The Anatomy of Melancholy: Philosophy Classic. Robert Burton

of touching, hearing, seeing, smelling, tasting, to which you may add Scaliger's sixth sense of titillation, if you please; or that of speech, which is the sixth external sense, according to Lullius. Inward are three—common sense, phantasy, memory. Those five outward senses have their object in outward things only, and such as are present, as the eye sees no colour except it be at hand, the ear sound. Three of these senses are of commodity, hearing, sight, and smell; two of necessity, touch, and taste, without which we cannot live. Besides, the sensitive power is active or passive. Active in sight, the eye sees the colour; passive when it is hurt by his object, as the eye by the sunbeams. According to that axiom, visibile forte destruit sensum. [982]Or if the object be not pleasing, as a bad sound to the ear, a stinking smell to the nose, &c.

      Sight.] Of these five senses, sight is held to be most precious, and the best, and that by reason of his object, it sees the whole body at once. By it we learn, and discern all things, a sense most excellent for use: to the sight three things are required; the object, the organ, and the medium. The object in general is visible, or that which is to be seen, as colours, and all shining bodies. The medium is the illumination of the air, which comes from [983]light, commonly called diaphanum; for in dark we cannot see. The organ is the eye, and chiefly the apple of it, which by those optic nerves, concurring both in one, conveys the sight to the common sense. Between the organ and object a true distance is required, that it be not too near, or too far off! Many excellent questions appertain to this sense, discussed by philosophers: as whether this sight be caused intra mittendo, vel extra mittendo, &c., by receiving in the visible species, or sending of them out, which [984]Plato, [985]Plutarch, [986]Macrobius, [987]Lactantius and others dispute. And, besides, it is the subject of the perspectives, of which Alhazen the Arabian, Vitellio, Roger Bacon, Baptista Porta, Guidus Ubaldus, Aquilonius, &c., have written whole volumes.

      Hearing.] Hearing, a most excellent outward sense, "by which we learn and get knowledge." His object is sound, or that which is heard; the medium, air; organ, the ear. To the sound, which is a collision of the air, three things are required; a body to strike, as the hand of a musician; the body struck, which must be solid and able to resist; as a bell, lute-string, not wool, or sponge; the medium, the air; which is inward, or outward; the outward being struck or collided by a solid body, still strikes the next air, until it come to that inward natural air, which as an exquisite organ is contained in a little skin formed like a drum-head, and struck upon by certain small instruments like drum-sticks, conveys the sound by a pair of nerves, appropriated to that use, to the common sense, as to a judge of sounds. There is great variety and much delight in them; for the knowledge of which, consult with Boethius and other musicians.

      Smelling.] Smelling is an "outward sense, which apprehends by the nostrils drawing in air;" and of all the rest it is the weakest sense in men. The organ in the nose, or two small hollow pieces of flesh a little above it: the medium the air to men, as water to fish: the object, smell, arising from a mixed body resolved, which, whether it be a quality, fume, vapour, or exhalation, I will not now dispute, or of their differences, and how they are caused. This sense is an organ of health, as sight and hearing, saith [988]Agellius, are of discipline; and that by avoiding bad smells, as by choosing good, which do as much alter and affect the body many times, as diet itself.

      Taste.] Taste, a necessary sense, "which perceives all savours by the tongue and palate, and that by means of a thin spittle, or watery juice." His organ is the tongue with his tasting nerves; the medium, a watery juice; the object, taste, or savour, which is a quality in the juice, arising from the mixture of things tasted. Some make eight species or kinds of savour, bitter, sweet, sharp, salt, &c., all which sick men (as in an ague) cannot discern, by reason of their organs misaffected.

      Touching.] Touch, the last of the senses, and most ignoble, yet of as great necessity as the other, and of as much pleasure. This sense is exquisite in men, and by his nerves dispersed all over the body, perceives any tactile quality. His organ the nerves; his object those first qualities, hot, dry, moist, cold; and those that follow them, hard, soft, thick, thin, &c. Many delightsome questions are moved by philosophers about these five senses; their organs, objects, mediums, which for brevity I omit.

