长久以来,我一直思忖,到底是什么铸就了自由?试想,我正在安装一台高性能设备,但由于手笨眼拙、技不从心,导致机器运转时,零件之间相互干扰,最终只好逼停安检。对于这些零件来说,他们的自由不就是能够实现最优组配及相互契合吗?想要引擎活塞自由运动,不受一点阻力,就需要使零件之间精密配合、完美协作。因此,活塞的自由不是源自放任不管或孤立运行,而是因为它能够与庞大结构中的其他部件巧妙相连、精心运作。

何为自由?有人说就好比火车,它能够自由疾驰。什么意思呢?就是说火车所有零件经过最优组合、调整后,其间的摩擦会降至最小,进而实现完美配置,所以能够自由飞驰。又有人说就好比帆船,常言道:船行水面犹如凌波微步,“看它乘风破浪,多么畅行自由啊!”也就是说,船能完美地借用风力,与上苍之息协同一致,进而扬帆远航。当逆风而行时,伴随着海的音符,船时而屹立于浪尖,时而摇曳在风中,船的每一块材料都在颤抖,船体本身也被撼动,随时都会被风所困。只有待风平浪静,她能再次与外力协同一致,这时她才算是自由了。

人类的自由体现为兴趣、活动、精神三者的完美协调。

First, then, what is science? Surely there can be no difficulty in answering this, and yet I fear that, if I should pass through this or any other audience with the question, I should get many different answers.

A certain lady, whom I know better than any other, has told me that, should she ever be permitted to marry a second time, she would not marry a scientific man, because scientific men are so terribly accurate. I often hear the same general idea expressed, and it is clear that accuracy is one attribute of science according to prevailing opinions. But accuracy alone is not science. When we hear a game of baseball or of whist spoken of as thoroughly scientific, I suppose the idea here, too, is that the games are played accurately; that is, to use the technical expression, without errors.

Again, there are those who seem to think that science is something that has been devised by the Evil One for the purpose of undermining religion. The idea is not so common as it was a few years ago, when the professors of scientific subjects in our colleges were generally objects of suspicion. The change which has come over the world in this respect within my own memory is simply astounding. In general terms, an agreement has been reached between those who represent religion and those who represent science. This agreement is certainly not final, but it gives us a modus vivendi , and the clash of arms is now rarely heard. Religion now takes into consideration the claims of science, and science recognizes the great fundamental truths of religion. Each should strengthen the other, and in time, no doubt, each will strengthen the other.

Probably the idea most commonly held in regard to science is that it is something that gives us a great many useful inventions. The steam engine, the telegraph, the telephone, the trolley car, dyestuffs, medicines, explosives—these are the fruits of science, and without these science is of no avail. I propose farther on to discuss this subject more fully than I can at this stage of my remarks, so that I may pass over it lightly here. I need only say now that useful inventions are not a necessary consequence of scientific work, and that scientific work does not depend upon useful applications for its value. These propositions, which are familiar enough to scientific men, are apt to surprise those who are outside of scientific circles. I hope before I get through to show you that the propositions are true.

Science, then, is not simply accuracy, although it would be worthless if it were not accurate; it is not devised for the purpose of undermining religion; and its object is not the making of useful inventions. Then what is it?

One dictionary gives this definition: “Knowledge; knowledge of principles and causes, ascertained truths or facts … Accumulated and established knowledge which has been systematized and formulated with reference to the discovery of general truths or the operation of general laws, … especially such knowledge when it relates to the physical world, and its phenomena, the nature, constitution, and forces of nature, the qualities and functions of living tissues, etc.”

One writer says
:“The distinction between science and art is that science is a body of principles and deductions to explain the nature of some matter. An art is a body of precepts with practical skill for the completion of some work. A science teaches us to know; an art, to do. In art, truth is means to an end; in science, it is the only end. Hence the practical arts are not to be classed among the sciences.” Another writer says, “Science and art may be said to be investigations of truth; but one, science, inquires for the sake of knowledge; the other, art, for the sake of production;and hence science is more concerned with higher truths, art with the lower; and science never is engaged, as art, is, in productive application.”

Science, then, has for its object the accumulation and systematization of knowledge, the discovery of truth. The astronomer is trying to learn more and more about the celestial bodies, their motions, their composition, their changes. Through his labors, carried on for many centuries, we have the science of astronomy. The geologist has, on the other hand, confined his attention to the earth, and he is trying to learn as much as possible of its composition and structure, and of the processes that have been operating through untold ages to give us the earth as it now is. He has given us the science of geology, which consists of a vast mass of knowledge carefully systematized and of innumerable deductions of interest and value. If the time shall ever come when, through the labor of the geologist, all that can possibly be learned in regard to the structure and development of the earth shall have been learned, the occupation of the geologist would be gone. But that time will never come.

And so I might go on pointing out the general character of the work done by different classes of scientific men, but this would be tedious. We should only have brought home to us in each case the fact that, no matter what the science may be with which we are dealing, its disciples are simply trying to learn all they can in the field in which they are working. As I began with a reference to astronomy, let me close with a reference to chemistry. Astronomy has to deal with the largest bodies and the greatest distances of the universe; chemistry, on the other hand, has to deal with the smallest particles and the shortest distances of the universe. Astronomy is the science of the infinitely great; chemistry is the science of the infinitely little. The chemist wants to know what things are made of and, in order to find this out, he has to push his work to the smallest particles of matter. Then he comes face to face with facts that lead him to the belief that the smallest particles he can weigh by the aid of the most delicate balance, and the smallest particles he can see with the aid of the most powerful microscope, are immense as compared with those of which he has good reason to believe the various kinds of matter to be made up. It is for this reason that I say that chemistry is the science of the infinitely little.

Thus I have tried to show what science is and what it is not.
