G.W.F. Hegel

Hegel is the most ambitious philosopher in the Western tradition: he tried to describe the entire development of human consciousness, history, art, religion, and philosophy as the gradual self-realization of a single Spirit (Geist). Reality is not a collection of static substances; it is a process by which Spirit comes to know itself through us.

The engine of this process is the dialectic: every concept generates its opposite, and the tension between them is resolved at a higher level that preserves both. Master and slave, freedom and necessity, individual and community — each opposition propels history forward. To Hegel, history is not random; it is the progressive unfolding of freedom.

His prose is famously difficult. (Schopenhauer called him a charlatan; Russell called him almost certainly mistaken about almost everything.) But his influence is incalculable: Marx inverted him into historical materialism, the existentialists rebelled against him, and the very habit of thinking historically — of asking how an idea got to be what it is — is largely his bequest.
