A History of Philosophy in Epitome

by Albert Schwegler

This devotion of Aristotle to that which is given will also explain his predominant inclination towards physics, for nature is the most immediate and actual. Connected also with this is the fact that Aristotle is the first among philosophers who has given to history and its tendencies an accurate attention. The first book of the Metaphysics is also the first attempt at a history of philosophy, as his politics is the first critical history of the different states and constitutions. In both these cases he brings out his own theory only as the consequence of that which has been historically given, basing it in the former case upon the works of his predecessors, and in the latter case upon the constitutions which lie before him.

It is clear that according to this, the method of Aristotle must be a different one from that of Plato. Instead of proceeding like the latter, synthetically and dialectically, he pursues for the most part an analytic and regressive course, that is, going backward from the concrete to its ultimate ground and determination. While Plato would take his standpoint in the idea, in order to explain from this position and set in a clearer light that which is given and empirical, Aristotle on the other hand, starts with that which is given, in order to find and exhibit the idea in it. His method is, hence, induction; that is, the derivation of certain principles and maxims from a sum of given facts and phenomena; his mode of procedure is, usually, argument, a barren balancing of facts, phenomena, circumstances and possibilities. He stands out for the most part only as the thoughtful observer. Renouncing all claim to universality and necessity in his results, he is content to have brought out that which has an approximative truth, and the highest degree of probability. He often affirms that science does not simply relate to the changeless and necessary, but also to that which ordinarily takes place, that being alone excluded from its province, which is strictly accidental. Philosophy, consequently, has with him the character and worth of a reckoning of probabilities, and his mode of exhibition assumes not unfrequently only the form of a doubtful deliberation. Hence there is no trace of the Platonic ideals, hence, also, his repugnance to a glowing and poetic style in philosophy, a repugnance which, while indeed it induces in him a fixed, philosophical terminology, also frequently leads him to mistake and misrepresent the opinions of his predecessors. Hence, also, in whatever he treated, his thorough adherence to that which is actually given.

Connected in fine with the empirical character of the Aristotelian philosophizing, is the fragmentary form of his writings, and their want of a systematic division and arrangement. Proceeding always in the line of that which is given, from individual to individual, he considers every province of the actual by itself, and makes it the subject of a separate treatise; but he, for the most part, fails to indicate the lines by which the different parts hang together, and are comprehended in a systematic whole. Thus he holds up a number of co-ordinate sciences, each one of which has an independent basis, but he fails to give us the highest science which embraces them all. The principle is sometimes affirmed that all the writings follow the idea of a whole; but in their procedure there is such a want of all systematic connection, and every one of his writings is a monograph so thoroughly independent and complete in itself, that we are sometimes puzzled to know what Aristotle himself received as a part of philosophy, and what he excluded. We are never furnished with an independent scheme or outline, we rarely find definite results or summary explanations, and even the different divisions of philosophy which he gives, vary essentially from one another. At one time he divides science into theoretical and practical, at another, he adds to these two a poetical creative science, while still again he speaks of the three parts of science, ethics, physics, and logic. At one time he divides the theoretical philosophy into logic and physics, and at another into theology, mathematics, and physics. But no one of these divisions has he expressly given as the basis on which to represent his system; he himself places no value upon this method of division, and, indeed, openly declares himself opposed to it. It is, therefore, only for the sake of uniformity that we can give the preference here to the threefold division of philosophy as already adopted by Plato.

III. Logic and Metaphysics. 1. Conception and Relation of the Two.—The word metaphysics was first furnished by the Aristotelian commentators. Plato had used the term dialectics, and Aristotle had characterized the same thing as “first philosophy,” while he calls physics the “second philosophy.” The relation of this first philosophy to the other sciences Aristotle determines in the following way. Every science, he says, must have for investigation a determined province and separate form of being, but none of these sciences reaches the conception of being itself. Hence there is needed a science which should investigate that which the other sciences take up hypothetically, or through experience. This is done by the first philosophy which has to do with being as such, while the other sciences relate only to determined and concrete being. The metaphysics, which is this science of being and its primitive grounds, is the first philosophy, since it is presupposed by every other discipline. Thus, says Aristotle, if there were only a physical substance, then would physics be the first and the only philosophy, but if there be an immaterial and unmoved essence which is the ground of all being, then must there also be an antecedent, and because it is antecedent, a universal philosophy. The first ground of all being is God, whence Aristotle occasionally gives to the first philosophy the name of theology.

It is difficult to determine the relation between this first philosophy as the science of the ultimate ground of things, and that science which is ordinarily termed the logic of Aristotle, and which is exhibited in the writings bearing the name of the Organon. Aristotle himself has not accurately examined the relations of these two sciences, the reason of which is doubtless to be found in the incomplete form of the metaphysics. But since he has embraced them both under the same name of logic, since the investigation of the essence of things (VII. 17), and the doctrine of ideas (XIII. 5), are expressly called logical, since he repeatedly attempts in the Metaphysics (Book IV.), to establish the logical principle of contradiction as an absolute presupposition for all thinking and speaking and philosophizing, and employs the method of argument belonging to that science which has to do with the essence of things (III. 2. IV. 3), and since, in fine, the categories to which he had already dedicated a separate book in the Organon are also discussed again in the Metaphysics (Book V.), it follows that this much at least may be affirmed with certainty, that he would not absolutely separate the investigations of the Organon from those of the Metaphysics, and that he would not counsel the ordinary division of formal logic and metaphysics, although he has omitted to show more clearly their inner connection.

