On Explanation: Aristotelean and Hempelean :: History Science Scientific Papers

On Explanation Aristotelean and HempeleanABSTRACT Given the great historical distance between scientific explanation as Aristotle and Hempel saw it, I examine and appraise important similarities and differences between the two approaches, especially the lean to take deduction itself as the very model of scientific k straightledge. I argue that we have good reasons to reject this inclination. In his recent studies presentation Galileos knowledge of and adherence to the deductive standards of explanation in science dress circle forth by Aristotle, Wallace (1) remarks that this Aristotelean theory must non be confused with the contemporary deductive-nomological theory of Hempel and Oppenheim. (2) There are, of course, important differences between the incorrupt works of Aristotle and Hempel, for twenty-three centuries trickery between them. But the differences are not as great as might be expected, and, as latest discussions of the metatheoretical issues of explanation are gener ally ahistorical, I believe an attempt to match these two intellectual mileposts in our understanding of scientific method should come erupt useful.The most obvious and interesting similarities between the two metatheories of science lie in their deductive character, and this is where their significant contrasts lie as well. Aristotle had developed two major deductive systems the hypothetical and categorical syllogisms. Of these, he thought unaccompanied when the latter suitable to the demanding rigors of scientific knowledge, whose first characteristics he saw to be certainty and necessity. (3) There are some problematic elements in just what Aristotle took these concepts to mean, unless I postpone discussion of that to a later stage.The categorical syllogism, kind of in the familiar Barbara of the first figure of the first mood, Aristotle sees to be the holy man supplier of both the certainty and the necessity, with the scientific finish being the conclusion of the syllog ism. Like Hempel and Oppenheim, he insists that the premises be true, from which it is evident that the conclusion could not fail to be certainly and necessarily true. The syllogism itself, as an argument, then stands as an explanation. Inasmuch as the deductive system of the categorical syllogism can be seen now to be a significant subset of the first-order predicate calculus, which is the deductive system confirming by Hempel and Oppenheim, the difference between the deductive requirements of the two metatheories is really only that of the greater scope, power, and elegance of the more recent logic. But it remained for Hempel and Oppenheim to point out the
