Because physical theories typically predict numerical values, an improvement in experimental precision reduces the tolerance range and hence increases corroborability. In most psychological research, improved power of a statistical design leads to a prior probability approaching 1/2 of finding a significant difference in the theoretically predicted direction. Hence the corroboration yielded by "success" is very weak, and becomes weaker with increased precision. "Statistical significance" plays a logical role in psychology precisely the reverse of its role in physics. This problem is (...) worsened by certain unhealthy tendencies prevalent among psychologists, such as a premium placed on experimental "cuteness" and a free reliance upon ad hoc explanations to avoid refutation.

Criticism of Larry Laudan's views on disagreement and progress in science.

Written in the 1960s, TRUTH AND METHOD is Gadamer's magnum opus.

Feyerabrend argues that intellectual progress relies on the creativity of the scientist, against the authority of science.

Finally, our argument suggests that the relationship and the distinction between literature and philosophy cannot be made in terms of a distinction between aesthetic and epistemological categories. All philosophy is condemned, to the extent that it is dependent upon figuration, to be literary and, as the depository of this very problem, all literature is to some extent philosophical. The apparent symmetry of these statements is not as reassuring as it sounds since what seems to bring literature and philosophy together is, (...) as in Condillac's argument about mind and object, a shared lack of identity or specificity. Contrary to common belief, literature is not the place where the unstable epistemology of metaphor is suspended by aesthetic pleasure, although this attempt is a constitutive moment of its system. It is rather the place where the possible convergence of rigor and pleasure is shown to be a delusion. The consequences of this lead to the difficult question whether the entire semantic, semiological, and performative field of language can be said to be covered by tropological models, a question which can only be raised after the proliferating and disruptive power of figural language has been fully recognized. Paul de Man, Tripp Professor in the humanities and chairman of the comparative literature department of Yale University, is the author of Blindness and Insight: Essays in the Rhetoric of Contemporary Criticism. His previous contribution to Critical Inquiry, "Political Allegory in Rousseau," appeared in the Summer 1976 issue and appears in his book Allegories in Reading. (shrink)

An 'Essay on man' is an original synthesis of contemporary knowledge, a unique interpretation of the intellectual crisis of our time, and a brilliant vindication of manís ability to resolve human problems by the courageous use of his mind.

First published in 1949 expressly to introduce logical positivism to English speakers. Reichenbach, with Rudolph Carnap, founded logical positivism, a form of epistemofogy that privileged scientific over metaphysical truths.

What psychological and philosophical significance should we attach to recent efforts at computer simulations of human cognitive capacities? In answering this question, I find it useful to distinguish what I will call "strong" AI from "weak" or "cautious" AI. According to weak AI, the principal value of the computer in the study of the mind is that it gives us a very powerful tool. For example, it enables us to formulate and test hypotheses in a more rigorous and precise fashion. (...) But according to strong AI, the computer is not merely a tool in the study of the mind; rather, the appropriately programmed computer really is a mind, in the sense that computers given the right programs can be literally said to.

Originally published in 1930, this well-known text by the late British philosopher Abraham Wolf offers the student a practical, consistent, and comprehensive approach to logic which remains unique in its field. Dr. Wolf here deals systematically with the two main types of reasoning - formal logic and inductive logic - and their various applications. All the main elements of logic - such as inference, syllogism, dilemmas, evidence, deductive and inductive methods, and probability - are subsumed under these general headings. Professor (...) Wolf strongly emphasizes the fact that logic cannot be mastered without some practical application; at the end of this volume, therefore, he includes a section of exercises based on each chapter. His unusally interesting appendix examines such matters as symbolic as logic, fallacies, the law of contradiction, modal propositions, the existential import of categorical propositions, predictables, and categories.

_Conjectures and Refutations_ is one of Karl Popper's most wide-ranging and popular works, notable not only for its acute insight into the way scientific knowledge grows, but also for applying those insights to politics and to history. It provides one of the clearest and most accessible statements of the fundamental idea that guided his work: not only our knowledge, but our aims and our standards, grow through an unending process of trial and error.

Originally published in 1969. This book explains what is wrong with the traditional methodology of "inductive" reasoning and shows that the alternative scheme of reasoning associated with Whewell, Pierce and Popper can give the scientist a useful insight into the way he thinks.
