Fire-Hunter by Jim Kjelgaard is a good book about a man and a woman in prehistoric times who get kicked out of their hunter-gatherer tribe — the man, basically for the “sin” of independent thought; the woman, for being injured. While the tribe was bound by tradition and magic, the man and woman have to learn to survive by independence and induction. Whether they succeed or not, and how, I won’t say: I don’t want to give away too much. The book has some illustrations of being first-handed and using reason as a tool of survival. Recommended.
