But does the soul admit of degrees? or is one soul in the very least degree more or less, or more or less completely, a soul than another?
Not in the least.
Yet surely of two souls, one is said to have intelligence and virtue, and to be good, and the other to have folly and vice, and to be an evil soul: and this is said truly?
Yes, truly.
But what will those who maintain the soul to be a harmony say of this presence of virtue and vice in the soul?—will they say that here is another harmony, and another discord, and that the virtuous soul is harmonized, and herself being a harmony has another harmony within her, and that the vicious soul is inharmonical and has no harmony within her?
I cannot tell, replied Simmias; but I suppose that something of the sort would be asserted by those who say that the soul is a harmony.
And we have already admitted that no soul is more a soul than another; which is equivalent to admitting that harmony is not more or less harmony, or more or less completely a harmony?
Quite true.
And that which is not more or less a harmony is not more or less harmonized?
True.
And that which is not more or less harmonized cannot have more or less of harmony, but only an equal harmony?
Yes, an equal harmony.
Then one soul not being more or less absolutely a soul than another, is not more or less harmonized?
Exactly.
And therefore has neither more nor less of discord, nor yet of harmony?
She has not.
And having neither more nor less of harmony or of discord, one soul has no more vice or virtue than another, if vice be discord and virtue harmony?
Not at all more.
Or speaking more correctly, Simmias, the soul, if she is a harmony, will never have any vice; because a harmony, being absolutely a harmony, has no part in the inharmonical.
No.
And therefore a soul which is absolutely a soul has no vice?
How can she have, if the previous argument holds?
Then, if all souls are equally by their nature souls, all souls of all living creatures will be equally good?
I agree with you, Socrates, he said.
And can all this be true, think you? he said; for these are the consequences which seem to follow from the assumption that the soul is a harmony?
