But since the unequal and the unlawful are not the same, but are different as a part is from its whole (for all that is unequal is unlawful, but not all that is unlawful is unequal), the unjust and injustice are not the same as but different from the former kind, as part from whole; for injustice in this sense is a part of injustice in the wide sense, and similarly justice in the one sense of justice in the other.
