Philosophy is the self-correction by consciousness of its own initial excess of subjectivity.

You cannot be wise without some basis of knowledge, but you may easily acquire knowledge and remain bare of wisdom.

Seek simplicity, and distrust it.

A philosopher of imposing stature doesn't think in a vacuum. Even his most abstract ideas are, to some extent, conditioned by what is or is not known in the time when he lives.

Learning preserves the errors of the past as well as its wisdom.

Thus the negative perception is the triumph of consciousness.

The tragedy of the world is that those who are imaginative have but slight experience, and those who are experienced have feeble imaginations.
