Again, one may go wrong in many different ways (because, as the Pythagoreans expressed it, evil is of the class of the infinite, good of the finite), but right only in one; and so the former is easy, the latter difficult; easy to miss the mark, but hard to hit it: and for these reasons, therefore, both the excess and defect belong to Vice, and the mean state to Virtue; for, as the poet has it,
“Men may be bad in many ways,
But good in one alone.”
Chapter VI.
Virtue then is “a state apt to exercise deliberate choice, being in the relative mean, determined by reason, and59 as the man of practical wisdom would determine.”
It is a middle state between too faulty ones, in the way of excess on one side and of defect on the other: and it is so moreover, because the faulty states on one side fall short of, and those on the other exceed, what is right, both in the case of the feelings and the actions; but Virtue finds, and when found adopts, the mean.
And so, viewing it in respect of its essence and definition, Virtue is a mean state; but in reference to the chief good and to excellence it is the highest state possible.
But it must not be supposed that every action or every feeling is capable of subsisting in this mean state, because some there are which are so named as immediately to convey the notion of badness, as malevolence, shamelessness, envy; or, to instance in actions, adultery, theft, homicide; for all these and suchlike are blamed because they are in themselves bad, not the having too much or too little of them.
