“No self is of itself alone. It has a long chain of intellectual ancestors. The "I" is chained to ancestry by many factors … This is not mere allegory, but an eternal memory.”
Writings of July 1918, quoted in A Life of Erwin Schrödinger (1994) by Walter Moore

“Eternity is a mere moment, just long enough for a joke.”
Source: Steppenwolf (1927), p. 97
Context: You should not take old people who are already dead seriously. It does them injustice. We immortals do not like things to be taken seriously. We like joking. Seriousness, young man, is an accident of time. It consists, I don't mind telling you in confidence, in putting too high a value on time. I, too, once put too high a value on time. For that reason I wished to be a hundred years old. In eternity, however, there is no time, you see. Eternity is a mere moment, just long enough for a joke.
