John L. Pollock – författare

This book deals with the subject of probabilistic reasoning. Professor Pollock attempts to make general philosophical sense of objective probabilities and he explores their relationship to the problem of induction. He argues that probability is fundamental not only to physical science, but to induction, epistemology, the philosophy of science and to much reasoning of interest to artificial intelligence. He attempts to show how his understanding of probability throws light on these related issues.Pollock's main claim is that the fundamental notion of probability is nomic - that is, it involves the notion of natural law, valid across possible worlds. The various epistemic and statistical conceptions of probability, he demonstrates, are derived from this nomic notion. He goes on to provide a theory of statistical induction; an account of computational principles allowing some probabilities to be derived from others; an account of acceptance rules; and a theory of direct inference.

This book aims to construct a theory of rational decision making for real, resource-bounded, agents. Such decision making must be based on objective probabilities rather than subjective probabilities, and cannot be done by choosing single actions with maximal expected values. Actions must be chosen as parts of plans, and plans must be evaluated in the context of other plans.

John Pollock aims to construct a theory of rational decision making for real agents--not ideal agents. Real agents have limited cognitive powers, but traditional theories of rationality have applied only to idealized agents that lack such constraints. Pollock argues that theories of ideal rationality are largely irrelevant to the decision making of real agents. Thinking about Acting aims to provide a theory of "real rationality."

Although philosophical semantics has become both a discipline in its own right and the source of the analytic techniques used in the rest of philosophy, its foundations have themselves been problematic. To provide a unified account of the field, John L. Pollock discusses issues including the nature of possible worlds, modalities, counterfactuals, and causation. Originally published in 1985. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press.

The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Most philosophical theories of language have assumed that statements (products of assertion) and propositions (objects of belief) are the same things. John L. Pollock denies this, maintaining that even when the speaker is perfectly sincere, what he is thinking need not be the same thing as what he is saying. Originally published in 1982.

One of the most firmly entrenched beliefs of contemporary philosophy is that the only way to analyze a concept is to state its truth conditions. In epistemology this has led to the search for reductive analyses, to phenomenalism, behaviorism, and their analogues in other areas of knowledge. Arguing that these attempts at reductive analysis have invariably failed, John L. Pollock defends an alternative theory of conceptual analysis in this book. The author suggests that concepts should be analyzed in terms of their justification conditions rather than their truth conditions. After laying a theoretical foundation for this alternative scheme of analysis, Professor Pollock applies his theory in proposing solutions to a number of traditional epistemological problems. Among the areas of knowledge discussed are perception, knowledge of the past, induction, knowledge of other minds, and a priori knowledge. Originally published in 1975.

This exciting new edition of the classic Contemporary Theories of Knowledge has been significantly updated to include analyses of the recent literature in epistemology. In addition, a new case is made for the strong connection between epistemology and artificial intelligence, as Pollock and Cruz argue that a necessary condition for the correctness of any epistemological theory is that it be possible to build an implemented artificial intelligence system on the basis of it. Like the first edition, Contemporary Theories of Knowledge, Second Edition is an excellent teaching tool, introducing the reader to the fundamental issues and approaches in the field of epistemology.
