《【彩票网高手计划】欢迎访问》The final defeat of polytheism proved, in some respects, an advantage to Neo-Platonism, by compelling it to exchange theological controversy for studies which could be prosecuted, at least for a time, without giving umbrage to the dominant religion. At Alexandria the new spiritualism was associated, on genuinely Platonic principles, with the teaching of geometry by the noble and ill-fated Hypatia. In all the Neo-Platonic schools, whether at Rome, at Alexandria, at Constantinople, or at Athens, the writings of Plato and Aristotle were attentively studied, and made the subject of numerous commentaries, many of which are still extant. This return to the two great masters of idealism was, as we have already said, the most valuable result of the metaphysical revival, and probably contributed more than any other cause to the preservation of their works amidst the general wreck of ancient philosophical literature. Finally, efforts were made to present the doctrine of Plotinus under a more popular or a more scientific form, and to develope it into systematic completeness.
The idea of such a provisional code seems to have originated with Zeno;61 but the form under which we now know it is28 the result of at least two successive revisions. The first and most important is due to Panaetius, a Stoic philosopher of the second century B.C., on whose views the study of Plato and Aristotle exercised a considerable influence. A work of this teacher on the Duties of Man furnished Cicero with the materials for his celebrated De Officiis, under which form its lessons have passed into the educational literature of modern Europe. The Latin treatise is written in a somewhat frigid and uninteresting style, whether through the fault of Cicero or of his guide we cannot tell. The principles laid down are excellent, but there is no vital bond of union holding them together. We can hardly imagine that the author’s son, for whom the work was originally designed, or anyone else since his time, felt himself much benefited by its perusal. Taken, however, as a register of the height reached by ordinary educated sentiment under the influence of speculative ideas, and of the limits imposed by it in turn on their vagaries, after four centuries of continual interaction, the De Officiis presents us with very satisfactory results. The old quadripartite division of the virtues is reproduced; but each is treated in a large and liberal spirit, marking an immense advance on Aristotle’s definitions, wherever the two can be compared. Wisdom is identified with the investigation of truth; and there is a caution against believing on insufficient evidence, which advantageously contrasts with what were soon to be the lessons of theology on the same subject. The other great intellectual duty inculcated is to refrain from wasting our energies on difficult and useless enquiries.62 This injunction has been taken up and very impressively repeated by some philosophers in our own time; but in the mouth of Cicero it probably involved much greater restrictions on the study of science than they would be disposed to admit. And the limits now prescribed to speculation by Positivism will perhaps seem not less injudicious,29 when viewed in the light of future discoveries, than those fixed by the ancient moralists seem to us who know what would have been lost had they always been treated with respect.
Thus, so far as was possible in such altered circumstances, did the Renaissance of the second century reproduce the271 intellectual environment from which Plato’s philosophy had sprung. In literature, there was the same attention to words rather than to things; sometimes taking the form of exact scholarship, after the manner of Prodicus; sometimes of loose and superficial declamation, after the manner of Gorgias. There was the naturalism of Hippias, elaborated into a system by the Stoics, and practised as a life by the new Cynics. There was the hedonism of Aristippus, inculcated under a diluted form by the Epicureans. There was the old Ionian materialism, professed by Stoics and Epicureans alike. There was the scepticism of Protagoras, revived by Aenesidêmus and his followers. There was the mathematical mysticism of the Pythagoreans, flourishing in Egypt instead of in southern Italy. There was the purer geometry of the Alexandrian Museum, corresponding to the school of Cyrênê. On all sides, there was a mass of vague moral preaching, without any attempt to exhibit the moral truths which we empirically know as part of a comprehensive metaphysical philosophy. And, lastly, there was an immense undefined religious movement, ranging from theologies which taught the spirituality of God and of the human soul, down to the most irrational and abject superstition. We saw in the last chapter how, corresponding to this environment, there was a revived Platonism, that Platonism was in fact the fashionable philosophy of that age, just as it afterwards became the fashionable philosophy of another Renaissance thirteen centuries later. But it was a Platonism with the backbone of the system taken out. Plato’s thoughts all centred in a carefully considered scheme for the moral and political regeneration of society. Now, with the destruction of Greek independence, and the absorption everywhere of free city-states into a vast military empire, it might seem as if the realisation of such a scheme had become altogether impracticable. The Republic was, indeed, at that moment realising itself under a form adapted to the altered exigencies of the time; but no Platonist could as yet recognise272 in the Christian Church even an approximate fulfilment of his master’s dream. Failing any practical issue, there remained the speculative side of Plato’s teaching. His writings did not embody a complete system, but they offered the materials whence a system could be framed. Here the choice lay between two possible lines of construction; and each had, in fact, been already attempted by his own immediate disciples. One was the Pythagorean method of the Old Academy, what Aristotle contemptuously called the conversion of philosophy into