    《【今天的彩票图片大全】欢迎访问》Again, whatever harmony evolution may introduce into our conceptions, whatever hopes it may encourage with regard to the future of our race, one does not see precisely what sanction it gives to morality at present—that is to say, how it makes self-sacrifice easier than before. Because certain forces have been unconsciously working towards a certain end through ages past, why should I consciously work towards the same end? If the perfection of humanity is predetermined, my conduct cannot prevent its consummation; if it in any way depends on me, the question returns, why should my particular interests be sacrificed to it? The man who does not already love his contemporaries whom he has seen is unlikely to love them the more for the sake of a remote posterity whom he will never see at all. Finally, it must be remembered that evolution is only half the cosmic process; it is partially conditioned at every stage by dissolution, to which in the long run it must entirely give way; and if, as Mr. Spencer observes, evolution is the more interesting of the two,105 this preference is itself due to the lifeward tendency of our thoughts; in other words, to those moral sentiments which it is sought to base on what, abstractedly considered, has all along been a creation of their own.But if even so little as this remains unproved, what are we to think of the astounding assertion, that ‘Aristotle’s theory of a creative reason, fragmentary as that theory is left, is the answer to all materialistic theories of the universe. To Aristotle, as to a subtle Scottish preacher,264 “the real pre-supposition of all knowledge, or the thought which is the prius of all things, is not the individual’s consciousness of himself as individual, but a thought or self-consciousness which is beyond all individual selves, which is the unity of all individual selves, and their objects, of all thinkers and all objects of thought.”’265 How can materialism or anything else be possibly refuted by a theory which is so obscurely set forth that no two interpreters are able to agree in their explanation of it? And even were it stated with perfect clearness and fulness, how can any hypothesis be refuted by a mere dogmatic declaration of Aristotle? Are we back in the Middle Ages that his ipse dixit is to decide questions now raised with far ampler means of discussion than he could possess? As to Principal Caird’s metaphysics, we have no wish to dispute their theoretic accuracy, and can only admire the liberality of a Church in which propositions so utterly destructive of traditional orthodoxy are allowed to be preached. But one thing we are certain of, and that is, that whether or not they are consistent with Christian theism, they are utterly inconsistent with Aristotelian principles. Which is the ‘thought or self-consciousness’ referred to, a possibility or an actuality? If the former, it is not a prius, nor is it the creative reason. If the latter, it cannot transcend all or any individual selves, for, with Aristotle, individuals are the sole reality, and the supreme being of his system is pre-eminently individual; neither can it unify them, for, according to Aristotle, two things which are two in actuality cannot be one in actuality.266

    Marcus Aurelius, a constant student of Lucretius, seems to have had occasional misgivings with respect to the certainty of his own creed; but they never extended to his practical beliefs. He was determined that, whatever might be the origin of this world, his relation to it should be still the same. ‘Though things be purposeless, act not thou without a purpose.’ ‘If the universe is an ungoverned chaos, be content that in that wild torrent thou hast a governing reason within thyself.’104

    It is in this last conversation that the historical Socrates most nearly resembles the Socrates of Plato’s Apologia. Instead, however, of leaving Euthydêmus to the consciousness of his ignorance, as the latter would have done, he proceeds, in Xenophon’s account, to direct the young man’s studies according to the simplest and clearest principles; and we have another conversation where religious truths are instilled by the same catechetical process.92 Here the erotetic method is evidently a mere didactic artifice, and Socrates could easily have written out his lesson under the form of a regular demonstration. But there is little doubt that in other cases he used it as a means for giving increased precision to his own ideas, and also for testing their validity, that, in a word, the habit of oral communication gave him a familiarity with logical processes which could not otherwise have been acquired. The same cross-examination that acted as a spur on the mind of the respondent, reacted as a bridle on the mind of the interrogator, obliging him to make sure beforehand of every assertion that he put forward, to study the mutual bearings of his beliefs, to analyse them into their component elements, and to examine the relation in which they collectively stood to the opinions generally accepted. It has already been stated that Socrates gave the erotetic method two new applications; we now see in what direction they tended. He made it a vehicle for positive instruction, and he also made it an instrument for self-discipline, a help to fulfilling the Delphic precept, ‘Know thyself.’ The second application was even more important than the first. With us literary training—that is, the practice of continuous reading and composition—is so widely diffused, that conversation has become142 rather a hindrance than a help to the cultivation of argumentative ability. The reverse was true when Socrates lived. Long familiarity with debate was unfavourable to the art of writing; and the speeches in Thucydides show how difficult it was still found to present close reasoning under the form of an uninterrupted exposition. The traditions of conversational thrust and parry survived in rhetorical prose; and the crossed swords of tongue-fence were represented by the bristling chevaux de frise of a laboured antithetical arrangement where every clause received new strength and point from contrast with its opposing neighbour.Meanwhile the morality of Stoicism had enlisted a force of incalculable importance on its behalf. This was the life and death of the younger Cato. However narrow his intellect, however impracticable his principles, however hopeless his resistance to the course of history, Cato had merits which in the eyes of his countrymen placed him even higher than Caesar; and this impression was probably strengthened by the extraordinary want of tact which the great conqueror showed when he insulted the memory of his noblest foe. Pure in an age of corruption, disinterested in an age of greed, devotedly patriotic in an age of selfish ambition, faithful unto death in an age of shameless tergiversation, and withal of singularly mild and gentle character, Cato lived and died for the law of conscience, proving by his example that if a revival of old Roman virtue were still possible, only through the lessons of Greek philosophy could this miracle be wrought. And it was equally clear that Rome could only accept philosophy under a form harmonising with her ancient traditions, and embodying doctrines like those which the martyred saint of her republican liberties had professed.

