Language disguises thought.

Philosophy aims at the logical clarification of thoughts. Philosophy is not a body of doctrine but an activity. A philosophical work consists essentially of elucidations.

Uttering a word is like striking a note on the keyboard of the imagination.

Here the term 'language-game' is meant to bring into prominence the fact that the speaking of language is part of an activity, of a form of life.

Philosophy can be said to consist of three activities: to see the commonsense answer, to get yourself so deeply into the problem that the common sense answer is unbearable, and to get from that situation back to the commonsense answer.

A philosophical problem has the form: I don't know my way about.

Think of words as instruments characterized by their use, and then think of the use of a hammer, the use of a chisel, the use of a square, of a glue pot, and of the glue.
