Let us recognize the beauty and power of true enthusiasm; and whatever we may do to enlighten ourselves and others, guard against checking or chilling a single earnest sentiment.—Tuckerman.

Nothing is so contagious as enthusiasm; it moves stones, it charms brutes. Enthusiasm is the genius of sincerity, and truth accomplishes no victories without it.—Lytton.

Every great and commanding movement in the annals of the world is the triumph of enthusiasm.—Emerson.

The most enthusiastic man in a cause is rarely chosen as a leader.—Arthur Helps.

Let us beware of losing our enthusiasms. Let us ever glory in something, and strive to retain our admiration for all that would ennoble, and our interest in all that would enrich and beautify our life.—Phillips Brooks.

Envy.—There is not a passion so strongly rooted in the human heart as envy.—Sheridan.

An envious man waxeth lean with the fatness of his neighbors. Envy is the daughter of pride, the author of murder and revenge, the beginner of secret sedition and the perpetual tormentor of virtue. Envy is the filthy slime of the soul; a venom, a poison, or quicksilver which consumeth the flesh and drieth up the marrow of the bones.—Socrates.

As a moth gnaws a garment, so doth envy consume a man.—St. Chrysostom.

We ought to be guarded against every appearance of envy, as a passion that always implies inferiority wherever it resides.—Pliny.

Base envy withers at another's joy,
And hates that excellence it cannot reach.
—Thomson.
