This mode of arguing held good until the time of Kant; and we see in it the endeavour to apprehend the doctrine of the Church through reason. This opposition between Being and thought is the starting point in philosophy, the absolute that contains the two opposites within itself—a conception, according to Spinoza, which involves its existence likewise. Of Anselm it is however to be remarked that the formal logical mode of the understanding, the process of scholastic reasoning is to be found in him, the content indeed is right, but the form faulty. For in the first place the expression “the thought of a Highest” is assumed as the prius. Secondly, there are two sorts of objects of thought—one that is and another that is not; the object that is only thought and does not exist, is as imperfect as that which only is without being thought. The third point is that what is highest must likewise exist. But what is highest, the standard to which all else must conform, must be no mere hypothesis, as we find it represented in the conception of a highest acme of perfection, as a content which is thought and likewise is. This very content, the unity of Being and thought, is thus indeed the true content; but because Anselm has it before him only in the form of the understanding, the opposites are identical and conformable to unity in a third determination only—the Highest—which, in as far as it is regulative, is outside of them. In this it is involved that we should first of all have subjective thought, and then distinguished from that, Being. We allow that if we think a content (and it is apparently indifferent whether this is God or any other), it may be the case that this content does not exist. The assertion “Something that is thought does not exist” is now subsumed under the above standard and is not conformable to it. We grant that the truth is that which is not merely thought but which likewise is. But of this opposition nothing here is said. Undoubtedly God would be imperfect, if He were merely thought and did not also have the determination of Being. But in relation to God we must not take thought as merely subjective; thought here signifies the absolute, pure thought, and thus we must ascribe to Him the quality of Being. On the other hand if God were merely Being, if He were not conscious of Himself as self-consciousness, He would not be Spirit, a thought that thinks itself.
Kant, on the other hand, attacked and rejected Anselm’s proof—which rejection the whole world afterwards followed up—on the ground of its being an assumption that the unity of Being and thought is the highest perfection. What Kant thus demonstrates in the present day—that Being is different from thought and that Being is not by any means posited with thought—was a criticism offered even in that time by a monk named Gaunilo. He combated this proof of Anselm’s in a Liber pro insipiente to which Anselm himself directed a reply in his Liber apologeticus adversus insipientem.[22] Thus Kant says (Kritik der reinen Vernunft, p. 464 of the sixth edition): If we think a hundred dollars, this conception does not involve existence. That is certainly true: what is only a conception does not exist, but it is likewise not a true content, for what does not exist, is merely an untrue conception. Of such we do not however here speak, but of pure thought; it is nothing new to say they are different—Anselm knew this just as well as we do. God is the infinite, just as body and soul, Being and thought are eternally united; this is the speculative, true definition of God. To the proof which Kant criticizes in a manner which it is the fashion to follow now-a-days, there is thus lacking only the perception of the unity of thought and of existence in the infinite; and this alone must form the commencement.
Other proofs such, for example, as the cosmological, which argues from the contingency of the world to an absolute existence, have thereby not reached the idea of absolute essence as spirit, and are without consciousness of the fact that it is an object of thought. The old physico-theological proof, which even Socrates possessed, from beauty, order, organic ends, indeed implies an understanding, a richer thought of absolute existence, and not alone an indeterminate Being, but in this proof it likewise remains unknown that God is the Idea. And then what sort of an understanding is God? A different and immediate one; then this spirit is independent. Further, disorder likewise exists, and thus there must be something else conceived of than this apparent order of nature only. But from asking about the existence of God, from making his objective mode a predicate and thus knowing that God is Idea, to pass to making the absolute existence I = I, thinking self-consciousness, not as predicate but in such a way that each thinking I is the moment of this self-consciousness—is still a long stride. Here, where we see this form first emerge, absolute existence is clearly to be taken as the Beyond of finite consciousness; this is to itself the null and void, and it has not yet grasped its sense of self. Its thoughts regarding things are manifold, and the mere fact of being a thing is to it likewise just such a predicate as the rest; but it is thereby not yet turned back within itself, it knows of existence, but not of itself.
In this, says Tennemann (Vol. VIII. Sec. I. p. 121), “Anselm has laid the first formal ground of scholastic theology;” but even before this the same was present, only to a more limited extent, and merely for individual dogmas—as is also the case with Anselm. His writings bear witness of great penetration and mental ability; and he gave rise to the philosophy of the scholastics, inasmuch as he united theology to philosophy. The theology of the Middle Ages thus stands much higher than that of modern times; never have Catholics been such barbarians as to say that there should not be knowledge of the eternal truth, and that it should not be philosophically comprehended. This is one point which has to be specially noted in Anselm, the other is that he apprehended in its unity that highest opposition between thought and Being spoken of above.
[b. Abelard.]
With Anselm Peter Abelard is associated, both being mainly concerned in the introduction of philosophy into theology. Abelard lived about 1100—from 1079 to 1142—and is famed for his learning, but still more famed in the world of sentiment and passion for his love to Heloise and his after fate.[23] After the days of Anselm he attained to great repute, and he followed him in his treatment of the doctrines of the Church, more especially seeking to give a philosophic proof of the Trinity. He taught at Paris. Paris about this time was to the theologians what Bologna was to the jurists, the central point of the sciences; it was at that time the seat of philosophizing theology. Abelard often delivered his lectures there before a thousand listeners. Theological science and philosophizing regarding it, was in France (as was jurisprudence in Italy) a matter of great importance, which, as most significant in the development of France, has hitherto been too much neglected. The conception prevailed that philosophy and religion were one and the same; which they absolutely speaking are. But the distinction was soon reached, “that much may be true in philosophy and false in theology:” this the Church denied. Tennemann (Vol. VIII. Sec. II. pp. 460, 461) quotes as follows from a rescript of the Bishop Stephen: “They say that this is true according to philosophy, and not according to the Catholic faith, just as if there were two contradictory truths, and as if in the doctrines of the accursed heathen a truth contradictory to the truth of the holy scriptures could be present.” While then undoubtedly, through the separation of the four faculties in the University of Paris which came about in 1270, philosophy became separated from theology, it was yet forbidden to it to subject theological beliefs and dogmas to disputation.[24]
[2. Methodical Representation of the Doctrinal System of the Church.]
We now go on to the more definite form which the scholastic theology reached; for in a second development of scholastic philosophy the main endeavour became to make the teaching of the Christian Church methodical, while still keeping its connection with all previous metaphysical arguments. These and their counter-arguments were placed side by side in stating every dogma, so that theology became represented in a scientific system, while before this the ecclesiastical teaching in the general education of the clergy was limited to the propounding of successive dogmas, and the writing down of passages from Augustine and other Fathers bearing on each proposition.
[a. Peter Lombard.]
Peter of Novara in Lombardy was the first of those who brought this to pass; he dates from the middle of the twelfth century, and was the originator of this method. He died in the year 1164. Petrus Lombardus set forth a whole system of scholastic theology which remained for several centuries the basis of the doctrine of the Church. He composed to that end his Quatuor libros sententiarum, and hence he likewise received the name Magister sententiarum. For in those times every learned schoolman had some predicate such as Doctor acutus, invincibilis, sententiosus, angelicus, &c. Others also availed themselves of the same title for their works; thus Robert Pulleyn wrote Sententiarum libros octo.[25]
