It was all too easy to make things up, it was like skating on thin ice, it was like doing dainty pirouettes on a brittle crust over water thousands of fathoms deep.

A philosopher knows that in reality he knows very little. That is why he constantly strives to achieve true insight. Socrates was one of these rare people. He knew that he knew nothing about life and about the world. And now comes the important part: it troubled him that he knew so little.

Throughout the entire history of philosophy, philosophers have sought to discover what man is - or what human nature is. But Sartre believed that man has no such eternal nature to fall back on. It is therefore useless to search for the meaning of life in general. We are condemned to improvise. We are like actors dragged onto the stage without having learned our lines, with no script and no prompter to whisper stage directions to us. We must decide for ourselves how to live.

Moreover, nature's blocks had to be eternal-because nothing can come from nothing.
