Philosophy hasn't made any progress? - If somebody scratches the spot where he has an itch, do we have to see some progress? Isn't genuine scratching otherwise, or genuine itching itching? And can't this reaction to an irritation continue in the same way for a long time before a cure for the itching is discovered?

Philosophy limits the thinkable and therefore the unthinkable.

Our civilization is characterized by the word "progress." Progress is its form rather than making progress being one of its features. Typically it constructs. It is occupied with building an ever more complicated structure. And even clarity is sought only.

It is an hypothesis that the sun will rise tomorrow: and this means that we do not know whether it will rise.

A main cause of philosophical disease-an unbalanced diet: one nourishes one's thinking with only one kind of example.

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?

The philosopher is not a citizen of any community of ideas, that is what makes him a philosopher.
