Aristotle

that Alexander furnished to his master 250,000l. and the services of several thousand men, for the purpose of obtaining and examining the specimens required in the composition of his work on the "History of Animals" may be an exaggeration, but there can be no doubt that in these transactions was the real beginning of that policy which soon led to the institution of the Museum at Alexandria. The importance of this event, Origin of the though hitherto little understood, admits of no influence of exaggeration, so far as the intellectual progress through of Europe is concerned. It gave to the works Alexander. of Aristotle their wonderful duration; it imparted to them not only a Grecian celebrity, but led to their translation into Syriac by the Nestorians in the fifth century, and from Syriac by the Arabs into their tongue four hundred years later. They exercised a living influence over Christians and Mohammedans indifferently, from Spain to Mesopotamia.

If the letter quoted by Plutarch as having been written by Alexander to Aristotle be authentic, it not only shows how thoroughly the pupil had been indoctrinated into the wisdom of the master, but warns us how liable we are to be led astray in the exposition we are presently to give of the Aristotelian philosophy. There was then, as unfortunately there has been too often since, a private as well as a public doctrine. Alexander upbraids the philosopher for his indiscretion in revealing things that it was understood should be concealed. Aristotle defends himself by asserting that the desired concealment had not been broken. By many other incidents of a trifling kind the attachment of the conqueror to philosophy is indicated; thus Harpalus and Nearchus, the companions of his youth, were Scientific the agents employed in some of his scientific training and undertakings, the latter being engaged in sea undertakings explorations, doubtless having in the main a political object, yet full of interest to science. Alexander lived, Nearchus was to have repeated the circumnavigation of Africa. Harpalus, while governor of Babylon, was occupied in the attempt to exchange the vegetation of Europe and Asia; he intertransplanted the productions of Persia and Greece, succeeding, as is related,

in his object of making all European plants that he tried, except the ivy, grow in Mesopotamia. The journey to the Caspian Sea, the expedition into the African deserts, indicate Alexander's personal taste for natural knowledge; nor is it without significance that, while on his death-bed, and, indeed, within a few days of his decease, he found consolation and amusement in having Nearchus by his side relating the story of his voyages. Nothing shows more strikingly how correct was his military perception than the intention he avowed of equipping a thousand ships for the conquest of Carthage, and thus securing his supremacy in the Mediterranean. Notwithstanding all this, there were many points of his character, and many events of his life, worthy of the condemnation with which His unbridled they have been visited; the drunken burning passions and of Persepolis, the prisoners he slaughtered in iniquities. honour of Hephaestion, the hanging of Callisthenes, were the results of intemperance and unbridled passion. Even so steady a mind as his was incapable of withstanding the influence of such enormous treasures as those he seized at Susa; the plunder of the Persian empire; the inconceivable luxury of Asiatic life; the uncontrolled power to which he attained. But he was not so imbecile as to believe himself the descendant of Jupiter Ammon; that was only an artifice he permitted for the sake of influencing those around him. We must not forget that he lived in an age when men looked for immaculate conceptions and celestial descents. These Asiatic ideas had made their way into Europe. The Athenians themselves were soon to be reconciled to the appointment of divine honours to such as Antigonus and Demetrius, adoring them as gods-saviour gods—and instituting sacrifices and priests for their worship.

Greece had gone through her age of Credulity, her age of Inquiry, her age of Faith; she had entered on her age of Reason, and, had freedom of action been permitted to her, she would have given a decisive tone to the forthcoming civilization of Europe.

In her old Its inability age, the power of Europe, concentrated in the to accomplish Roman empire, overthrew her. There are very tion of few histories of the past of more interest to Europe. modern times, and none, unfortunately, more misunderstood, than this Greek age of Reason manifested at Alexandria. It illustrates, in the most signal manner, that affairs control men more than men control affairs. The scientific associations of the Macedonian conqueror directly arose from the contemporaneous state of Greek philosophy in the act of reaching the close of its age of faith, and these influences ripened under the Macedonian captain who became King of Egypt. As it was, the learning of Alexandria, though diverted from its most appropriate and desirable direction by the operation of the Byzantine system, in the course of a few centuries acting forcibly upon it, was not without an influence on the future thought of Europe. Even at this day Europe will not bear to be fully told how great that influence has been.

