On the Training of Scientists; D. Steward

ON THE TRAINING OF SCIENTISTS AND MORAL RESPONSIBILITY tv ::DanielJ(' Stewart IN RECENT YEARS there has been much soul-searching among science people over the possible moral conse quences of their work. The scientist of today is genu inely concerned over the obligations that he-as a sci entist-has to his society, and the effect of his discoveries on his fellows. The term "obligations" necessarily implies a reference to some moral standard. And, up to now, moral stand ards, and their necessary implications, have not been one of the major concerns of empirical scientists. The status of moral values in the universe has been a central question in the thought of those who are in the main stream of our philosophical tradition from Plato on down. Moral values are nonphysical and thus cannot be subject to any quantitative tests, but for the typical scientists of the late nineteenth and early twen tieth centuries, whatever is not reducible to some physi calistic verification basis is unreal.

Within this frame of reference, what happens to the scientist who feels some sort of obligation to his society? Any consideration of an obligation necessarily implies the existence of some moral philosophy. But any view which permits moral propositions is, of necessity, in compatible with materialism. Plato makes this distinction unmistakably clear in the dialogue, "The Sophist."l The Eleatic Stranger describes the materialists as "dragging down all things from heaven and from the unseen to earth, and they literally grasp in their hands rocks and oaks; of these they lay hold, and obstinately maintain, that the things only which can be touched or handled have being or essence, be cause they define being and body as one, and if anyone else says that what is not a body exists they altogether despise him, and will hear of nothing but body."

As opposed to this, the idealists are described as "con tending that true essence consists of certain intelligible and incorporeal ideas; the bodies of the materialists" are taken to be "not essence, but generation and motion." The dilemma is quite apparent. The young scientist either accepts the materialistic philosophy of his group; or, sensing the inadequacy of materialism to fully ex plain. nature, he tries to pick up, in a most unscientific 1 Plato, The Dialogues, tr. by B. Jowett. New York: Random House, 1937. Vol. II, pp. 253-254.

But, if the philosophical climate-of-opinion in sci ence is such as to embrace materialism to the exclusion of any philosophy which makes reference to spiritual realities, then what is the prognosis for those recalcitrant souls of the scientific brotherhood who dare to deviate from the unwritten code to the point of even being concerned about a· scientist's obligations to his society? Obligations, and the moral propositions which they necessarily entail, are defined as meaningless in terms of most present-day philosophies of science. It is thought that these propositions have nothing at all to do with genuine science. They belong instead to the realm of traditional philosophy, or worse yet, to religion, and are subject to all the alleged mysticisms of these pursuits. Pitfalls of Materialism Thus, it might reasonably be thought that those sci entists who accept materialism as the basis for their philosophy of nature would not concern themselves with the sociological implications of their activities. In their system man is just a curious sort of an animal. He has little sense of morality or beauty or justice or goodness.
