The want of subjectivity is really the want of the Greek moral idea. The principle which became prominent with Socrates had been present up to this time only in a more subordinate capacity; now it of necessity became an even absolute principle, a necessary moment in the Idea itself. By the exclusion of private property and of family life, by the suspension of freedom in the choice of the class, i.e. by the exclusion of all the determinations which relate to the principle of subjective freedom, Plato believes he has barred the doors to all the passions; he knew very well that the ruin of Greek life proceeded from this, that individuals, as such, began to assert their aims, inclinations, and interests, and made them dominate over the common mind. But since this principle is necessary through the Christian religion—in which the soul of the individual is an absolute end, and thus has entered into the world as necessary in the Notion of the mind—it is seen that the Platonic state-constitution cannot fulfil what the higher demands of a moral organism require. Plato has not recognized the knowledge, wishes, and resolutions of the individual, nor his self-reliance, and has not succeeded in combining them with his Idea; but justice demands its rights for this just as much as it requires the higher resolution of the same, and its harmony with the universal. The opposite to Plato’s principle is the principle of the conscious free will of individuals, which in later times was by Rousseau more especially raised to prominence: the theory that the arbitrary choice of the individual, the outward expression of the individual, is necessary. In this the principle is carried to the very opposite extreme, and has emerged in its utter one-sidedness. In opposition to this arbitrariness and culture there must be the implicitly and explicitly universal, that which is in thought, not as wise governor or morality, but as law, and at the same time as my Being and my thought, i.e. as subjectivity and individuality. Men must have brought forth from themselves the rational along with their interests and their passions, just as it must enter into reality through the necessities, opportunities, and motives that impel them.
There is still another celebrated side of the Platonic philosophy which may be considered, namely æsthetics, the knowledge of the beautiful. In respect to this, Plato has in like manner seized the one true thought, that the essence of the beautiful is intellectual, the Idea of reason. When he speaks of a spiritual beauty, he is to be understood in the sense that beauty, as beauty, is sensuous beauty, which is not in some other place—no one knows where; but what is beautiful to the senses is really the spiritual. The case is the same here as it is with his Idea. As the essence and truth of phenomena in general is the Idea, the truth of phenomenal beauty must also be this Idea. The relation to the corporeal, as a relation of the desires, or of pleasure and utility, is no relation to it as the beautiful; it is a relation to it as the sensuous alone, or a relation of particular to particular. But the essence of the beautiful is just the simple Idea of reason present to the sensuous apprehension as a thing; the content of the thing is nothing else than this.[77] The beautiful is essentially of spiritual nature; it is thus not merely a sensuous thing, but reality subject to the form of universality, to the truth. This universal does not, however, retain the form of universality, but the universal is the content whose form is the sensuous mode; and therein lies the determination of the beautiful. In science, the universal has again the form of the universal or of the Notion; but the beautiful appears as an actual thing—or, when put into words, as a popular conception, in which mode the material exists in mind. The nature, essence, and content of the beautiful is recognized and judged by reason alone, as its content is the same as that of Philosophy. But because reason appears in the beautiful in material guise, the beautiful ranks below knowledge, and Plato has for this very reason placed the true manifestation of reason in knowledge, where it is spiritually manifested.
This may be regarded as the kernel of Plato’s philosophy. His standpoint is: first, the contingent form of speech, in which men of noble and unfettered nature converse without other interest than that of the theory which is being worked out; secondly, led on by the content, they reach the deepest Notions and the finest thoughts, like jewels on which one stumbles, if not exactly in a sandy desert, yet at least upon the arid path; in the third place, no systematic connection is to be found, though one interest is the source of all; in the fourth place, the subjectivity of the Notion is lacking throughout; but in the fifth place, the substantial Idea forms the principle.
Plato’s philosophy had two stages through which it of necessity developed and worked its way up to a higher principle. The universal which is in reason had first to fall into two divisions opposed to each other in the most direct and unmitigated contradiction, in the independence of the personal consciousness which exists for itself: thus in the New Academy self-consciousness goes back into itself, and becomes a species of scepticism—the negative reason, which turns against all that is universal, and fails to find the unity of self-consciousness and the universal, coming accordingly to a standstill at that point. But, in the second place, the Neo-Platonists constitute the return, this unity of self-consciousness and the absolute essence; to them God is directly present in reason, reasoned knowledge itself is the Divine Spirit, and the content of this knowledge is the Being of God. Both of these we shall consider later.
