TWO: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.The truth is that critics seem to have been misled by a superficial analogy between the spiritualistic revival accomplished by Plotinus, and the Romantic revival which marked the beginning of the present century. The two movements have, no doubt, several traits in common; but there is this great difference between them, that the latter was, what the former was not, a reaction against individualism, agnosticism, and religious unbelief. The right analogy will be found not by looking forward but by looking back. It will then be seen that the Neo-Platonists were what their traditional name implies, disciples of Plato, and not only of Plato but of194 Aristotle as well. They stood in the same relation to the systems which they opposed as that in which the two great founders of spiritualism had stood to the naturalistic and humanist schools of their timeof course with whatever modifications of a common standpoint were necessitated by the substitution of a declining for a progressive civilisation. Like Plato also, they were profoundly influenced by the Pythagorean philosophy, with its curious combination of mystical asceticism and mathematics. And, to complete the analogy, they too found themselves in presence of a powerful religious reaction, against the excesses of which, like him, they at first protested, although with less than his authority, and only, like him, to be at last carried away by its resistless torrent. It is to the study of this religious movement that we must now address ourselves, before entering on an examination of the latest form assumed by Greek philosophy among the Greeks themselves.
