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.

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

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

Terrorism is politically motivated violence directed against noncombatants. It is no doubt as ancient as organized warfare itself, emerging as soon as one society, pitted against another in the quest for land, resources, and dominance, was moved by a desire for vengeance, or, found advantages in operations against ‘soft’ targets. While terrorist violence has been present in the conflict between Jews and Arabs over Palestine for over eighty years, the prevalence of the rhetoric of ‘terror’ to describe Arab violence against Israeli and Western targets, is a more recent phenomenon. 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 has been reciprocal, but, more generally, that attempts to remove an effect without touching its causes are utterly futile. Terrorism between Arabs and Israelis is the product of deep divisions, entrenched strategies, and fundamental grievances, and it will not disappear so long as both sides cling to their present political ambitions and convictions. No informed discussion can ignore its historical and political context. At the same time, terrorism is the most noticeable and tragic aspect of a bitter struggle, and any serious attempt to grasp the goals, methods, and passions of either party must realize that it has been central in giving the conflict the shape it has.

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.

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

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..
