CHAPTER VI

OF THE INTERIOR BEGINNINGS OF VOLUNTARY MOTIONS, COMMONLY CALLED THE PASSIONS; AND THE SPEECHES BY WHICH THEY ARE EXPRESSED

THERE be in animals two sorts of motions peculiar to them: One called vital, begun in generation, and continued without interruption through their whole life; such as are the course of the blood, the pulse, the breathing, the concoction, nutrition, excretion, etc.; to which motions there needs no help of imagination: the other is animal motion, otherwise called voluntary motion; as to go, to speak, to move any of our limbs, in such manner as is first fancied in our minds. That sense is motion in the organs and interior parts of man's body, caused by the action of the things we see, hear, etc., and that fancy is but the relics of the same motion, remaining after sense, has been already said in the first and second chapters. And because going, speaking, and the like voluntary motions depend always upon a precedent thought of whither, which way, and what, it is evident that the imagination is the first internal beginning of all voluntary motion. And although unstudied men do not conceive any motion at all to be there, where the thing moved is invisible, or the space it is moved in is, for the shortness of it, insensible; yet that doth not hinder but that such motions are. For let a space be never so little, that which is moved over a greater space, whereof that little one is part, must first be moved over that. These small beginnings of motion within the body of man, before they appear in walking, speaking, striking, and other visible actions, are commonly called endeavour.

This endeavour, when it is toward something which causes it, is called appetite, or desire, the latter being the general name, and the other oftentimes restrained to signify the desire of food, namely hunger and thirst. And when the endeavour is from ward something, it is generally called aversion. These words appetite and aversion we have from the Latins; and they both of them signify the motions, one of approaching, the other of retiring. So also do the Greek words for the same, which are orme and aphorme. For Nature itself does often press upon men those truths which afterwards, when they look for somewhat beyond Nature, they stumble at. For the Schools find in mere appetite to go, or move, no actual motion at all; but because some motion they must acknowledge, they call it metaphorical motion, which is but an absurd speech; for though words may be called metaphorical, bodies and motions cannot.

That which men desire they are said to love, and to hate those things for which they have aversion. So that desire and love are the same thing; save that by desire, we signify the absence of the object; by love, most commonly the presence of the same. So also by aversion, we signify the absence; and by hate, the presence of the object.

Of appetites and aversions, some are born with men; as appetite of food, appetite of excretion, and exoneration (which may also and more properly be called aversions, from somewhat they feel in their bodies), and some other appetites, not many. The rest, which are appetites of particular things, proceed from experience and trial of their effects upon themselves or other men. For of things we know not at all, or believe not to be, we can have no further desire than to taste and try. But aversion we have for things, not only which we know have hurt us, but also that we do not know whether they will hurt us, or not.

Those things which we neither desire nor hate, we are said to contemn: contempt being nothing else but an immobility or contumacy of the heart in resisting the action of certain things; and proceeding from that the heart is already moved otherwise, by other more potent objects, or from want of experience of them.

And because the constitution of a man's body is in continual mutation, it is impossible that all the same things should always cause in him the same appetites and aversions: much less can all men consent in the desire of almost any one and the same object.

But whatsoever is the object of any man's appetite or desire, that is it which he for his part calleth good; and the object of his hate and aversion, evil; and of his contempt, vile and inconsiderable. For these words of good, evil, and contemptible are ever used with relation to the person that useth them: there being nothing simply and absolutely so; nor any common rule of good and evil to be taken from the nature of the objects themselves; but from the person of the man, where there is no Commonwealth; or, in a Commonwealth, from the person that representeth it; or from an arbitrator or judge, whom men disagreeing shall by consent set up and make his sentence the rule thereof.

The Latin tongue has two words whose significations approach to those of good and
