Cowards die many times before their deaths. The valiant never taste of death but once. Of all the wonders that I yet have heard, It seems to me most strange that men should fear, Seeing that death, a necessary end, Will come when it will come.

Which offers the best summary of the central idea of Caesar's speech?

Most fear the unpredictability of death.
Living in fear is the same as dying.
Man can only die once in his lifetime.
Death is final and necessary for cowards.
