A theory of analogy must describe how the meaning of an analogy is derived from the meanings of its parts. In the structure‐mapping theory, the interpretation rules are characterized as implicit rules for mapping knowledge about a base domain into a target domain. Two important features of the theory are (a) the rules depend only on syntactic properties of the knowledge representation, and not on the specific content of the domains; and (b) the theoretical framework allows analogies to be distinguished (...) cleanly from literal similarity statements, applications of abstractions, and other kinds of comparisons.Two mapping principles are described: (a) Relations between objects, rather than attributes of objects, are mapped from base to target; and (b) The particular relations mapped are determined by systematicity, as defined by the existence of higher‐order relations.

This target article presents a new computational theory of explanatory coherence that applies to the acceptance and rejection of scientific hypotheses as well as to reasoning in everyday life, The theory consists of seven principles that establish relations of local coherence between a hypothesis and other propositions. A hypothesis coheres with propositions that it explains, or that explain it, or that participate with it in explaining other propositions, or that offer analogous explanations. Propositions are incoherent with each other if they (...) are contradictory, Propositions that describe the results of observation have a degree of acceptability on their own. An explanatory hypothesis is acccpted if it coheres better overall than its competitors. The power of the seven principles is shown by their implementation in a connectionist program called ECHO, which treats hypothesis evaluation as a constraint satisfaction problem. Inputs about the explanatory relations are used to create a network of units representing propositions, while coherende and incoherence relations are encoded by excitatory and inbihitory links. ECHO provides an algorithm for smoothly integrating theory evaluation based on considerations of explanatory breadth, simplicity, and analogy. It has been applied to such important scientific cases as Lovoisier's argument for oxygen against the phlogiston theory and Darwin's argument for evolution against creationism, and also to cases of legal reasoning. The theory of explanatory coherence has implications for artificial intelligence, psychology, and philosophy. (shrink)

The now-classic Metaphors We Live By changed our understanding of metaphor and its role in language and the mind. Metaphor, the authors explain, is a fundamental mechanism of mind, one that allows us to use what we know about our physical and social experience to provide understanding of countless other subjects. Because such metaphors structure our most basic understandings of our experience, they are "metaphors we live by"--metaphors that can shape our perceptions and actions without our ever noticing them. In (...) this updated edition of Lakoff and Johnson's influential book, the authors supply an afterword surveying how their theory of metaphor has developed within the cognitive sciences to become central to the contemporary understanding of how we think and how we express our thoughts in language.

This paper provides a computational characterization of coherence that applies to a wide range of philosophical problems and psychological phenomena. Maximizing coherence is a matter of maximizing satisfaction of a set of positive and negative constraints. After comparing five algorithms for maximizing coherence, we show how our characterization of coherence overcomes traditional philosophical objections about circularity and truth.

RésuméCet article examine diverses façons d'exploiter l'éthique aristotélicienne pour rendre compte philosophiquement de l'hypocrisie. Aristote lui-même n'apas dit grand chose d'explicite à ce sujet, mais nous nous employons à identifier et à scruter les passages qui sont les plus pertinents pour un traitement distinctif de l'hypocrisie, élucidant en cours de route un certain nombre de confusions à propos d'Aristote. Nous envisageons divers domaines d'émotion et d'action qui pourraient fournir un lieu propre au vice de l'hypocrisie, ceux en particulier de l'engagement (...) personnel, du souci à l'égard des opinions d'autrui, et de la sincérité. Nous concluons de cet examen que la doctrine du juste milieu ne fournit pas une explication satisfaisante de l'hypocrisie. Nous proposons alors que si un système moral comme celui d' Aristote doit rendre compte de la moralité dans son entièreté, il lui faut trouver place pour des phénomènes qui excèdent les limites de la doctrine du juste milieu. L'hypocrisie, selon nous, appartient précisément à cette famille de phénomènes. Finalement, nous esquissons une approche de l'hypocrisie qui fait usage d'éléments aristotéliciens, mais sans pour autant s'y confiner. (shrink)

This book is parapsychological study of the meaningful coincidence of events, extrasensory perception, and similar phenomena.

This book, which can be read independently, deals with more specifically linguistic problems in semantics and contains substantial original material.
