Undertake not to teach your equal in the art himself professes; it savors arrogancy.

In praise there is more obtrusiveness than in blame.

Undeserved praise causes more pangs of conscience later than undeserved blame, but probably only for this reason, that our power of judgment are more completely exposed by being over praised than by being unjustly underestimated.

This is the hardest of all: to close the open hand out of love, and keep modest as a giver.

We praise or blame as one or the other affords more opportunity for exhibiting our power of judgement.

What can everyone do? Praise and blame. This is human virtue, this is human madness.
