Let us, then, consider together how it is attracted. How else than in the way that iron is attracted by the lodestone, the latter having a
faculty1 attractive of this particular quality [existing in iron]? But if the beginning of anadosis depends on the squeezing action of the stomach, and the whole movement thereafter on the peristalsis and
propulsive2 action of the
veins3, as well as on the
traction4 exerted by each of the parts which are undergoing
nourishment5, then we can abandon the principle of
replacement6 of
evacuated7 matter, as not being suitable for a man who assumes Nature to be a skilled artist; thus we shall also have avoided the contradiction of Asclepiades though we cannot refute it: for the disjunctive argument used for the purposes of
demonstration8 is, in reality, disjunctive not of two but of three alternatives; now, if we treat the disjunction as a disjunction of two alternatives, one of the two propositions assumed in constructing our proof must be false; and if as a disjunctive of three alternatives, no conclusion will be arrived at.
