For science is ... like virtue, its own exceeding great reward.
Those clouds are angels' robes.
All we need to make us really happy is something to be enthusiastic about.
Love can make us fiends as well as angels.
Take comfort, and recollect however little you and I may know, God knows; He knows Himself and you and me and all things; and His mercy is over all His works.
The world goes up and the world goes down, the sunshine follows the rain; and yesterday's sneer and yesterday's frown can never come over again.
