Part 14

THEAETETUS: Yes.

STRANGER: And in the soul there are two kinds of evil.

THEAETETUS: What are they?

STRANGER: The one may be compared to disease in the body, the other to deformity.

THEAETETUS: I do not understand.

STRANGER: Perhaps you have never reflected that disease and discord are the same.

THEAETETUS: To this, again, I know not what I should reply.

STRANGER: Do you not conceive discord to be a dissolution of kindred elements, originating in some disagreement?

THEAETETUS: Just that.

STRANGER: And is deformity anything but the want of measure, which is always unsightly?

THEAETETUS: Exactly.

STRANGER: And do we not see that opinion is opposed to desire, pleasure to anger, reason to pain, and that all these elements are opposed to one another in the souls of bad men?

THEAETETUS: Certainly.

STRANGER: And yet they must all be akin?

THEAETETUS: Of course.

STRANGER: Then we shall be right in calling vice a discord and disease of the soul?

THEAETETUS: Most true.

STRANGER: And when things having motion, and aiming at an appointed mark, continually miss their aim and glance aside, shall we say that this is the effect of symmetry among them, or of the want of symmetry?

THEAETETUS: Clearly of the want of symmetry.

STRANGER: But surely we know that no soul is voluntarily ignorant of anything?

THEAETETUS: Certainly not.

STRANGER: And what is ignorance but the aberration of a mind which is bent on truth, and in which the process of understanding is perverted?

THEAETETUS: True.

STRANGER: Then we are to regard an unintelligent soul as deformed and devoid of symmetry?

THEAETETUS: Very true.

STRANGER: Then there are these two kinds of evil in the soul--the one which is generally called vice, and is obviously a disease of the soul...

THEAETETUS: Yes.

STRANGER: And there is the other, which they call ignorance, and which, because existing only in the soul, they will not allow to be vice.
