3 And to effect this Aristotle and Theophrastus recommend the softening of harsh metaphors by the use of some such phrase as “So to say,” “As it were,” “If I may be permitted the expression,” “If so bold a term is allowable.” For thus to forestall criticism[3] mitigates, they assert, the boldness of the metaphors.
4 And I will not deny that these have their use. Nevertheless I must repeat the remark which I made in the case of figures,[4] and maintain that there are native antidotes to the number and boldness of metaphors, in well-timed displays of strong feeling, and in unaffected sublimity, because these have an innate power by the dash of their movement of sweeping along and carrying all else before them. Or should we not rather say that they absolutely demand as indispensable the use of daring metaphors, and will not allow the hearer to pause and criticise the number of them, because he shares the passion of the speaker?
5 In the treatment, again, of familiar topics and in descriptive passages nothing gives such distinctness as a close and continuous series of metaphors. It is by this means that Xenophon has so finely delineated the anatomy of the human frame.[5] And there is a still more brilliant and life-like picture in Plato.[6] The human head he calls a _citadel_; the neck is an _isthmus_ set to divide it from the chest; to support it beneath are the vertebrae, turning like _hinges_; pleasure he describes as a _bait_ to tempt men to ill; the tongue is the _arbiter of tastes_. The heart is at once the _knot_ of the veins and the _source_ of the rapidly circulating blood, and is stationed in the _guard-room_ of the body. The ramifying blood-vessels he calls _alleys_. “And casting about,” he says, “for something to sustain the violent palpitation of the heart when it is alarmed by the approach of danger or agitated by passion, since at such times it is overheated, they (the gods) implanted in us the lungs, which are so fashioned that being soft and bloodless, and having cavities within, they act like a buffer, and when the heart boils with inward passion by yielding to its throbbing save it from injury.” He compares the seat of the desires to the _women’s quarters_, the seat of the passions to the _men’s quarters_, in a house. The spleen, again, is the _napkin_ of the internal organs, by whose excretions it is saturated from time to time, and swells to a great size with inward impurity. “After this,” he continues, “they shrouded the whole with flesh, throwing it forward, like a cushion, as a barrier against injuries from without.” The blood he terms the _pasture_ of the flesh. “To assist the process of nutrition,” he goes on, “they divided the body into ducts, cutting trenches like those in a garden, so that, the body being a system of narrow conduits, the current of the veins might flow as from a perennial fountain-head. And when the end is at hand,” he says, “the soul is cast loose from her moorings like a ship, and free to wander whither she will.”
