My favorite poet was Aeschylus. He wrote: "In our sleep, pain which cannot forget falls drop by drop upon the heart until, in our own despair, against our will, comes wisdom through the awful grace of God."
Aeschylus is not impersonal but transpersonal, a believer in fate and moral responsibility at the same time .
Archimedes will be remembered when Aeschylus is forgotten, because languages die and mathematical ideas do not. "Immortality" may be a silly word, but probably a mathematician has the best chance of whatever it may mean.
