If I make up the definition of a mammal, and then, after inspecting a camel, declare "look, a mammal' I have indeed brought a truth to light in this way, but it is a truth of limited value.

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.

Truth alone will endure, all the rest will be swept away before the tide of time.

All things are subject to interpretation whichever interpretation prevails at a given time is a function of power and not truth.

Words are but symbols for the relations of things to one another and to us; nowhere do they touch upon absolute truth.

It is good to express a thing twice right at the outset and so to give it a right foot and also a left one. Truth can surely stand on one leg, but with two it will be able to walk and get around.
