“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.”

“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.”

“Into what dangers would you lead me, Cassius,That you would have me seek into myselfFor that which is not in me?”

“The fringed curtains of thine eye advance,And say what thou seest yond.”

“No, Cassius; for the eye sees not itself,But by reflection, by some other things.”

“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.”
