And knowledge, but from hour to hour

In reverence and in charity.

Tennyson.

Knowledge holdeth by the hilt, and heweth out a road to conquest;

Ignorance graspeth the blade, and is wounded by its own good sword.

Knowledge distilleth health from the virulence of opposite poisons;

Ignorance mixeth wholesomes unto the breeding of disease.

Knowledge is leagued with the universe, and findeth a friend in all things;

But ignorance is everywhere a stranger, unwelcome, ill at ease, and out of place.

M. F. Tupper.
