是同义词。美国人待人友善,但这并不意味着发展友谊,暂短的接触并不表明将来愿意继续保持联系。只有当人们拥有共同的兴趣、爱好和共同的人生观时,持久的友谊才有可能发展。美国社会高度的流动性也是造成人们不能保持长久友谊的原因之一。

there no thinking without the use of language, namely in concepts and concept combinations for which words need not necessarily come to mind? Has not every one of us struggled for words although the connection between "things" was already clear?
(111) We might be inclined to attribute to the act of thinking complete independence from language if the individual formed or were able to form. his concepts without the verbal guidance of his environment. Yet most likely the mental shape of an individual, growing up under such conditions, would be very poor. Thus we may conclude that the mental development of the individual and his way of forming concepts depend to a high degree upon language. This makes us realize to what extent the same language means the same mentality. IQ this sense thinking and language are linked together.
What distinguishes the language of science from languages as we ordinarily understand the word? How is it that scientific language is international? (112) What science strives for is an outmost acuteness and clarity of concepts as regards their mutual relation and their correspondence to sensory data. As an illustration, let us take the language of Euclidean geometry and Algebra. They manipulate with a small number of independently introduced concepts, respectively symbols, such as the integral number, the straight line, the point, as well as with signs which designate the fundamental concepts. This is the basis for the construction, respectively definition of all other statements and concepts. The connection between concepts and statements on the one hand and the sensory data on the other hand is established through acts of counting and measuring whose performance is sufficiently well determined.
(113) The super-national character of scientific concepts and scientific language is due to the fact that they have been set up by the best brains of an countries and all times. In solitude and yet in cooperative effort as regards the final effect they created the spiritual tools for the technical revolutions which have transformed the life of mankind in the last centuries. Their system of concepts has served as a guide in the bewildering chaos of perceptions so that we learned to grasp general truths from particular observations.
What hopes and fears does the scientific method imply for mankind? I do not think that this is the right way to put the question. Whatever this tool in the hand of man will produce depends entirely on the nature of the goals alive in this mankind. Once these goals exist, the scientific method furnishes means to realize them. Yet it cannot furnish the very goals. (114) The scientific method itself would not have led anywhere, it would not even have been born without a passionate striving for clear understanding.
Perfection of means and confusion of goals seem—in my opinion—to characterize our age. (115) If we desire sincerely and passionately the safety, the welfare and the free development of the talents of all men we shall not be in want of the means to approach such a state. Even if only a small part of mankind strives for such goals, their superiority will prove itself in the long run.

silent; in others recorded lullabies were played. In others a ticking metronome was operating at the heart-beat speed of 72 beats per minute. In still others the heart-beat recording itself was played. It was then checked to see which groups fell asleep more quickly. The heart-beat group dropped off in half the time it took for any of the other groups. This not only clinches the idea that the sound of the heart beating is a powerfully calming stimulus, but it also shows that the response is a highly specific one. The metronome imitation will not do—at least, not for young infants. So it seems fairly certain that this is the explanation of the mother's left-side approach to baby-holding. It is interesting that when 466 Madonna and child paintings (dating back over several hundred years) were analyzed for this feature, 373 of them showed the baby on the left breast. Here again the figure was at the 80 per cent level. This contrasts with observations of females carrying parcels, where it was found that 50 per cent carried them on the left and 50 per cent on the right.
What other possible results could this heart-beat imprinting have? It may, for example, explain why we insist on locating feelings of love in the heart rather than the head. As the song says: "You gotta have a heart!" It may also explain why mothers rock their babies to lull them to sleep. The rocking motion is carried on at about the same speed as the heart-beat, and once again it probably 'reminds' the infants of the rhythmic sensations they became so familiar with inside the womb, as the great heart of the mother pumped and thumped away above them.
