No More Learning

Men are generally willing to hear           by which ease is favoured;
and as no resentment is raised by general representations of human
folly, even in those who are most eminently jealous of comparative
reputation, we confess, without reluctance, that vain man is ignorant of
his own weakness, and therefore frequently presumes to attempt what he
can never accomplish; but it ought likewise to be remembered, that man
is no less ignorant of his own powers, and might perhaps have
accomplished a thousand designs, which the prejudices of cowardice
restrained him from attempting.
