There are _three degrees of proficients_ in the school of wisdom. The _first_ are those that come within sight of it, but not up to it—they have learned what they ought to do, but they have not put their knowledge in practice—they are past the hazard of a relapse, but they have still the grudges of a disease, though they are out of the danger of it. By a disease I do understand an obstinacy in evil, or an ill habit, that makes us over eager upon things which are either not much to be desired, or not at all. A _second_ sort are those that have subjected their appetites for a season, but are yet in fear of falling back. A _third_ sort are those that are clear of many vices but not of all. They are not covetous, but perhaps they are choleric—nor lustful, but perchance ambitious; they are firm enough in some cases but weak enough in others: there are many that despise death and yet shrink at pain. There are diversities in wise men, but no inequalities—one is more affable, another more ready, a third a better speaker; but the felicity of them all is equal. It is in this as in heavenly bodies, there is a _certain state_ in greatness.
