about these operations. And thence the words that stand for them, by the greatest part of men of the same language, are not understood v. g. colshire, drilling, filtration, cohobation, are words standing for certain complex ideas, which being seldom in the minds of any but those few, whose particular employments do at every turn suggest them to their thoughts, those names of them are not generally understood but by smiths and chymists, who having framed the complex ideas which these words stand for, and having given names to them, or received them from others, upon hearing of these names in communication, readily conceive those ideas in their minds; as by cohobation, all the simple ideas of distilling, and the pouring the liquor distilled from any thing, back upon the remaining matter, and distilling it again. Thus we see, that there are great varieties of simple ideas, as of tastes and smells, which have no names, and of modes many more: which either not having been generally enough observed, or else not being of any great use to be taken notice of, in the affairs and converse of men, they have not had names given to them, and so pass not for species. This we shall have occasion hearafter to consider more at large, when we come to speak of words.

CHAPTER XIX.

OF THE MODES OF THINKING.

§. 1. Sensation, remembrance, contemplation, &c.-When the mind turns its view inwards upon itself, and contemplates its own actions, thinking is the first that occurs. In it the mind observes a great variety of modifications, and from thence receives distinct ideas. Thus the perception which actually accompanies, and is annexed to, any impression on the body, made by an external object, being distinct from all other modifications of thinking, furnishes the mind with a distinct idea, which we call sensation; which is, as it were, the actual entrance of any idea into the understanding by the senses. The same idea, when it again recurs without the operation of the like object on the external sensory, is remembrance: if it be sought after by the mind, and with pain and endeavour found, and brought again in view, it is recollection: if it be held there long under attentive consideration, it is contemplation when ideas float in our mind, without any reflection or regard of the understanding, it is that which the French call reverie; our language has scarce a name for it. When the

ideas that offer themselves (for, as I have observed in another place, whilst we are awake, there will always be a train of ideas succeeding one another in our minds), are taken notice of, and, as it were, registered in the memory, it is attention: when the mind, with great earnestness, and of great choice, fixes its view on any idea, considers it on all sides, and will not be called off by the ordinary solicitation of other ideas, it is that we call intention, or study; sleep, without dreaming, is rest from all these; and dreaming itself, is the having of ideas (whilst the outward senses are stopped, so that they receive not outward objects with their usual quickness) in the mind, not suggested by any external objects, or known occasion, nor under any choice or conduct of the understanding at all: and whether that, which we call extacy, be not dreaming with the eyes open, I leave to be examined. §. 2. These are some few instances of those various modes of thinking, which the mind may observe in itself, and so have as distinct ideas of, as it hath of white and red, a square or a circle, I do not pretend to enumerate them all, nor to treat at large of this set of ideas, which are got from reflection: that would be to make a volume. It suffices to my present purpose, to have shown here, by some few examples, of what sort these ideas are, and how the mind comes by them; especially since I shall have occasion hereafter to treat more at large of reasoning, judging, volition, and knowledge, which are some of the most considerable operations of the mind, and modes of thinking.

§. 3. The various attention of the mind in thinking. But, perhaps, it may not be an unpardonable digression, nor wholly impertinent to our present design, if we reflect here upon the different state of the mind in thinking, which those instances of attention, reverie, and dreaming, &c. before-mentioned, naturally enough suggest. That there are ideas, some or other, always present in the mind of a waking man, every one's experience convinces him; though the mind employs itself about them with several degrees of attention. Sometimes the mind fixes itself with so much earnestness on the contemplation of some objects, that it turns their ideas on all sides, remarks their relations and circumstances, and views every part so nicely, and with such intention, that it shuts out all other thoughts, and takes no notice of the ordinary impressions made then on the senses, which at another season would produce very sensible perceptions at other times, it barely observes the train of ideas that succeed in the understanding, without directing and pursuing any of them; and at other times, it lets them pass almost quite unregarded, as faint shadows that make no impression.

§. 4. Hence it is probable that thinking is the action, not

essence, of the soul.-This difference of intention and remission of the mind in thinking, with a great variety of degrees, between earnest study, and very near minding nothing at all, every one, I think, has experimented in himself. Trace it a little farther, and you find the mind in sleep, retired as it were from the senses, and out of the reach of those motions made on the organs of sense, which at other times produce very vivid and sensible ideas. I need not, for this, instance in those who sleep out whole stormy nights, without hearing the thunder, or seeing the lightning, or feeling the shaking of the house, which are sensible enough to those who are waking. But in this retirement of the mind from the senses, it often retains a yet more loose and incoherent manner of thinking, which we call dreaming; and last of all, sound sleep closes the scene quite, and puts an end to all appearances. This, I think, almost every one has experience of in himself, and his own observation without difficulty leads him thus far. That which I would farther conclude from hence, is, that since the mind can sensibly put on, at several times, several degrees of thinking; and be sometimes even in a waking man so remiss, as to have thoughts dim and obscure to that degree, that they are very little removed from none at all; and at last, in the dark retirements of sound sleep, loses the sight perfectly of all ideas whatsoever; since, I say, this is evidently so in matter of fact, and constant experience, I ask, whether it be not probable, that thinking is the action, and not the essence, of the soul? Since the operations of agents will easily admit of intention and remission; but the essences of things, are not conceived capable of any such variation. But this by the by.

