Quora answer: Who are the most under-appreciated and overlooked philosophers of any era?

Eric Hoffer http://en.wikipedia.org/wiki/Eric_Hoffer

Longshoreman and Philosopher. They don’t make them like that anymore.
————————————————————————————–
Instead we have to have Psychoanalyst Philosophers like Zizek and Badiou.
And some, like Badiou (http://en.wikipedia.org/wiki/Alain_Badiou), are running around with really terrible social ideas based on Maoism, or some other strange and esoteric type of communism, when we used to have philosophers like Eric Hoffer who did real work and also thought. Hoffer warned us about philosophers like Badiou. There just are not many real philosophers like that anymore. Socrates went to war. He was a gadfly, but he held his own among the Athenians of his day. And Hoffer’s philosophy was something that did not turn your stomach like so many of those who pretend to be philosophers these days. His philosophy was rooted in the promise of America. His was a real pragmatism. An American original.
