‘one’) and a void. For (suppose that the universe is discretes-in-contact. Then), if it is divisible through and through, there is no ‘one’, and therefore no ‘many’ either, but the Whole is void; while to maintain that it is divisible at some points, but not at others, looks like an arbitrary fiction. For up to what limit is it divisible? And for what reason is part of the Whole indivisible, i.e. a plenum, and part divided? Further, they maintain, it is equally necessary to deny the existence of motion. Reasoning in this way, therefore, they were led to transcend sense- perception, and to disregard it on the ground that ‘one ought to follow the argument’: and so they assert that the universe is ‘one’ and immovable. Some of them add that it is ‘infinite’, since the limit (if it had one) would be a limit against the void. There were, then, certain thinkers who, for the reasons we have stated, enunciated views of this kind as their theory of ‘The Truth’… . Moreover, although these opinions appear to follow logically in a dialectical discussion, yet to believe them seems next door to madness when one considers the facts. For indeed no lunatic seems to be so far out of his senses as to suppose that fire and ice are ‘one’: it is only between what is right and what seems right from habit, that some people are mad enough to see no difference. Leucippus, however, thought he had a theory which harmonized with sense-perception and would not abolish either coming-to-be and passing- away or motion and the multiplicity of things. He made these concessions to the facts of perception: on the other hand, he conceded to the Monists that there could be no motion without a void. The result is a theory which he states as follows: ‘The void is a “not being”, and no part of “what is” is a “not- being”; for what “is” in the strict sense of the term is an absolute plenum. This plenum, however, is not “one”: on the contrary, it is a many” infinite in number and invisible owing to the minuteness of their bulk. The “many” move in the void (for there is a void): and by coming together they produce “coming to-be”, while by separating they produce “passing-away”. Moreover, they act and suffer action wherever they chance to be in contact (for there they are not “one”), and they generate by being put together and becoming intertwined. From the genuinely-one, on the other hand, there never could have come-to-be a multiplicity, nor from the genuinely-many a “one”: that is impossible. But’ (just as Empedocles and some of the other philosophers say that things suffer action through their pores, so) ‘all “alteration” and all “passion” take place in the way that has been explained: breaking-up (i.e. passing-away) is effected by means of the void, and so too is growth-solids creeping in to fill the void places.’ Empedocles too is practically bound to adopt the same theory as Leucippus. For he must say that there are certain 676