CHAPTER XX.

OF MODES OF PLEASURE AND PAIN.

§. 1. Pleasure and pain simple ideas.-Amongst the simple ideas which we receive both from sensation and reflection, pain and pleasure are two very considerable ones. For as in the body, there is sensation barely in itself, or accompanied with pain or pleasure; so the thought, or perception of the mind, is simply so, or else accompanied also with pleasure or pain, delight or trouble, call it how you please. These, like other simple ideas, cannot be described, nor their names defined; the way of knowing them, is, as of the simple ideas of the senses, only by experience. For to define them by the presence of good or

evil, is no otherwise to make them known to us, than by making us reflect on what we feel in ourselves, upon the several and various operations of good and evil upon our minds, as they are differently applied to, or considered by us.

§. 2. Good and evil, what.-Things then are good or evil, only in reference to pleasure or pain. That we call good, which is apt to cause or increase pleasure, or diminish pain in us; or else to procure, or preserve, us the possession of any other good, or absence of evil. any And, on the contrary, we name that

evil, which is apt to produce or increase any pain, or diminish any pleasure in us; or else to procure us any evil, or deprive us of any good. By pleasure and pain, I must be understood to mean of body or mind, as they are commonly distinguished; though, in truth, they be only different constitutions of the mind, sometimes occasioned by disorder in the body, sometimes by thoughts of the mind.

§. 3. Our passions moved by good and evil.-Pleasure and pain, and that which causes them, good and evil, are the hinges on which our passions turn; and if we reflect on ourselves, and observe how these, under various considerations, operate in us; what modifications or tempers of mind, what internal sensations (if I may so call them), they produce in us, we may thence form to ourselves the ideas of our passions.

§. 4. Love. Thus any one reflecting upon the thought he has of the delight which any present or absent thing is apt to produce in him, has the idea we call love. For when a man declares in autumn, when he is eating them, or in spring, when there are none, that he loves grapes, it is no more but that the taste of grapes delights him; let an alteration of health or constitution destroy the delight of their taste, and he then can be said to love grapes no longer.

§. 5. Hatred. On the contrary, the thought of the pain which any thing present or absent is apt to produce in us, is what we call hatred Were it my business here to enquire any farther than into the bare ideas of our passions, as they depend on different modifications of pleasure and pain, I should remark, that our love and hatred of inanimate insensible beings, is commonly founded on that pleasure and pain which we receive from their use and application any way to our senses, though with their destruction: but hatred or love, to beings capable of happiness or misery, is often the uneasiness or delight which we find in ourselves, arising from a consideration of their very being or happiness. Thus the being and welfare of a man's children or friends producing constant delight in him, he is said constantly to love them. But it suffices to note, that our ideas

of love and hatred, are but the dispositions of the mind, in respect of pleasure and pain in general, however caused in us.

§. 6. Desire. The uneasiness a man finds in himself upon the absence of any thing, whose present enjoyment carries the idea of delight with it, is that we call desire, which is greater or less, as that uneasiness is more or less vehement. Where, by the by, it may perhaps be of some use to remark, that the chief, if not only spur to human industry and action, is uneasiness. For whatsoever good is proposed, if its absence carries no displeasure or pain with it; if a man be easy and content without it, there is no desire of it, nor endeavour after it; there is no more but a bare velleity, the term used to signify the lowest degree of desire, and that which is next to none at all, when there is so little uneasiness in the absence of any thing, that it carries a man no farther than some faint wishes for it, without any more effectual or vigorous use of the means to attain it. Desire also is stopped or abated by the opinion of the impossibility or unattainableness of the good proposed, as far as the uneasiness is cured or allayed by that consideration. This might carry our thoughts farther, were it seasonable in this place.

§. 7. Joy.-Joy is a delight of the mind, from the consideration of the present or assured approaching possession of a good; and we are then possessed of any good, when we have it so in our power, that we can use it when we please. Thus a man almost starved, has joy at the arrival of relief, even before he has the pleasure of using it: and a father, in whom the very well-being of his children causes delight, is always, as long as his children are in such a state, in the possession of that good; for he needs but to reflect on it, to have that pleasure.

§. 8. Sorrow.-Sorrow is uneasiness in the mind, upon the thought of a good lost, which might have been enjoyed longer; or the sense of a present evil.

§. 9. Hope.-Hope is that pleasure in the mind which every one finds in himself, upon the thought of a profitable future enjoyment of a thing which is apt to delight him.

§. 10. Fear. Fear is an uneasiness of the mind, upon the thought of future evil likely to befal us.

§. 11. Despair.-Despair is the thought of the unattainableness of any good, which works differently in men's minds, sometimes producing uneasiness or pain, sometimes rest and indolency.

§. 12. Anger.-Anger is uneasiness or discomposure of the mind, upon the receipt of any injury, with a present purpose of
