What is an example of a soliloquy in "Julius Caesar?"

One example of a soliloquy in William Shakespeare's play "Julius Caesar" is found in Act II Scene 1 in lines 10 through 34. It is delivered by the character Brutus, one of the key conspirators in Caesar's death.

Brutus is alone in his orchard. He reveals that he knows Caesar must die. It is obvious that Caesar is to be crowned king, and Brutus believes that receiving this power is likely to change Caesar for the worse.

In his speech, Brutus speaks of how, once a person has climbed a ladder, he often turns against those he has passed while climbing. At the end of the soliloquy, Brutus concludes that the prospect of Caesar's rise to power is a danger that must be averted by his death.
