The doctrine, in its very earliest form, had left a large neutral ground between good and evil, comprehending almost all the common objects of desire and avoidance. These the Stoics now proceeded to divide according to a similar principle of arrangement. Whatever, without being morally good in the strictest sense, was either conducive to morality, or conformable to human nature, or both, they called preferable. Under this head came personal advantages, such as mental accomplishments, beauty, health, strength, and life itself; together with external advantages, such as wealth, honour, and high connexions. The opposite to preferable things they called objectionable; and what lay between the two, such as the particular coin selected to make a payment with, absolutely indifferent.[58] The thorough-going condemnation of passion was explained away to a certain extent by allowing the sage himself to feel a slight touch of the feelings which fail to shake his determination, like a scar remaining after the wound is healed; and by admitting the desirability of sundry emotions, which, though carefully distinguished from the passions, seem to have differed from them in degree rather than in kind.[59] In like manner, the peremptory alternative between consummate wisdom and utter folly was softened down by admitting the possibility of a gradual progress from one to the other, itself subdivided into a number of more or less advanced grades, recalling Aristotle’s idea of motion as a link between Privation and Form.[60] If there be a class of persons who although not perfectly virtuous are on the road to virtue, it follows that there are moral actions which they are capable of performing. These the Stoics called intermediate or imperfect duties; and, in accordance with their intellectual view of conduct, they defined them as actions for which a probable reason might be given; apparently in contradistinction to those which were deduced from a single principle with the extreme rigour of scientific demonstration. Such intermediate duties would have for their appropriate object the ends which, without being absolutely good, were still relatively worth seeking, or the avoidance of what, without being an absolute evil, was allowed to be relatively objectionable. They stood midway between virtue and vice, just as the progressive characters stood between the wise and the foolish, and preferable objects between what was really good and what was really evil.
