Chapter 60 · Breathing and bodily processes
I.60.heading · Wachsmuth pp. 499
On breathing and bodily processes.2066
1.1 · Breathing in a world without a void
I.60.1.1 · Wachsmuth pp. 499-500
Plato, from the Timaeus.
“Let us return to the process of breathing and consider the causes through which it has come to be as it now is. The account is this. Since there is no void into which any moving thing could enter, yet breath moves outward from us, what follows is already clear to everyone: it does not pass into a void, but pushes what is next to it out of its place.”2067
1.2 · A circuit of displacement
I.60.1.2 · Wachsmuth pp. 500
“What is pushed always drives out its neighbor in turn. Under this very necessity, the whole mass is driven around into the place from which the breath departed; entering there and filling it again, it follows the breath. All this happens together, as though a wheel were turning, because there is no void.”2068
1.3 · Refilling the chest and lung
I.60.1.3 · Wachsmuth pp. 500
“Thus the region of the chest and lung, having let the breath out, is filled again by the air around the body, which penetrates inward through the porous parts of the flesh and is driven around.”2069
1.4 · The return movement of air
I.60.1.4 · Wachsmuth pp. 500
“Then, turning back and passing through the body from outside, the air drives the breath inward through the passage of the mouth and the nostrils.”2070
1.5 · The source of bodily heat
I.60.1.5 · Wachsmuth pp. 500
“We must give the following cause of their beginning. Every animal has its hottest parts within itself, around the blood and the vessels, as though there were a spring of fire inside it.”2071
1.6 · The mesh of fire and air
I.60.1.6 · Wachsmuth pp. 500
“We also liken this to the mesh of a fish trap: what is stretched through the middle is woven wholly of fire, while the other parts, outside, are of air. We must agree that what is hot naturally travels outward to its own region, toward what is akin to it.”2072
1.7 · Two outlets
I.60.1.7 · Wachsmuth pp. 500
“There are two outlets, one outward through the body, the other through the mouth and nostrils. Whenever the heat rushes toward one, it drives the air around by the other. What is driven around falls into the fire and is heated; what goes out is cooled.”2073
1.8 · Alternating inhalation and exhalation
I.60.1.8 · Wachsmuth pp. 500-501
“When the heat shifts and what lies by the other outlet grows hotter, the hotter part leans more in that direction in turn, moving toward its own nature, and drives around what lies by the opposite route. This continually undergoes the same effects and returns them in kind, producing a circle that is always being rocked to and fro by both movements, and so brings about inhalation and exhalation.”2074
1.9 · Cupping, drinking, and moving bodies
I.60.1.9 · Wachsmuth pp. 501
“The causes of the effects associated with medical cupping vessels, of drinking, and of thrown objects that, once released, travel through the air or along the ground must also be investigated in this way.”2075
1.10 · Discord and concord
I.60.1.10 · Wachsmuth pp. 501
“So too with sounds that appear swift or slow, high or low: sometimes they arrive in discord because of dissimilarity in the movement they cause within us, and sometimes in concord because of similarity.”2076
1.11 · The slower sounds catch the earlier movements
I.60.1.11 · Wachsmuth pp. 501
“For the slower sounds catch the movements of the earlier, faster sounds when those movements are already subsiding and have become similar to the movements with which the slower sounds, approaching later, move them.”2077
1.12 · A single experience from high and low
I.60.1.12 · Wachsmuth pp. 501
“On catching them, they do not disturb them by imposing a different movement. Instead, they join on the beginning of a slower movement [and] in accordance with ⟨the⟩ likeness of the faster one as it dies away, and blend a single experience from high and low sound.”2078
1.13 · Pleasure and intelligent delight
I.60.1.13 · Wachsmuth pp. 501
“Hence they provide pleasure to those without understanding, but gladness to those with understanding, through the movement of divine harmony arising in mortal motions.”2079
1.14 · Water, lightning, amber, and magnets
I.60.1.14 · Wachsmuth pp. 501
“Moreover, all flows of water, the falls of thunderbolts, and the wonders associated with the attraction of amber and Heraclean stones: in none of these is there ever any pulling force.”2080
1.15 · How the apparent marvels arise
I.60.1.15 · Wachsmuth pp. 501-502
“The absence of any void, their driving one another around, and [the] fact that, as they separate and combine, all of them exchange places and travel each to its own seat: through these processes interwoven with one another, the apparent marvels will prove to have been produced, to anyone who investigates properly.”2081
1.16 · Breathing and the distribution of nourishment
I.60.1.16 · Wachsmuth pp. 502
“Breathing too, from which our account began, has come about in the same manner and through these processes, as was said earlier. Fire cuts up the food and, swinging within, follows the breath; through this shared oscillation it fills the vessels from the belly by drawing up the cut particles from there. For these reasons, streams of nourishment have thus come to flow throughout the whole body in every animal.”2082
