According to C. S. Peirce, abduction is a rational attempt to locate an explanation for a puzzling phenomenon, where this is a process that includes both generating explanatory hypotheses and selecting certain hypotheses for further scrutiny. Since inference is a controlled process that can be subjected to normative standards, essential to his view of abductive rasoning is that it is correlated to a unique species of correctness that cannot be reduced to deductive validity or inductive strength. This irreducibility claim is of considerable importance for the logical and epistemological scrutiny of scientific methods, but it is not clear that Peirce produced a convicing argument for it. To the contrary, when the full structure of abductive argumentation is clarified, especially as presented in Peirce’s later writings on the topic, a good case can be made for viewing every inferential step in the abductive process as dissolving into familiar forms of deductive and inductive reasoning. Specifically, hypothesis-selection is a special type of practical inference that, if correct, is deductively valid, while the creative phase, hypothesis-generation, is not inferential at all. Once this is understood, it emerges that the familiar descriptions of abduction as “inference to the best explanation” or as a process of “belief revision” are, at best, misleading.

As practical beings, we act with a sense of freedom, or, to use Kant’s memorable phrase, “unter der Idee der Freiheit.” This attitude is present whenever we are deciding what to do, and it is most clearly revealed when we reflect on what we take for granted while deliberating. Consider a young man, Imad, who lives under an oppressive military occupation and deliberates about whether to join the resistance, leave the country, or continue quietly in his studies hoping that the occupation will be eliminated through the efforts of others. Taking any of these alternatives is likely to have momentous consequences upon his physical safety, his self-esteem, and realization of his goals. Yet, he can no longer tolerate his indecision and feels that he must commit himself somehow. One thing is apparent; Imad faces alternative courses of action, each of which he regards as open for him to undertake at the time. Were he to come to believe of any of the alternatives that it is no longer a genuine option, he would cease deliberating about whether to take it. An agent’s “sense” or “awareness” of personal freedom is nothing more than a presumption of open alternatives made explicit in reflection. But what exactly is its content? What does one accept in presuming a course of action to be “open”? To fix..

Philip E. Devine has presented insightful proposals for defining religion in his essay “On the Definition of Religion” (Faith and Philosophy, July 1986). But despite his illuminating discussion, particularly the treatment of borderline cases, his account fails to distinguish religion as a process or goal-oriented activity from religion as a body of doctrine, and is mistaken (or perhaps unclear) in its proposal that religion per se is committed to the existence of superhuman agents. These deficiencies are exposed herein, and a sketch of an alternative view of religion, inspired by the views of both William James and Josiah Royce, is set forth.

It is said that faith in a divine agent is partly an attitude of trust; believers typically find assurance in the conception of a divine being's will, and cherish confidence in its capacity to implement its intentions and plans. Yet, there would be little point in trusting in the will of any being without assuming its ability to both act and know, and perhaps it is only by assuming divine omniscience that one can retain the confidence in the efficacy and direction of divine agency that has long been the lure of certain religious traditions

The use of single letters in displaying patterns, functions, generalizations, and unknowns, dominates mathematical expression, and for that reason, appears in every domain of theoretical and technical discourse employing even the slightest bit of mathematical language. These variables, as they have come to be called, are the very mark of abstract power and precision, ingenious tools for expressing functionality and valid formulae and, thereby, for providing solutions to types of problems as well as facilitating the calculation of unknowns. Compare, for example, the ease with which we grasp and work with the formula.

In 'You and She*' (ANALYSIS 51.3, June 1991) C.J.F. Williams notes the importance of reflexive pronouns in attributions of propositional attitudes, and claims to improve upon an earlier account of Hector-Neri Castaneda's in [1]. However, to the extent which his remarks are accurate, they reveal nothing that Castaneda hasn't already said, while insofar as they are new, they obliterate distinctions vital to Castaneda's theory. Castaneda called these pronouns quasi-indicators and noted that they function as linguistic devices used for attributing indexical reference to others. For example, in hearing Arthur say 'I am wise' we would report his claim in English with, (1) Arthur thinks that he himself is wise. where 'he himself' is a quasi-indicator used to attribute to Arthur reference to himself qua self -- an expression that Castaneda abbreviated with 'he*.' Note that (1) is quite different from, (2) Arthur thinks that I am wise for 'I', functioning here as an indexical term, represents only the speaker's reference. Nor can (1) be identified with, (3) Arthur thinks that Arthur is wise. for this fails to represent the indexical character of Arthur's thought. Thus, (3) falls short of the informational content of (1). Moreover, as Williams, echoing Castaneda, points out, Arthur might not know that he himself is Arthur, or that he is named 'Arthur.' Hence, (3) might be false even if (1) is true. Williams observes that 'she' can also be used in oratio obliqua to report an indexical 1 usage, e.g., in (4) Arthur told Mary that she ought to talk to Shirley Makepeace's..

Any intelligent discussion of terrorism must demarcate its subject matter, for the term ‘terrorism’ is differently understood and where there is no accord on its meaning there is little chance for agreement on its application or normative status. The best course is to sketch a morally neutral definition that classifies as ‘terrorist’ as many widely-agreed upon cases as possible. Definitions that explicitly render terrorism illegitimate make classification contentious, and it is more informative to base moral assessment on an examination of the case rather than through apriori stipulation. Most writers on the topic agree that terrorism is (i) a deliberate use or threat of violence, (ii) politically-motivated, and (iii) directed against non-military personnel, that is, against civilians or noncombatants. Taking these as the only essential features of terrorism, the simplest and more accurate reportive definition is this: Terrorism is deliberate, politically-motivated violence, or the threat of such, directed against civilians.1 By contrast, Ted Honderich describes terrorism as small-scale violence, driven by a political aim, that violates national or international law and is prima facie morally wrong. He thereby counts a good deal of resistance activity and guerilla warfare as terrorist, even when directed against military personnel, while excluding the large-scale military actions of governments. Of course, he may define the word as he chooses, but given its common..
