They belong $. 8. Where and when are questions beto all beings. longing to all finite existences, and are by us always reckoned from some known parts of this sensible world, and from some certain epochs marked out to us by the motions observable in Without some such fixed parts or periods, the order of things would be lost to our finite understandings, in the boundless invariable oceans of duration and expansion ; which comprehend in them all finite beings, and in their full extent belong only to the Deity. And therefore we are not to wonder that we comprehend them not, and do so often find our thoughts at a loss, when we would consider them either abstractly in themselves, or as any way attributed to the first incomprehensible being. But when applied to any particular finite beings, the extension of any body is so much of that infinite space, as the bulk of the body takes up. And place is the position of any body, when considered at a certain distance from some other. As the idea of the particular duration of any thing is an idea of that portion of infinite duration, which passes during the existence of that thing; so the time when the thing existed is the idea of that space of duration which passed between some known and fixed period of duration, and the being of that thing. One shows the distance of the extremities of the bulk or existence of the same thing, as that it is a foot square, or lasted two years; the other shows the distance of it in place, or existence, from other fixed points of space or duration, as that it was in the middle of Lincoln’s-inn-fields, or the first degree of Taurus, and in the year of our Lord 1671, or the 1000 year of the Julian period; all which distances we measure by pre-conceived ideas of certain lengths of space and duration, as inches, feet, miles, and degrees; and in the other, minutes, days, and years, &c. All the parts

position; position *; it is the very nature of both of them to consist of parts : but their parts being all of the same kind, and without the mixture of any other idea, hinder them not from having a place amongst simple ideas. Could the mind, as in number, come to so small a part of extension or duration, as excluded divisibility, that would be, as it were, the indivisible unit, or idea; by repetition of which it would make its more enlarged ideas of extension and duration. But since the mind is not able to frame an idea of any space without parts; instead thereof it makes use of the common measures, which by familiar use, in each country, have imprinted themselves on the memory (as incles and feet; or cubits and parasangs; and so seconds, minutes, hours, days, and years in duration :) the mind makes use, I. say, of such ideas as these, as simple ones; and these are the component parts of larger ideas, which'the mind, upon occasion, makes by the addition of such known


lengths lengths which it is acquainted with. On the other side, the ordinary smallest measure we have of either is looked on as an unit in number, when the mind by division would reduce them into less fractions. Though on both sides, both in addition and division, either of space or duration, when the idea under consideration becomes very big or very small, its precise bulk becomes very obscure and confused; and it is the number of its repeated additions or divisions, that alone remains clear and distinct, as will easily appear to any one who will let his thoughts loose in the vast expansion of space, or divisibility of matter. Every part of duration is duration too; and every part of extension is extension, both of them capable of addition or division in infi- all nitum. But the least portions of either of them, whereof we have clear and distinct ideas, may perhaps be fittest to be considered by us, as the simple ideas of that kind, out of which our complex modes of space,

* It has been objected to Mr. Locke, that if space consists of parts, as it is confessed in this place, he should not have reckoned it in the number of simple ideas : because it seems to be inconsistent with what he says elsewhere, that a simple idea is uncompounded, and contains in it no. thing but one mi appearance or conception of the mind, and is not distinguishal in different ideas. It is farther objected, that Mr. Locke has not in the eleventh chapter of the second book, where he begins to speak of simple ideas, an exact definition of what he understands by the word simple ideas. To these difficulties Mr. Locke answers thus : To begin with the last, he declares, that he has not treated his subject in an order perfectly scholastic, having not had much fami. liarity with those sort of books during the writing of his, and not remembering at all the method in which they are written; and therefore his readers ought not to expect definitions regularly placed at the beginning of each new subject. Mr. Lacke contents himself to 'employ the principal terms that he uses, so that from his use of them the reader may easily comprehend what he means by them. But with respect to the term simple idea, he has had the good luck to define that in the place cited in the objection ; and therefore there is no reason to supply that defect. The question then is to know, whether the idea of extension agrees with this definition ? which will effectually agree to it, if it be understood in the sense which Mr. Locke had principally in his view : for that composition which he designed to exclude in that definition, was a composition of different ideas in the mind, and not a composition of the same kind in a thing whose essence consists in having parts of the same kind, where you san never come to a part entirely exempted from this composition. So

that if the idea of extension consists in having partes extra partes, (as the
schools speak) it is always, in the sense of Mr. Locke, a simple idea; be.
cause the idea of having partes extra partes cannot be resolved into two
other ideas. For the remainder of the objection made to Mr. Locke,
with respect to the nature of extension, Mr. Locke was aware of it, as
may be seen in ý. 9. chap. 15. of the second hook, where he says, that
« the least portion of space or extension, whereof we has a clear and
« distinct idea, may perhaps be the fittest to be considered by us as a sim.
“ ple idea of that kind, out of which our complex modes of space

and “ extension are made up." So that, according to Mr. Locke, it may very fitly be called a simple idea, since it is the least idea of space that the mind can form to itself, and that cannot be divided by the mind into any less

