The proper study of mankind is books.
Aldous Huxley

The sacred rights of mankind are not to be rummaged for among old parchments or musty records. They are written, as with a sunbeam, in the whole volume of human nature, by the hand of the divinity itself; and can never be erased.
Alexander Hamilton

National character is only another name for the particular form which the littleness, perversity and baseness of mankind take in every country. Every nation mocks at other nations, and all are right.
Arthur Schopenhauer

The doctor sees all the weakness of mankind; the lawyer all the wickedness, the theologian all the stupidity.
Arthur Schopenhauer

I think you can leave the arts, superior or inferior, to the conscience of mankind.
William Butler Yeats

The idea of God is the sole wrong for which I cannot forgive mankind.
Marquis de Sade

We are justified in enforcing good morals, for they belong to all mankind; but we are not justified in enforcing good manners, for good manners always mean our own manners.
Gilbert K. Chesterton

For the first time in the history of mankind, one generation literally has the power to destroy the past, the present and the future, the power to bring time to an end.
Hubert H. Humphrey

Mankind is like dogs, not gods - as long as you don't get mad they'll bite you - but stay mad and you'll never be bitten. Dogs don't respect humility and sorrow.
Jack Kerouac

All human beings are also dream beings. Dreaming ties all mankind together.
Jack Kerouac

The most costly of all follies is to believe passionately in the palpably not true. It is the chief occupation of mankind.
H. L. Mencken

All ambitions are lawful except those that climb upward on the miseries or credulities of mankind.
Henry Ward Beecher

A physician is not angry at the intemperance of a mad patient, nor does he take it ill to be railed at by a man in fever. Just so should a wise man treat all mankind, as a physician does his patient, and look upon them only as sick and extravagant.
Lucius Annaeus Seneca

A large part of mankind is angry not with the sins, but with the sinners.
Lucius Annaeus Seneca

I love mankind; it's people I can't stand.
Charles M. Schulz

Mankind must remember that peace is not God's gift to his creatures; peace is our gift to each other.
Elie Wiesel

Mankind is not a circle with a single center but an ellipse with two focal points of which facts are one and ideas the other.
Victor Hugo

The proper study of Mankind is Man.
Alexander Pope

Know then thyself, presume not God to scan; The proper study of mankind is man.
Alexander Pope

I find myself hoping a total end of all the unhappy divisions of mankind by party-spirit, which at best is but the madness of many for the gain of a few.
Alexander Pope
