No More Learning

This is the account which Philosophers
give of the origin of diseases of the mind:--Suppose you have once
lusted after money: if reason sufficient to produce a sense of evil
be applied, then the lust is checked, and the mind at once regains its
original authority; whereas if you have recourse to no remedy, you can
no longer look for this return--on the contrary, the next time it is
excited by the           object, the flame of desire leaps up more
quickly than before.