The age of Reason, to which Aristotle is about to introduce us, stands in striking contrast to the preceding ages. It cannot escape the reader that what was done by the men of science in Alexandria resembles what is doing in our own times; their day was the foreshadowing of ours. And yet a long and dreary period of almost twenty centuries parts us from them. Politically, Aristotle, through his friendship with Alexander and the perpetua- The writings tion of the Macedonian influence in Ptolemy, of Aristotle was the connecting link between the Greek age are its prelude. of Faith and that of Reason, as he was also philosophically by the nature of his doctrines. He offers us an easy passage from the speculative methods of Plato to the scientific methods of Archimedes and Euclid. The copiousness of his doctrines, and the obscurity of many of them, might, perhaps, discourage a superficial student, unless he steadily bears in mind the singular authority they maintained for so many ages, and the brilliant results in all the exact parts of human knowledge to which they so quickly led. The history of Aristotle and his philosophy is therefore

our necessary introduction to the grand, the immortal achievements of the Alexandrian school.

Aristotle.

Aristotle was born at Stagira, in Thrace, B.C. 384. His Biography of father was an eminent author of those times on subjects of Natural History; by profession he was a physician. Dying while his son was yet quite young, he bequeathed to him not only very ample means, but also his own tastes. Aristotle soon found his way to Athens, and entered the school of Plato, with whom it is said he remained for nearly twenty years. During this period he spent most of his patrimony, and in the end was obliged to support himself by the trade of a druggist. At length differences arose between them, for, as we shall soon find, the great pupil was by no means a blind follower of the great master. In a fortunate moment, Philip, the King of Macedon, appointed him preceptor to his son Alexander, an incident of importance in the intellectual history of Europe. It was to the friendship arising through this relation that Aristotle owed the assistance he received from the conqueror during his Asiatic expedition for the composition of "the Natural History," and also gained that prestige which gave his name such singular authority for more than fifteen centuries. He eventually founded a school in the Lyceum at Athens, and, as it was his habit to deliver his lectures while walking, his disciples received the name of Peripatetics, or walking philosophers. These lectures were of two kinds, esoteric and exoteric, the former being delivered to the more advanced pupils only. He wrote a very large number of works, of which about one-fourth remain.

Aristotle, on the contrary, rose from particulars to universals, advancing to them by inductions; and his system, thus an inductive philosophy, was in reality the true beginning of science.

Plato therefore trusts to the Imagination, Aristotle to Reason. The contrast between them is best seen by the attitude in which they stand as respects the Ideal theory.

that of Plato.

Plato regards universals, types, or exemplars as having an actual existence; Aristotle declares that they His method are mere abstractions of reasoning. For the compared with fanciful reminiscences derived from former experience in another life by Plato, Aristotle substitutes the reminiscences of our actual experience in this. These ideas of experience are furnished by the memory, which enables us not only to recall individual facts and events witnessed by ourselves, but also to collate them with one another, thereby discovering their resemblances and their differences. Our induction becomes the more certain as our facts are more numerous, our experience larger. "Art commences when, from a great number of experiences, one general conception is formed which will embrace all similar cases.' "If we properly observe celestial phenomena, we may demonstrate the laws which regulate them." With Plato, philosophy arises from faith in the past; with Aristotle, reason alone can constitute it from existing facts. Plato is analytic, Aristotle synthetic. The philosophy of Plato arises from the decomposition of a primitive idea into particulars, that of Aristotle from the union of particulars into a general conception. The former is essentially an idealist, the latter a materialist.

Aristotelism.

From this it will be seen that the method of Plato was capable of producing more splendid, though The results of they were necessarily more unsubstantial results; Platonism and that of Aristotle was more tardy in its operation, but much more solid. It implied endless labour in the collection of facts, the tedious resort to experiment and observation, the application of demonstration. In its very nature it was such that it was impossible for its author to carry by its aid the structure of science to completion. The moment that Aristotle applies his own principles we find him compelled to depart from them through want of a sufficient experience and sufficient precision in his facts. The philosophy of Plato is a gorgeous castle in the air, that of Aristotle is a solid structure, laboriously, and, with many failures, founded on the solid rock.

Under Logic, Aristotle treats of the methods of arriving at general propositions, and of reasoning from them. His logic is at once the art of thinking and the instrument
