Roughly speaking: objects are colourless - Ludwig Wittgenstein

This book will perhaps only be understood by those who have themselves already thought the thoughts which are expressed in it-or similar thoughts. It is therefore not a text-book. Its object would be attained if it afforded pleasure to one who read it with understanding.

It is difficult to describe paths of thought where there are already many paths laid down, and not fall into one of the grooves

What I give is the morphology of the use of an expression. I show that it has kinds of uses of which you had not dreamed. In philosophy one feels forced to look at a concept in a certain way. What I do is suggest, or even invent, other ways of looking at it. I suggest possibilities of which you had not previously thought. You thought that there was one possibility, or only two at most. But I made you think of others. Furthermore, I made you see that it was absurd to expect the concept to conform to those narrow possibilities. Thus your mental cramp is relieved, and you are free to look around the field of use of the expression and to describe the different kinds of uses of it.
