HYL. Let me think a little—I do not find that I can.

PHIL. And can you think it possible that should really exist in nature which implies a repugnancy in its conception?

HYL. By no means.

PHIL. Since therefore it is impossible even for the mind to disunite the ideas of extension and motion from all other sensible qualities, doth it not follow, that where the one exist there necessarily the other exist likewise?

HYL. It should seem so.

PHIL. Consequently, the very same arguments which you admitted as conclusive against the Secondary Qualities are, without any farther application of force, against the Primary too. Besides, if you will trust your senses, is it not plain all sensible qualities coexist, or to them appear as being in the same place? Do they ever represent a motion, or figure, as being divested of all other visible and tangible qualities?

HYL. You need say no more on this head. I am free to own, if there be no secret error or oversight in our proceedings hitherto, that all sensible qualities are alike to be denied existence without the mind. But, my fear is that I have been too liberal in my former concessions, or overlooked some fallacy or other. In short, I did not take time to think.

PHIL. For that matter, Hylas, you may take what time you please in reviewing the progress of our inquiry. You are at liberty to recover any slips you might have made, or offer whatever you have omitted which makes for your first opinion.

HYL. One great oversight I take to be this—that I did not sufficiently distinguish the OBJECT from the SENSATION. Now, though this latter may not exist without the mind, yet it will not thence follow that the former cannot.

PHIL. What object do you mean? the object of the senses?

HYL. The same.

PHIL. It is then immediately perceived?

HYL. Right.

PHIL. Make me to understand the difference between what is immediately perceived and a sensation.

HYL. The sensation I take to be an act of the mind perceiving; besides which, there is something perceived; and this I call the OBJECT. For example, there is red and yellow on that tulip. But then the act of perceiving those colours is in me only, and not in the tulip.

PHIL. What tulip do you speak of? Is it that which you see?

HYL. The same.

PHIL. And what do you see beside colour, figure, and extension?

HYL. Nothing.

PHIL. What you would say then is that the red and yellow are coexistent with the extension; is it not?

HYL. That is not all; I would say they have a real existence without the mind, in some unthinking substance.

PHIL. That the colours are really in the tulip which I see is manifest. Neither can it be denied that this tulip may exist independent of your mind or mine; but, that any immediate object of the senses,—that is, any idea, or combination of ideas—should exist in an unthinking substance, or exterior to ALL minds, is in itself an evident contradiction. Nor can I imagine how this follows from what you said just now, to wit, that the red and yellow were on the tulip you SAW, since you do not pretend to SEE that unthinking substance.

HYL. You have an artful way, Philonous, of diverting our inquiry from the subject.

PHIL. I see you have no mind to be pressed that way. To return then to your distinction between SENSATION and OBJECT; if I take you right, you distinguish in every perception two things, the one an action of the mind, the other not.

HYL. True.

PHIL. And this action cannot exist in, or belong to, any unthinking thing; but, whatever beside is implied in a perception may?

HYL. That is my meaning.

PHIL. So that if there was a perception without any act of the mind, it were possible such a perception should exist in an unthinking substance?

HYL. I grant it. But it is impossible there should be such a perception.

PHIL. When is the mind said to be active?

HYL. When it produces, puts an end to, or changes, anything.

PHIL. Can the mind produce, discontinue, or change anything, but by an act of the will?

HYL. It cannot.

PHIL. The mind therefore is to be accounted ACTIVE in its perceptions so far forth as VOLITION is included in them?

HYL. It is.

PHIL. In plucking this flower I am active; because I do it by the motion of my hand, which was consequent upon my volition; so likewise in applying it to my nose. But is either of these smelling?

HYL. NO.

PHIL. I act too in drawing the air through my nose; because my breathing so rather than otherwise is the effect of my volition. But neither can this be called SMELLING: for, if it were, I should smell every time I breathed in that manner?

HYL. True.

PHIL. Smelling then is somewhat consequent to all this?

HYL. It is.

PHIL. But I do not find my will concerned any farther. Whatever more there is—as that I perceive such a particular smell, or any smell at all—this is independent of my will, and therein I am altogether passive. Do you find it otherwise with you, Hylas?

HYL. No, the very same.

PHIL. Then, as to seeing, is it not in your power to open your eyes, or keep them shut; to turn them this or that way?

HYL. Without doubt.

PHIL. But, doth it in like manner depend on YOUR will that in looking on this flower you perceive WHITE rather than any other colour? Or, directing your open eyes towards yonder part of the heaven, can you avoid seeing the sun? Or is light or darkness the effect of your volition?

HYL. No, certainly.

PHIL. You are then in these respects altogether passive? HYL. I am.

PHIL. Tell me now, whether SEEING consists in perceiving light and colours, or in opening and turning the eyes?

HYL. Without doubt, in the former.

PHIL. Since therefore you are in the very perception of light and colours altogether passive, what is become of that action you were speaking of as an ingredient in every sensation? And, doth it not follow from your own concessions, that the perception of light and colours, including no action in it, may exist in an unperceiving substance? And is not this a plain contradiction?

HYL. I know not what to think of it.

PHIL. Besides, since you distinguish the ACTIVE and PASSIVE in every perception, you must do it in that of pain. But how is it possible that pain, be it as little active as you please, should exist in an unperceiving substance? In short, do but consider the point, and then confess ingenuously, whether light and colours, tastes, sounds, &c. are not all equally passions or sensations in the soul. You may indeed call them EXTERNAL OBJECTS, and give them in words what subsistence you please. But, examine your own thoughts, and then tell me whether it be not as I say?
