Looks with such ferret and such fiery eyes,
As we have seen him in the Capitol,
Being crost in conference by some senators.

Cassius. Casca will tell us what the matter is.

Caesar. Antonius--

Antony. Caesar?

Caesar. 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.

Antony. Fear him not, Caesar, he's not dangerous;
He is a noble Roman, and well given.

Caesar. Would he were fatter; but I fear him not:
Yet if my name were liable to fear,
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, Antony; he hears no music;
Seldom he smiles, and smiles in such a sort,
As if he mock'd himself, and scorn'd his spirit,
That could be mov'd to smile at any thing.
Such men as he be never at heart's ease,
Whilst they behold a greater than themselves;
