PHIL. How can you then conclude from sight that figures exist without, when you acknowledge colours do not; the sensible appearance being the very same with regard to both?

HYL. I know not what to answer.

PHIL. But, allowing that distance was truly and immediately perceived by the mind, yet it would not thence follow it existed out of the mind.

For, whatever is immediately perceived is an idea: and can any idea exist out of the mind?

HYL. To suppose that were absurd: but, inform me, Philonous, can we perceive or know nothing beside our ideas?

PHIL. As for the rational deducing of causes from effects, that is beside our inquiry. And, by the senses you can best tell whether you perceive anything which is not immediately perceived. And I ask you, whether the things immediately perceived are other than your own sensations or ideas? You have indeed more than once, in the course of this conversation, declared yourself on those points; but you seem, by this last question, to have departed from what you then thought.

HYL. To speak the truth, Philonous, I think there are two kinds of objects:--the one perceived immediately, which are likewise called IDEAS; the other are real things or external objects, perceived by the mediation of ideas, which are their images and representations. Now, I own ideas do not exist without the mind; but the latter sort of objects do. I am sorry I did not think of this distinction sooner; it would probably have cut short your discourse.

PHIL. Are those external objects perceived by sense or by some other faculty?

HYL. They are perceived by sense.

PHIL. Howl Is there any thing perceived by sense which is not immediately perceived?

HYL. Yes, Philonous, in some sort there is. For example, when I look on a picture or statue of Julius Caesar, I may be said after a manner to perceive him (though not immediately) by my senses.

PHIL. It seems then you will have our ideas, which alone are immediately perceived, to be pictures of external things: and that these also are perceived by sense, inasmuch as they have a conformity or resemblance to our ideas?

HYL. That is my meaning.

PHIL. And, in the same way that Julius Caesar, in himself invisible, is nevertheless perceived by sight; real things, in themselves imperceptible, are perceived by sense.

HYL. In the very same.

PHIL. Tell me, Hylas, when you behold the picture of Julius Caesar, do you see with your eyes any more than some colours and figures, with a certain symmetry and composition of the whole?

HYL. Nothing else.

PHIL. And would not a man who had never known anything of Julius Caesar see as much?

HYL. He would.

PHIL. Consequently he hath his sight, and the use of it, in as perfect a degree as you?

HYL. I agree with you.

PHIL. Whence comes it then that your thoughts are directed to the Roman emperor, and his are not? This cannot proceed from the sensations or ideas of sense by you then perceived; since you acknowledge you have no advantage over him in that respect. It should seem therefore to proceed from reason and memory: should it not?

HYL. It should.

PHIL. Consequently, it will not follow from that instance that anything is perceived by sense which is not, immediately perceived. Though I grant we may, in one acceptation, be said to perceive sensible things mediately by sense: that is, when, from a frequently perceived connexion, the immediate perception of ideas by one sense SUGGESTS to the mind others, perhaps belonging to another sense, which are wont to be connected with them. For instance, when I hear a coach drive along the streets, immediately I perceive only the sound; but, from the experience I have had that such a sound is connected with a coach, I am said to hear the coach. It is nevertheless evident that, in truth and strictness, nothing can be HEARD BUT SOUND; and the coach is not then properly perceived by sense, but suggested from experience. So likewise when we are said to see a red-hot bar of iron; the solidity and heat of the iron are not the objects of sight, but suggested to the imagination by the colour and figure which are properly perceived by that sense. In short, those things alone are actually and strictly perceived by any sense, which would have been perceived in case that same sense had then been first conferred on us. As for other things, it is plain they are only suggested to the mind by experience, grounded on former perceptions. But, to return to your comparison of Caesar"s picture, it is plain, if you keep to that, you must hold the real things, or archetypes of our ideas, are not perceived by sense, but by some internal faculty of the soul, as reason or memory.

I would therefore fain know what arguments you can draw from reason for the existence of what you call REAL THINGS OR MATERIAL OBJECTS. Or, whether you remember to have seen them formerly as they are in themselves; or, if you have heard or read of any one that did.

HYL. I see, Philonous, you are disposed to raillery; but that will never convince me.