mathematics. We saw in the last chapter how the revived Platonism of the first and second centuries entered once more on the same perilous path, a path which led farther and farther away from the true principles of Greek thought, and of Plato himself when his intellect stood at its highest point of splendour. Neo-Pythagorean mysticism meant an unreconciled dualism of spirit and matter; and as the ultimate consequence of that dualism, it meant the substitution of magical incantations and ceremonial observances for the study of reason and virtue. Moreover, it readily allied itself with Oriental beliefs, which meant a negation of natural law that the Greeks could hardly tolerate, and, under the form of Gnostic pessimism, a belief in the inherent depravity of Nature that they could not tolerate at all.The religious revival initiated by Augustus for his own purposes was soon absorbed and lost in a much wider movement, following independent lines and determined by forces whose existence neither he nor any of his contemporaries could suspect. Even for his own purposes, something more was needed than a mere return to the past. The old Roman faith and worship were too dry and meagre to satisfy the cravings of the Romans themselves in the altered conditions created for them by the possession of a world-wide empire; still less could they furnish a meeting-ground for all the populations which that empire was rapidly fusing into a single mass. But what was wanted might be trusted to evolve itself without any assistance from without, once free scope was given to the religious instincts of mankind. These had long been kept in abeyance by the creeds which they had originally called into existence, and by the rigid political organisation of the ancient city-state. Local patriotism was adverse to the introduction of new beliefs either from within or from without. Once the general interests of a community had been placed under the guardianship of certain deities with definite names and jurisdictions, it was understood that they would feel offended at the prospect of seeing their privileges invaded by a rival power; and were that rival the patron of another community, his introduction might seem like a surrender of national independence at the feet of an alien conqueror. So,203 also, no very active proselytism was likely to be carried on when the adherents of each particular religion believed that its adoption by an alien community would enable strangers and possible enemies to secure a share of the favour which had hitherto been reserved for themselves exclusively. And to allure away the gods of a hostile town by the promise of a new establishment was, in fact, one of the stratagems commonly employed by the general of the besieging army.312
An attempt has recently been made by M. Guyau to trace the influence of Epicurus on modern philosophy. We cannot but think the method of this able and lucid writer a thoroughly118 mistaken one. Assuming the recognition of self-interest as the sole or paramount instinct in human nature, to be the essence of what Epicurus taught, M. Guyau, without more ado, sets down every modern thinker who agrees with him on this one point as his disciple, and then adds to the number all who hold that pleasure is the end of action; thus making out a pretty long list of famous names among the more recent continuators of his tradition. A more extended study of ancient philosophy would have shown the French critic that moralists who, in other respects, were most opposed to Epicurus, agreed with him in holding that every man naturally and necessarily makes his own interest the supreme test of right conduct; and that only with the definition of welfare did their divergence begin. On the other hand, the selfish systems of modern times differ entirely from Epicureanism in their conception of happiness. With Hobbes, for instance, whom M. Guyau classes as an Epicurean, the ideal is not painlessness but power; the desires are, according to his view, naturally infinite, and are held in check, not by philosophical precepts but by mutual restraint; while, in deducing the special virtues, his standard is not the good of each individual, but the good of the whole—in other words, he is, to that extent, a Stoic rather than an Epicurean. La Rochefoucauld, who is offered as another example of the same tendency, was not a moralist at all; and as a psychologist he differs essentially from Epicurus in regarding vanity as always and everywhere the great motive to virtue. Had the Athenian sage believed this he would have despaired of making men happy; for disregard of public opinion, within the limits of personal safety, was, with him, one of the first conditions of a tranquil existence. Nor would he have been less averse from the system of Helvétius, another of his supposed disciples. The principal originality of Helvétius was to insist that the passions, instead of being discouraged—as all previous moralists, Epicurus among the number, had advised—should be119 deliberately stimulated by the promise of unlimited indulgence to those who distinguished themselves by important public services. Of Spinoza we need say nothing, for M. Guyau admits that he was quite as much inspired by Stoic as by Epicurean ideas. At the same time, the combination of these two ethical systems would have been much better illustrated by modern English utilitarianism, which M. Guyau regards as a development of Epicureanism alone. The greatest happiness of the greatest number is not an individual or self-interested, but a universal end, having, as Mill has shown, for its ultimate sanction the love of humanity as a whole, which is an essentially Stoic sentiment. It may be added that utilitarianism has no sympathy with the particular theory of pleasure, whether sensual or negative, adopted by Epicurus. In giving a high, or even the highest place to intellectual enjoyments, it agrees with the estimate of Plato and Aristotle, to which he was so steadily opposed. And in duly appreciating the positive side of all enjoyments, it returns to the earlier hedonism from which he stood so far apart.
