Wealth is the ability to fully experience life.

Men talk glibly enough about moonshine, as if they knew its qualities very well, and despised them; as owls might talk of sunshine,--none of your sunshine!--but this word commonly means merely something which they do not understand,--which they are abed and asleep to, however much it may be worth their while to be up and awake to it.

For what are the classics but the noblest 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.

Men do not fail commonly for want of knowledge, but for want of prudence to give wisdom the preference.

What we need to know in any case is very simple.

How many fine thoughts has every man had! How few fine thoughts are expressed!

He who is only a traveler learns things at second-hand and by the halves, and is poor authority. We are most interested when science reports what those men already know practically or instinctively, for that alone is a true humanity, or account of human experience.
