In this paper, new evidence is presented for the assumption that the reason-relation reading of indicative conditionals ('if A, then C') reflects a conventional implicature. In four experiments, it is investigated whether relevance effects found for the probability assessment of indicative conditionals (Skovgaard-Olsen, Singmann, and Klauer, 2016a) can be classified as being produced by a) a conversational implicature, b) a (probabilistic) presupposition failure, or c) a conventional implicature. After considering several alternative hypotheses and the accumulating evidence from other studies as (...) well, we conclude that the evidence is most consistent with the Relevance Effect being the outcome of a conventional implicature. This finding indicates that the reason-relation reading is part of the semantic content of indicative conditionals, albeit not part of their primary truth-conditional content. (shrink)
Much of what we believe we know, we know through the testimony of others. While there has been long-standing evidence that people are sensitive to the characteristics of the sources of testimony, for example in the context of persuasion, researchers have only recently begun to explore the wider implications of source reliability considerations for the nature of our beliefs. Likewise, much remains to be established concerning what factors influence source reliability. In this paper, we examine, both theoretically and empirically, the (...) implications of using message content as a cue to source reliability. We present a set of experiments examining the relationship between source information and message content in people's responses to simple communications. The results show that people spontaneously revise their beliefs in the reliability of the source on the basis of the expectedness of a source's claim and, conversely, adjust message impact by perceived reliability; hence source reliability and message content have a bi-directional relationship. The implications are discussed for a variety of psychological, philosophical and political issues such as belief polarization and dual-route models of persuasion. (shrink)
Conditionals and conditional reasoning have been a long-standing focus of research across a number of disciplines, ranging from psychology through linguistics to philosophy. But almost no work has concerned itself with the question of how hearing or reading a conditional changes our beliefs. Given that we acquire much—perhaps most—of what we believe through the testimony of others, the simple matter of acquiring conditionals via others’ assertion of a conditional seems integral to any full understanding of the conditional and conditional reasoning. (...) In this paper we detail a number of basic intuitions about how beliefs might change in response to a conditional being uttered, and show how these are backed by behavioral data. In the remainder of the paper, we then show how these deceptively simple phenomena pose a fundamental challenge to present theoretical accounts of the conditional and conditional reasoning – a challenge which no account presently fully meets.

Reasoning with conditionals is central to everyday life, yet there is long-standing disagreement about the meaning of the conditional. One example is the puzzle of so-called missing-link conditionals such as "if raccoons have no wings, they cannot breathe under water." Their oddity may be taken to show that conditionals require a connection between antecedent ("raccoons have no wings") and consequent ("they cannot breathe under water"), yet most accounts of conditionals attribute the oddity to natural language pragmatics. We present an experimental (...) study disentangling the pragmatic requirement of discourse coherence from a stronger notion of connection: probabilistic relevance. Results indicate that mere discourse coherence is not enough to make conditionals assertable. (shrink)
As argumentation theory has moved away from classical logic as a standard, sources have played an increasingly important role in the psychology of argumentation. Considering the connections between arguments and their sources is important for both descriptive and normative projects. This chapter draws together different strands of research in the psychology of argumentation and their differing views on source characteristics: namely, procedural rules, pragmatics, argumentation schemes and Bayesian Argumentation. We argue for a reconciliation of these different approaches around a probabilistic (...) notion of relevance. (shrink)
Josef Pieper [1904-1997], a popular and prolific German philosopher, is probably best known for his small volume Leisure: The basis of culture . The book in review, Tradition: Concept and claim, was published originally in 1970, but the first English translation came out in 2008. Undoubtedly, Pieper, if he were still alive, would claim that the message of Tradition bears the same kind of importance today as it did in 1970—perhaps of even greater significance today due to the further development (...) of such phenomena as postmodernist philosophy and secularism in Western culture. In ninety-nine pages, the book has a Table of Contents, Translator’s Preface and Introduction, six chapters, Notes, Bibliography, and Index. In this book the author attempts to describe the nature of tradition . The “kind of importance” characterizing tradition, according to the author, is capsulized in the final sentence of the book: “…real unity among human beings has its roots in nothing else but the common possession of tradition in the strict sense—I mean our sharing the sacred tradition that goes back to God’s words”.

Martin Buber’s sustained effort to transcend the world—in the world— can be explained by his interpretation of Hasidism and his philosophy of dialogue. His motivation is derived from personal and cultural circumstances; indigenous to both was what he called the “eclipse of God,” the disappearance of God from the world, which he viewed as the culprit in the disintegration of authentic human values. He learned and taught that human persons encounter God , not by escaping the world, but by “redeeming” (...) the world through I-Thou relationships with others in daily living. Buber’s contemporary significance is addressed in closing. (shrink)
The term "humanism" bears many meanings. The origin of its usage is associated with the Renaissance, but it can also be predicated on the thought of earlier and later generations. The most general purpose of this paper is to suggest the inevitable reliance of an array of meanings of "humanism" upon philosophical categories. To support this thesis, the author attempts to clarify some fundamental differences between the philosophical humanisms of Auguste Comte [1798-1957] and Blaise Pascal [1623-1662]. For purposes of expansion (...) and clarification, Comte is associated with John Dewey [1859-1952] and Pascal with John Henry Newman [1801-1890]. In conclusion, brief attention is given to some contrasting educational implications and to some applications to the recent past. (shrink)
Terry Eagleton. The meaning of life: A very short introductionOxford: University Press, 2007, 109 pp.For a very short introduction to the meaning of life, this 109-page volume provokes much reflection upon many possible meanings of life. The topic of the book is examined from innumerable perspectives. While the author does not seem to hide his personal views, he does not manifest them as directly as the reader might wish. The meaning of life is well-written and witty; it has four chapters, (...) about three pages on “Further reading,” a brief Index and a dozen illustrations. Although only the first chapter is entitled “Questions and answers,” I am wondering whether all four chapters could bear that title appropriately. In any case, the first paragraph of the first page raises the question of meaninglessness: whether the question of the meaning of life is a meaningful question at all; whether it really is capable of carrying a meaningful answer.

The relevance of observations in introducing time dependence into quantum cosmology is discussed, some of the important features being illustrated by a simple example. Although the concept of time arises in a natural way even with a constant wave function, there are some conceptual difficulties in understanding how arguments which are familiar in classical cosmology translate to the quantum case.
The intertwining careers of William Torrey Harris converge in twelve of the Annual Reports of the Board of Directors for St. Louis Public Schools. Harris formulated most of the essential features of these twelve reports as the Superintendent of Schools from 1867 to 1869. These particular reports—which have been acclaimed nationally and internationally—are said to be among the most valuable official publications in American educational literature. They are far different from the descriptive documents originally intended by their author. This study (...) demonstrates that Harris provided an authentic philosophy of education, a set of interrelated philosophical principles and their applications to educational problems. The substance of Harris's philosophy of education is focused upon a broadly based philosophical anthropology in relationship primarily to the purposes, curriculum, and teaching methods in intellectual, moral, and religious education.
