“I do not know the man I should avoid So soon as that spare Cassius. He reads much, He is a great observer, and he looks Quite through the deeds of men. He loves no plays As thou dost, Anthony; he heard no music; Seldom he smiles, and smiles in such a sort As if he mocked himself and scorned his spirit That could be moved to smile at anything. Such men as he be never at heart's ease Whiles they behold a greater than themselves, And therefore are they very dangerous.”

“He reads much;He is a great observer and he looksQuite through the deeds of men: he loves no plays,As thou dost, Antony; he hears no music;Seldom he smiles, and smiles in such a sortAs if he mock'd himself and scorn'd his spiritThat could be moved to smile at any thing.Such men as he be never at heart's easeWhiles they behold a greater than themselves,And therefore are they very dangerous.”

“Yond Cassius has a lean and hungry look;He thinks too much: such men are dangerous”

“Let me have men about me that are fat,...Sleek-headed men and such as sleep a-nights.Yond Cassius has a lean and hungry look,He thinks too much; such men are dangerous.”

“God made him, and therefore let him pass for a man. In truth, I know it is a sin to be a mocker, but he! why, he hath a horse better than the Neapolitan’s, a better bad habit of frowning than the Count Palentine; he is every man in no man. If a throstle sing, he falls straight a-cap’ring. He will fence with his own shadow. If I should marry him, I should marry twenty husbands.”

“Cannot you tell that? Every fool can tell that. It was the very day that young Hamlet was born, he that is mad and sent into England.""Ay, marry, why was he sent into England?""Why, because he was mad. He shall recover his wits there, or, if he do not, it's no great matter there.""Why?""'Twill not be seen in him there. There the men are as mad as he.”

“This fellow is wise enough to play the fool;And to do that well craves a kind of wit:He must observe their mood on whom he jests,The quality of persons, and the time,And, like the haggard, check at every featherThat comes before his eye. This is a practiseAs full of labour as a wise man's artFor folly that he wisely shows is fit;But wise men, folly-fall'n, quite taint their wit.”
