I'm reading The Philosophy of the Enlightenment by Cassirer. It was finished in 1932 by a germen. It puts the ideas of the enlightenment in a historical framework that makes the whole intelligible. It's very good. I wish I could read it faster though, but its dense in substance to takes me longer to beat by beat understand it. I wish it was 7 years younger though, then it would be in the public domain and I could give it a systematic analysis chapter by chapter in my book. Oh well. I'll just take a few choice quotes from it instead.
