beautiful to the point of being poetic.
And, relatively speaking (for a book on philosophy) it is wonderfully accessible (clearly written).
If you have strong beliefs in any religion or world view, be prepared for a challenging, perhaps painful, read. But this pain is good pain--the pain of growing, the pain of life.
