All the Philosophy which we first encounter in the Middle Ages, when independent states begin to rise, consists of bare remnants of the Roman world, which on its Fall had sunk in all respects so low that the culture of the world seemed to have come entirely to an end. Thus in the West hardly anything was known beyond the Isagoge of Porphyry, the Latin Commentaries of Boethius on the Logical works of Aristotle, and extracts from the same by Cassiodorus—most barren compilations; there is also what is just as barren, the dissertations ascribed to Augustine De dialectica and De categoriis, which last is a paraphrase of the Aristotelian work upon the categories.[15] These were the first make-shifts or expedients for carrying on Philosophy; in them the most external and most formal reasoning is applied.
The whole effect of the scholastic philosophy is a monotonous one. In vain have men hitherto endeavoured to show in this theology, which reigned from the eighth or even sixth century almost to the sixteenth, particular distinctions and stages in development. In this case as in that of the Arabian philosophy, time does not allow—and if it did the nature of things would not allow—us to separate the scholastic philosophy into its individual systems or manifestations, but only to give a general sketch of the main elements present therein which it has actually taken up into thought. It is not interesting by reason of its matter, for we cannot remain at the consideration of this; it is not a philosophy. The name, however, properly speaking indicates a general manner rather than a system—if we may speak of a philosophic system. Scholasticism is not a fixed doctrine like Platonism or Scepticism, but a very indefinite name which comprehends the philosophic endeavours of Christendom for the greater part of a thousand years. However, this history which occupies nearly a thousand years is, as a matter of fact, comprised within one Notion which we propose to consider more closely; it has ever occupied the same standpoint, and been grounded on the same principle; for it is the faith of the Church that we catch sight of, and a formalism which is merely an eternal analysis and constant re-iteration within itself. The more general acceptance of the Aristotelian writings has merely brought forth a difference of degree and caused no real scientific progress. Here there is indeed a history of men, but speaking properly none of scientific knowledge; the men are noble, pious, and in all respects most distinguished.
The study of the scholastic philosophy is a difficult one, even if its language only be considered. The Scholastics certainly make use of a barbaric Latin, but this is not the fault of the Scholastics but of their Latin culture. Latin forms a quite unsuitable instrument for applying to philosophic categories such as these, because the terms which the new culture adopts could not possibly be expressed by this language without unduly straining it; the beautiful Latin of Cicero is not adapted for use in profound speculations. It cannot be expected of anyone to know at first hand this philosophy of the Middle Ages, for it is as comprehensive and voluminous as it is barren and ill-expressed.
Of the great schoolmen we still have many works left to us which are very lengthy, so that it is no easy task to study them: the later they are, the more formal do they become. The Schoolmen did not only write compendiums—for the writings of Duns Scotus amount to twelve, and those of Thomas Aquinas to eighteen folios. Abstracts of them are to be found in various works. The principal sources from which we obtain our knowledge are: 1, Lambertus Danæus in the Prolegomena to his Commentarius in librum primum sententiarum Petri Lombardi, Genevæ, 1580. (This is the best authority we have in abridged form); 2, Launoi: De varia Aristotelis in Academia Parisiensi fortuna; 3, Cramer: Continuation of Bossuet’s History of the World, in the last two volumes; 4, the Summa of Thomas Aquinas. In Tiedemann’s History of Philosophy extracts from the Scholastics are also to be found, as likewise in Tennemann; Rixner also makes judicious extracts.
We shall limit ourselves to general points of view. The name finds its origin in this way. From the time of Charles the Great it was only in two places—in the great schools attached to the great cathedral churches and monasteries—that a cleric, that is a canon who had the oversight of the instructors (informatores), was called scholasticus; he likewise gave lectures on the most important branch of science, theology. In the monasteries he who was the most advanced instructed the monks. We have not, properly speaking, to deal with these; but although scholastic philosophy was something altogether different, the name of Scholastics attached itself to those alone who propounded their theology scientifically and in a system. In place of the patres ecclesiæ there thus arose later on the doctores.
