The scientific imagination always restrains itself within the limits of probability.
The gods have been good to you. But what the gods give they quickly take away. You have only a few years in which to live really, perfectly, and fully. When your youth goes, your beauty will go with it, and then you will suddenly discover that there are no triumphs left for you, or have to content yourself with those mean triumphs that the memory of your past will make more bitter than defeats. Every month as it wanes bring you nearer to something dreadful. Time is jealous of you, and wars against your lilies and your roses.
Men sometimes speak as if the study of the classics would at length make way for more modern and practical studies; but the adventurous student will always study classics, in whatever language they may be written and however ancient they may be. For what are the classics but the noblest recorded thoughts of man? They are the only oracles which are not decayed, and there are such answers to the most modern inquiry in them as Delphi and Dodona never gave. We might as well omit to study Nature because she is old. To read well, that is, to read true books in a true spirit, is a noble exercise, and one that will task the reader more than any exercise which the customs of the day esteem.

A finely tempered nature longs to escape from the personal life into the world of objective perception and thought.
