Knowing is not enough; we must apply. Willing is not enough; we must do.

What then is your duty? What the day demands.

All our knowledge is symbolic.

The happiest man is the one who finds happiness at home.

The intelligent man finds almost everything ridiculous, the sensible man hardly anything.

So dear night the half of life is, And the fairest half indeed.

The day is committed to error and floundering; success and achievement are matters of long range.
