“If anything is certain, it is that I myself am not a Marxist.[In a letter about the peculiar 'Marxism' which arose in France 1882]”

“The trouble is that the Marxists in our country are ignorant of the real Marxism... They supress... Phony Marxists they twist [data] because they have pre-conceived notions which they want to [prove]”

You do not want me to be thinking about what I am, but about what You are. Or rather, You do not even want me to be thinking about anything much: for You would raise me above the level of thought. And if I am always trying to figure out what I am and where I am and why I am, how will that work be done?”
