A certeza é por assim dizer um tom de voz em que alguém declara como são as coisas, mas não se infere desse tom que tem razão. - Ludwig Wittgenstein

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.)

Die Probleme werden gelöst, nicht durch Beibringen neuer Erfahrung, sondern durch Zusammenstellung des längst Bekannten. Die Philosophie ist ein Kampf gegen die Verhexung unsres Verstandes durch die Mittel unserer Sprache.
