Who is The Free Man from The Ethics of Ambiguity and what is their importance?

The Free Man man exists in a paradoxical state of striving to transcend his being despite being trapped into certain social roles by the world. Being free requires not being trapped into those roles, such as the role of the Serious Man who locates his values outside of himself. The free man is somehow self-determining or autonomous and recognizes himself as his own absolute. The free man also avoids being trapped in monotony and embraces spontaneity. He does not divide the world into black and white but instead accepts the ambiguity of the world and the ambiguity of his own identity.
