But in the soles of the feet there is the same plan as in the hands, but yet very different: for since these are, as it were, the foundations of the whole body, [1910] the admirable Artificer has not made them of a round appearance, lest man should be unable to stand, or should need other feet for standing, as is the case with quadrupeds; but He has formed them of a longer and more extended shape, that they might make the body firm by their flatness, [1911] from which circumstance their name was given to them. The toes are of the same number with the fingers, for the sake of appearance rather than utility; and on this account they are both joined together, and short, and put together by gradations; and that which is the greatest of these, since it was not befitting that it should be separated from the others, as in the hand, has been so arranged in order, that it appears to differ from the others in magnitude and the small space which intervenes. This beautiful union [1912] of them strengthens the pressure of the feet with no slight aid; for we cannot be excited to running, unless, our toes being pressed against the ground, and resting upon the soil, we take an impetus and a spring. I appear to have explained all things of which the plan is capable of being understood. I now come to those things which are either doubtful or obscure.

Chap. XIV.--Of the Unknown Purpose of Some of the Intestines.
It is evident that there are many things in the body, the force and purpose of which no one can perceive but He who made them. Can any one suppose that he is able to relate what is the advantage, and what the effect, of that slight transparent membrane by which the stomach is netted over and covered? What the twofold resemblance of the kidneys? which Varro says are so named because streams of foul moisture arise from these; which is far from being the case, because, rising on either side of the spine, they are united, and are separated from the intestines. What is the use of the spleen? What of the liver? Organs which appear as it were to be made up [1913] of disordered blood. What of the very bitter moisture of the gall? What of the heart? unless we shall happen to think that they ought to be believed, who think that the affection of anger is placed in the gall, that of fear in the heart, of joy in the spleen. But they will have it that the office of the liver is, by its embrace and heat, to digest the food in the stomach; some think that the desires of the amorous passions are contained in the liver.
First of all, the acuteness of the human sense is unable to perceive these things, because their offices lie concealed; nor, when laid open, do they show their uses. For, if it were so, perhaps the more gentle animals would either have no gall at all, or less than the wild beasts; the more timid ones would have more heart, the more lustful would have more liver, the more playful more spleen. As, therefore, we perceive that we hear with our ears, that we see with our eyes, that we smell with our nostrils; so assuredly we should perceive that we are angry with the gall, that we desire with the liver, that we rejoice with the spleen. Since, therefore, we do not at all perceive from what part those affections come, it is possible that they may come from another source, and that those organs may have a different effect to that which we suppose. We cannot prove, however, that they who discuss these things speak falsely. But I think that all things which relate to the motions of the mind and soul, are of so obscure and profound a nature, that it is beyond the power of man to see through them clearly. This, however, ought to be sure and undoubted, that so many objects and so many organs have one and the same office--to retain the soul in the body. But what office is particularly assigned to each, who can know, except the Designer, to whom alone His own work is known?

Chap. XV.--Of the Voice.
But what account can we give of the voice? Grammarians, indeed, and philosophers, define the voice to be air struck by the breath; from which words [1914] derive their name: which is plainly false. For the voice is not produced outside of the mouth, but within, and therefore that opinion is more probable, that the breath, being compressed, when it has struck against the obstacle presented by the throat, forces out the sound of the voice: as when we send down the breath into an open hemlock stalk, having applied it to the lips, and the breath, reverberating from the hollow of the stalk, and rolled back from the bottom, while it returns [1915] to that descending through meeting with itself, striving for an outlet, produces a sound; and the wind, rebounding by itself, is animated into vocal breath. Now, whether this is true, God, who is the designer, may see. For the voice appears to arise not from the mouth, but from the innermost breast. In fine, even when the mouth is closed, a sound such as is possible is emitted from the nostrils. Moreover, also, the voice is not affected by that greatest breath with which we gasp, but with a light and not compressed breath, as often as we wish. It has not therefore been comprehended in what manner it takes place, or what it is altogether. And do not imagine that I am now falling into the opinion of the Academy, for all things are not incomprehensible. For as it must be confessed that many things are unknown, since God has willed that they should exceed the understanding of man; so, however, it must be acknowledged that there are many which may both be perceived by the senses and comprehended by the reason. But we shall devote an entire treatise to the refutation of the philosophers. Let us therefore finish the course over which we are now running.

