There is nothing more foolish, nothing more given to outrage than a useless mob.

Knowledge may give weight, but accomplishments give lustre, and many more people see than weigh.

It is better, of course, to know useless things than to know nothing.

Nothing is so contemptible as the sentiments of the mob.

Of all men's miseries the bitterest is this: to know so much and to have control over nothing.

The ears of men are lesser agents of belief than their eyes.
