I was at the Half Priced Books on lane avenue looking for something by Seneca when a helpful man suggested that I have a look at this book. He pointed out that "much of it was drawn from seneca and his stoic philosophy." It was only $4 so I obliged. I'm glad that I did.
This book traces an arc through philosophy: Socrates -> Epicures -> Seneca -> Montaigne -> Schopenhauer -> Neitzche. It was my first exposure to Montaigne and Schopenhauer and taught me that I knew very little about Socrates, Epicures, and Neitzche. The language of the book made what is typically a very difficult subject very approachable.
Highly recommended for anyone who wondered why the heck we should give a crap about the famous thinkers of history.