[B. Aristotle.]
Here we leave Plato, and we do so with regret. But seeing that we pass to his disciple, Aristotle, we fear that it behoves us to enter even more into detail, since he was one of the richest and deepest of all the scientific geniuses that have as yet appeared—a man whose like no later age has ever yet produced. Because we still possess so large a number of his works, the extent of the material at hand is proportionately greater; unfortunately, however, I cannot give to Aristotle the amount of attention that he deserves. For we shall have to confine ourselves to a general view of his philosophy, and simply remark on one particular phase of it, viz. in how far Aristotle in his philosophy carried out what in the Platonic principle had been begun, both in reference to the profundity of the ideas there contained, and to their expansion; no one is more comprehensive and speculative than he, although his methods are not systematic.
As regards the general character of Aristotle’s writings, he may be said to have extended his attention to the whole circle of human conceptions, to have penetrated all regions of the actual universal, and to have brought under the subjection of the Notion both their riches and their diversitude. For most of the philosophic sciences have to render thanks to him both for their characterization and first commencement. But although in this way Science throughout falls into a succession of intellectual determinations of determinate Notions, the Aristotelian philosophy still contains the profoundest speculative Notions. Aristotle proceeds in reference to the whole in the same way as in the individual case. But a general view of his philosophy does not give us the impression of its being in construction a self-systematized whole, of which the order and connection pertain likewise to the Notion; for the parts are empirically selected and placed together in such a way that each part is independently recognized as a determinate conception, without being taken into the connecting movement of the science. We need not try to demonstrate necessity from the standpoint of the philosophy of that time. But although Aristotle’s system does not appear to be developed in its parts from the Notion, and its parts are merely ranged side by side, they still form a totality of truly speculative philosophy.
One reason for treating of Aristotle in detail rests in the fact that no philosopher has had so much wrong done him by the thoughtless traditions which have been received respecting his philosophy, and which are still the order of the day, although for centuries he was the instructor of all philosophers. For to him views are ascribed diametrically opposite to his philosophy. And while Plato is much read, the treasures contained in Aristotle have for centuries, and until quite modern times, been as good as unknown, and the falsest prejudices reign respecting him. Almost no one knows his speculative and logical works; in modern times more justice has been done to his writings regarding nature, but not to his philosophic views. For instance, there is a quite generally held opinion that the Aristotelian and Platonic philosophies are directly opposed, the one being idealistic and the other realistic, and that, indeed, in the most trivial sense. For Plato is said to have made the ideal his principle, so that the inward idea creates from itself; according to Aristotle, on the contrary, we are told that the soul is made a tabula rasa, receiving all its determinations quite passively from the outer world; and his philosophy is thus mere empiricism—Locke’s philosophy at its worst. But we shall see how little this really is the case. In fact Aristotle excels Plato in speculative depth, for he was acquainted with the deepest kind of speculation—idealism—and in this upholds the most extreme empirical development. Quite false views respecting Aristotle even now exist in France. An example of how tradition blindly echoes opinions respecting him, without having observed from his works whether they are justified or not, is the fact that in the old Æsthetics the three unities of the drama—action, time and place—were held to be règles d’Aristote, la saine doctrine. But Aristotle speaks (Poet. c. 8 et 5)[78] only of the unity of treatment, or very occasionally of the unity of time; of the third unity, that of place, he says nothing.
