Philosophy unravels the knots in our thinking; hence its results must be simple, but its activity is as complicated as the knots that it unravels. - Ludwig Wittgenstein

Original German: Ein Satz kann unmöglich von sich selbst aussagen, dass er wahr ist.

The gramophone record, the musical thought, the score, the waves of sound, all stand to one another in that pictorial internal relation, which holds between language and the world.
To all of them the logical structure is common.
(Like the two youths, their two horses and their lilies in the story. They are all in a certain sense one.)

Concerning that which cannot be talked about, we should not say anything.
