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.

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..

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

Preface The conflict between Israeli Jews and Palestinian Arabs has endured for a century. It centers on control of territory and, as common in such disputes, is characterized by conquest, destruction, and revenge, with all the animosity and sorrow that these actions bring. Because the land in question is terra sancta to three major religions, the conflict evokes powerful passions involving identity, honor, and the propriety of cultural claims. That its disputants employ sophisticated arguments and armaments, that they are willing to combat not only each other but rival voices within their own ranks, and that decades of international diplomacy have failed to produce a satisfactory solution, render it "one of the most difficult political problems of our time, perhaps the most difficult of them all". Marked by a series of surprising achievements, deceptions and atrocities in which each side has underestimated the tenacity and resourcefulness of the other, it guarantees fascinating study

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..

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.

Discussions of free will have frequently centered on principles concerning ability, control, unavoidability and other practical modalities. Some assert the closure of the latter over various propositional operations and relations, for example, that the consequences of what is beyond one's control are themselves beyond one's control.1 This principle has been featured in the unavoidability argument for incompatibilism: if everything we do is determined by factors which are not under our control, then, by the principle, we are unable to act and choose other than we actually did. A second family of principles concerns the fixity of the past and the laws of nature. If no one is able to alter the past or violate the laws it seems but a small step to conclude that no one can do anything such that if they did it then the past would be altered or the laws violated. Accordingly, if an agent's performing an act is necessitated by the past and laws, then the agent is unable to refrain from that act at that time. Generalizing, determinism precludes anyone from doing anything other than what he or she did.2

It is widely agreed that the references of indexical expressions are fixed partly by their relations to contextual parameters such as the author, time, and place of the utterance. Because of this, indexicals are sometimes described as token-reflexive or utterance-reflexive in their semantics. But when we inquire into how indexicals help us to identify items within experience, we find that while utterance-reflexivity is essential to an interpretation of indexical tokens, it is not a factor in a speaker's identificatory use of indexicals. Tokens cannot be interpreted unless they are first produced, and obviously the speaker who produces them does not depend upon utterance parameters in order to identify their referents in the way that hearers do. Consequently, the standard reflexive accounts of indexicals are of little use in explaining the speaker's identificatory use of indexicals, and must be either replaced or complemented by a further theory of the role of indexicals in thought. This paper provides an account of indexical identification that is attentive to a speaker's as well as a hearer's identification and reveals how indexicals are inextricably perspectival.