Among natural objects, some exist unchanged through all eternity, while others are generated and decay. The former are divinely glorious, but being comparatively inaccessible to our means of observation, far less is known of them than we could wish; while perishable plants and animals offer abundant opportunities of study to us who live under the same conditions with them. Each science has a charm of its own. For knowledge of the heavenly bodies is so sublime a thing that even a little of it is more delightful than all earthly science put together; just as the smallest glimpse of a beloved beauty is more delightful than the fullest and nearest revelation of ordinary objects; while, on the other hand, where there are greater facilities for observation, science can be carried much further; and our closer kinship with the creatures of earth is some compensation for the interest felt in that philosophy which deals with the divine. Wherefore, in our discussions on living beings we shall, so far as possible, pass over nothing, whether it rank high or low in the scale of estimation. For even such of them as displease the senses, when viewed with the eye of reason as wonderful works of Nature afford an inexpressible pleasure to those who can enter philosophically into the causes of things. For, surely, it would be absurd and irrational to look with delight at the images of such objects on account of our interest in the pictorial or plastic skill which they exhibit, and not to take still greater pleasure in a scien311tific explanation of the realities themselves. We ought not then to shrink with childish disgust from an examination of the lower animals, for there is something wonderful in all the works of Nature; and we may repeat what Heracleitus is reported to have said to certain strangers who had come to visit him, but hung back at the door when they saw him warming himself before a fire, bidding them come in boldly, for that there also there were gods; not allowing ourselves to call any creature common or unclean, because there is a kind of natural beauty about them all. For, if anywhere, there is a pervading purpose in the works of Nature, and the realisation of this purpose is the beauty of the thing. But if anyone should look with contempt on the scientific examination of the lower animals, he must have the same opinion about himself; for the greatest repugnance is felt in looking at the parts of which the human body is composed, such as blood, muscles, bones, veins, and the like.193 Similarly, in discussing any part or organ we should consider that it is not for the matter of which it consists that we care, but for the whole form; just as in talking about a house it is not bricks and mortar and wood that we mean; and so the theory of Nature deals with the essential structure of objects, not with the elements which, apart from that structure, would have no existence at all.194
The influence of Aristotle has, indeed, continued to make itself felt not only through the teaching of his modern imitators, but more directly as a living tradition in literature, or through the renewed study of his writings at first hand. Even in the pure sciences, it survived until a comparatively recent period, and, so far as the French intellect goes, it is not yet entirely extinct. From Abélard on, Paris was the headquarters of that soberer scholasticism which took its cue from the Peripatetic logic; and the resulting direction of thought, deeply impressed as it became on the French character and the French language, was interrupted rather than permanently altered by the Cartesian revolution, and, with the fall of Cartesianism, gradually recovered its old predominance. The Aristotelian philosophy is remarkable above all others for clear definitions, full descriptions, comprehensive classifications, lucid reasoning, encyclopaedic science, and disinterested love of knowledge; along with a certain incapacity for ethical speculation,576 strong conservative leanings, and a general tendency towards the rigid demarcation rather than the fruitful commingling of ideas. And it will probably be admitted429 that these are also traits characteristic of French thinking as opposed to English or German thinking. For instance, widely different as is the Mécanique Céleste from the astronomy of Aristotle’s treatise On the Heavens, both agree in being attempts to prove the eternal stability of the celestial system.577 The destructive deluges by which Aristotle supposes civilisation to be periodically interrupted, reappear on a larger scale in the theory of catastrophes still held by French geologists. Another Aristotelian dogma, the fixity of organic species, though vigorously assailed by eminent French naturalists, has, on the whole, triumphed over the opposite doctrine of transformism in France, and now impedes the acceptance of Darwin’s teaching even in circles where theological prepossessions are extinct. The accepted classifications in botany and zoology are the work of Frenchmen following in the footsteps of Aristotle, whose genius for methodical arrangement was signally exemplified in at least one of these departments; the division of animals into vertebrate and invertebrate being originally due to him. Bichat’s distinction between the animal and the vegetable functions recalls Aristotle’s distinction between the sensitive and nutritive souls; while his method of studying the tissues before the organs is prefigured in the treatise on the Parts of Animals. For a long time, the ruling of Aristotle’s Poetics was undisputed in French criticism; and if anything could disentitle Montesquieu’s Esprit des Lois to the proud motto, Prolem sine matre creatam, it would be its close relationship to the Politics of the same universal master. Finally, if it be granted that the enthusiasm for knowledge, irrespective of its utilitarian applications, exists to a greater degree among the educated classes of France than in any other modern society, we may plausibly attribute this honourable characteristic to the fostering influence of one who has430 proclaimed more eloquently than any other philosopher that theoretical activity is the highest good of human life, the ideal of all Nature, and the sole beatitude of God.
