be reckoned its active Powers and passive Capacities which though not strictly simple Ideas yet in this respect for brevities sake may conveniently enough be reckoned amongst them Thus the power of drawing Iron is one of the Ideas of the Complex one of that substance we call a Load-stone and a Power to be so drawn is a part of the Complex one we call Iron which Powers pass for inherent Qualities in those Subjects Because every Substance being as apt by the Powers we observe in it to change some sensible Qualities in other Subjects as it is to produce in us those simple Ideas we receive immediately from it does by those new sensible Qualities introduced into other Subjects discover to us those Powers which do thereby mediately affect our Senses as regularly as its sensible Qualities do it immediately v. g. we immediately by our Senses perceive in Fire its Heat and Colour which are if rightly considered nothing but Powers in it to produce those Ideas in us We also by our Senses perceive the colour and brittleness of Charcoal whereby we come by the Knowledge of another Power in Fire which it has to change the colour and consistency of Wood By the former Fire immediately by the later it mediately discovers to us these several Powers which therefore we look upon to be a part of the Qualities of Fire and so make them a part of the complex Ideas of it For all those Powers that we take Cognizance of terminating only in the alteration of some sensible Qualities in those Subjects on which they operate and so making them exhibit to us new sensible Ideas therefore it is that I have reckoned these Powers amongst the simple Ideas which make the complex ones of the sorts of Substances though these Powers considered in themselves are truly complex Ideas And in this looser sense I crave leave to be understood when I name any of these Potentialities amongst the simple Ideas which we recollect in our Minds when we think of particular Substances For the Powers that are severally in them are necessary to be considered if we will have true distinct Notions of Substances § 8. Nor are we to wonder that Powers make a great part of our complex Ideas of Substances since their secondary Qualities are those which in most of them serve principally to distinguish Substances one from another and commonly make a considerable part of the complex Idea of the several sorts of them For our Senses failing us in the discovery of the Bulk Texture and Figure of the minute parts of Bodies on which their real Constitutions and Differences depend we are fain to make use of their secondary Qualities as the characteristical Notes and Marks whereby to frame Ideas of them in our Minds and distinguish them one from another All which secondary Qualities as has been shewn are nothing but bare Powers For the Colour and Taste of Opium are as well as its foporifick or anodyn Virtues meer Powers depending on its primary Qualities whereby it is sitted to produce different Operations on different parts of our Bodies The Ideas that make our complex ones of corporeal Substances are of these three sorts First The Ideas of the primary Qualities of things which are discovered by our Senses and are in them even when we perceive them not such are the Bulk Figure Number Situation and Motion of the Parts of Bodies which are really in them whether we perceive them or no. Secondly The sensible secondary Qualities which depending on these are nothing but the Powers those Substances have to produce several Ideas in us by our Senses which Ideas are not in the things themselves otherwise than as any thing is in its Cause Thirdly The aptness we consider in any Substance to give or receive such alterations of primary Qualities as that the Substance so altered should produce in us different Ideas from what it did before these are called active and passive Powers all which Powers as far as we have any Notice or Notion of them terminate only in sensible simple Ideas for whatever alteration a Load-stone has the Power to make in the minute Particles of Iron we should have no Notion of any Power it had at all to operate on Iron did not its sensible Motion discover it and I doubt not but there are a thousand Changes that Bodies we daily handle have a Power to cause in one another which we never suspect because they never appear in sensible effects § 10. Powers therefore justly make a great part of our complex Ideas of Substances He that will examine his complex Idea of Gold will find several of its Ideas that make it up to be only Powers as the Power of being melted but of keeping its weight in the Fire of being dissolved in Aq. Regia are Ideas as necessary to make up our complex Idea of Gold as its Colour and Weight which if duly considered are also nothing but different Powers For to speak truly Yellowness is not actually in Gold but is a Power in Gold to produce that Idea in us by our Eyes when placed in a due Light and the Heat which we cannot leave out of our Idea of the Sun is no more really in the Sun than the white Colour it introduces in Wax These are both equally Powers in the Sun operating by the Motion and Figure of its insensible Parts so on a Man as to make him have the Idea of Heat and so on Wax as to make it capable to produce in a Man the Idea of White § 11. Had we Senses acute enough to discern the minute particles of Bodies and the real Constitution on which their sensible Qualities depend I doubt not but they would produce quite different Ideas in us and that which is now the yellow Colour of Gold would then disappear and instead of it we should see an admirable Texture of parts of a certain Size and Figure This Microscopes plainly discover to us for what to our naked Eyes produces a certain Colour is by thus augmenting the acuteness of our Senses discovered to be quite a different thing and the thus altering as it were the proportion of the Bulk of the minute parts of a coloured Object to our usual Sight produces different Ideas from what it did before Thus Sand or pounded Glass which is opaque and white to the naked Eye is pellucid in a Microscope and a Hair seen this way looses its former Colour and is in a great measure pellucid with a mixture of some bright sparkling Colours such as appear from the refraction of Diamonds and other pellucid Bodies Blood to the naked Eye appears all red but by a good Microscope wherein its lesser parts appear shews only some few Globules of Red swimming in a pellucid Liquor and how these red Globules would appear if Glasses could be found that yet could magnifie them 1000 or 10000 times more is uncertain § 12.