    That such a tendency was at work some time before the age of Epicurus is shown by the following passage from Plato’s Republic:】【

    Another distinguished compliment was paid to Plotinus after his death by no less an authority than the Pythian Apollo, who at this period had fully recovered the use of his voice. On being consulted respecting the fate of the philosopher’s soul, the god replied by a flood of bombastic twaddle, in which the glorified spirit of Plotinus is described as released from the chain of human necessity and the surging uproar of the body, swimming stoutly to the storm-beaten shore, and mounting the heaven-illumined path, not unknown to him even in life, that leads to the blissful abodes of the immortals.423So strong, however, was the theological reaction against Greek rationalism that Epicurus himself came under its influence. Instead of denying the existence of the gods altogether, or leaving it uncertain like Protagoras, he asserted it in the most emphatic manner. Their interference with Nature was all that he cared to dispute. The egoistic character of his whole system comes out once more in his conception of them as beings too much absorbed in their own placid enjoyments to be troubled with the work of creation and providence. He was, indeed, only repeating aloud what had long been whispered in the free-thinking circles of Athenian society. That the gods were indifferent to human interests81 was a heresy indignantly denounced by Aeschylus,159 maintained by Aristodêmus, the friend of Socrates, and singled out as a fit subject for punishment by Plato. Nor was the theology of Aristotle’s Metaphysics practically distinguishable from such a doctrine. Although essential to the continued existence of the cosmos, considered as a system of movements, the Prime Mover communicates the required impulse by the mere fact of his existence, and apparently without any consciousness of the effect he is producing. Active beneficence had, in truth, even less to do with the ideal of Aristotle than with the ideal of Epicurus, and each philosopher constructed a god after his own image; the one absorbed in perpetual thought, the other, or more properly the others, in perpetual enjoyment; for the Epicurean deities were necessarily conceived as a plurality, that they might not be without the pleasure of friendly conversation. Nevertheless, the part assigned by Aristotle to his god permitted him to offer a much stronger proof of the divine existence and attributes than was possible to Epicurus, who had nothing better to adduce than the universal belief of mankind,—an argument obviously proving too much, since it told, if anything, more powerfully for the interference than for the bare reality of supernatural agents.

    The modern doctrine of evolution, while relying largely on the fertility of multiplied chances, is not obliged to assume such an enormous number of simultaneous coincidences as Epicurus. The ascription of certain definite attractions and repulsions to the ultimate particles of matter would alone restrict their possible modes of aggregation within comparatively narrow limits. Then, again, the world seems to have been built up by successive stages, at each of which some new force or combination of forces came into play, a firm basis having been already secured for whatever variations they were capable of producing. Thus the solar system is a state of equilibrium resulting from the action of two very simple forces, gravitation and heat. On the surface of the earth, cohesion and chemical affinity have been superadded. When a fresh equilibrium had resulted from their joint energy, the more complex conditions of life found free scope for their exercise. The transformations of living species were similarly effected by variation on variation. And, finally, in one species, the satisfaction of its animal wants set free those more refined impulses by which, after many experiments, civilisation has been built up. Obviously the total sum of adaptations necessary to constitute our actual world will have the probabilities of its occurrence enormously increased if we suppose the more general conditions to be established prior to, and in complete independence of, the less general, instead of limiting ourselves, like the ancient atomists, to one vast simultaneous shuffle of all the material and dynamical elements involved.

