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.

Philosophers commonly speak of a person’s being justified in believing a proposition by one or more reasons he or she has for it. This phenomenon, often called inferential or indirect justification, seems so pervasive that some are tempted to count all epistemic justification as such, though even dessenters from this view can acknowledge that justification through reasons is central to wide domains of cognitive appraisal, e.g., in science and in law. A basic task for the epistemologist is to explain how an indirectly justified belief is related to the evidential belief by which it is justified. Here, I will address one aspect of this issue, namely, if S is indirectly justified in believing p by his belief that q must S also be justified in believing that q is a reason for p, or, in other words, that q confirms or supports p? An affirmative response imposes what can be called a requirement of a justified connecting belief or, as I shall speak, of a warranted connecting proposition upon indirect justification. Opinion is divided as to its necessity, with many reliabilists anxious to avoid it altogether. I propose to remove certain obstacles to its acceptance, even within a reliability framework, while attempting a more precise determination of what the requirement comes to.

Indexicals are inevitably autobiographical, even when we are not talking about ourselves. For example, if you hear me say, "That portrait right there is beautiful," you can surmise not only that I ascribe beauty to an object of my immediate awareness but also something about my spatial relation to it. Again, if I praise you directly within earshot of others by using the words, "You did that very well!," my concern need not be to cause them to think the exact thought I have; they might not be in a position to address you as you and I might not care what they think of your performance. My purpose is to get them to ascribe to me an attitude that I express with a second-person indexical, to convince them that I am an encouraging and supportive person inasmuch as I addressed someone with words of praise. Indexicals are autobiographical not only because they issue from a speaker--all utterances do--but because they reveal something about the speaker's orientation toward and encounter with objects in a way that non-indexical language fails to do. For this reason, care must be taken in reporting indexically-expressed thoughts. Suppose the Chair of my Department informs me, (1)I am upset about the Dean's report. I cannot relate what he said by reiterating his words within indirect discourse, viz., (2)The Chair said that I am upset about the Dean's report. Because 'I' expresses speaker's reference, my assertion of (2) would cause a hearer to misconstrue who is said to be upset.i Alternatively, the sentence, (3)The Chair said that the Chair is upset about the Dean's report

John Searle describes our sense of freedom as an experience of a “gap” between an intentional action and its psychological antecedents, specifically, our reasons.. Since the gap is itself understood as a lack of causation, then no agent can accept the antecedent determination of voluntary action except at the price of “practical inconsistency.” I argue that despite Searle’s insightful discussion, the sense of freedom is not an experience of a gap as he describes it but, instead, is a higher-order attitude concerning one’s limited grasp of causes. As a result, a determinist can engage in voluntary action without falling into inconsistency

: Frege’s remarks about the first-person pronoun in Der Gedanke have elicited numerous commentaries, but his insight has not been fully appreciated or developed. Commentators have overlooked Frege’s reasons for claiming that there are two distinct first-person senses, and failed to realize that his remarks easily generalize to all indexicals. I present a perspectival theory of indexicals inspired by Frege’s claim that all indexical types have a dual meaning which, in turn, leads to a duality of senses expressed by indexical tokens. Keywords : Indexicals; First Person; Perspective; Senses La doppia natura degli indessicali: una posizione fregeana Riassunto : Le osservazioni di Frege sul pronome di prima persona contenute in Der Gedanke hanno sollevato numerosi commenti, ma le sue intuizioni non sono state pienamente comprese o sviluppate. I commentatori di Frege hanno trascurato le ragioni per le quali egli sosteneva che ci sono due distinti sensi della prima persona e non hanno colto come queste sue osservazioni possono essere facilmente estese a tutti gli indessicali. Intendo presentare qui una posizione prospettivista sugli indessicali, ispirata dall’affermazione di Frege per cui tutti i tipi di indessicali hanno un doppio significato che, a sua volta, porta a una doppia natura dei sensi espressi dalle occorrenze indessicali. Parole chiave : Indessicali; Prima persona; Prospettiva; Sensi

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

My topic today is Europe’s responsibility for the creation and resolution the Israeli-Palestinian conflict, one of the most bitter and explosive political struggles in the world today. In the past 60 years, it has consumed thousands of lives, billions of dollars, and endless hours of debate. It is not localized; it is at the heart of on-going tensions between the West and the Islamic world, and it is directly related to the current American aggression in southern Asia. The fate of international relations during the 21st century depends on its resolution as, arguably, it is single greatest threat to world peace. The situation is made even more serious by the fact that there are no immediate prospects of a resolution of this conflict, a fact that should cause anyone concerned about justice, peace, and international stability to give serious thought about what ought to be done. This requires an effort to understand the historical roots of the dispute. The neglect of history, an ignorance of past causes of present conflicts, grievances, passions, and trends, is dangerous for any country, especially for a democracy where citizens need reliable information if they are to make wise decisions, and most crucially, for a democracy that is, or aspires to be, a superpower.

According to Hector-Neri Castañeda, indexical reference is our most basic means of identifying the objects and events we experience and think about. Its tokens reveal our own part in the process by denoting what are "referred to as items present in experience" (Castañeda 1981, 285-6). If you hear me say, "Take that box over there and set it next to this box here," you learn something about my orientation towards the referents in a way that is not conveyed by, "Take the red box and set it next to the blue box." My indexical tokens express what they do not only because they issue from a unique spatio-temporal perspective that I happen to occupy, but also because they reflect my encounter with referents that are differently situated in that perspective. From your perspective, my here might be your there, my you your she, and within my own, a this differs from a that and one this diverges from another. Encounter and orientation within a perspective are the essential ingredients in indexical identification without which particular 'this's, 'that's, 'then's, 'here's, and 'beyond's would be denuded of individuating powess.1 There are several consequences of this description. First, indexical reference is ephemeral because perspective is constantly changing, rendering the indexical status of an entity relative to a given perspective temporary: 1 A this quickly turns into a that, and soon enough it is lost to experience and is not even a remote that; a you goes away and is replaced by another . . . Nothing is really an enduring you -- except God perhaps for the abiding mystic. (Castañeda 1989a, 69) Second, indexical reference is irreducible since non-indexical mechanisms of reference fail to express the subject's involvement or encounter with the referents that indexicals convey. Nor can the various indexicals be reduced to each other.2 Third, because each perspective is unique, indexical reference is essentially subjective..