In addition to its other great lessons, the Symposium has afforded Plato an opportunity for contrasting his own method of philosophising with pre-Socratic modes of thought. For it consists of a series of discourses in praise of love, so arranged as to typify the manner in which Greek speculation, after beginning with mythology, subsequently advanced to physical theories of phenomena, then passed from the historical to the contemporary method, asking, not whence did things come, but what are they in themselves; and finally arrived at the logical standpoint of analysis, classification, and induction.
The explanation of this anomaly is, we believe, to be found in the fact that Catholicism did, to a great extent, actually spring from a continuation of those widely different tendencies which Epicurus confounded in a common assault. It had an intellectual basis in the Platonic and Stoic philosophies, and a popular basis in the revival of those manifold superstitions which, underlying the brilliant civilisations of Greece and Rome, were always ready to break out with renewed violence when their restraining pressure was removed. The revival of which we speak was powerfully aided from without. The same movement that was carrying Hellenic culture into Asia was bringing Oriental delusions by a sort of back current into the Western world. Nor was this all. The relaxation of all political bonds, together with the indifference of the educated classes, besides allowing a rank undergrowth of popular beliefs to spring up unchecked, surrendered the regulation of those beliefs into the hands of a78 profession which it had hitherto been the policy of every ancient republic to keep under rigid restraint—the accredited or informal ministers of religion.154 Now, the chief characteristic of a priestly order has always and everywhere been insatiable avarice. When forbidden to acquire wealth in their individual capacity, they grasp at it all the more eagerly in their corporate capacity. And, as the Epicureans probably perceived, there is no engine which they can use so effectually for the gratification of this passion as the belief in a future life. What they have to tell about this is often described by themselves and their supporters as a message of joy to the weary and afflicted. But under their treatment it is very far from being a consolatory belief. Dark shades and lurid lights predominate considerably in their pictures of the world beyond the grave; and here, as we shall presently show, they are aided by an irresistible instinct of human nature. On this subject, also, they can speak with unlimited confidence; for, while their other statements about the supernatural are liable to be contradicted by experience, the abode of souls is a bourne from which no traveller returns to disprove the accuracy of their statements.Institute of Plasma Physics, Hefei Institutes of Physical Science (ASIPP, HFIPS) undertakes the procurement package of superconducting conductors, correction coil, superconducting feeder, power supply and diagnosis, accounting for nearly 80% of China's ITER procurement package.
"I am so proud of our team and it’s a great pleasure for me working here," said BAO Liman, an engineer from ASIPP, HFIPS, who was invited to sit near Chinese National flay on the podium at the kick-off ceremony to represent Chinese team. BAO, with some 30 ASIPP engineers, has been working in ITER Tokamak department for more than ten years. Due to the suspended international traveling by COVID-19, most of the Chinese people who are engaged in ITER construction celebrated this important moment at home through live broadcasting.
One of ASIPP’s undertakes, the number 6 poloidal field superconducting coil (or PF6 coil) , the heaviest superconducting coil in the world, was completed last year, and arrived at ITER site this June. PF6 timely manufacturing and delivery made a solid foundation for ITER sub-assembly, it will be installed at the bottom of the ITER cryostat.
Last year, a China-France Consortium in which ASIPP takes a part has won the bid of the first ITER Tokamak Assembly task, TAC-1, a core and important part of the ITER Tokamak assembly.
Exactly as Bernard BIGOT, Director-General of ITER Organization, commented at a press conference after the ceremony, Chinese team was highly regarded for what they have done to ITER project with excellent completion of procurement package.