2. Logic.—The great problem both of the logical faculty and also of logic both as science and art, consists in this, viz., to form and judge of conclusions, and through conclusions to be able to establish a proof. The conclusions, however, arise from propositions, and the propositions from conceptions. According to this natural point of view, which lies in the very nature of the case, Aristotle has divided the content of the logical and dialectical doctrine contained in the different treatises of the Organon. The first treatise in the Organon is that containing the categories, a work which treats of the universal determinations of being, and gives the first attempt at an ontology. Of these categories Aristotle enumerates ten; essence, magnitude, quality, relation, the where, the when, position, habit, action, and passion. The second treatise (de interpretatione) investigates speech as the expression of thought, and discusses the doctrine of the parts of speech, propositions and judgments. The third are the analytic books, which show how conclusions may be referred back to their principles and arranged in order of their antecedence. The first Analytic contains in two books the universal doctrine of the Syllogism. Conclusions are according to their content and end either apodictic, which possess a certain and incontrovertible truth, or dialectic, which are directed toward that which may be disputed and is probable, or, finally, sophistic, which are announced deceptively as correct conclusions while they are not. The doctrine of apodictic conclusions and thus of proofs is given in the two books of the second Analytic, that of dialectic, is furnished in the eight books of the Topic, and that of sophistic in the treatise concerning “Sophistical Convictions.”

A closer statement of the Aristotelian logic would be familiar to every one, since the formal representations of this science ordinarily given, employ for the most part only the material furnished by Aristotle. Kant has remarked, that since the time of the Grecian sage, logic has made neither progress nor retrogression. Only in two points has the formal logic of our time advanced beyond that of Aristotle; first, in adding to the categorical conclusion which was the only one Aristotle had in mind, the hypothetical and disjunctive, and second, in adding the fourth to the first three figures of conclusion. But the incompleteness of the Aristotelian logic, which might be pardoned in the founder of this science, yet abides, and its thoroughly empirical method not only still continues, but has even been exalted to a principle by making the antithesis, which Aristotle did not, between the form of a thought and the content. Aristotle, in reality, only attempted to collect the logical facts in reference to the formation of propositions, and the method of conclusions; he has given in his logic only the natural history of finite thinking. However highly now we may rate the correctness of his abstraction, and the clearness with which he brings into consciousness the logical operation of the understanding, we must make equally conspicuous with this the want of all scientific derivation and foundation. The ten categories which he, as already remarked, has discussed in a separate treatise, he simply mentions, without furnishing any ground or principle for this enumeration; that there are this number of categories is only a matter of fact to him, and he even cites them differently in different writings. In the same way also he takes up the figures of the conclusion empirically; he considers them only as forms and determinations of relation of the formal thinking, and continues thus, although he allows the conclusion to stand for the only form of science within the province of the logic of the understanding. Neither in his Metaphysics nor in his Physics does he cite the rules of the formal methods of conclusion which he develops in the Organon, clearly proving that he has nowhere in his system properly elaborated either his categories or his analytic; his logical investigations do not influence generally the development of his philosophical thought, but have for the most part only the value of a preliminary scrutiny.

3. Metaphysics.—Among all the Aristotelian writings, the Metaphysics is least entitled to be called a connected whole; it is only a connection of sketches, which, though they follow a certain fundamental idea, utterly fail of an inner mediation and a perfect development. We may distinguish in it seven distinct groups. (1) Criticism of the previous philosophic systems viewed in the light of the four Aristotelian principles, Book I. (2) Positing of the apories or the philosophical preliminary questions, III. (3) The principle of contradiction, IV. (4) Definitions, V. (5) Examination of the conception of essence (οὐσία) and conceivable being (the τί ἦν εἴναι) or the conception of matter (ὕλη), form (εἶδος), and that which arises from the connection of these two (σύνολον), VII. VIII. (6) Potentiality and actuality, IX. (7) The Divine Spirit moving all, but itself unmoved, XII. (8) To these we may add the polemic against the Platonic doctrine of ideas and numbers, which runs through the whole Metaphysics, but is especially carried out in Books XIII. and XIV.

(1) The Aristotelian Criticism of the Platonic Doctrine of Ideas.—In Aristotle’s antagonism to the Platonic doctrine of ideas, we must seek for the specific difference between the two systems, a difference of which Aristotle avails himself of every opportunity (especially Metaph. I. and XIII.) to express. Plato had beheld every thing actual in the idea, but the idea was to him a rigid truth, which had not yet become interwoven with the life and the movement of existence. Such a view, however, had this difficulty, the idea, however little Plato would have it so, found standing over against it in independent being the phenomenal world, while it furnished no principle on which the being of the phenomenal world could be affirmed. This Aristotle recognizes and charges upon Plato, that his ideas were only “immortalized things of sense,” out of which the being and becoming of the sensible could not be explained. In order to avoid this consequence, he himself makes out an original reference of mind to phenomenon, affirming that the relation of the two is, that of the actual to the possible, or that of form to matter, and considering also mind as the absolute actuality of matter, and matter, as the potentially mind. His argument against the Platonic doctrine of ideas, Aristotle makes out in the following way.
