A nitpicky note: Aeschylus didn't say that.

RFK probably studied Aeschylus in the original Greek, and did an on-the-fly translation. A more literal translation is:

"Zeus, who guided men to think, who has laid it down that wisdom comes alone through suffering. Still there drips in sleep against the heart grief of memory; against our will temperance comes. From the gods who sit in grandeur grace is somehow violent."

There's no "turning the other cheek here." It claims violence does indeed beget violence, and there's no human way around that.

To be clear, I'm not advocating violence, or even criticizing RFK. I'm simply defending the purity of Aeschylus.
