Well: human Excellence is of two kinds, Intellectual and Moral:[1] now the Intellectual springs originally, and is increased subsequently, from teaching (for the most part that is)[2], and needs therefore experience and time; whereas the Moral comes from custom, and so the Greek term denoting it is but a slight deflection from the term denoting custom in that language.
From this fact it is plain that not one of the Moral Virtues comes to be in us merely by nature: because of such things as exist by nature, none can be changed by custom: a stone, for instance, by nature gravitating downwards, could never by custom be brought to ascend, not even if one were to try and accustom it by throwing it up ten thousand times; nor could fire again be brought to descend, nor in fact could anything whose nature is in one way be brought by custom to be in another. The Virtues then come to be in us neither by nature, nor in despite of nature, but we are furnished by nature with a capacity for receiving them,[3] and are perfected in them through custom.
Again, in whatever cases we get things by nature, we get the faculties first and perform the acts of working afterwards; an illustration of which is afforded by the case of our bodily senses, for it was not from having often seen or heard that we got these senses, but just the reverse: we had them and so exercised them, but did not have them because we had exercised them. But the Virtues we get by first performing single acts of working, which, again, is the case of other things, as the arts for instance; for what we have to make when we have learned how, these we learn how to make by making: men come to be builders, for instance, by building;
