The Idea of History is the best-known book of the great Oxford philosopher, historian, and archaeologist R.G. Collingwood. It was originally published posthumously in 1946, having been mainly reconstructed from Collingwood's manuscripts, many of which are now lost. For this revised edition, Collingwood's most important lectures on the philosophy of history are published here for the first time. These texts have been prepared by Jan van der Dussen from manuscripts that have only recently become available. The lectures contain Collingwood's first (...) comprehensive statement of his philosophy of history; they are therefore essential for a full understanding of his thought, and in particular for a correct interpretation of The Idea of History itself. Van der Dussen contributes a substantial introduction in which he explains the background to this new edition and surveys the scholarship of the last fifty years. (shrink)

This book explains and defends a central ideas in the theory of history put forward by R. G. Collingwood, perhaps the foremost philosopher of history in the 20th century. Professor Dray analyses critically the idea of re-enactment, explores the limits of its applicability, and determines its relationship to other key Collingwoodian ideas, such as the role of imagination in historical thinking, and the indispensability of a point of view.

Scientists and laypeople alike use the sense of understanding that an explanation conveys as a cue to good or correct explanation. Although the occurrence of this sense or feeling of understanding is neither necessary nor sufficient for good explanation, it does drive judgments of the plausibility and, ultimately, the acceptability, of an explanation. This paper presents evidence that the sense of understanding is in part the routine consequence of two well-documented biases in cognitive psychology: overconfidence and hindsight. In light of (...) the prevalence of counterfeit understanding in the history of science, I argue that many forms of cognitive achievement do not involve a sense of understanding, and that only the truth or accuracy of an explanation make the sense of understanding a valid cue to genuine understanding.

Develops a logical analysis of dialogue in which two or more parties attempt to advance their own interests. It includes a classification of the major types of dialogues and a discussion of several important informal fallacies.

Part of logic consists in uncovering ways in which logical processes of great universality and utility are over-extended, e.g., in the misguided search for the cause of everything. It is suggested here that the search for missing premises defined as premises that make a deduction out of every argument has its own limits of sense. While often useful, it is sometimes just wrongly used by requiring that the reconstructed argument have the same categorical conclusion as the original one; and sometimes (...) inappropriately used when the argument itself does not rest upon assumptions different from itself.

In this much-anticipated revision and translation of Scienza e Retorica, Marcello Pera argues that rhetoric is central to the making of scientific knowledge. Pera begins with an attack of what he calls the "Cartesian syndrome"--the fixation on method common to both defenders of traditional philosophy of science and its detractors. He argues that in assuming the primacy of methodological rules, both sides get it wrong. Scientific knowledge is neither the simple mirror of nature nor a cultural construct imposed by contingent (...) interests, thus we must replace the idea of the scientific method with that of scientific rhetoric. Pera proposes a new dialectics of science to overcome the tension between normative and descriptive philosophies of science by focusing on the rhetoric in the proposition, defense, and argumentation of theories. Examining the uses of rhetoric in debates drawn from Galileo’s Dialogues, Darwin’s Origins, and the Big Bang-Steady State controversy in cosmology, Pera shows how the conduct of science involves not just nature and the inquiring mind, but nature, the inquiring mind, and a questioning community which, through the process of attack, defense, and dispute, determines what is science. Rhetoric, then, is an essential element in the constitution of science as the practice of persuasive argumentation through which results gain acceptance. (shrink)

This paper describes an approach to legal logic based on the formal analysis of argumentation schemes. Argumentation schemes a notion borrowed from the .eld of argumentation theory - are a kind of generalized rules of inference, in the sense that they express that given certain premises a particular conclusion can be drawn. However, argumentation schemes need not concern strict, abstract, necessarily valid patterns of reasoning, but can be defeasible, concrete and contingently valid, i.e., valid in certain contexts or under certain (...) circumstances. A method is presented to analyze argumentation schemes and it is shown how argumentation schemes can be embedded in a formal model of dialectical argumentation. (shrink)

Explanation-Aware Computing: Papers from the 2007 AAAI Workshop, Association for the Advancement of Artificial Intelligence, Technical Report WS-07-06, Menlo Park California, AAAI Press, 2007, 1-9.

In this paper we consider persuasion in the context of practical reasoning, and discuss the problems associated with construing reasoning about actions in a manner similar to reasoning about beliefs. We propose a perspective on practical reasoning as presumptive justification of a course of action, along with critical questions of this justification, building on the account of Walton. From this perspective, we articulate an interaction protocol, which we call PARMA, for dialogues over proposed actions based on this theory. We outline (...) an axiomatic semantics for the PARMA Protocol, and discuss two implementations which use this protocol to mediate a discussion between humans. We then show how our proposal can be made computational within the framework of agents based on the Belief-Desire-Intention model, and illustrate this proposal with an example debate within a multi agent system.

All volumes of Professor Guthrie's great history of Greek philosophy have won their due acclaim. The most striking merits of Guthrie's work are his mastery of a tremendous range of ancient literature and modern scholarship, his fairness and balance of judgement and the lucidity and precision of his English prose. He has achieved clarity and comprehensiveness.

In this paper we describe an approach to practical reasoning, reasoning about what it is best for a particular agent to do in a given situation, based on presumptive justifications of action through the instantiation of an argument scheme, which is then subject to examination through a series of critical questions. We identify three particular aspects of practical reasoning which distinguish it from theoretical reasoning. We next provide an argument scheme and an associated set of critical questions which is able (...) to capture these features. In order that both the argument scheme and the critical questions can be given precise interpretations we use the semantic structure of an Action-Based Alternating Transition System as the basis for their definition. We then work through a detailed example to show how this approach to practical reasoning can be applied to a problem solving situation, and briefly describe some other previous applications of the general approach. In a second example we relate our account to the social laws paradigm for co-ordinating multi-agent systems. The contribution of the paper is to provide firm foundations for an approach to practical reasoning based on presumptive argument in terms of a well-known model for representing the effects of actions of a group of agents.

Psychology and philosophy have long studied the nature and role of explanation. More recently, artificial intelligence research has developed promising theories of how explanation facilitates learning and generalization. By using explanations to guide learning, explanation-based methods allow reliable learning of new concepts in complex situations. -/- This volume addresses fundamental issues in generating and judging explanations: When to explain, what constitutes an explanation, how to build explanations, and how to evaluate candidate explanations. It argues that standard models, which are neutral (...) to context and experience, are inadequate to deal with the problems that arise in everyday explanation. It presents an alternative theory in which context---involving explainer beliefs, goals and experience---is crucial in generating and judging explanations. It examines the role of anomalies in motivating explanation, describes a model of pattern-based anomaly detection, and shows how an analysis of the content of anomalies, explanations, and explanation purposes can be used to guide generation and evaluation of explanations by a case-based explanation system. The theory is implemented in ACCEPTER, a computer system that understands stories, detects anomalous events, guides retrieval and adaptation of stored explanations, and evaluates candidate explanations.
