A just thinker will allow full swing to his scepticism. I dip my pen in the blackest ink, because I am not afraid of falling into my inkpot.... We are of different opinions at different hours, but we always may be said to be at heart on the side of truth.
There is a relation between the hours of our life and the centuries of time. As the air I breathe is drawn from the great repositories of nature, as the light on my book is yielded by a star a hundred millions of miles distant, as the poise of my body depends on the equilibrium of centrifugal and centripetal forces, so the hours should be instructed by the ages and the ages explained by the hours.
The intellectual life may be kept clean and healthful, if man will live the life of nature, and not import into his mind difficulties which are none of his.
Guard well your spare moments. They are like uncut diamonds. Discard them and their value will never be known. Improve them and they will become the brightest gems in a useful life.
Sleep takes off the costume of circumstance, arms us with terrible freedom, so that every will rushes to deed. A skillful man reads his dreams for his self-knowledge; yet not the details, but the quality. What part does he play in them - a cheerful, manly part, or a poor, drivelling part? However monstrous and grotesque their apparitions, they have a substantial truth.
Converse with a mind that is grandly simple, and literature looks like word-catching. The simplest utterances are worthiest to bewritten, yet are they so cheap, and so things of course, that, in the infinite riches of the soul, it is like gathering a few pebbles off the ground, or bottling a little air in a phial, when the whole earth and the whole atmosphere are ours.
Numbers serve to discipline rhetoric. Without them it is too easy to follow flights of fancy, to ignore the world as it is and to remold it nearer the heart's desire.
