Putting yourself out of business

The proper aim of giving is to put the recipient in a state where he no longer needs our gift. We feed children in order that they soon be able to feed themselves; we teach them in order that they may soon not need our teaching. The hour when we can say “They need me no longer” should be our reward.

My own profession – that of a university teacher – is in this way dangerous. If we are any good we must always be working towards the moment at which our pupils are fit to become our critics and rivals. We should be delighted when it arrives, as the fencing master is delighted when his pupil can pink and disarm him. Any many are. But not all.
