Nothing is more important than the formation of fictional concepts, which teach us at last to understand our own. - Ludwig Wittgenstein

Philosophy may in no way interfere with the actual use of language; it can in the end only describe it.

For it cannot give any foundation either.
It leaves everything as it is.

The meaning of a question is the method of answering it: then what is the meaning of 'Do two men really mean the same by the word "white"?' Tell me how you are searching, and I will tell you what you are searching for.

But some of the greatest achievements in philosophy could only be compared with taking up some books which seemed to belong together, and putting them on different shelves; nothing more being final about their positions than that they no longer lie side by side. The onlooker who doesn’t know the difficulty of the task might well think in such a case that nothing at all had been achieved.
