I act with complete certainty. But this certainty is my own.

Philosophers are often like little children, who first scribble random lines on a piece of paper with their pencils, and now ask an adult 'What is that?

I give no sources, because it is indifferent to me whether what I have thought has already been thought before me by another.

To convince someone of the truth, it is not enough to state it, but rather one must find the path from error to truth.

The sole remaining task for philosophy is the analysis of language.

The child learns to believe a host of things. I.e. it learns to act according to these beliefs. Bit by bit there forms a system of what is believed, and in that system some things stand unshakeably fast and some are more or less liable to shift. What stands fast does so, not because it is intrinsically obvious or convincing; it is rather held fast by what lies around it.

If, for example, you were to think more deeply about death, then it would be truly strange if, in so doing, you did not encounter new images.
