One lives but once in the world.

The important thing is not to know more than all men, but to know more at each moment than any particular man.

No two men see the world exactly alike, and different temperaments will apply in different ways a principle that they both acknowledge. The same man will, indeed, often see and judge the same things differently on different occasions: early convictions must give way to more mature ones. Nevertheless, may not the opinions that a man holds and expresses withstand all trials, if he only remains true to himself and others?

Love can do much, but duty more.

Mastery is often taken for egotism.

Deeply earnest and thoughtful people stand on shaky footing with the public.
