others for converfition. Of the Motions, thofe which come from without, and flow into the a^-iprehenfivepart, arefenfible; thofe which fall not under ccmprehenlion- arc infenfible, whe¬ ther b)' reafon that the afFeded bodies are more earthy, or that the motions are weaker. What- foever motions change nature , are painful ; whatfopvcr comply , with her, are named plea- fures.
• Of the Senfes, God enlightned our fight for contemplation of Celeftials, and apprehenfion of Science. Hearing, he framed perceptive of Difeourfe and of Mufick. Of this, if any be deltitute front his birth, he will alfo be uncapa- ble offtpeaking. Whence we fay. This fenfe is neared: aliy’d to reafon All that are termed afleclions of bodies, are denominated with refe¬ rence to the Touch, and their inclinations to a place; for, the Touch dijudicates vital faculties ; warm, cold ; dry, moift ; fmooth, rough ; yield¬ ing, refiding ; fofc, hard ; but heavy and light, the Touch prejudicates, Reafon defines by in¬ clination to move to the middle, and from the middle; below, and the middle, they affirm to be the fame thing, for the center of a Globe is below, whatfoever is betwixt that and the cir¬ cumference is above. Heat feems to confift of rare parts, and difgregates bodies; Cold, of more denfe parts, and bindeth the pores. The Tafte refembles the Touch in concretion and diferetion, and in penetration of the pores, and in its objects, which are either harfli ' or fmooth. Thofe which have an abfterfive facul¬ ty , dupifying the tongue , are bitter ; thofe which are moderately abderfive , fait; thofe which inflame and pierce further into the fleili, acid. Contrary to thefe, are fmocth and fweet. The kinds of Odor are not didindt, for they in- finuate through narrow pores, which are too folid to be contradfed and dilated by putrefadti- on, and concodlion of earth and earthly things. They are fweet or ftinking. Voice is a percuffion in the air, paffing to the foul through the ears, whofe pores extend to the Liver. In the ears is a fpiric, whofe motion is Hearing. Of voice and hearing fome are fwift, the ffiarp; fome flow, the flat ; the mean, are incommenfurable. Again, one is much and diffufed, the another fmall and contradled, the low: one is ordered accor¬ ding to proportions, the harmonious^ another dif- orderly and unpropordonate, the inharmonious. The fourth kind of Senfibles is mod various and • multiform, termed Vifibles, comprifing all co¬ lours, and innumerable coloured things. The primary colours are four. White, Black, Bright, Purplep/che reft are made by commixdon of thefe. White difperfeth the fight, Black contradls it ; asHoediffufeth the touch. Cold contradlsit ; Bitter contradteth the tafte,andSweetdiffipates it.
The bbdies of creatures that breathe air, are nouridied by aliment, diftributed by the veins through the whole frame defluxively,as by chan¬ nels; and irrigated by thefpirit which diffufeth it to theutnioft bounds. Refpiration is made(there being no vacuity in nature) by influxion, andat- tradion of the air in the room of that which iffu- eth forth at invifible vents, out of which allb fweat cvaporat:es.Now fomethingof it being wafted by the natural heat, it is necelfary fomething be in¬ troduced’ to fupply that which was confiimed ;
otherwife there would be a vacuity, which is im- poffible; Fora living creature could not berefto- red by perpetual fluxion, and entire, if the body • were disjoyn’d by vacuity. The like compofiti- on of Organs is likewife in inanimatethings,vvith an analogical refpiration; a Cupping-glafs and Amber are refemblances of refpiration, for the fpirits evaporate through the body, and enter a- gain at the mouth and noftrils by refpiration ; thenagain, VikeEurtpus, it is brought round into the body, which by thefe effluxions is extended. The cupping-glafs, the air being confumed by fire, attrads moifture ; the Amber, by emiffion of fpirits, attrads the body that is like to it. All ali¬ ment is taken into the body from the root of the heart, and the fountain of the ventricle ; if the acceffion be more than the defiuxion, it is termed Growth ; if the contrary, Decay. The Acmacon-^ fifts m the confine betwixt thefe two, and is con¬ ceived to be the equality of acceffion and defluxi¬ on. When the ligaments of the conltitucion are diflfolv’dj fo as there is nopaflTage for the breath, or diftribution of Aliment, the Animal dies.There are many things which are pernicious to life, and caufe death; v/hereofone is termed, Sick- nefs. The origines of fickneft are the difpropor- tions of the primary faculties : if the Ample fa¬ culties, Heat, Cold, Humidity, Siccity, abound, or are Deficient, then follow Mutations, and al¬ terations of the blood, by corruption, and depra¬ vations of the Confumpeive flelh : If according to the changes into Sharp, or Salt, or Acid (hu¬ mours) the turnings of the Blood, or Confump- tions of the flefli be caufed ; for hence are gene¬ rated Choler and Flegm. Unwholefome Chyles, and putrefadion of Humours, areinconfiderable except they be deep ; but thofe whofe caufes lie in the bones, are not eafily cur’d ; thofe which arifeout of the marrow are painful. The Extre¬ mities of Difeafesare Wind, Choler, Flegm, in- creafing and flowing, into places not proper to them, or into the vital parts, for then obtaining abetter place, they expel their neighbours, and fettle there, and affliding the bodies, they refolve them into themfeves.
Thefe are the Difeafes of theBody .Out of thefe arife many fickneffes of the foul, feveral of feve- ral faculties ; of the fenfitive, ftupidity ; of the reminifeent, forgetfulnefs ; of the defiderative, loathing, and exceffive appetite ; of the Pathe- tick, wild paffions, and furious frenfies ; of the rational, indocility and indiferetion. The forces of Vice, are pleafuresand griefs, defires and fears, raifed out of the body, mingled with the foul, and eXprefs’d by various names. Loves, Defires, dilfolute affedions, impetuous Angers, deep Ma¬ lices, various Longings, inordinate Delights. In a word, to behave our felves amifs as to paffions, or to fubdue them, is the bound betwixt virtue and vice } for to be exceffive in them, or too hard for them, put us in a good or bad condition. To thefe inclinations the temper of the body may contribute much: if vehement, fervent, or any way extraordinary, it tranfports us to Melancholy and extravagant lufts. For the parts being over¬ flown by thefe detluxions, make the conftitution of the body rather hydropical than found,whence arife fadnefs, forgetfulnefs, folly, and confterna- tion.
