Nature is satisfied with little; and if she is, I am also. - Benedictus de Spinoza

Herr Bauer picked out French materialism as a school of Spinoza from Hegel's History of Philosophy. But when he found in another of Hegel's works that deism and materialism are two parties with one and the same fundamental principle, he concluded that Spinoza had two schools which disputed over the meaning of his system.

...This divergence and perversion of the essential question is most striking in what goes today by the name of philosophy. There would seem to be only one question for philosophy to resolve: What must I do?

For example, in Kant's Critique of Practical Reason, or in Spinoza, Schopenhauer and specially Rousseau.
