"For a base person, if led into better ways of living and speaking, may show some improvement, even if only a little bit, toward being a better person. But if he should once improve a little, it is evident that he might change completely or improve a great deal; for even if he improves just a little from his starting-point, he keeps getting more inclined toward virtue, so that he is likely to improve even more. And if this keeps happening, he will be restored completely to the contrary state—if time is not exhausted." Aristotle,categories
