by those who maintain a theory like that of Empedocles? They must conceive it as composition-just as a wall comes-to-be out of bricks and stones: and the ‘Mixture’, of which they speak, will be composed of the ‘elements’, these being preserved in it unaltered but with their small particles juxtaposed each to each. That will be the manner, presumably, in which flesh and every other compound results from the ‘elements’. Consequently, it follows that Fire and Water do not come-to-be ‘out of any and every part of flesh’. For instance, although a sphere might come-to-be out of this part of a lump of wax and a pyramid out of some other part, it was nevertheless possible for either figure to have come-to-be out of either part indifferently: that is the manner of coming-to-be when ‘both Fire and Water come-to-be out of any and every part of flesh’. Those, however, who maintain the theory in question, are not at liberty to conceive that ‘both come-to-be out of flesh’ in that manner, but only as a stone and a brick ‘both come-to-be out of a wall’-viz. each out of a different place or part. Similarly (b) even for those who postulate a single matter of their ‘elements’ there is a certain difficulty in explaining how anything is to result from two of them taken together-e.g. from ‘cold’ and hot’, or from Fire and Earth. For if flesh consists of both and is neither of them, nor again is a ‘composition’ of them in which they are preserved unaltered, what alternative is left except to identify the resultant of the two ‘elements’ with their matter? For the passingaway of either ‘element’ produces either the other or the matter. Perhaps we may suggest the following solution. (i) There are differences of degree in hot and cold. Although, therefore, when either is fully real without qualification, the other will exist potentially; yet, when neither exists in the full completeness of its being, but both by combining destroy one another’s excesses so that there exist instead a hot which (for a ‘hot’) is cold and a cold which (for a ‘cold’) is hot; then what results from these two contraries will be neither their matter, nor either of them existing in its full reality without qualification. There will result instead an ‘intermediate’: and this ‘intermediate’, according as it is potentially more hot than cold or vice versa, will possess a power-of-heating that is double or triple its power-of-cooling, or otherwise related thereto in some similar ratio. Thus all the other bodies will result from the contraries, or rather from the ‘elements’, in so far as these have been ‘combined’: while the elements’ will result from the contraries, in so far as these ‘exist potentially’ in a special sense-not as matter ‘exists potentially’, but in the sense explained above. And when a thing comes-to-be in this manner, the process is cobination’; whereas what comes-to-be in the other manner is matter. Moreover (ii) contraries also ‘suffer action’, in accordance with the disjunctively-articulated definition established in the early part of this work.’ For the actually-hot is potentially-cold and the 697
