I measured the skies, now the shadows I measure, Sky-bound was the mind, earth-bound the body rests. [Kepler's epitaph]
Interpretation
This quote reflects the duality of human existence, where the mind seeks to explore boundless ideas while the body remains tied to earthly limitations.
Johannes Kepler's epitaph poignantly captures the contrast between the limitless aspirations of the human mind and the inevitable constraints of the physical body. It suggests that while our intellect and imagination can reach for the heavens and understand the cosmos, our mortal existence keeps us grounded. This duality invites reflection on the nature of human ambition and the tension between our desires and our reality.

Whether it is to be read by the people of the present or of the future makes no difference: let it await its reader for a hundred years, if God himself has stood ready for six thousand years for one to study him.
Eyesight should learn from reason.
It may be well to wait a century for a reader, as God has waited six thousand years for an observer.
Moral philosophy is nothing else but the science of what is good, and evil, in the conversation, and society of mankind. Good, and evil, are names that signify our appetites, and aversions; which in different tempers, customs, and doctrines of men, are different.
Our ancestors... purged their guilt by banishment, not death. And by so doing, they stopped that endless vicious cycle of murder and revenge.
We have been basically persuaded that we should not talk about racism.
However strong, however imposing a ship may appear, it is not 'disgraced' because it flies before the tempest. A commander ought always to remember that a man's life is worth more than the mere satisfaction of his own pride. In any case, to be obstinate is blameable, and to be wilful is dangerous.
I feel shame, not for the wrong things I have done, but for the right things that I have failed to do.
