To explain the phenomena in the world of our experience, to answer the question “why?” rather than only the question “what?”, is one of the foremost objectives of all rational inquiry; and especially, scientific research in its various branches strives to go beyond a mere description of its subject matter by providing an explanation of the phenomena it investigates. While there is rather general agreement about this chief objective of science, there exists considerable difference of opinion as to the function (...) and the essential characteristics of scientific explanation. In the present essay, an attempt will be made to shed some light on these issues by means of an elementary survey of the basic pattern of scientific explanation and a subsequent more rigorous analysis of the concept of law and of the logical structure of explanatory arguments.

Toulmin’s formulation of “analytic arguments” in his 1958 book, The Uses of Argument, is opaque. Commentators have not adequately explicated this formulation, though Toulmin called it a “key” and “crucial” concept for his model of argument macrostructure. Toulmin’s principle “tests” for determining analytic arguments are problematic. Neither the “tautology test” nor the “verification test” straightforwardly indicates whether an argument is analytic or not. As such, Toulmin’s notion of analytic arguments might not represent such a key feature of his model. Absent (...) a clearer formulation of analytic arguments, readers of Toulmin should be hesitant to adopt this terminology. (shrink)

In his The Uses of Argument (Cambridge University Press, 1958), S. Toulmin presents serious charges against ordinary logical theory, e.g., that it does not distinguish between analytic or formally valid or conclusive or warrant-using arguments, that the distinction between premises and conclusion is a bad oversimplification, that "major premise" conceals the distinction between inference-warrant and inference-backings, that logicians have been mistakenly working under an ideal of geometrical form. The paper argues that none of the charges is proven, that most of (...) them cannot be proven, that Toulmin's new logic is at best only vaguely hinted at and that his suggestions are positively obscure or mistaken.

Gilbert Ryle's book The Concept of Mind was published in 1949. According to Ryle, his "destructive purpose" was to show that "a family of radical category mistakes" is the source of the "official doctrine," that is, a "double-life theory," according to which "with the doubtful exception of idiots and infants in arms every human being has both a body and a mind." By numerous examples, Ryle showed quite forcefully how psychology and philosophy at the time were misled into asking the (...) wrong kinds of questions. More than 50 years have elapsed since the original publication of Gilbert Ryle's book and, as Ullin T. Place wrote shortly before passing away, Ryle's conceptual analysis is now due, if not overdue, for a comeback. The purpose of this paper is to discuss the persistent relevance of category mistakes to current problems in the analysis of behavior. (shrink)
