Now that we have ascertained what is just and what is unjust, we may say that a man acts unjustly or justly when he does these things voluntarily; but when he does them involuntarily, he does not, strictly speaking, act either unjustly or justly, but only “accidentally,” i.e. he does a thing which happens to be just or unjust. 127 For whether an act is or is not to be called an act of injustice (or of justice) depends upon whether it is voluntary or involuntary; for if it be voluntary the agent is blamed, and at the same time the act becomes an act of injustice: so something unjust may be done, and yet it may not be an act of injustice, i.e. if this condition of voluntariness be absent.
