A great, concise plea to advance mankind's behavior in the era of powerful technology. Much of what Szent-Györgyi discusses is still politically and scientifically relevant today, but there are cases of historical events since the books publication significantly shifting the context of the book (but mostly in interesting ways, not invalidating the core message of the text). His optimism in scientific thinking is painful to read, knowing how short we've come up.

In the appendix of my copy is a "Psalmus Humanus" along with six humanist prayers from the author.
