THREE:The sergeant in charge of the party had heard all about that.We cannot, then, agree with those critics who attribute to Aristotle a recognition of such things as laws of nature, in the sense of uniform co-existences and sequences.279 Such an idea implies a certain balance and equality between subject and predicate which he would never have admitted. It would, in his own language, be making relation, instead of substance, the leading category. It must be remembered also that he did not acknowledge the existence of those constant conjunctions in Nature which we call laws. He did not admit that all matter was heavy, or that fluidity implied the presence of heat. The possession of constant properties, or rather of a single constant propertycircular rotationis reserved for the aether. Nor is this a common property of different and indefinitely multipliable phenomena; it characterises a single body, measurable in extent and unique in kind. Moreover,386 we have something better than indirect evidence on this point; we have the plain statement of Aristotle himself, that all science depends on first principles, about which it is impossible to be mistaken, precisely because they are universal abstractions not presented to the mind by any combination,280a view quite inconsistent with the priority now given to general laws.
