Resentment, born of weakness, harms no one more than the weak person himself. - Friedrich Nietzsche

We have art in order not to die of the truth.

The very reason [the Greeks] got so far is that they knew how to pick up the spear and throw it onward from the point where others had left it. Their skill in the art of fruitful learning was admirable. We ought to be learning from our neighbors precisely as the Greeks learned from theirs, not for the sake of learned pedantry but rather using everything we learn as a foothold which will take us up as high, and higher, than our neighbor.

Everyone who has ever built anywhere a new heaven first found the power thereto in his own hell.
