everything can ‘combine’ with everything. On the contrary, both of the constituents that are combined in the compound must originally have existed in separation: but no property can have separate existence.) Since, however, some things are-potentially while others are-actually, the constituents combined in a compound can ‘be’ in a sense and yet ‘not-be’. The compound may he-actually other than the constituents from which it has resulted; nevertheless each of them may still he-potentially what it was before they were combined, and both of them may survive undestroyed. (For this was the difficulty that emerged in the previous argument: and it is evident that the combining constituents not only coalesce, having formerly existed in separation, but also can again be separated out from the compound.) The constituents, therefore, neither (a) persist actually, as ‘body’ and ‘white’ persist: nor (b) are they destroyed (either one of them or both), for their ‘power of action’ is preserved. Hence these difficulties may be dismissed: but the problem immediately connected with them-whether combination is something relative to perception’ must be set out and discussed. When the combining constituents have been divided into parts so small, and have been juxtaposed in such a manner, that perception fails to discriminate them one from another, have they then ‘been combined Or ought we to say ‘No, not until any and every part of one constituent is juxtaposed to a part of the other’? The term, no doubt, is applied in the former sense: we speak, e.g. of wheat having been ‘combined’ with barley when each grain of the one is juxtaposed to a grain of the other. But every body is divisible and therefore, since body ‘combined’ with body is uniform in texture throughout, any and every part of each constituent ought to be juxtaposed to a part of the other. No body, however, can be divided into its ‘least’ parts: and ‘composition’ is not identical with ‘combination’, but other than it. From these premises it clearly follows (i) that so long as the constituents are preserved in small particles, we must not speak of them as ‘combined’. (For this will be a ‘composition’ instead of a ‘blending’ or ‘combination’: nor will every portion of the resultant exhibit the same ratio between its constituents as the whole. But we maintain that, if ‘combination’ has taken place, the compound must be uniform in texture throughout-any part of such a compound being the same as the whole, just as any part of water is water: whereas, if ‘combination’ is ‘composition of the small particles’, nothing of the kind will happen. On the contrary, the constituents will only be ‘combined’ relatively to perception: and the same thing will be ‘combined’ to one percipient, if his sight is not sharp, (but not to another,) while to the eye of Lynceus nothing will be ‘combined’.) It clearly follows (ii) that we must not speak of the constituents as ‘combined 682
