Cryptic coloring is by far the commonest use of color in the struggle for existence. It is
employed for the purpose of attack (aggressive resemblance or anticryptic coloring) as well as of defense (protective resemblance or procryptic coloring). The fact that the same method concealment, may be used both for attack and defense has been well explained by T. Belt who suggests as an illustration the rapidity of movement which is also made use of by both pursuer and pursued, which is similarly raised to a maximum in both by the gradual dying out of the slowest through a series of generations. Cryptic coloring is commonly associated with other aids in the struggle for life. Thus well-concealed mammals and birds, when discovered, will generally endeavor to escape by speed and will often attempt to defend themselves actively. On the other hand, small animals which have no means of active defense, such as large, numbers of insects, frequently depend upon concealment alone. Protective resemblance is far commoner among animals than aggressive resemblance, in correspondence with the fact that predaceous forms are as a rule much larger and much less numerous than their prey. In the case of insectivorous Vertebrata and their prey such differences exist in an exaggerated form. Cryptic coloring, whether used for defense of attack, may be either general or special. In general resemblance the animal, in consequence of its coloring, produces the same effect as its environment, but the conditions do not require any special adaptation of shape and outline. General resemblance is especially common among the animal inhabiting some uniformly colored expanse of the earth's surface, such as an ocean or a desert. In the former, animals of all shapes are frequently protected by their transparent blue color, on the latter, equally diverse forms are defended by their sandy appearance. The effect of a uniform. appearance may be produced by a combination of tints in startling contrast. Thus the black and white stripes of the zebra blend together at a little distance, and "their proportion is such as exactly to match the pale tint which arid ground possesses when seen by moonlight." Special resemblance is far commoner than general and is the form. which is usually met with on the diversified surface of the earth, on the shores, and in shallow water, as well as on the floating masses of algae on the surface of the ocean, such as the Sargasso Sea. In these environments the cryptic coloring of animals is usually aided by special modifications of shape, and by the instinct which leads them to assume particular attitudes. Complete stillness and the assumption of a certain attitude play an essential part in general resemblance on land; but in special resemblance the attitude is often highly specialized, and perhaps more important than any other element in the complex method by which concealment is effected. In special resemblance the combination of coloring, shape, and attitude is such as to produce a more or less exact resemblance to some one of the objects in the environment, such as a leaf of twig, a patch of lichen, a flake of bark. In all cases the resemblance is to some object which is of no interest to the enemy or prey respectively. The animal is not hidden from view by becoming indistinguishable from its background as in the case of general resemblance, but it is mistaken for some well-known object.

In seeking the interpretation of these most interesting and elaborate adaptations, attempts have been made along two lines. The first seeks to explain the effect as a result of the direct influence of the environment upon the individual (G. L. L. Buffon), or by the inherited effects of efforts and the use and disuse of parts (J. B. P. Lamarck). The second believes that natural selection produced the result and afterwards maintained it by the survival of the best concealed in each generation. The former suggestion breaks down when the complex na

【简答题】Religion and Rationality Yet the differenc...

