Good Intro to Philosophy
Format: Paperback
There’s a lot to this book, if you haven’t read anything by Dostoyevsky before this book could be a little challenging to get into, that being said it was a very good read and a real page turner. There’s some really good stuff in there that is broken down into plain English. Some of the shorter quotes I think were beautiful especially the ones about self reliance and motivations for someone to cling onto religion.
