Nieztsche

Nietzsche is commonly categorised as an Existentialist, and it's true that many of his ideas fall into that category. However, he does have a ancient determinist view of human behaviour, which is the polar opposite to the (other) Existentialists. He is also the Existentialist with the richest philosophy and critique. I write about him the most so regardless of philosophical categories, he has his own page for organisational purposes.
