Usually the question is wrongly stated. The point here is not about a Christianity arbitrarily fashioned, but only about Catholic Christianity and Catholic theology. This conquered Neoplatonism after it had a.s.similated nearly everything it possessed. Further, we must note the place where the victory was gained. The battle-field was the empire of Constantine, Theodosius and Justinian. Only when we have considered these and all other conditions, are we ent.i.tled to enquire in what degree the specific doctrines of Christianity contributed to the victory, and what share the organisation of the church had in it.
Undoubtedly, however, we must always give the chief prominence to the fact that the Catholic dogmatic excluded polytheism in principle, and at the same time found a means by which it could represent the faith of the cultured mediated by science as identical with the faith of the mult.i.tude resting on authority.
In the theology and philosophy of the middle ages, mysticism was the strong opponent of rationalistic dogmatism; and, in fact, Platonism and Neoplatonism were the sources from which in the age of the Renaissance and in the following two centuries, empiric science developed itself in opposition to the rationalistic dogmatism which disregarded experience.
Magic, astrology, alchemy, all of which were closely connected with Neoplatonism, gave an effective impulse to the observation of nature and, consequently, to natural science, and finally prevailed over formal and barren rationalism Consequently, in the history of science, Neoplatonism has attained a significance and performed services of which men like Iamblichus and Proclus never ventured to dream. In point of fact, actual history is often more wonderful and capricious than legends and fables.

[Footnote 455: Excellent remarks on the nature of Neoplatonism may be found in Eucken, Gott. Gel. Anz., 1 Marz, 1884 p. 176 ff.: this sketch was already written before I saw them. "We find the characteristic of the Neoplatonic epoch in the effort to make the inward, which till then had had alongside of it an independent outer world as a contrast, the exclusive and all-determining element. The movement which makes itself felt here, outlasts antiquity and prepares the way for the modern period; it brings about the dissolution of that which marked the culminating point of ancient life, that which we are wont to call specifically cla.s.sic. The life of the spirit, till then conceived as a member of an ordered world and subject to its laws, now freely pa.s.ses beyond these bounds, and attempts to mould, and even to create, the universe from itself. No doubt the different attempts to realise this desire reveal, for the most part, a deep gulf between will and deed; usually ethical and religious requirements of the naive human consciousness must replace universally creative spiritual power, but all the insufficient and unsatisfactory elements of this period should not obscure the fact that, in one instance, it reached the height of a great philosophic achievement, in the case of Plotinus."]
[Footnote 456: Plotinus, even in his lifetime, was reproached with having borrowed most of his system from Numenius. Porphyry, in his "Vita Plotini", defended him against this reproach.]