The scholastic philosophy is thus really theology, and this theology is nothing but philosophy. The further content of theology is merely that which is present in the ordinary conceptions of religion; theology, however, is the science of the system as it must necessarily be present within every Christian, every peasant, &c. The science of theology is often placed in an external historical content, in exegesis, in the enumeration of the various manuscripts of the New Testament, in considering whether these are written on parchment, cotton fabrics or paper, whether in uncial letters or otherwise, and which century they belong to; further matters for consideration are the Jewish conceptions of time, the history of the Popes, Bishops and Fathers, and what took place at the councils of the Church. All these matters, however, do not pertain to the nature of God and its relation to mankind. The one essential object of theology as the doctrine of God, is the nature of God, and this content is in its nature really speculative; those theologians who consider this are therefore nothing less than philosophers. The science of God is nothing but Philosophy. Philosophy and theology have hence here also been counted one, and it is their separation that constitutes the transition into modern times, seeing that men have thought that for thinking reason something could be true which is not true for theology. Down to the Middle Ages, on the contrary, it was held as fundamental that there should be but one truth. Thus the theology of the scholastics is not to be represented as though, as with us, it merely contained doctrines about God, &c., in historic guise, for in fact it also has within it the profoundest speculations of Aristotle and of the Neo-Platonists. Their philosophy, and much in them that is excellent, is found in Aristotle, only in a simpler and purer form; and to them too the whole lay beyond actuality and mingled with Christian actuality as it is represented to us.
From Christianity, within whose bounds we now have our place, Philosophy has to re-establish its position. In heathendom the root of knowledge was external nature as thought devoid of self, and subjective nature as the inward self. Both Nature and the natural self of mankind, and likewise thought, there possessed affirmative significance; hence all this was good. In Christianity the root of truth has, however, quite another meaning; it was not only the truth as against the heathen gods, but as against Philosophy also, against nature, against the immediate consciousness of man. Nature is there no longer good, but merely a negative; self-consciousness, the thought of man, his pure self, all this receives a negative position in Christianity. Nature has no validity, and affords no interest; its universal laws, as the reality under which the individual existences of nature are collected, have likewise no authority: the heavens, the sun, the whole of nature is a corpse. Nature is given over to the spiritual, and indeed to spiritual subjectivity; thus the course of nature is everywhere broken in upon by miracles. With this surrender of natural necessity we have the fact associated that all further content, all that truth which constitutes the universal of that nature, is given and revealed. The one starting-point, the contemplation of nature, is thus for knowledge undoubtedly not present. Then this fact is likewise set aside that I am present as a self. The self as this immediate certainty has to be abrogated; it must also merge itself in another self, but in one beyond, and only there does it have its value. This other self, in which the proper self is made to have its freedom, is first of all likewise a particular self, that has not the form of universality: it is determined and limited in time and space, and at the same time has the significance of an absolute in and for itself. A real sense of self is thus abandoned, but what self-consciousness on the other hand gains is not a universal, a thought. In thought I have real affirmative significance, not as an individual, but as universal ‘I’; the content of truth is now, however, plainly individualized, and thus the thought of the ‘I’ falls away. Thereby, however, the highest concrete content of the absolute Idea is set forth, in which the opposites that are plainly infinite are united; it is the power which unites in itself what appears to consciousness infinitely removed from one another—the mortal and the absolute. This absolute is itself ‘this’ first of all as this concrete, not as abstraction, but as the unity of universal and individual; this concrete consciousness is for the first time truth. The reason of the former content being also true, comes to me as something not pertaining to myself, but as a thing received outside of self. The testimony of spirit, indeed, pertains thereto, and my inmost self is present there; but the testimony of spirit is a thing concealed, which does not further reveal itself, does not beget the content from itself, but receives it. The Spirit which bears witness is further itself distinguished from me as an individual; my testifying spirit is another, and there only remains to me the empty shell of passivity. Conditioned by this inflexible standpoint, Philosophy had to go forth once more. The first working up of this content, the inward operation of universal thought in the same, is the task scholastic philosophy has to undertake. The opposition between faith and reason forms the end arrived at; reason, on the one hand, feels the necessity of setting to work on nature in order to obtain immediate certainty, and on the other hand of finding in genuine thought, in specific production out of self, this same satisfaction.
