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.

: 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

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

Terrorism, as a form of politically motivated violence, is as ancient as organized warfare itself, emerging as soon as one society, pitted against another in the quest for land, resources, or domination, was moved by a desire for vengeance or found advantages in military operations against noncombatants or other ‘soft’ targets. It is sanctioned and glorified in holy scriptures and has been part of the genesis of states and the expansion of empires from the inception of recorded history. The United States itself emerged through the systematic ethnic cleansing of native Americans, a nearly 300-year campaign that featured the destruction of homes and crops, the theft of land, forced expulsions, massacres, and tears.1 While terrorist violence has been employed by both sides in the conflict over Palestine for over 80 years, the prevalence of the rhetoric of ‘terror’ to describe Arab violence against Israeli and Western targets is a more recent phenomenon. For more than three decades, this rhetoric has fostered the popular perception that Arab terrorism is the central problem in the Middle East crisis, and that once solved, progress can be made on other issues. Nothing could be more illusory. The Western obsession with Arab terrorism not only overlooks the fact that terrorist activity between Arabs and Jews has been reciprocal, but, more generally, that attempts to remove an effect without touching its causes are utterly futile. Terrorism between Palestinian Arabs and Israeli Jews is the product of deep divisions, entrenched strategies, and fundamental grievances and will not disappear so long as both sides cling to their present political ambitions and convictions. No informed discussion of its normative status can ignore its historical and political context. At..

By deliberation we understand practical reasoning with an end in view of choosing some course of action. Integral to it is the agent's sense of alternative possibilities, that is, of two or more courses of action he presumes are open for him to undertake or not. Such acts may not actually be open in the sense that the deliberator would do them were he to so intend, but it is evident that he assumes each to be so. One deliberates only by taking it for granted that both performing and refraining from any of the acts under consideration are possible for one, and that which is to be selected is something entirely up to oneself. What is it for a course of action to be presumed as open, or for several courses of action to present themselves as a range of open alternatives? Answering these questions is essential for an understanding of deliberation and choice and, indeed, for the entire issue of free will and responsibility. According to one common view, a deliberator takes the considered options to be open only by assuming he is free to undertake any of them and, consequently, that whichever he does undertake is, as yet, a wholly undetermined matter. Built into the structure of deliberation, on this theory, is an indeterministic bias relative to which any deliberator with deterministic beliefs is either inconsistent or condemned to a fatalistic limbo. An unmistakable challenge is thereby posed: is there an alternative conception of the presuppositions underlying deliberation more congenial to a deterministic perspective yet adequate to the data? Convinced that there is, I develop a partial account of deliberation that, though highly similar to the aforementioned view, diverges at a critical juncture

A familiar means of enhancing the descriptive power of attitudinal reports is the distinction between de re and de dicto readings of ascriptions or, alternatively, between internal and external occurrences of terms and phrases used in ascribing attitudes.i While there is little agreement about the philosophical significance or viability of these contrasts, supporters of cognitive theories of content -- those which take the that-clause of an ascription to express something to which the subject bears a psychological relation, viz., what he or she believes, doubts, wishes for, etc. -- invoke the de re mode whenever the ascriber does not claim to represent the subject's exact content, though, for descriptive or explanatory purposes, finds a partial specification appropriate.ii The strategy is particularly useful for understanding ascriptions containing indexicals. For example, if I overhear Andrea praising my insights, strategies, and calculations, I might report her thoughts as follows: (1) Andrea thinks that I am clever. This ascription is misleading if taken to convey Andrea's exact content; the occurrence of 'I' expresses my thought of myself, not hers. Since she does not think of me in a first-person way, (1) cannot be understood as reporting her disposition to assent to the sentence 'I am clever,' nor to affirm the proposition that I am clever, regardless if the I in question is herself or myself. On certain views of indexical content, I might be unable to specify exactly the proposition she does accept, but I can at least allude to what she has in mind by exporting the pronoun as in, (2) I am someone whom Andrea believes to be clever. or, to retain an overt that-clause, (3) There is someone x who is identical to me and Andrea believes..

To experience is to undergo a process, to be in a state of receiving input which affords information about our environment. For highly developed beings like ourselves, the inputs determining states of conscious sensory perception are among the most important for our survival. At first glance, these states seem relational, each being a situation wherein a percipient X is passively conscious of something Y--its object, subject-matter, or content--without any apparent effort. Of course, the briefest reflection convinces us that despite a seemingly passive reception of data from without, a good deal of interpretation goes into the making of perceptual judgments, as evidenced by their wide variance in the face of like sensory stimulation. One person looking at the slope of a mountain notices a patch of whitish stones; another sees a flock of sheep grazing. They are distinguished by their different reactions to similar input, whether or not these are best construed as inferences, interpretations, or, simply, differing degrees of attentiveness

In recent years, compatibilism has been the target of two powerful challenges. According to the consequence argument, if everything we do and think is a consequence of factors beyond our control (past events and the laws of nature), and the consequences of what is beyond our control are themselves beyond our control, then no one has control over what they do or think and no one is responsible for anything. Hence, determinism rules out responsibility. A different challenge--here called the manipulation argument--is that by allowing agents to be fully determined compatibilist accounts of practical freedom and responsibility are unable to preclude those who are subject to global manipulation from being free and responsible
