This book has held up well over half a century, tackling the unanswerable question with the authority and pragmatism of a survivor of four concentration camps. Of course I started it thinking "Really?", but it won me over with insights that feel immediately applicable to my own life, which I feel has been slowly shifting from the pursuit of means to meaning over the years. Don't get scared off by part II if you read it - that's where the practical information is.
