The subject of a science is never well circumscribed and there is little use sharpening its definition. However, nobody will deny that physics deals with nature and sociology with human society in some of their aspects. With logic, it is another matter. Logic is usually understood nowadays as a study of certain formal systems, though in former times there were philosophers who held that the subject matter of logic was the formal rules of human thought. In the latter sense it would be an empirical rather than a formal science, though its empirical subject matter would still be fundamentally different from that of psychology of thinking. One interpretation of logic does not exclude the other. Formal approaches are often easier than empirical ones, and for this reason one can understand why logic as a study of formal systems has till now made more progress than logic as a study of the formal rules of thought, even if restricted to scientific thought.

Many psychologists, sociologists and especially anthropologists and psychiatrists raise serious objections against routine attempts to "extend the methods of the of the physical sciences" to the study of man. These objections cannot be dismissed simply on the grounds that they are not constructive; for inherent in the objections may well be a conviction that there can never be a "behavioral science" as scientists understand science. Whether there can be such a science or not will be decided neither by citing successful applications of "scientific method" to carefully circumscribed sectors of human behavior nor by pointing out what has not yet been done. Therefore on the question of whether a behavioral science can in principle be constructed, we shall take no sides. That some kinds of human behavior can be described and even predicted in terms of objectively verifiable and quantifiable data seems to us to have been established.

We may observe, that, notwithstanding the dogmatical, imperious style of all superstition, the conviction of the religionists, in all ages, is more affected than real, and scarcely ever approaches, in any degree, to that solid belief and persuasion, which governs us in the common affairs of life. Men dare not avow, even to their own hearts, the doubts which they entertain on such subjects: They make a merit of implicit faith; and disguise to themselves their real infidelity, by the strongest asseverations and most positive bigotry. But nature is too hard for all their endeavours, and suffers not the obscure, glimmering light, afforded in those shadowy regions, to equal the strong impressions, made by common sense and by experience. The usual course of men's conduct belies their words, and shows, that their assent in these matters is some unaccountable operation of the mind between disbelief and conviction, but approaching much nearer to the former than to the latter.
David Hume
Unfortunately... the philosophy of Aristotle laid it down as a principle, that the celestial motions were regulated by laws proper to themselves, and bearing no affinity to those which prevail on earth. By thus drawing a broad and impassable line of separation between celestial and terrestrial mechanics, it placed the former altogether out of the pale of experimental research, while it at the same time impeded the progress of the latter by the assumption of principles respecting natural and unnatural motions, hastily adopted from the most superficial and cursory and remark, undeserving even the name of observation. Astronomy therefore continued for ages a science of mere record, in which theory had no part, except in so far as it attempted to conciliate the inequalities of the celestial motions with that assumed law of uniform circular revolution which was alone considered consistent with the perfection of the heavenly mechanism.

I also knew the formula that expresses the energy distribution in the normal spectrum. A theoretical interpretation therefore had to be found at any cost, no matter how high. It was clear to me that classical physics could offer no solution to this problem, and would have meant that all energy would eventually transfer from matter to radiation. ...This approach was opened to me by maintaining the two laws of thermodynamics. The two laws, it seems to me, must be upheld under all circumstances. For the rest, I was ready to sacrifice every one of my previous convictions about physical laws. ...[One] finds that the continuous loss of energy into radiation can be prevented by assuming that energy is forced at the outset to remain together in certain quanta. This was purely a formal assumption and I really did not give it much thought except that no matter what the cost, I must bring about a positive result.

Human dignity has long been understood in this country to be innate. When the framers proclaimed in the Declaration of Independence that 'all men are created equal' and 'endowed by their Creator with certain unalienable Rights', they referred to a vision of mankind in which all humans are created in the image of God and therefore of inherent worth. That vision is the foundation upon which this nation was built. The corollary of that principle is that human dignity cannot be taken away by the government. Slaves did not lose their dignity, any more than they lost their humanity, because the government allowed them to be enslaved. Those held in internment camps did not lose their dignity because the government confined them. And those denied governmental benefits certainly do not lose their dignity because the government denies them those benefits. The government cannot bestow dignity, and it cannot take it away.
