§38But, say you, it sounds very harsh to say we eat and drink ideas, and are clothed with ideas. I acknowledge it does so--the word IDEA not being used in common discourse to signify the several combinations of sensible qualities which are called THINGS; and it is certain that any expression which varies from the familiar use of language will seem harsh and ridiculous. But this doth not concern the truth of the proposition, which in other words is no more than to say, we are fed and clothed with those things which we perceive immediately by our senses. The hardness or softness, the colour, taste, warmth, figure, or suchlike qualities, which combined together constitute the several sorts of victuals and apparel, have been shown to exist only in the mind that perceives them; and this is all that is meant by calling them IDEAS; which word if it was as ordinarily used as THING, would sound no harsher nor more ridiculous than it. I am not for disputing about the propriety, but the truth of the expression. If therefore you agree with me that we eat and drink and are clad with the immediate objects of sense, which cannot exist unperceived or without the mind, I shall readily grant it is more proper or conformable to custom that they should be called things rather than ideas.

§39THE TERM IDEA PREFERABLE TO THING.--If it be demanded why I make use of the word IDEA, and do not rather in compliance with custom call them THINGS. I answer, I do it for two reasons:--first, because the term THING in contra-distinction to IDEA, is generally supposed to denote somewhat existing without the mind; secondly, because THING has a more comprehensive signification than IDEA, including SPIRIT or thinking things as well as IDEAS. Since therefore the objects of sense exist only in the mind, and are withal thoughtless and inactive, I chose to mark them by the word IDEA, which implies those properties.

§40THE EVIDENCE OF THE SENSES NOT DISCREDITED.--But, say what we can, some one perhaps may be apt to reply, he will still believe his senses, and never suffer any arguments, how plausible soever, to prevail over the certainty of them. Be it so; assert the evidence of sense as high as you please, we are willing to do the same. That what I see, hear, and feel DOTH EXIST, THAT IS to say, IS PERCEIVED BY ME, I no more doubt than I do of my own being. But I do not see how the testimony of sense can be alleged as a proof for the existence of anything which is not perceived by sense. We are not for having any man turn SCEPTIC and disbelieve his senses; on the contrary, we give them all the stress and assurance imaginable; nor are there any principles more opposite to Scepticism than those we have laid down [Note.], as shall be hereafter clearly shown.

[Note: They extirpate the very root of scepticism, "the fallacy of the senses."--Ed.]

§41SECOND OBJECTION.--ANSWER.--Secondly, it will be OBJECTED that there is a great difference betwixt real fire for instance, and the idea of fire, betwixt dreaming or imagining oneself burnt, and actually being so: if you suspect it to be only the idea of fire which you see, do but put your hand into it and you will be convinced with a witness. This and the like may be urged in opposition to our tenets. To all which the ANSWER is evident from what has been already said; and I shall only add in this place, that if real fire be very different from the idea of fire, so also is the real pain that it occasions very different from the idea of the same pain, and yet nobody will pretend that real pain either is, or can possibly be, in an unperceiving thing, or without the mind, any more than its idea.

§42THIRD OBJECTION.--ANSWER.--Thirdly, it will be objected that we see things actually without or at distance from us, and which consequently do not exist in the mind; it being absurd that those things which are seen at the distance of several miles should be as near to us as our own thoughts. In answer to this, I desire it may be considered that in a DREAM we do oft perceive things as existing at a great distance off, and yet for all that, those things are acknowledged to have their existence only in the mind.

§43But, for the fuller clearing of this point, it may be worth while to consider how it is that we perceive distance and things placed at a distance by sight. For, that we should in truth see EXTERNAL space, and bodies actually existing in it, some nearer, others farther off, seems to carry with it some opposition to what has been said of their existing nowhere without the mind. The consideration of this difficulty it was that gave birth to my "Essay towards a New Theory of Vision," which was published not long since, wherein it is shown (1) that DISTANCE or outness is NEITHER IMMEDIATELY of itself PERCEIVED by sight, nor yet apprehended or judged of by lines and angles, or anything that has a necessary connexion with it; but (2) that it is ONLY SUGGESTED to our thoughts by certain visible ideas and sensations attending vision, which in their own nature have no manner of similitude or relation either with distance or things placed at a distance; but, by a connexion taught us BY EXPERIENCE, they come to signify and suggest them to us, after the same manner that WORDS of any language suggest the ideas they are made to stand for; insomuch that a man BORN blind and afterwards made to see, would not, at first sight, think the things he saw to be without his mind, or at any distance from him. See sect. 41 of the fore-mentioned treatise.

§44The ideas of sight and touch make two species entirely distinct and heterogeneous. THE FORMER ARE MARKS AND PROGNOSTICS OF THE LATTER. That the proper objects of sight neither exist without mind, nor are the images of external things, was shown even in that treatise. Though throughout the same the contrary be supposed true of tangible objects--not that to suppose that vulgar error was necessary for establishing the notion therein laid down, but because it was beside my purpose to examine and refute it in a discourse concerning VISION. So that in strict truth the ideas of sight, when we apprehend by them distance and things placed at a distance, do not suggest or mark out to us things ACTUALLY existing at a distance, but only admonish us what ideas of touch will be imprinted in our minds at such and such distances of time, and in consequence of such or such actions. It is, I say, evident from what has been said in the foregoing parts of this Treatise, and in sect. 147 and elsewhere of the Essay concerning Vision, that visible ideas are the Language whereby the governing Spirit on whom we depend informs us what tangible ideas he is about to imprint upon us, in case we excite this or that motion in our own bodies. But for a fuller information in this point I refer to the Essay itself.

§45FOURTH OBJECTION, FROM PERPETUAL ANNIHILATION AND CREATION.--ANSWER.--Fourthly, it will be objected that from the foregoing principles it follows things are every moment annihilated and created anew. The objects of sense exist only when they are perceived; the trees therefore are in the garden, or the chairs in the parlour, no longer than while there is somebody by to perceive them. Upon SHUTTING MY EYES all the furniture in the room is reduced to nothing, and barely upon opening them it is again created. In ANSWER to all which, I refer the reader to what has been said in sect. 3, 4, &c., and desire he will consider whether he means anything by the actual existence of an idea distinct from its being perceived. For my part, after the nicest inquiry I could make, I am not able to discover that anything else is meant by those words; and I once more entreat the reader to sound his own thoughts, and not suffer himself to be imposed on by words. If he can conceive it possible either for his ideas or their archetypes to exist without being perceived, then I give up the cause; but if he cannot, he will acknowledge it is unreasonable for him to stand up in defence of he knows not what, and pretend to charge on me as an absurdity the not assenting to those propositions which at bottom have no meaning in them.

§46ARGUMENTUM AD HOMINEM.--It will not be amiss to observe how far the received principles of philosophy are themselves chargeable with those pretended absurdities. (1) It is thought strangely absurd that upon closing my eyelids all the visible objects around me should be reduced to nothing; and yet is not this what philosophers commonly acknowledge, when they agree on all hands that light and colours, which alone are the proper and immediate objects of sight, are mere sensations that exist no longer than they are perceived? (2)Again, it may to some perhaps seem very incredible that things should be every moment creating, yet this very notion is commonly taught in the schools. For the SCHOOLMEN, though they acknowledge the existence of Matter, and that the whole mundane fabric is framed out of it, are nevertheless of opinion that it cannot subsist without the divine conservation, which by them is expounded to be a continual creation.
