But in ourselves, that we are underlings."
These lines are from Act 1, Scene 2 of Shakespeare's play "Julius Caesar," spoken by Cassius to Brutus. In this context, Cassius is trying to convince Brutus that the reason he feels compelled to join the conspiracy to assassinate Julius Caesar is not due to fate or destiny, but rather due to the weakness and complacency of the conspirators themselves. He is essentially saying that they should not blame external forces for their actions, but rather take responsibility for their own choices and decisions.