, whereof it has in itself any determined perception. From whence it fol. lows, that it is to the mind one simple idea ; and that is sufficient to take away this objection : for it is not the design of Mr. Locke, in this place, to discourse of any thing but concerning the idea of the mind. But if this is not sufficient to clear the difficulty, Mr. Locke hath nothing more to add, but that if the idea of extension is so peculiar that it cannot ex. actly agree with the definition that he has given of those simple ideas, so that it differs in some manner from all others of that kind, he thinks it is better to leave it there exposed to this difficulty, than to make a new division in his favour. It is enough for Mr. Locke that his meaning om be understood. It is very common to observe intelligible discour * spoiled hy too much subtilty in nice divisions. We ought to put things together as well as we can, doctrinæ causâ ; but, after all, several things will not be bundled up together under our terins and ways of speaking.



extension, and duration, are made up, and into which they can again be distinctly resolved. Such a small part of duration may be called a moment, and is the time of one idea in our minds in the train of their ordinary succession there. The other, wanting a proper name, I know not whether I may be allowed to call a sensible point, meaning thereby the least particle of matter or space we can discern, which is ordinarily about a minute, and to the sharpest eyes seldom less than thirty seconds of a circle, whereof the eye is the centre.

§. 10. Expansion and duration have this Their parts farther agreement, that though they are both infeparable. considered by us as having parts, yet their parts are not separable one from another, no not even in thought : though the parts of bodies from whence we take our measure of the one, and the parts of motion, or rather the succession of ideas in our ininds, from whence we take the measure of the other, may be interrupted and separated; as the one is often by rest, and the other is by sleep, which we call rest too.

$. 11. But there is this manifest dif- Duration is ference between them, that the ideas of as a line, ex

pansion as a length, which we have of expansion, are

solid. turned every way, and so make figure, and breadth, and thickness; but duration is but as it were the length of one straight line, extended in infinitum,, ac not capable of multiplicity, variation, or figure ; but is one common measure of all existence whatsoever, wherein all things, whilst they exist, equally partake. For this present moment is common to all things that are now in being, and equally comprehends that part of their existence, as much as if they were all but one single being ; and we may truly say, they all exist in the same inoment of time. Whether angels and spirits have any analogy to this, in respect to expansion, is beyond my comprehension: and perhaps for us, who have understandings and comprehensions suited to our own preservation, and the ends of our own being, but not to the reality and extent of all other beings; it is near as hard to conceive any existence, or tờ have an idea of any real being, with a perfect negation of all manner of expan

sion; as it is to have the idea of any real existence, with a perfect negation of all manner of duration; and therefore what spirits have to do with space, or how they communicate in it, we know not. All that we know is, that bodies do each singly possess its proper portion of it, according to the extent of solid parts; and thereby exciude all other bodies from having any share in that particular portion of space, whilst it remains there. Duration has §. 12. Duration, and time which is a part

of it, is the idea we have of perishing disparts toge- tance, of which no two parts exist together, expan- ther, but follow each other in succession; sion all 10gether. as expansion is the idea of lasting distance,

all whose parts exist together, and are not capable of succession. And therefore though we cannot conceive any duration without succession, nor can put it together in our thoughts, that any being does now exist to-morrow, or possess at once more than the present moment of duration ; yet we can conceive the eternal duration of the Almighty far difierent from that of man, or any other finite being. Because man comprehends not in his knowledge, or power, all past and future things ; his thoughts are but of yesterday, and he knows not what to-morrow will bring forth. What is once past he can never recall; and what is yet to come he cannot make present. What I say of man I say of all finite beings; who, though they may far exceed man in knowledge and power, yet are no more than the meanest creature, in comparison with God himself. Finite of any magnitude holds not any proportion to infinite. God's infinite duration being accompanied with infinite knowledge, and infinite power, he sees all things past and to come; and they are no more distant from his knowledge, no farther removed from his sight, than the present: they all lie under the same view; and there is nothing which he cannot make exist each moment he pleases. For the existence of all things depending upon hi, good-pleasure, all things exist every moment that be thinks fit to have them exist. To conclude, expansion and duration do mutually enibrace and comprehend each other; every part of space being in every part of du
