Well, sickness is excess or defect in the body, which as a material organism rebels against order and measure; ugliness is but matter not mastered by Ideal-Form; poverty consists in our need and lack of goods made necessary to us by our association with Matter whose very nature is to be one long want.
If all this be true, we cannot be, ourselves, the source of Evil, we are not evil in ourselves; Evil was before we came to be; the Evil which holds men down binds them against their will; and for those that have the strength — not found in all men, it is true — there is a deliverance from the evils that have found lodgement in the soul.
In a word since Matter belongs only to the sensible world, vice in men is not the Absolute Evil; not all men are vicious; some overcome vice, some, the better sort, are never attacked by it; and those who master it win by means of that in them which is not material.
