Ignorance breeds monsters to fill up the vacancies of the soul that are unoccupied by the verities of knowledge.

The most formidable attribute of temptation is its increasing power, its accelerating ratio of velocity. Every act of repetition increases power, diminishes resistance. It is like the letting out of waters-where a drop can go, a river can go. Whoever yields to temptation, subjects himself to the law of falling bodies.

Bodies are cleansed by water; the mind is purified by truth.

The soul of the truly benevolent man does not seem to reside much in his own body. Its life, to a great extent, is a mere reflex of the lives of others. It migrates into their bodies, and identifying its existence with their existence, finds its own happiness in increasing and prolonging their pleasures, in extinguishing or solacing their pains.

Teaching isn't one-tenth as effective as training.

Avoid witticisms at the expense of others.

A teacher should, above all things, first induce a desire in the pupil for the acquisition he wishes to impart.
