Again, accidentality may attach to the unjust in like manner as to the just acts. For instance, a man may have restored what was deposited with him, but against his will and from fear of the consequences of a refusal: we must not say that he either does what is just, or does justly, except accidentally: and in like manner the man who through compulsion and against his will fails to restore a deposit, must be said to do unjustly, or to do what is unjust, accidentally only.
Again, voluntary actions we do either from deliberate choice or without it; from it, when we act from previous deliberation; without it, when without any previous deliberation. Since then hurts which may be done in transactions between man and man are threefold, those mistakes which are attended with ignorance are, when a man either does a thing not to the man to whom he meant to do it, or not the thing he meant to do, or not with the instrument, or not with the result which he intended: either he did not think he should hit him at all, or not with this, or this is not the man he thought he should hit, or he did not think this would be the result of the blow but a result has followed which he did not anticipate; as, for instance, he did it not to wound but merely to prick him; or it is not the man whom, or the way in which, he meant.

When again he acts with knowledge, but not from previous deliberation, it is an unjust action; for instance, whatever happens to men from anger or other passions which are necessary or natural: for when doing