【简答题】Religion and Rationality Yet the difference in tome and language must strike us, so soon as it is philosophy that speaks: that change should remind usthat even if the function of religion and that of reason coincide,this function is performed in the two cases by very different organs. Religions are many, reason one. Religion consists of conscious ideas, hopes, enthusiasms, and objects of worship; it operates by grace and flourishes by prayer. Reason, on the other hand, is a mere principle or potential order, on which indeed we may come to reflect but which exists in us ideally only, without variation or stress of any kind. We conform or do not conform to it; it does not urge or chide us, not call for any emotions on our part other than those naturally aroused by the various objects which it unfolds in their true nature and proportion.Religion brings some order into life by weighting it with new materials. Reason adds to the natural materials only the perfect order which it introduces into them. Rationality is nothing but a form, anideal constitution which experience may more or less embody. Religion is a part of experience itself,a mass of sentiments and ideas. The one is an inviolate principle, the other a changing and struggling force. And yet this struggling and changing force of religion seems to direct man toward something eternal. It seems to make for an ultimate harmony within the soul and for an ultimate harmony between the soul and all that the soul depends upon. Religion, in its intent, is a more conscious and direct pursuit of the Life of Reason than is society, science, or art, for these approach and fill out the ideal life tentatively and piecemeal, hardly regarding the foal or caring forthe ultimate justification of the instinctive aims. Religion also has an instinctive and blind side and bubbles up in all manner of chance practices and intuitions; soon, however, it feels its way towardthe heart of things, and from whatever quarter it may come, veers in the direction of the ultimate. Nevertheless, we must confess that this religious pursuit of the Life of Reason has been singularly abortive. Those within the pale of each religion may prevail upon themselves, to express satisfaction with its results, thanks to a fond partiality in reading the past and generous draughts of hope for the future; but any one regarding the various religions at once and comparing their achievements with what reason requires, must feel how terrible is the disappointment which they have one and all prepared for mankind. Their chief anxiety has been to offer imaginary remediesfor mortal ills, some of which are incurable essentially, while others might have been really cured bywell-directed effort. The Greed oracles, for instance, pretended to heal out natural ignorance, whichhas its appropriate though difficult cure, while the Christian vision of heaven pretended to be anantidote to our natural death—the inevitable correlate of birth and of a changing and conditioned existence. By methods of this sort little can be done for the real betterment of life. To confuse intelligence and dislocate sentiment by gratuitous fictions is a short-sighted way of pursuing happiness. Nature is soon avenged. An unhealthy exaltation and a one-sided morality have to befollowed by regrettable reactions. When these come. The real rewards of life may seem vain to arelaxed vitality, and the very name of virtue may irritate young spirits untrained in and natural excellence. Thus religion too often debauches the morality it comes to sanction and impedes the science it ought to fulfill. What is the secret of this ineptitude? Why does religion, so near to rationality in its purpose, fall soshort of it in its results? The answer is easy; religion pursues rationality through the imagination.When it explains events or assigns causes, it is an imaginative substitute for science. When it gives precepts, insinuates ideals, or remoulds aspiration, it is an imaginative substitute for wisdom—Imean for the deliberate and impartial pursuit of all food. The condition and the aims of life are both represented in religion poetically, but this poetry tends to arrogate to itself literal truth and moral authority, neither of which it possesses. Hence the depth and importance of religion becomes intelligible no less than its contradictions and practical disasters. Its object is the same as that ofreason, but its method is to proceed by intuition and by unchecked poetical conceits. 1. As used in the passage, the author would define “wisdom” as [A] the pursuit of rationality through imagination. [B] an unemotional search for the truth. [C] a purposeful and unbiased quest for what is best. [D] a short-sighted way of pursuing happiness 2. Which of the following statements is NOT TRUE? [A] Religion seeks the truth through imagination, reason, in its search, utilizes the emotions. [B] Religion has proved an ineffective tool in solving man’s problems. [C] Science seeks a piece meal solution to man’s questions. [D] The functions of philosophy and reason are the same. 3. According to the author, science differs from religion in that [A] it is unaware of ultimate goals. [B] it is unimaginative. [C] its findings are exact and final. [D] it resembles society and art. 4. The author states that religion differs from rationality in that [A] it relies on intuition rather than reasoning . [B] it is not concerned with the ultimate justification of its instinctive aims. [C] it has disappointed mankind. [D] it has inspired mankind. 5. According to the author, the pursuit of religion has proved to be [A] imaginative. [B] a provider of hope for the future. [C] a highly intellectual activity [D] ineffectual. Cryptic Coloring Cryptic coloring is by far the commonest use of color in the struggle for existence. It is employed for the purpose of attack (aggressive resemblance or anticryptic coloring ) as well as of defense (protective resemblance or procryptic coloring ). The fact that the same method concealment, may be used both for attack and defense has been well explained by T.Belt who suggests as an illustration the rapidity of movement which is also made use of by both pursuer and pursued, which is similarly raised to a maximum in both by the gradual dying out of the slowest through a series of generations.

Protective resemblance is far commoner among animals than aggressive resemblance, in correspondence with the fact that predaceous forms are as a rule much larger and much less numerous than their prey. In the case of insectivorous Vertebrata and their prey such differences exist in an exaggerated form. Cryptic coloring, whether used for defense of attack, may be either general or special. In general resemblance the animal, in consequence of its coloring, produces the same effect as its environment, but the conditions do not require any special adaptation of shape and outline.

The second believes that natural selection produced the result and afterwards maintained it by the survival of the best concealed in each generation. The former suggestion breaks down when the complex nature of numerous special resemblances is appreciated. Thus the arrangement of colors of many kinds into an appropriate pattern requires the cooperation of a suitable shape and the rigidly exact adoption of a certain elaborate attitude. The latter is instinctive and thus depends on the central nervous system. The cryptic effect is due to the exact cooperation of all these factors; and in the present state of science, the only possible hole of an interpretation lies in the theory of natural selection, which can accumulate any and every variation which tends toward survival. A few of the chief types of methods by which concealment is effected may be briefly described. The colors of large numbers of vertebrate animals are darkest on the back and become gradually lighter on the sides, passing into white on the belly. Abbot H. Thayer has suggested that this gradation obliterates the appearance of solidity, which is due to shadow. The color harmony, which is also essential to concealment, is produced because the back is of the same tint as the environment (e. g. earth), bathed in the cold blue-white of the sky, while the belly, being cold blue-white and bathed in shadow and yellow earth reflections produces the same effects. This method of neutralizing shadow for the purpose of concealment by increased lightness of tint was first suggested by E.B.Poulton in the case of a larva and a pupa, but he did not appreciate the great importance of the principle. In an analogous method an animal in front of a background of dark shadow may have part of its body obliterated by the existence of a dark tint, the remainder resembling, e.g., a part of a leaf. This method of rendering invisible any part which would interfere with the resemblance is well know in mimicry. 1. The black and white stripes of the zebra are most useful form [A] hunters. [B] nocturnal predators [C] lions and tigers. [C] insectivorous Vertrbrata 2. Aggressive resemblance occurs when [A] a predaceous attitude is assumed. [B] special resemblance is utilized. [C] an animal relies on speed. [D] an animal blends in with its background. 3. Special resemblance differs from general resemblance in that the animal relies on [A] its ability to frighten its adversary. [B] speed. [C] its ability to assume an attitude. [D] mistaken identify 4. The title below that best expresses the ides of this passage is [A] Cryptic coloration for Protection. [B] How Animals Survive. [C] The uses of Mimicry in Nature. [D] Resemblances of Animals.
