§24. If you do not keep the multiplicity of language-games in view you will perhaps be inclined to ask questions like: "What is a question?"—Is it the statement that I do not know such-and-such, or the statement that I wish the other person would tell me....? Or is it the description of my mental state of uncertainty?—And is the cry "Help!" such a description?
Think how many different kinds of thing are called "description": description of a body's position by means of its co-ordinates; description of a facial expression; description of a sensation of touch; of a mood.
Of course it is possible to substitute the form of statement or description for the usual form of question: "I want to know whether...." or "I am in doubt whether...."—but this does not bring the different language-games any closer together.
The significance of such possibilities of transformation, for example of turning all statements into sentences beginning "I think" or "I believe" (and thus, as it were, into descriptions of my inner life) will become clearer in another place. (Solipsism.)
