单选题Is athletic expertise attained or innate? Those who have suffered the tongue-lashing of a cruel games master at school might be forgiven for doubting the idea that anyone and everyone is capable of great sporting achievement, if only they would put enough effort into it. Practice may make perfect, but not all are built in ways that make it worth bothering in the first place. The latest evidence of this truth has been gathered by Sabrina Lee of Simon Fraser University in Vancouver and Stephen Piazza at Pennsylvania State University. They have looked at the physical structure of short-distance runners and found that their feet are built differently from those ofcouch potatoes. Dr. Lee and Dr. Piazza already knew that short-distance runners tend to have a higher proportion of fast-contracting muscle fibres in their legs than more sedentary folk can muster. They suspected, though, that they would find differences in the bone structure as well. And they did. They looked at seven university sprinters who specialize in the 100-metre dash and five 200-metre specialists, and compared them with 12 non-athletic university students of the same height. In particular, they looked at the sizes of bones of the toes and heel. They also used ultrasonic scanning to measure the sliding motion of the Achilles tendons of their volunteers as their feet moved up and down. This allowed them to study the length of the lever created by the tendon as it pulls on the back of the heel to make the foot flex and push off the ground. Dr. Lee and Dr. Piazza found that the toes of their short-distance runners averaged 8.2cm in length, while those of common people averaged 7.3cm. The length of the lever of bone that the Achilles tendon pulls on also differed, being a quarter shorter in short-distance runners. These findings suggest short-distance runners get better contact with the ground by having longer toes. That makes sense, as it creates a firmer platform to push against. In a short-distance running race, acceleration off the block is everything. Cheetahs, the champion of short-distance runners of the animal kingdom, have non-flexible claws that give a similar advantage. It is possible—just—that the differences in physical structure are the result of long and rigorous training. But it is unlikely. Far more probable is that the old saying of coaches, that great short-distance runners are born not made, is true. Everyone else, games masters included, should just get used to the idea.

单选题The decades after 1830 were a period of disintegration and uncertainty in German philosophy. For almost half a century idealist philosophies, culminating in Hegel's grandiose system, had dominated the philosophical scene, revolving around such spiritual notions as transcendental ego, consciousness, presentation(Vorstellung), idea, mind, and spirit(Geist). The rapid collapse of German Idealism—that "gigantic mountain range" of creative thought, as Husserl called it in 1917, was due to a combination of causes. There was in the first place, accelerated progress in the natural sciences, ranging from physiology(Johannes Muller, Ernst Weber)to physics(Robert Mayer, Hermann Helmholtz)and chemistry(Justus von Liebig, Friedrich Wohler). The success of the experimental approach visibly demonstrated the futility of all idealistic speculation about nature. Secondly, there was the rapid growth of technology(especially the construction of railways and the invention of the telegraph), combined with the process of industrialization(resulting in tensions between capital and labour which led to radical changes in the economic system). Moreover, new political ideas concerning popular participation in government led first of all to the abortive revolution of 1848 and resulted finally in the unification of Germany after the war of 1866. Next to philosophical idealism, the other great loser in this course of events was Christianity, especially protestant Christianity, a long-standing ally of idealism. The vacuum thus produced was often filled by vulgar materialist ideas along the line of Ludwig Buchner's Kraft und Stoff(1855). The more educated classes, however, had needs of a more refined nature, and they turned instead to Schopenhauerianism. Schopenhauer stood firmly in the great European tradition of idealism extending from Plato and Kant, but he nevertheless resolutely rejected post-Kantian, and more specifically Hegelian idealism. Schopenhauer combined the scientist's conviction of a blind causality reigning in the world of nature with a view according to which this world is none the less rooted in a subjective bestowal of sense. He combined the democratic feeling of compassion for all mankind with an elitist view on art, and a belief in the ultimate meaninglessness of history with an ontology in which the will is fundamental. But above all his philosophy, while rating Christianity rather low, made room for religion on better soil; the religion of India. The view of Indian thought current among educated circles in the second half of the nineteenth century in Germany was strongly influenced by Schopenhauer. Not only did he give popular currency to expressions such as "nirvana" and "the veil of maya", but also he may also be held responsible for the current amalgamation of all ideas which blew into Europe from the East. Neither Hinduism and Buddhism nor Brahmanism and Vedanta philosophy were clearly distinguished by Schopenhauer. On one point, however, he was particularly firm: Buddhism is the highest religion in the world, because it is an "atheistic religion" .Thus it not only surpasses Christian theism, but also comes close to Schopenhauer's own conception of the absolute. Schopenhauer's followers in Germany were therefore able to look down on the parochial Christian rituals practised in their country, while upholding the claim that they, too, were directed toward some higher entity however, vaguely conceived. Moreover, they could feel themselves close to the Vedas and Up-anisads, considered to be the oldest and most venerable documents of human thought, while at the same time feeling superior to these Indian "myths" as a result of their own ro-otedness in the purely philosophical ideas of the Schopenhauerian system. To illustrate all this, I want to quote from a document which not only exemplifies this widespread attitude, but also deviates from it in a significant way. It will moreover display the typical framework of Husserl's own understanding of Indian thought. The document in question is a letter written by Thomas Masaryk(1850—1937)in 1876, while Masaryk(who later was to rise to fame as the thunder and first president of the Czechoslovakian state)was still a student of philosophy. The letter is addressed to Franz Brentano who had been for some years Masaryk's teacher at the University of Vienna, the capital of the Aus-tro-Hungarian Empire. It was written from Leipzig in Germany where Masaryk moved in order to continue his studies. On 23 November 1876, he writes to Brentano: ...
