While this is a specimen of the critical side of rationalism, its dogmatic side varied from natural ethics to a kind of Socinianism. But in all alike, as its name would imply, it not only asserted that there is only one universal revelation, which takes place through observation of nature and man's reason; but that Christianity was not designed to teach any mysterious truths, but only to confirm the religious teaching of reason; and that no one ought to recognise as true that which cannot be proved to him rationally. The doctrine of a Trinity was necessarily disbelieved; the death of Christ regarded as an historic event, or a symbol that sacrifices were abolished. Holiness was reduced to morality. Extreme veneration for the Bible was called Bibliolatry.[726] Religion was represented as acting by natural motives: the ethical superseded the historic. The early theologians of this dogmatic branch of the [pg 234] school are now little known; but we may name Bretschneider[727] as the type of the least heretical portion of it at the close of this period, who believed Christianity to be a republication of natural religion, supernatural but reasonable: and, as the literary tendency of this school continued to exist in Röhr,[728] after the movement had become extinct in other minds, so Wegscheider,[729] until a recent period, was the solitary instance of the dogmatic position slightly modified.
This completes the history of the first of the three movements, the destructive action of rationalism. The most flourishing period of this form of it was about the beginning of the present century. We have seen it originating in the rational tone of Wolff's philosophy, and the well-meant but ill-judged exegesis which Semler exhibited under the pressure of sceptical difficulties. Stimulated by critical investigations, and by the strong wish which operated on our own theologians, to find the cause of everything, its adherents were led into a [pg 235] disbelief of the supernatural, and ended in explaining away the miraculous, and reducing Christianity to natural religion. The movement, it will be observed, was professedly not intended to be destructive of Christianity. Instead of being inimical, it originated with the clergy, and aimed at harmonizing Christianity with reason. But it contained its own death. The negative criticism is essentially temporary.
The activity of thought was already producing change. We have previously stated that even the Kantian philosophy itself, though at first stimulating the appeal to reason, fostered a deeper perception of duty, and thus prepared the way for a moral reawakening.[730]
We shall accordingly now proceed to state the causes which introduced new elements into the current of public thought; and then describe the gradual progress of the reactionary movement which ensued from them.
Four causes are usually assigned. The first of them was the introduction of new systems of speculative philosophy.
It is not unusual, in those who have no taste for speculation, and who understand only the prosaic, though in some respects the truer, philosophy of Scotland, to despise the great systems of German speculation. Yet, if the series be measured as an example of the power of the human mind, whatever may be the opinion formed in respect to its correctness, it stands among the most interesting efforts of thought. Though the writers can be matched by isolated examples in former ages, perhaps no series of writers exists, hardly even the Greek, certainly not the Neo-Platonist nor the Cartesian, which, in far-reaching penetration, in minuteness of analysis, in brilliancy of imagination, in loftiness of genius, in poetry of expression, in grasp of intellect, in influence on every branch of thought or life, approximates to the series of illustrious thinkers which [pg 236] commenced with Kant and ended with Hegel.[731] The two philosophers at this time whose teaching formed a new influence, were Fichte[732] and Jacobi.[733] Details in reference to their systems must be sought elsewhere.[734] It is only possible here to indicate their central thought, in order to notice their effects on theological inquiry.
We have seen that Kant had reconsidered the great problem, commenced by Descartes and Locke, concerning the ground of certitude, and the nature of knowledge; and had revolutionised philosophy, by attributing to the natural structure of the mind many of those ideas which had usually been supposed to be derived from experience. In his system he had left two elements, a formal and a material; the formal, or innate forms, through which the mind gains knowledge, and the material, presented from external sources. It was the former or ideal element which was examined by Fichte; the latter by Jacobi.
Fichte began to teach at Jena soon after 1790. Grasping firmly Descartes' principle, “Cogito, ergo sum,” he conceived that, as we can only know ourselves, there is no proof that the datum supposed to be external is anything but a form of our own consciousness; and thus he arrived at a subjective idealism not unlike that of bishop Berkeley.[735] Under his view God was only an idea or form of thought; a regulative principle of human belief, the moral order of which the [pg 237] mind was conscious in the universe; and, as atheism was suspected to follow as an inference from his views, he became the subject of persecution. But the instincts of the heart, as well as the arguments of the understanding, were too potent for him; and when he had thus as it were shut up man within the circle of his own finite self, he strove to find a logical passage into a knowledge of the infinite by a principle analogous to that of Spinoza; viz. by regarding both self and the outer world, the subjective and objective, to be identified in some absolute self-existence, of which they were respectively phases.[736]
This aim was only partially effected by Fichte, and was completed by his distinguished successor, Schelling.[737] Schelling saw that the subjective tendency had been pushed too far; and, relying on the spiritual sense through which men of all ages have conceived that they saw the infinite, the reality of which accordingly seems to be attested by a universal induction, he tried to grasp the idea of the self-existent One, who is the one absolute Reality, the one eternal Being, the eternal Source from which all other light is derived, and from which all things develope. “Intellectual intuition” he thought to be the means by which we have this knowledge of the infinite, and are able to trace the development of it into its limitations in nature and in the mind. The method is analogous to that of Spinoza, save that the infinite is studied dynamically instead of mechanically, as a movement not a substance, in time not in space.
The roll of these great thinkers, whose speculations were suggested by the formal side of Kant's philosophy, is not yet full. But the two which have been named wrote and affected thought, the one before, the other soon after, the commencement of the present century. Hegel followed in the same track, but influenced [pg 238] thought at a later period.[738] He too aimed at solving the same problem as Schelling: he too sought to transcend the conditions of object and subject which limit thought; but it was by assuming a representative or mediate faculty that transcends consciousness, and not, as Schelling, an intuitional or presentative.[739]