PHIL. My aim is only to learn from you the way to come at the knowledge of MATERIAL BEINGS. Whatever we perceive is perceived immediately or mediately: by sense, or by reason and reflexion. But, as you have excluded sense, pray shew me what reason you have to believe their existence; or what MEDIUM you can possibly make use of to prove it, either to mine or your own understanding.

HYL. To deal ingenuously, Philonous, now I consider the point, I do not find I can give you any good reason for it. But, thus much seems pretty plain, that it is at least possible such things may really exist. And, as long as there is no absurdity in supposing them, I am resolved to believe as I did, till you bring good reasons to the contrary.

PHIL. What! Is it come to this, that you only BELIEVE the existence of material objects, and that your belief is founded barely on the possibility of its being true? Then you will have me bring reasons against it: though another would think it reasonable the proof should lie on him who holds the affirmative. And, after all, this very point which you are now resolved to maintain, without any reason, is in effect what you have more than once during this discourse seen good reason to give up. But, to pa.s.s over all this; if I understand you rightly, you say our ideas do not exist without the mind, but that they are copies, images, or representations, of certain originals that do?

HYL. You take me right.

PHIL. They are then like external things?

HYL. They are.

PHIL. Have those things a stable and permanent nature, independent of our senses; or are they in a perpetual change, upon our producing any motions in our bodies--suspending, exerting, or altering, our faculties or organs of sense?

HYL. Real things, it is plain, have a fixed and real nature, which remains the same notwithstanding any change in our senses, or in the posture and motion of our bodies; which indeed may affect the ideas in our minds, but it were absurd to think they had the same effect on things existing without the mind.

PHIL. How then is it possible that things perpetually fleeting and variable as our ideas should be copies or images of anything fixed and constant? Or, in other words, since all sensible qualities, as size, figure, colour, &c., that is, our ideas, are continually changing, upon every alteration in the distance, medium, or instruments of sensation; how can any determinate material objects be properly represented or painted forth by several distinct things, each of which is so different from and unlike the rest? Or, if you say it resembles some one only of our ideas, how shall we be able to distinguish the true copy from all the false ones?

HYL. I profess, Philonous, I am at a loss. I know not what to say to this.

PHIL. But neither is this all. Which are material objects in themselves--perceptible or imperceptible?

HYL. Properly and immediately nothing can be perceived but ideas. All material things, therefore, are in themselves insensible, and to be perceived only by our ideas.

PHIL. Ideas then are sensible, and their archetypes or originals insensible?

HYL. Right.

PHIL. But how can that which is sensible be like that which is insensible? Can a real thing, in itself INVISIBLE, be like a COLOUR; or a real thing, which is not AUDIBLE, be like a SOUND? In a word, can anything be like a sensation or idea, but another sensation or idea?

HYL. I must own, I think not.

PHIL. Is it possible there should be any doubt on the point? Do you not perfectly know your own ideas?

HYL. I know them perfectly; since what I do not perceive or know can be no part of my idea.

PHIL. Consider, therefore, and examine them, and then tell me if there be anything in them which can exist without the mind: or if you can conceive anything like them existing without the mind.

HYL. Upon inquiry, I find it is impossible for me to conceive or understand how anything but an idea can be like an idea. And it is most evident that NO IDEA CAN EXIST WITHOUT THE MIND.

PHIL. You are therefore, by your principles, forced to deny the REALITY of sensible things; since you made it to consist in an absolute existence exterior to the mind. That is to say, you are a downright sceptic. So I have gained my point, which was to shew your principles led to Scepticism.

HYL. For the present I am, if not entirely convinced, at least silenced.

PHIL. I would fain know what more you would require in order to a perfect conviction. Have you not had the liberty of explaining yourself all manner of ways? Were any little slips in discourse laid hold and insisted on? Or were you not allowed to retract or reinforce anything you had offered, as best served your purpose? Hath not everything you could say been heard and examined with all the fairness imaginable? In a word have you not in every point been convinced out of your own mouth? And, if you can at present discover any flaw in any of your former concessions, or think of any remaining subterfuge, any new distinction, colour, or comment whatsoever, why do you not produce it?

HYL. A little patience, Philonous. I am at present so amazed to see myself ensnared, and as it were imprisoned in the labyrinths you have drawn me into, that on the sudden it cannot be expected I should find my way out. You must give me time to look about me and recollect myself.

PHIL. Hark; is not this the college bell?
