I decided to teach because I think that any person who studies philosophy has to be involved actively.
I am really only interested in new information, not freelance opinion. I don't really care what you think off the top of your head.
The great book for you is the book that has the most to say to you at the moment when you are reading. I do not mean the book that is most instructive, but the book that feeds your spirit. And that depends on your age, your experience, your psychological and spiritual need.
