From whence we must conceive that these virtues follow (each other) in turn. For as Fortitude is preservative of a lawful dogma, so it is of right reason. ... Now no one is able to see what is good, while it is rendered obscure by cowardice, and the feelings that follow upon cowardice. And nearly in the same manner a person is unable to act with prudence in union with intemperance, or generally through being subdued by any feeling. ... The perfect virtues therefore are thus inseparable from each other. ... And we must consider that some Virtues lead and others follow; and that the leaders are those, which are in the (portion), influenced by reason, from whom the rest obtain their perfection; but the followers are those in the portion affected by suffering; for these work out what is right, not according to the reason that is in them—for they have it not—but according to that, which is bestowed upon them by Prudence, (and) generated by custom and practice. ... Prudence however, as being a science, imparts to each (subordinate virtue) its own peculiarity, just as the pilot gives to the sailors certain orders, not contemplated by them, and they obey him. — Alcinous, *Handbook of Platonism*, Chs. 28–29, trans. George Burges (1854), pp. 300–303. *Surface Gloss:* Perfect virtues are mutually inseparable: you cannot be prudent while cowardly or intemperate, nor truly brave without prudence. Yet within the soul, rational Prudence is the only true science; the passionate virtues cannot be taught, obeying Prudence like sailors following a pilot's uncomprehended orders. **The Pilot-and-Deckhand Architecture (Mutual Lock + Asymmetric Comprehension):** High-level competence is an all-or-nothing circuit: your strategic clarity (Prudence) is only as good as your nerve under fire (Fortitude) and your impulse control (Temperance)—if one breaks, it blinds the others. Yet your lower habits don't need to "understand" the strategy; they just need to be drilled until they obey the pilot's call on contact.
