Genius is the father of a heavenly line, but the mortal mother, that is industry.

In all the world there is nothing so remarkable as a great man, nothing so rare, nothing which so well repays study.

The most useful is the greatest.

Love of truth will bless the lover all his days; yet when he brings her home, his fair-faced bride, she comes empty-handed to his door, herself her only dower.

I do not pretend to understand the moral universe; the arc is a long one, my eye reaches but little ways; I cannot calculate the curve and complete the figure by the experience of sight, I can divine it by conscience. And from what I see I am sure it bends towards justice.

Justice is the idea of God, the ideal of man, the rule of conduct writ in the nature of mankind.

Nature is God's Old Testament.
