Rh To see two objects at once, is not to see their relations to each other, nor to judge of their difference; as to see many objects, though distinct from one another, is not to reckon their number. I may possibly have in my mind the ideas of a large stick and a small one, without comparing those ideas together, or judging that one is less than the other; as I may look at my hand without counting my fingers. The comparative ideas of greater and less, as well as numerical ideas of one, two, etc., are certainly not sensations, although the understanding produces them only from our sensations.

It has been pretended that sensitive beings distinguish sensations one from the other, by the actual difference there is between those sensations: this, however, demands an explanation. When such sensations are different, a sensitive being is supposed to distinguish them by their difference; but when they are alike, they can then only distinguish them because they perceive one without the other; for, otherwise, how can two objects exactly alike be distinguished in a simultaneous sensation? Such objects must necessarily be blended together and taken for one and the same; particularly according to that system of philosophy in which it is pretended that the sensations, representative of extension, are not extended.

When two comparative sensations are perceived, they make both a joint and separate impression; but their relation to each other is not necessarily perceived in consequence of either. If the judgment we form of this relation were indeed a mere sensation, excited
