From principles is derived probability, but truth or certainty is obtained only from facts.

Energy

Is it a fact -- or have I dreamt it -- that, by means of electricity, the world of matter has become a great nerve, vibrating thousands of miles in a breathless point of time?

Happiness

Happiness is a butterfly, which, when pursued, is always just beyond your grasp, but which, if you will sit down quietly, may alight upon you.

Honesty

No man, for any considerable period, can wear one face to himself, and another to the multitude, without finally getting bewildered as to which may be true.

Light

Moonlight is sculpture.

Perspective

Nobody, I think, ought to read poetry, or look at pictures or statues, who cannot find a great deal more in them than the poet or artist has actually expressed. Their highest merit is suggestiveness.

Shame

See! those fiendish lineaments graven on the darkness, the writhed lip of scorn, the mockery of that living eye, the pointed finger, touching the sore place in your heart! Do you remember any act of enormous folly, at which you would blush, even in the remotest cavern of the earth? Then recognize your Shame.