    It may be urged that beauty, however difficult of attainment or severe in form, is, after all, essentially superficial; and that a morality elaborated on the same principles will be equally superficial—will, in fact, be little more than the art of keeping up appearances, of displaying fine sentiments, of avoiding those actions the consequences of which are immediately felt to be disagreeable, and, above all, of not needlessly wounding anyone’s sensibilities. Such an imitation of morality—which it would be a mistake to call hypocrisy—has no doubt been common enough among all civilised nations; but there is no reason to believe that it was in any way favoured by the circumstances of Greek life. There is even evidence of a contrary tendency, as, indeed, might be expected among a people whose most important states were saved from the corrupt60ing influences of a court. Where the sympathetic admiration of shallow and excitable spectators is the effect chiefly sought after, the showy virtues will be preferred to the solid, and the appearance to the reality of all virtue; while brilliant and popular qualities will be allowed to atone for the most atrocious crimes. But, among the Greeks of the best period, courage and generosity rank distinctly lower than temperance and justice; their poets and moralists alike inculcate the preference of substance to show; and in no single instance, so far as we can judge, did they, as modern nations often do, for the sake of great achievements condone great wrongs. It was said of a Greek and by a Greek that he did not wish to seem but to be just.46 We follow the judgment of the Greeks themselves in preferring Leonidas to Pausanias, Aristeides to Themistocles, and Socrates to Alcibiades. And we need only compare Epameinondas with David or Pericles with Solomon as national heroes, to perceive at once how much nearer the two Greeks come to our own standard of perfection, and how futile are the charges sometimes brought against those from whose traditions we have inherited their august and stainless fame.

    But Epicurus could only borrow the leading principle of his opponents at the expense of an enormous inconsistency. It was long ago pointed out by the Academicians—and the objection has never been answered—that pleasure and mere painlessness cannot both be the highest good, although the one may be an indispensable condition of the other. To confound the means with the end was, indeed, a common fault of Greek philosophy; and the Stoics also were guilty of it when they defined self-preservation to be the natural object of every creature, and yet attached a higher value to the instruments than to the aims of that activity. In Epicureanism, however, the change of front was more open, and was attempted under the eyes of acute and vigilant enemies. If the total absence of pain involves a pleasurable state of consciousness, we have a right to ask for a definition or description of it, and this, so far as can be made out, our philosopher never pretended to supply. Of course, a modern psychologist can point out that the functions of respiration, circulation, secretion, and absorption are constantly going on, and that, in their normal activity, they give rise to a vast sum of pleasurable consciousness, which far more than makes up in volume for what it wants in acuteness. But, whatever his recent interpreters may say,133 Epicurus nowhere alludes to this diffused feeling of vitality; had he recognised it, his enumeration of the positive sensations, apart from which the good is inconceivable, would have seemed as incomplete to him as it does to us. If, on the other hand, the complete removal of pain introduces us to a state of consciousness, which, without being positively pleasurable, has a positive value of some kind, we ought to be told wherein it differs from the ideals of the spiritualist school;66 while, if it has no positive value at all, we ought equally to be told wherein it differs from the unconsciousness of sleep or of death.

    It has been already shown how Extension, having become identified with matter, took on its mechanical qualities, and was conceived as a connected series of causes or modes of motion. The parallel found by Spinoza for this series in Thought is the chain of reasons and consequents forming a410 demonstrative argument; and here he is obviously following Aristotle, who although ostensibly distinguishing between formal and efficient causes, hopelessly confounds them in the second book of his Posterior Analytics.565 We are said to understand a thing when we bring it under a general rule, and also when we discover the mechanical agency which produces it. For instance, we may know that a particular man will die, either from the fact that all men are mortal, or from the fact that he has received a fatal wound. The general rule, however, is not the cause of what will happen, but only the cause of our knowing that it will happen; and knowledge of the rule by no means carries with it a knowledge of the efficient cause; as we see in the case of gravitation and other natural forces whose modus operandi is still a complete mystery. What deceived Aristotle was partly his false analysis of the syllogism, which he interpreted as the connexion of two terms by the interposition of a middle answering to the causal nexus of two phenomena; and partly his conception of the universe as a series of concentric spheres, through which movement is transmitted from without, thus combining the two ideas of notional comprehension and mechanical causation.

    The parallel between Aenesidêmus and Protagoras would become still more complete were it true that the Alexandrian philosopher also sought to base his Scepticism on the Heracleitean theory of Nature, arguing that contradictory assertions are necessitated by the presence of contradictory properties in every object.

    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.
