Knowledge is

Bought only with a weary care,
And wisdom means a world of pain. 

                                    —­Joaquin Miller.

The knowledge which we have acquired ought not to resemble a great shop without order, and without an inventory; we ought to know what we possess, and be able to make it serve us in need.—­Leibnitz.

Knowledge is power as well as fame.—­Rufus Choate.

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.—­Tupper.

A Persian philosopher, being asked by what method he had acquired so much knowledge, answered, “By not being prevented by shame from asking questions where I was ignorant.”

Every human being whose mind is not debauched, will be willing to give all that he has to get knowledge.—­Dr. Johnson.

That learning which thou gettest by thy own observation and experience, is far beyond that which thou gettest by precept; as the knowledge of a traveler exceeds that which is got by reading.—­Thomas A kempis.

If you have knowledge, let others light their candles at it.—­Fuller.

Knowledge will not be acquired without pains and application.  It is troublesome and deep, digging for pure waters; but when once you come to the spring, they rise up and meet you.—­Felton.

Knowledge is proud that he has learned so much; Wisdom is humble that he knows no more.—­Cowper.

All wish to possess knowledge, but few, comparatively speaking, are willing to pay the price.—­Juvenal.

Seldom ever was any knowledge given to keep, but to impart; the grace of this rich jewel is lost in concealment.—­Bishop Hall.

There is no knowledge for which so great a price is paid as a knowledge of the world; and no one ever became an adept in it except at the expense of a hardened or a wounded heart.—­Lady BLESSINGTON.

The sure foundations of the State are laid in knowledge, not in ignorance; and every sneer at education, at culture, at book learning, which is the recorded wisdom of the experience of mankind, is the demagogue’s sneer at intelligent liberty, inviting national degeneracy and ruin.—­G.W.  Curtis.

Labor.—­Labor is one of the great elements of society,—­the great substantial interest on which we all stand.—­Daniel Webster.

Hard workers are usually honest.  Industry lifts them above temptation.  —­Bovee.

Bodily labor alleviates the pains of the mind; and hence arises the happiness of the poor.—­La ROCHEFOUCAULD.

Labor disgraces no man; unfortunately, you occasionally find men who disgrace labor.—­U.S.  Grant.

If the power to do hard work is not talent, it is the best possible substitute for it.—­James A. Garfield.
