Dancing in all its forms cannot be excluded from the curriculum of all noble education; dancing with the feet, with ideas, with words, and, need I add that one must also be able to dance with the pen?

The truth must be told, even if the world should be shivered in fragments.

There is no pre-established harmony between the furtherance of truth and the well-being of mankind.

The fervor about having the truth counts very little today in relation to that other fervor, more gentle and silent, to be sure, for seeking the truth, a search that does not tire of learning afresh and testing anew.

He who does not lie does not know what truth is.

The question whether truth is necessary, must not merely be affirmed beforehand, but must be affirmed to such an extent that the principle, belief, or conviction finds expression, that there is nothing more necessary than truth, and in comparison with it everything else has only a secondary value.
