These testimonies I think are enough; and reason confirms Plato’s opinion by arguments drawn first from sense. For when the windpipe is wounded, no drink will go down; but as if the pipe were broken it runs out, though the weasand be whole and unhurt. And all know that in the inflammation of the lungs the patient is troubled with extreme thirst; the heat or dryness or some other cause, together with the inflammation, making the appetite intense. But a stronger evidence than all these follows. Those creatures that have very small lungs, or none at all, neither want nor desire drink, because to some parts there belongs a natural appetite to drink, and those that want those parts have no need to drink, nor any appetite to be supplied by it. But more, the bladder would seem unnecessary; for, if the weasand receives both meat and drink and conveys it to the belly, the superfluous parts of the liquids would not want a proper passage, one common one would suffice as a canal for both that were conveyed to the same vessel by the same passage. But now the bladder is distinct from the guts, because the drink goes from the lungs, and the meat from the stomach; they being separated as we take them down. And this is the reason that in our water nothing can be found that either in smell or color resembles dry food. But if the drink were mixed with the dry meat in the belly, it must be impregnant with its qualities, and not come forth so simple and untinged. Besides, a stone is never found in the stomach, though it is likely that the moisture should be coagulated there as well as in the bladder, if all the liquor were conveyed through the weasand into the belly. But it is probable that the weasand robs the windpipe of a sufficient quantity of liquor as it is going down, and useth it to soften and concoct the meat. And therefore its excrement is never purely liquid; and the lungs, disposing of the moisture, as of the breath, to all the parts that want it, deposit the superfluous position in the bladder. And I am sure that this is a much more probable opinion than the other. But which is the truth cannot perhaps be discovered, and therefore it is not fit so peremptorily to find fault with the most acute and most famed philosopher, especially when the matter is so obscure, and the Platonists can produce such considerable reasons for their opinion.