      SUBSECT. VII.—Of the Inward Senses.

      Common Sense.] Inner senses are three in number, so called, because they be within the brainpan, as common sense, phantasy, memory. Their objects are not only things present, but they perceive the sensible species of things to come, past, absent, such as were before in the sense. This common sense is the judge or moderator of the rest, by whom we discern all differences of objects; for by mine eye I do not know that I see, or by mine ear that I hear, but by my common sense, who judgeth of sounds and colours: they are but the organs to bring the species to be censured; so that all their objects are his, and all their offices are his. The fore part of the brain is his organ or seat.

      Phantasy.] Phantasy, or imagination, which some call estimative, or cogitative, (confirmed, saith [989]Fernelius, by frequent meditation,) is an inner sense which doth more fully examine the species perceived by common sense, of things present or absent, and keeps them longer, recalling them to mind again, or making new of his own. In time of sleep this faculty is free, and many times conceive strange, stupend, absurd shapes, as in sick men we commonly observe. His organ is the middle cell of the brain; his objects all the species communicated to him by the common sense, by comparison of which he feigns infinite other unto himself. In melancholy men this faculty is most powerful and strong, and often hurts, producing many monstrous and prodigious things, especially if it be stirred up by some terrible object, presented to it from common sense or memory. In poets and painters imagination forcibly works, as appears by their several fictions, antics, images: as Ovid's house of sleep, Psyche's palace in Apuleius, &c. In men it is subject and governed by reason, or at least should be; but in brutes it hath no superior, and is ratio brutorum, all the reason they have.

      Memory.] Memory lays up all the species which the senses have brought in, and records them as a good register, that they may be forthcoming when they are called for by phantasy and reason. His object is the same with phantasy, his seat and organ the back part of the brain.

      Affections of the Senses, sleep and waking.] The affections of these senses are sleep and waking, common to all sensible creatures. "Sleep is a rest or binding of the outward senses, and of the common sense, for the preservation of body and soul" (as Scaliger [990]defines it); for when the common sense resteth, the outward senses rest also. The phantasy alone is free, and his commander reason: as appears by those imaginary dreams, which are of divers kinds, natural, divine, demoniacal, &c., which vary according to humours, diet, actions, objects, &c., of which Artemidorus, Cardanus, and Sambucus, with their several interpretators, have written great volumes. This litigation of senses proceeds from an inhibition of spirits, the way being stopped by which they should come; this stopping is caused of vapours arising out of the stomach, filling the nerves, by which the spirits should be conveyed. When these vapours are spent, the passage is open, and the spirits perform their accustomed duties: so that "waking is the action and motion of the senses, which the spirits dispersed over all parts cause."

      SUBSECT. VIII.—Of the Moving Faculty.

      Appetite] This moving faculty is the other power of the sensitive soul, which causeth all those inward and outward animal motions in the body. It is divided into two faculties, the power of appetite, and of moving from place to place. This of appetite is threefold, so some will have it; natural, as it signifies any such inclination, as of a stone to fall downward, and such actions as retention, expulsion, which depend not on sense, but are vegetal, as the appetite of meat and drink; hunger and thirst. Sensitive is common to men and brutes. Voluntary, the third, or intellective, which commands the other two in men, and is a curb unto them, or at least should be, but for the most part is captivated and overruled by them; and men are led like beasts by sense, giving reins to their concupiscence and several lusts. For by this appetite the soul is led or inclined to follow that good which the senses shall approve, or avoid that which they hold evil: his object being good or evil, the one he embraceth, the other he rejecteth; according to that aphorism, Omnia appetunt bonum, all things seek their own good, or at least seeming good. This power is inseparable from sense, for where sense is,