We must now speak of the methods and manners of the scholastics. In this scholastic activity thought pursues its work quite apart from all regard to experience; we no longer hear anything of taking up actuality and determining it through thought. Although the Notion came into recognition earlier than this, in Aristotle, in the first place, the Notion was not apprehended as the necessity of carrying the content further; for this was received in its successive manifestations, and there was present merely an intermingling of actuality accepted as truth and of thought. Still less, in the second place, was the greater part of the content permeated by Notions, for this content was taken up superficially into the form of thought—more especially with the Stoics and Epicureans. The scholastic philosophy altogether dissociates itself from any such endeavours; it leaves actuality to exist alongside itself as if it were despised and had no interest. For reason found its true existence, its actualization, in another world and not in this; the whole progress of the cultivated world goes, however, to the re-instalment of a faith in the present world. Nevertheless, at first all knowledge and action, and whatever relates to an interest in this world, were entirely banished. Branches of knowledge that pertain to such ordinary matters as sight and hearing, restful contemplation and occupation with ordinary actuality here found no place; nor did such sciences as recognize a definite sphere of actuality after their own particular fashion, and constitute the material for genuine philosophy, nor arts which give to the Idea a sensuous existence. Likewise law and right, the recognition of the actual man, were not esteemed as pertaining to the social relationships of life, but to some other sphere. In this absence of rationality in the actual, or of rationality which has its actuality in ordinary existence, is found the utter barbarism of thought, in that it keeps to another world, and does not have the Notion of reason—the Notion that the certainty of self is all truth.
Now thought as sundered has a content, the intelligible world, as an actuality existent for itself, to which thought applies itself. Its conduct is here to be compared with that which takes place when the understanding applies itself to the sensuous and perceptible world, makes it as substance its basis, having a fixed object in it, and reasoning respecting it; it is then not the independent movement of Philosophy proper which penetrates existence and expresses it, for all it does is to find predicates regarding it. The scholastic philosophy has thus the intelligible world of the Christian religion, God and all His attributes and works therewith connected, as an independent object; and thought is directed to God’s unchangeableness, to such questions as whether matter is eternal, whether man is free, &c.—just as the understanding passes to and fro over the phenomenal and perceived. Now the scholastic philosophy was here given over to the infinite movement of determinate Notions; the categories of possibility and actuality, freedom and necessity, constitution and substance, &c., are of this nature, they are not fixed, but pure movements. Anything whatever, determined as potential, transforms itself equally into the opposite, and must necessarily be surrendered; and determination can only save itself by a new distinction, because it must, on the one hand, be given up, and on the other retained. The scholastics are thus decried on account of the endless distinctions which they draw. For the sake of these determinations through the abstract Notion the Aristotelian philosophy was predominant, though not in its whole extent. It was the Aristotelian Organon that was held in such favour, and that indeed just as much for its laws of thought as for its metaphysical conceptions—the categories. These abstract Notions constituted in their determinateness the understanding of the scholastic philosophy, which could not pass beyond itself and attain to freedom, nor seize upon the freedom given by reason.
With this finite form a finite content is likewise directly associated. From one determination we pass on to another, and such determinations, as particular, are finite; the determination there relates itself externally and not as self-comprehensive and self-embracing. The result of this determination is that thought will really act as if it brought about conclusions, for to draw conclusions is the mode of formal logical progression. Philosophy thus consists of a methodical and syllogistic reasoning. Just as the Sophists of Greece wandered about amongst abstract conceptions on behalf of actuality, so did the scholastics on behalf of their intellectual world. To the former Being had validity; it they had rescued and delivered as against the negativity of the Notion, while along with that they had justified it through the same. The principal endeavour of the scholastics was in the same way to vindicate the Christian intellectual world as against the confusion of the Notion, and through the latter to demonstrate its conformity with the same. The universal form of the scholastic philosophy thus consisted in this—that a proposition was laid down, the objections to it brought forward, and these contradicted through counter-propositions and distinctions. Philosophy was hence not separated from theology, as it is not in itself, for Philosophy is the knowledge of absolute existence, that is to say, theology. But to that theology the Christian absolute world was a system which was held to be an actuality, as was ordinary actuality for the Greek sophists. Of Philosophy proper there thus remained only the laws of thought and abstractions.
