After first reading The Naked Ape (at age 25) my judgement on life simplified. Each chapter lifted burdens of heavy confusion and sadness off my shoulders. I read the book five times. Even now, at 37, I go back to it when I'm feeling angry or betrayed or confused. I'm familiar with every paragraph; I absorbing each page almost at once. And with every reading, the truth of The Naked Ape strengthens and clarifies my life.
At the end of the book, Desmond Morris's final message tops anything ever written about the solution to our current, misconstrued "advanced" lifestyle. I won't spoil it and quote him. You'll need to read the book and find out for yourself (or get the book and read the final chapter if you're into short-cuts). But do yourself a gigantic good turn and start fresh from the beginning.
