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.

Whatever has value in our world now does not have value in itself, according to its nature - nature is always value-less, but has been given value at some time, as a present - and it was we who gave and bestowed it.

The value of a thing sometimes lies not in what one attains with it, but in what one pays for it - what it costs us.

We do not place especial value on the possession of a virtue until we notice its total absence in our opponent.

The value of many men and books rests solely on their faculty for compelling all to seek out the most hidden and intimate things.

I try to spend my time on areas that I think are important for the future, and where I think I can add value.
