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.

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.

Essential to Peirce's distinction among three kinds of reasoning, deduction, induction and abduction, is the claim that each is correlated to a unique species of validity irreducible to that of the others. In particular, abductive validity cannot be analyzed in either deductive or inductive terms, a consequence of considerable importance for the logical and epistemological scrutiny of scientific methods. But when the full structure of abductive argumentation — as viewed by the mature Peirce — is clarified, every inferential step in the process can be seen to dissolve into familiar forms of deductive and inductive reasoning. Specifically, the final stage is a special type of practical inference which, if correct, is deductively valid, while the creative phase, surprisingly, is not inferential at all. In neither is abduction a type of inference to the best explanation. The result is a major reassessment of the relevance of Peirce's views to contemporary methodological studies.

Two claims have been prominent in recent discussion of self-consciousness. One is that first-person reference or first-person thinking is irreducible {Irreducibility Thesis), and the other is that awareness of self accompanies at least all those conscious states through which one refers to something. The latter {Ubiquity Thesis) has long been associated with philosophers like Fichte, Brentano and Sartre, but recently variants have been defended by D. Henrich and M. Frank. Facing criticism from three arguments which nevertheless cannot decisively refute the Self-Ascription theory it turns out that Frank is correct to seek the grounds for the Ubiquity Thesis in indexical thinking and that his insights can be exploited in an alternative argument for the Ubiquity Thesis

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

In ‘Omniprescient Agency’ David P. Hunt challenges an argument against the possibility of an omniscient agent. The argument – my own in ‘Agency and Omniscience’ – assumes that an agent is a being capable of intentional action, where, minimally, an action is intentional only if it is caused, in part, by the agent's intending. The latter, I claimed, is governed by a psychological principle of ‘least effort’, namely, that no one intends without antecedently feeling that deliberate effort is needed to achieve desired goals, such effort has a chance of success, and it is yet contingent whether the effort will be expended and the goals realized. The goals can be anything from immediate intentional doings, tryings or basic actions, to remote and perhaps unlikely consequences of actions, e.g. global justice. The thrust of the principle is that it would be impossible for a wholly rational self-aware agent to intend without a background presumption of an open future as concerns the desired state and the means to it. But this presumption embodies a sense of contingency which, in turn, requires an acknowledged ignorance about what the future holds, otherwise the future would appear closed relative to present knowledge with the desired state presented as either guaranteed or ruled out . Regardless whether this self-directed attitude is accurate, it follows that intentional action precludes complete knowledge of one's present and future. Consequently, no omniscient or omniprescient being can be an agent

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..

The role of reason, and its embodiment in philosophical-scientific theorizing, is always a troubling one for religious traditions. The deep emotional needs that religion strives to satisfy seem ever linked to an attitudes of acceptance, belief, or trust, yet, in its theoretical employment, reason functions as a critic as much as it does a creator, and in the special fields of metaphysics and epistemology its critical arrows are sometimes aimed at long-standing cherished beliefs. Understandably, the mere approach to these beliefs through organized philosophical activity, however well-intended, is viewed with suspicion by ecclesiastical authorities and the devout. The attitude towards philosophical inquiry on the part of the Islamic religious community might be thought to typify this reaction. As one of the great prophetic religions, the self-avowed image of Islam is of a tradition which already possesses the truth as set forth in the divine revelation of the Qur'an. What need is there for philosophizing on fundamental matters, e.g., the ultimate nature of reality, the foundations of morality, the modes whereby the divine is connected with the temporal? The structure of creation is already made clear, the "straight path" for living already manifest. how can philosophical activity be anything but a source of divisive controversy, for as it turns its gaze to the foundations upon which the Shari`a' (Islamic Law) rests, or to the grounds for religious belief itself, it cannot avoid turning up alternative viewpoints, different perspectives on divine revelation, noting various weaknesses in received 1 interpretations? In short, isn't the practice of philosophy a threat to Islam's promise of providing a comprehensive way of living devoid of skepticism and uncertainty about the place of a human in God's creation and his or her role in the 'umma (Islamic community)? This problem is not unique to Islam, nor is it a new one within Islam. We know that it has been debated by Islamic thinkers since the translations of the Greek philosophers began to appear in an organized Islamic world during the 8th Century A..

François Recanati describes a metarepresentation as a representation of linguistic and mental representations. Two levels of content are involved, that of a metarepresentation dS, and that of the object representation S. According to Recanati’s “iconicity thesis,” dS contains S semantically as well as syntactically, so that one cannot entertain dS without also entertaining S. Iconicity “suggests” the doctrine of semantic innocence, whereby an embedded object-representation has the same content it would have when uttered in isolation—its “normal” semantic value—and one of Recanati’s principal aims is to show how the opacity of oratio obliqua and oratio recta constructions can be explained without sacrificing innocence. His treatment is set firmly within the framework of Kaplan 1989 and is inspired by the account of quotation in Davidson 1968. Though devoid of technical and metaphysical encumbrance, his book is not a lean display of a single vision, since Recanati spends considerable time on proposals that he ends up rejecting or modifying. Some readers might become impatient with the detailed comparisons, but the dedicated student will welcome the learned discussion of alternatives. In all, Recanati has given us an excellent study of metarepresentation, enlivened by state-of-the-art pragmatics and at the forefront of the latest discourse on attitudinal ascriptions.
