Instruction does much, but encouragement everything."

(Letter to A.F. Oeser, Nov. 9, 1768)

Correction does much, but encouragement does more.

Correction does much, but encouragement does more. Encouragement after censure is as the sun after a shower.

In the end we retain from our studies only that which we practically apply.

The intelligent man finds almost everything ridiculous, the sensible man almost nothing.

They teach in academies far too many things, and far too much that is useless.