Chap. XVI.--Of the Mind and Its Seat.
That the nature of the mind is also incomprehensible, who can be ignorant, but he who is altogether destitute of mind, since it is not known in what place the mind is situated, or of what nature it is? Therefore various things have been discussed by philosophers concerning its nature and place. But I will not conceal what my own sentiments are: not that I should affirm that it is so--for in a doubtful matter it is the part of a foolish person to do this; but that when I have set forth the difficulty of the matter, you may understand how great is the magnitude off the divine works. Some would have it, that the seat of the mind is in the breast. But if this is so, how wonderful is it, that a faculty which is situated in an obscure and dark habitation should be employed in so great a light of reason and intelligence; then that the senses from every part of the body come together to it, so that it appears to be present in any quarter of the limbs! Others have said that its seat is in the brain and, indeed, they have used probable arguments, saying that it was doubtless befitting that that which had the government of the whole body should especially have its abode in the highest place, as though in the citadel of the body; and that nothing should be in a more elevated position than that which governs the whole by reason, just as the Lord Himself, and Ruler of the universe, is in the highest place. Then they say, that the organs which are the ministers of each sense, that is, of hearing, and seeing, and smelling, are situated in the head, and that the channels of all these lead not to the breast, but to the brain: otherwise we must be more slow in the exercise of our senses, until the power of sensation by a long course should descend through the neck even to the breast. These, in truth, do not greatly err, or perchance not at all. For the mind, which exercises control over the body, appears to be placed in the highest part, the head, as God is in heaven; but when it is engaged in any reflection, it appears to pass to the breast, and, as it were, to withdraw to some secret recess, that it may elicit and draw forth counsel, as it were, from a hidden treasury. And therefore, when we are intent upon reflection, and when the mind, being occupied, has withdrawn itself to the inner depth, [1916] we are accustomed neither to hear the things which sound about us, nor to see the things which stand in our way. But whether this is the case, it is assuredly a matter of admiration how this takes place, since there is no passage from the brain to the breast. But if it is not so, nevertheless it is no less a matter of admiration that, by some divine plan or other, it is caused that it appears to be so. Can any fail to admire that that living and heavenly faculty which is called the mind or the soul, is of such volubility [1917] that it does not rest even then when it is asleep; of such rapidity, that it surveys the whole heaven at one moment of time; and, if it wills, flies over seas, traverses lands and cities,--in short, places in its own sight all things which it pleases, however far and widely they are removed?
And does any one wonder if the divine mind of God, being extended [1918] through all parts of the universe, runs to and fro, and rules all things, governs all things, being everywhere present, everywhere diffused; when the strength and power of the human mind, though enclosed within a mortal body, is so great, that it can in no way be restrained even by the barriers of this heavy and slothful body, to which it is bound, from bestowing upon itself, in its impatience of rest, the power of wandering without restraint? Whether, therefore, the mind has its dwelling in the head or in the breast, can any one comprehend what power of reason effects, that that incomprehensible faculty either remains fixed in the marrow of the brain, or in that blood divided into two parts [1919] which is enclosed in the heart; and not infer from this very circumstance how great is the power of God, because the soul does not see itself, or of what nature or where it is; and if it did see, yet it would not be able to perceive in what manner an incorporeal substance is united with one which is corporeal? Or if the mind has no fixed locality, but runs here and there scattered through the whole body,--which is possible, and was asserted by Xenocrates, the disciple of Plato,--then, inasmuch as intelligence is present in every part of the body, it cannot be understood what that mind is, or what its qualities are, since its nature is so subtle and refined, that, though infused into solid organs by a living and, as it were, ardent perception, it is mingled with all the members.
But take care that you never think it probable, as Aristoxenus said, that the mind has no existence, but that the power of perception exists from the constitution of the body and the construction of the organs, as harmony does in the case of the lyre. For musicians call the stretching and sounding of the strings to entire strains, without any striking of notes in agreement with them, harmony. They will have it, therefore, that the soul in man exists in a manner like that by which harmonious modulation exists on the lyre; namely, that the firm uniting of the separate parts of the body and the vigour of all the limbs agreeing together, makes that perceptible motion, and adjusts [1920] the mind, as well-stretched things produce harmonious sound. And as, in the lyre, when anything has been interrupted or relaxed, the whole method of the strain is disturbed and destroyed; so in the body, when any part of the limbs receives an injury, the whole are weakened, and all being corrupted and thrown into confusion, the power of perception is destroyed: and this is called death. But he, if he had possessed any mind, would never have transferred harmony from the lyre to man. For the lyre cannot of its own accord send forth a sound, so that there can be in this any comparison and resemblance to a living person; but the soul both reflects and is moved of its own accord. But if there were in us anything resembling harmony, it would be moved by a blow from without, as the strings of the lyre are by the hands; whereas without the handling of the artificer, and the stroke of the fingers, they lie mute and motionless. But doubtless he [1921] ought to have beaten by the hand, that he might at length observe; for his mind, badly compacted from his members, was in a state of torpor.
