The causal chain that ends up with totalitarian statism starts with the mysticism, collectivism, and statism of Plato, and is intensified with Hegel.

This mixture is incompatible with natural rights, limited government, and capitalism, but is compatible with nazism, fascism, socialism, communism, and Islamic theocracy.