As regards Aristotle’s life, he was born at Stagira, a Thracian town on the Strymonian Gulf, but a Greek colony. Thus, though a Thracian, he was by birth a Greek. This Greek colony fell, however, like The rest of the country, under the rule of Philip of Macedon. The year of Aristotle’s birth is the first of the 99th Olympiad (384 B.C.), and if Plato was born in the third year of the 87th Olympiad (430 B.C.), Aristotle must have been forty-six years younger than he. His father Nicomachus was physician to the Macedonian king, Amyntas, the father of Philip. After the death of his parents, whom he lost early, he was brought up by a certain Proxenus, to whom he was ever grateful; and during all his life he held the memory of this friend in such high esteem, that he honoured it by erecting statues to him. He also requited Proxenus for the education given him, by later on bringing up his son Nicanor, adopting him as his own son and making him his heir. In the seventeenth year of his age Aristotle came to Athens, and remained there twenty years in company with Plato.[79] He thus had the best possible opportunity of becoming thoroughly acquainted with Plato’s philosophy, and therefore, if we are told that he did not understand it (Vol. I p. 167), this is shown, by the evident facts of the case, to be an arbitrary and quite unfounded assumption. As regards the relation of Plato to Aristotle, and particularly as regards the fact that Plato did not select Aristotle as his successor in the Academy, but chose Speusippus, a near relative, instead, a number of idle and contradictory anecdotes have come to us from Diogenes (V. 2). If the continuation of the Platonic school was designed to express the hope that the philosophy of Plato, as comprehended by himself, was to be there satisfactorily maintained, Plato could certainly not designate Aristotle as his successor, and Speusippus was the right man to be selected. However, Plato had nevertheless Aristotle as his successor, for Aristotle understood Philosophy in Plato’s sense, though his philosophy was deeper and more worked out, and thus he carried it further. Displeasure at being thus passed over is said to have been the cause of Aristotle’s leaving Athens after Plato’s death, and living for three years with Hermias, the Tyrant of Atarneus in Mysia, who had been a disciple of Plato along with Aristotle, and who had then struck up a close friendship with the latter. Hermias, an independent prince, was, together with other absolute Greek princes and some Republics, brought under the subjection of a Persian satrap in Asia Minor. Hermias was even sent as prisoner to Artaxerxes in Persia, and he at once caused him to be crucified. In order to avoid a similar fate, Aristotle fled with his wife Pythias, the daughter of Hermias, to Mitylene, and lived there for some time. He, however, erected a statue to Hermias in Delphi, with an inscription which has been preserved. From it we know that it was by cunning and treachery that he came under the power of the Persians. Aristotle also honoured his name in a beautiful hymn on Virtue, which has likewise come down to us.[80]
From Mitylene he was (Ol. 109, 2; 343 B.C.) summoned by Philip of Macedon to undertake the education of Alexander, who was then fifteen years old. Philip had already invited him to do this in the well-known letter that he addressed to him just after Alexander’s birth: “Know that a son is born to me, but I thank the gods less that they have given him to me, than that they have caused him to be born in your time. For I hope that your care and your wisdom will make him worthy of me and of his future kingdom.”[81] It certainly would appear to be a brilliant historic destiny to be the instructor of an Alexander, and Aristotle at this court enjoyed the favour and esteem of Philip and of Olympias in the highest degree. What became of Aristotle’s pupil is known to all, and the greatness of Alexander’s mind and deeds, as also his enduring friendship, are the best witnesses of the success, as also of the spirit of this up-bringing, if Aristotle required such testimony. Alexander’s education utterly refuted the common talk about the practical uselessness of speculative philosophy. Aristotle had in Alexander another and worthier pupil than Plato found in Dionysius. Plato’s great interest was his Republic, the ideal of a state; he enters into relation with a person through whom it might be carried out; the individual was thus to him a medium only, and in so far indifferent to him. With Aristotle, on the other hand, this purpose was not present, he merely had the simple individual before him; and his end was to bring up and to develop the individuality as such. Aristotle is known to be a profound, thorough, and abstract metaphysician, and it is evident that he meant seriously with Alexander. That Aristotle did not follow with Alexander the ordinary superficial method of educating princes, might be confidently expected from the earnestness of one who well knew what was truth and true culture. It is also evident from the circumstance that Alexander, while in the midst of his conquests in the heart of Asia, when he heard that Aristotle had made known his acroamatic doctrines in speculative (metaphysical) writings, wrote him a reproachful letter, in which he said that he should not have made known to the common people what the two had worked out together. To this Aristotle replied that, though published, they were really just as much unpublished as before.[82]
