In lieu of an abstract, here is a brief excerpt of the content:GROUNDING THE HUMAN CONVERSATION Introduction ANTHONY M. MATTEO Elizabethtown Oollege Elizabethtown, Pennsylvania SINCE THE APPEARENCE of Thomas Kuhn's The Structure of Scientific Revolutions 1 the so called "rationality debate " has been conducted at a high pitch in Anglo-American philosophy. Concurrently, this debate has occupied some of the luminaries of Continental philosophy: Gadamer, Habermas, Feyerabend, and Derrida. Now that the Sturm und Drang associated with it has to some (...) extent subsided, we would like to offer a partial analysis and critique. of the insights that this controversy has proffered. In this essay our fundamental thesis is twofold: I) At the heart of the rationality debate is a longing to deconstruct narrow and restrictive methodologies.for acquiring knowledge, thereby creating the possibility for a free and open " human conversation," unfettered by the dogmatisms of the past; ~) The " deconstructive " phase of the deba.te now requires an essentially "constructive " complement: further conditions necessary to ground a free and open " human conversation " need to be specified. In this latter ta.sk we will suggest that the work of the contemporary analytic philosopher, A. C. Grayling, and that of the fa:ther of Transcendental Thomism, Joseph Marecha.I, can be particularly helpful. I ncommensurability The most radical claim to emerge from the recent rationality debate is that of" incommensura.bility ": namely, two or more awropriations of reality can be so utterly diverse that we can1 (Chicago: University of Chicago Press, 1962). 285 ANTHONY M. MATTEO not adjudicate between them as to their respective truth or falsity. Take at face value, for example, Paul Feyerabend's proclamation: that the views of scientists, and especially their views on basic matters, are often as different from each other as are the ideologies that underlie different cultures. Even worse: there exist scientific theories which are mutually incommensurable though they apparently deal " with the same subject matter." 2 Underlying :this claim is the belief that there is no a prori limit to the number of independent ways in which the stuff of reality can be conceived. Furthermore, since there is no atemporal or ahistorical standpoint beyond the fray of contending worldviews, no one view can legitimately demand absolute cognitive priority on the grounds that it more faithfully captures the " essence " of things than any other possible alternative. In effect, then, " reality is entirely reconceivable.... Our experience of the accidents of objects has no more direct claim to being veridical than our judgments about the nature of things." 3 Even a partial list of the factors contributing to the genesis of the notion of radical incommensurability would be impressive : the rise of historical consciousness and its assertion of the historically conditioned nature of all world views, the emphasis in the sociology of knowledge on the socially constructed nature of all visions of reality, the contention in the philosophy of science that.all scientific observation and appraisal is ineluctably theory-laden, a:s well as the Marxist critique of theoretical positions as intellectual supports for vested class interests. Without gainsaying the significance of these and other possible factors in the evolution of the notion of incommensurability, we would argue that a proper gra:sp of its apparent plausi2 Against Method: Outline of an Anarchistic Theory of Knowledge (London : NLB, 1975), p. 274. a Victor Preller, Di·vine Science And The Science Of God (Princeton: Princeton University Press, 1967), p. 69. GROUNDING THE HUMAN CONVERSATION ~87 bility and consequent appeal can best be attained if we unearth its foundation in ·a relativist reading of Kant's Copernican Revolution in philosophy. Kant's connection with this notion turns on a particular development of his basic distinction between " our " mode of conceiving reality and reality-initself (Ding-an-Sich). In Kant's view, we can only know the appearance of reality as filtered through our conceptual scheme; thus, the thing-in-itself-reality in its pure nature or aseity-is opaque and impenetrable. For Kant, however, there was only one conceptual scheme: namely, the scheme structured by the presuppositions of Euclidean geometry and Newtonian physics. Kant believed that one of his great contributions to our theoretical life was to demonstrate that this scheme was coterminous with the powers of human conceptualization as such... (shrink)

Near the beginning of the Nicomachean Ethics, Aristotle claims that “our discussion will be adequate if its degree of clarity reflects the subject matter.” Those who seek to give a proper “theoretical” account of some enterprise, but who neglect this wise Aristotelian counsel, do so at their own peril. Aristotle is urging that sound theory should reflect and elucidate actual practice. When philosophical speculation loses touch with such practice, it tends to caricature what it ought to clarify. For example, Steven (...) Weinberg points out the disparity that often exists between the view of science one finds expounded by some contemporary “philosophers of science” and that presupposed by those really engaged in scientific research: “From time to time I have tried to read current work on the philosophy of science.

"Joseph Marechal, who became one of the most important figures in the twentieth-century revival of the thought of St. Thomas Aquinas, set for himself an ambitious intellectual project. His goal was to demonstrate that the realist theory of knowledge first enunciated by Aristotle in the ancient world and developed by Aquinas in the thirteenth century is the key to a coherent philosophy of man and being. According to Marechal, once late medieval philosophy moved away from Aquinas's epistemological foundations, no longer (...) could it construct a satisfactory unity of knowledge, man, and being. Thus modern Western philosophers, specifically Descartes, began their quest to elaborate an adequate intellectual account of human experience on the basis of a flawed philosophical legacy."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.
