The deeper and more anylalitic the better. I took a lot of philosophy classes in college. I am pretty familiar with the works of most philosophers so I am not looking for those kinds of recommendations.
I always find books about Platoism and comparison of different philosophers interesting. But I'm pretty open to anything.
The last book I read was The Cave and the Light by Arthur Herman if you know of the anything similar I would appreciate it.
