Read the excerpt from act 1, scene 3, of Julius Caesar . [CASSIUS.] Cassius from bondage will deliver Cassius. Therein, ye gods, you make the weak most strong; Therein, ye gods, you tyrants do defeat. Nor stony tower, nor walls of beaten brass, Nor airless dungeon, nor strong links of iron, Can be retentive to the strength of spirit; But life, being weary of these worldly bars, Never lacks power to dismiss itself. If I know this, know all the world besides, That part of tyranny that I do bear I can shake off at pleasure. [Thunder still] CASCA: So can I. So every bondman in his own hand bears The power to cancel his captivity. How does Cassius's proclamation affect Casca?
