He who despises painting has no love for the philosophy in nature.

Greek philosophy seems to have met with something with which a good tragedy is not supposed to meet, namely, a dull ending.

In the eyes of dialectical philosophy, nothing is established for all times, nothing is absolute or sacred.

All thinking begins with wondering.

Ordinary people seem not to realize that those who really apply themselves in the right way to philosophy are directly and of their own accord preparing themselves for dying and death.

Love all, trust a few, do wrong to none.
