the names, which in several arts have been found out, and applied to several complex ideas of modified actions belonging to their several trades, for dispatch sake, in their direction or discourses about them. Which ideas are not generally framed in the minds of men not conversant 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, cohabation, 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 thein to their thoughts, those names of them are not generally understood but by smiths and chymnists; who having framed the complex ideas which these words stand for, and having given names to thein, or received then 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 sinells, 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 hereafter to consider more at large, when we come to speak of words.

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 cone templation. 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 carnestness, and of choice, fixes iis view on any idea, considers it on all sides, and will not be called off by the ordinary solicitation of other idcas, it is thać 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 under. standing at all. And whether that, which we call extasy, 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. The various . 3. But perhaps it may not be an unattention of pardonable digression, nor wholly impertithe mind in nent to our présent design, if we reflect

king. 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 hiin, 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 shadow's that make no impression. Hence it is $. 4. This difference of intention, and probable that remission of the mind in thinking, with a thinking is great variety of degrees between earnest the action, study, and very near minding nothing at not essence of the soul. all, every one, I think, hạs experilgented

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 those who are waking : but in this retirement of the mind from the senses, it often retains à 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.

C HA P. XX. Of Nodes of Pleasure and Pain. §. 1. AMONGST the simple ideas, Pleasure and I n which we receive both from pain simple

ideas. 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.

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 any evil. 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.
