But if no one approves of this, and if on the contrary we all of us foresee that the more we allow him to extend his power, the stronger and more formidable we shall find him in war, what escape is open to us, or why do we delay? When, men of Athens, shall we consent to do our duty? Whenever it is necessary, you will say.

But what any free man would call necessity is not merely present now, but is long ago past, and from the necessity that constrains a slave we must surely pray to be delivered. Do you ask the difference? The strongest necessity that a free man feels is shame for his own position, and I know not if we could name a stronger; but for a slave necessity means stripes and bodily outrage, unfit to name here, from which Heaven defend us!
