The Introduction.
ANthropologia or the Doctrine of Mans Nature, is, though com∣monly, yet rightly divided into two Parts: Anatomia which treats of the Body and its Parts; and Psychologia, which treats of the Soul.
Anatomia therefore [more rightly called Anatomy, that is Section, which Sr. Ignatius reckons as a kind of Martyrdom, Caelius terms Apertio an opening, and Tertulianus Prosectio a cutting up, whence the term Prosector, a Cutter up] that I may come to that which is my business; in as much as it is a part of Natural Philosophy [for* 1.1 Medicinal Anatomy how ever useful and of which Galen treats in his Anatomical Administration, we must leave to Physitians] hath for its Subject the Body of any Animal or Live-wight whatsoever, whether frequenting the Land or or Waters, flying in the Air, &c. and not only the Body of Man. But we are wont most of all to search into the structure of Mans Body. 1. Because of the great Perfection thereof, which* 1.2 is the Rule of Imperfection. 2. Because the sundry sorts of Animals are almost infinite, so that to dissect and search into all of them, the life of man in this Age of the World is not suffi∣cient. 3. Because of the incredible profit which thereby redounds to every man, who desires perfectly to know himself, and this House of his earthy Tabernacle, both the better to preserve Health and to cure Diseases: Nor can any man be a Natural Philosopher or deserve so to be called, unless he have the Doctrine of Anatomy at his fingers end, above all other Parts of Na∣tural Philosophy. Yet is not the Dissection of other Creatures therefore unprofitable, or to be* 1.3 neglected by an Anatomist, partly by reason of the Analogie and Correspondence they hold with the Body of Man, partly to attain to the Knowledg of the Motions of Living Creatures, and partly, to conclude, for the Exercise of an Anatomist and Surgeon. Democritus sought the Seat and Nature of Choler in Living Creatures. After him Galen dissected Apes and other Living Creatures, as also Severinus, Aldrovandus, Castellus, Br••nzerus, Panarolus and myself have cut up divers Living Creatures. By the cutting up of Creatures alive Asellius found out the Ven•• lacteae •••• milkie Veins, and Harvey and Walaeus found the motion of the Blood.
Moreover, because in regard of the vari•••• of its Actions, the Body of Man does not consist of one part all alike, but of sundry; therefore we must know that the whole Body is divided* 1.4 into Parts containing, Parts contained, and Parts moving, according to the ancient Doctrine of Hippocrates: that is to say, into solid Parts, Humors and Spirits. And in this large accep∣tation, all things are called Parts which make up and compleat the Body, even the Nails, Hairs, Fat and Marrow. But stricctly and properly that is called a Pa•••• which partakes of the form, and life of the whole, and such the Anatomists accounts 〈…〉〈…〉 so••i••t Parts, And therefore •…•…lius hath well defined a Part to be A Body 〈◊〉〈◊〉 to the whole, partaking of the common Life 〈…〉〈…〉 •…•…ted for the performance of some Functions or Use. But Galen accounts that a Part,* 1.5 which is a B•…•… •••• some sort joyned to the whole, and hath in part its own proper Circum∣sc•••••• 〈…〉〈…〉 part is properly;
- 1. Tha•• 〈…〉〈…〉 is 〈…〉〈…〉 but does not nourish any other Part. And so they ex∣clude the S•…•… H•…•…. 〈…〉〈…〉 also t•••• Fa••, which somtimes nourishes the Parts, and the* 1.6 Marrow of the Bone▪ 〈…〉〈…〉.
- 2. That which is solid.
- 3. Which hath a proper Circumscription of its own. The contrary whereof is in fat, which is terminated by the figure of the Parts adjacent.
- 4. Which is continued with the whole, Mathematically and Physically, both in respect of the Matter and Form joyntly considered.
- 5. Which is fitted for some Function or Use. And so Warts and Swellings, with other things which grow upon the living Body praeternaturally, are excluded.
And that we may understand what is ment by Function and Use, I shall briefly open the same. An Action or Function may be either private or publick. The private Action is that whereby the Parts provide for themselves; the publick is that whereby they provide for the* 1.7 whole live Creature. A publick Action as it is opposed to use, is the Action of the principal Part of an Organ which performes the whole Action. For every Action in the Body of a live∣wight, hath according to Galen, a peculiar Particle, by which it is performed. For Examples sake; The Skin hath of it self a private Action, such as the Attraction and Retention of Nourish∣ment &c. it hath also a publick action for the behoof of the whole Animal, viz. the discerning of the tangible Qualities, such as are perceived by the Sense of Feeling. So the action of the Liver•• •…•…od-making, of the Stones, Seed-making; of the Dugs Milk-making.
But the ••••••e, is that help which the less principal Parts afford the more principal, in the per∣formance* 1.8 •••• their Actions, which according to Galen is in all Parts, yea even in those which have no action at all. It springs chiefly from three Fountaines, and they are,
- 1. The proper Temper of the Part, that is to say the Symmetry or even proportion of the fir••t Qualities. For Examples sake, The Skin is in respect of the first Qualities temperate; and if
