SOCRATES: But I imagined, Hippias, that you did. Please to answer once
more: Is not justice a power, or knowledge, or both? Must not justice, at
all events, be one of these?

HIPPIAS: Yes.

SOCRATES: But if justice is a power of the soul, then the soul which has
the greater power is also the more just; for that which has the greater
power, my good friend, has been proved by us to be the better.

HIPPIAS: Yes, that has been proved.

SOCRATES: And if justice is knowledge, then the wiser will be the juster
soul, and the more ignorant the more unjust?

HIPPIAS: Yes.

SOCRATES: But if justice be power as well as knowledge--then will not the
soul which has both knowledge and power be the more just, and that which is
the more ignorant be the more unjust? Must it not be so?

HIPPIAS: Clearly.

SOCRATES: And is not the soul which has the greater power and wisdom also
better, and better able to do both good and evil in every action?

HIPPIAS: Certainly.

SOCRATES: The soul, then, which acts ill, acts voluntarily by power and
art--and these either one or both of them are elements of justice?
