Chapter XXIII.

Of the Passions of the Body, and Whether the Soul Hath a Sympathetical Condolency with It.

The Stoics say that all the passions are seated in those parts of the body which are affected, the senses have their residence in the commanding part of the soul. Epicurus, that all the passions and all the senses are in those parts which are affected, but the commanding part is subject to no passion. Strato, that all the passions and senses of the soul are in the rational or commanding part of it, and are not fixed in those places which are affected; for in this place patience takes its residence, and this is apparent in terrible and dolorous things, as also in timorous and valiant individuals.

Book V Chapter I." Of Divination.

Plato and the Stoics introduce divination as a godlike enthusiasm, the soul itself being of a divine constitution, and this prophetic faculty being inspiration, or an illapse of the divine knowledge into man; and so likewise they account for interpretation by dreams. And these same allow many divisions of the art of divination. Xenophanes and Epicurus utterly refuse any such art of foretelling future contingencies. Pythagoras rejects all manner of divination which is by sacrifices. Aristotle and Dicaearchus admit only these two kinds of it, a fury by a divine inspiration, and dreams; they deny the immortality of the soul, yet they affirm that the mind of man hath a participation of something that is divine.

Chapter II." Whence Dreams do Arise.

Democritus says that dreams are formed by the illapse of adventitious representations. Strato, that the irrational part of the soul in sleep becoming more sensible is moved by the rational part of it. Herophilus, that dreams which are caused by divine instinct have a necessary cause; but dreams which have their origin from a natural cause arise from the soul’s forming within itself the images of those things which are convenient for it, and which will happen; those dreams which are of a constitution mixed of both these have their origin from the fortuitous appulse of images, as when we see those things which please us; thus it happens many times to those persons who in their sleep imagine they embrace their mistresses.

Chapter III." Of the Nature of Generative Seed.

Aristotle says, that seed is that thing which contains in itself a power of moving, whereby it is enabled to produce a being like unto that from whence it was emitted. Pythagoras, that seed is the sediment of that which nourisheth us, the froth of the purest blood, of the same nature of the blood and marrow of our bodies. Alcmaeon, that it is part of the brain. Plato, that it is the deflux of the spinal marrow. Epicurus, that it is a fragment torn from the body and soul. Democritus, that it proceeds from all the parts of the body, and chiefly from the principal parts, as the tissues and muscles.

Chapter IV." Whether the Sperm be a Body.

Leucippus and Zeno say, that it is a body and a fragment of the soul. Pythagoras, Plato, and Aristotle, that the spermatic faculty is incorporeal, as the mind is which moves the body; but the effused matter is corporeal. Strato and Democritus, that the essential power is a body; for it is like spirit.

Chapter V." Whether Women do Give a Spermatic Emission As Men Do.

Pythagoras, Epicurus, and Democritus say, that women have a seminal projection, but their spermatic vessels are inverted; and it is this that makes them have a venereal appetite. Aristotle and Plato, that they emit a material moisture, as sweat we see produced by exercise and labor; but that moisture has no spermatic power. Hippo, that women have a seminal emission, but not after the mode of men; it contributes nothing to generation, for it falls outside of the matrix; and therefore some women without coition, especially widows, give the seed. They also assert that from men the bones, from women the flesh proceed.

Chapter VI." How it is that Conceptions are Made.

Aristotle says, that conception takes place when the womb is drawn down by the natural purgation, and the monthly terms attract from the whole mass part of the purest blood, and this is met by the seed of man. On the contrary, there is a failure by the impurity and inflation of the womb, by fear and grief, by the weakness of women, or the decline of strength in men.

Chapter VII." After what Manner Males and Females are Generated.

Empedocles affirms, that heat and cold give the difference in the generation of males and females. Hence is it, as histories acquaint us, that the first men originated from the earth in the eastern and southern parts, and the first females in the northern parts. Parmenides is of opinion perfectly contrariant. He affirms that men first sprouted out of the northern earth, for their bodies are more dense; women out of the southern, for theirs are more rare and fine. Hippo, that the more compacted and strong sperm, and the more fluid and weak, discriminate the sexes. Anaxagoras and Parmenides, that the seed of the man is naturally cast from his right side into the right side of the womb, or from the left side of the man into the left side of the womb; there is an alteration in this course of nature when females are generated. Cleophanes, whom Aristotle makes mention of, assigns the generation of men to the right testicle, of women to the left. Leucippus gives the reason of it to the alteration or diversity of parts, according to which the man hath a yard, the female the matrix; as to any other reason he is silent. Democritus, that the parts common to both sexes are engendered indifferently; but the peculiar parts by the one that is more powerful. Hippo, that if the spermatic faculty be more effectual, the male, if the nutritive aliment, the female is generated.

Chapter VIII." By what Means it is that Monstrous Births are Effected.

Empedocles believes that monsters receive their origination from the abundance or defect of seed, or from its division into parts which are superabundant, or from some disturbance in the motion, or else that there is an error by a lapse into an unsuitable receptacle; and thus he presumes he hath given all the causes of monstrous conceptions. Strato, that it comes through addition, subtraction, or transposition of the seed, or the distension or inflation of the matrix. And some physicians say that the matrix suffers distortion, being distended with wind.

Chapter IX.

How it Comes to Pass that a Woman’s Too Frequent Conversation with a Man Hinders Conception.

Diocles the physician says that either no genital sperm is projected, or, if there be, it is in a less quantity than nature requires, or there is no prolific faculty in it; or there is a deficiency of a due proportion of heat, cold, moisture, and dryness; or there is a resolution of the generative parts. The Stoics attribute sterility to the obliquity of the yard, by which means it is not able to ejaculate in a due manner, or to the unproportionable magnitude of the parts, the matrix being so contracted as not to have a capacity to receive. Erasistratus assigns it to the womb’s being more callous or more carneous, thinner or smaller, than nature does require.

Chapter X.

Whence it is that One Birth Gives Two or Three Children.

Empedocles affirms, that the superabundance of sperm and the division of it causes the bringing forth of two or three infants. Asclepiades, that it is performed from the excellent quality of the sperm, after the manner that from the root of one barleycorn two or three stalks do grow; sperm that is of this quality is the most prolific. Erasistratus, that superfetation may happen to women as to irrational creatures; for, if the womb be well purged and very clean, then there can be divers births. The Stoics, that it ariseth from the various receptacles that are in the womb: when the seed illapses into the first and second of them at once, then there are conceptions upon conception; and so two or three infants are born.
