For of all creatures that breathe and creep about on the earth, there is none so miserable as man.

Men are very much to be pitied in that they are to be governed by a king who is but a man like them; for it would require Gods to reform men. But kings are not less to be pitied, since being but men, that are weak and imperfect, they are to govern this innumerable multitude of corrupt and deceitful men.

Nobody can hate man more than man.

Experience has taught me, in fact, that no man should be pitied because, every day in his life, he faces a hard, stubborn problem, but rather that it is the man who has no problem to solve, no hardships to face, who is to be pitied.

It is just like man's vanity and impertinence to call an animal dumb because it is dumb to his dull perceptions. Heaven is by favor; if it were by merit your dog would go in and you would stay out. Of all the creatures ever made he (man) is the most detestable. Of the entire brood, he is the only one...that possesses malice. He is the only creature that inflicts pain for sport, knowing it to be pain. The fact that man knows right from wrong proves his intellectual superiority to the other creatures; but the fact that he can do wrong proves his moral inferiority to any creature that cannot.

There is nothing alive more agonized than man / of all that breathe and crawl across the earth.

Among all creatures that breathe on earth and crawl on it
there is not anywhere a thing more dismal than man is.

Of all that breathes and crawls across the earth,
our mother earth breeds nothing feebler than a man.

294. A man's discontent is his worst evill.

Man, I can assure you, is a nasty creature.

If there is one person I do despise more than another, it is the man who does not think exactly the same on all topics as I do...

What was it in the human heart that made you despise a man because he loved you?

A man is a poor creature compared to a woman.

There's no creature on earth so despicable and loathsome as a rich man with a conscience.
