"The unleashed power of the atom has changed everything save our modes of thinking, and we thus drift toward unparalleled catastrophes."
- Albert Einstein
Yet the best one is not from CIV5:
And when the hourglass has run out, the hourglass of temporality, when the noise of secular life has grown silent and its restless or ineffectual activism has come to an end, when everything around you is still, as it is in eternity, then eternity asks you and every individual in these millions and millions about only one thing: whether you have lived in despair or not.
- Søren Kierkegaard: The Sickness Unto Death, Datalinks
