I bet INTPs get really into philosophy because you are deep and intellectual. Do you have favorite books, philosophers or schools of thought?
I am rather hedonistic myself and I am a humanist. I don't know whether you would call it a philosophy or a religion-I call it the former- but I am recently into Science of Mind.
Also, thanks for your posts. I could spend hours reading them! I don't get much stimulating conversation in my daily life so I am always glad to get some.
