Repeatedly and successfully, the celebrated Harvard philosopher Robert Nozick has reached out to a broad audience beyond the confines of his discipline, addressing ethical and social problems that matter to every thoughtful person. Here Nozick continues his search for the connections between philosophy and "ordinary" experience. In the lively and accessible style that his readers have come to expect, he offers a bold theory of rationality, the one characteristic deemed to fix humanity's "specialness." What are principles for? asks Nozick. We (...) could act simply on whim, or maximize our self-interest and recommend that others do the same. As Nozick explores rationality of decision and rationality of belief, he shows how principles actually function in our day-to-day thinking and in our efforts to live peacefully and productively with each other. Throughout, the book combines daring speculations with detailed investigations to portray the nature and status of rationality and the essential role that imagination plays in this singular human aptitude.

A reading is offered of Carl Hempel’s and Thomas Kuhn’s positions on, and disagreements about, rationality in science that relates these issues to the debate between W.V. Quine and Rudolf Carnap on the analytic/synthetic distinction.

APA PsycNET abstract: This is the first volume of a two-volume work on Probability and Induction. Because the writer holds that probability logic is identical with inductive logic, this work is devoted to philosophical problems concerning the nature of probability and inductive reasoning. The author rejects a statistical frequency basis for probability in favor of a logical relation between two statements or propositions. Probability "is the degree of confirmation of a hypothesis (or conclusion) on the basis of some given evidence (...) (or premises)." Furthermore, all principles and theorems of inductive logic are analytic, and the entire system is to be constructed by means of symbolic logic and semantic methods. This means that the author confines himself to the formalistic procedures of word and symbol systems. The resulting sentence or language structures are presumed to separate off logic from all subjectivist or psychological elements. Despite the abstractionism, the claim is made that if an inductive probability system of logic can be constructed it will have its practical application in mathematical statistics, and in various sciences. 16-page bibliography.

Addressing a wide range of topics, from Newton to Post-Kuhnian philosophy of science, these essays critically examine themes that have been central to the influential work of philosopher Michael Friedman.

In the Preface to his best known work on moral philosophy, Kant states his purpose very clearly and succinctly: “The present groundwork is, however, nothing more than the search for and establishment of the supreme principle of morality, which already constitutes an enterprise whole in its aim and to be separated from every other moral investigation” (Groundwork 4:392). This paper will deal with the outcome of the first part of this task, namely, Kant’s attempt to formulate the supreme principle of (...) morality, which is the intended outcome of the search. It will consider this formulation in light of Kant’s conception of the historical antecedents of his attempt. (shrink)

It is my view that one essential difference between persons and other creatures is to be found in the structure of a person's will. Besides wanting and choosing and being moved to do this or that, men may also want to have certain desires and motives. They are capable of wanting to be different, in their preferences and purposes, from what they are. Many animals appear to have the capacity for what I shall call "first-order desires" or "desires of the (...) first order," which are simply desires to do or not to do one thing or another. No animal other than man, however, appears to have the capacity for reflective self-evaluation that is manifested in the formation of second-order desires. (shrink)

Rudolf Carnap is widely regarded as one of the most important philosophers of the twentieth century. Born in Germany and later a US citizen, he was a founder of the philosophical movement known as Logical Empiricism. He was strongly influenced by a number of different philosophical traditions, and also by the German Youth Movement, the First World War, and radical socialism. This book places his central ideas in a broad cultural, political and intellectual context, showing how he synthesised many different (...) currents of thought to achieve a philosophical perspective that remains strikingly relevant in the twenty-first century. Its rich account of a philosopher's response to his times will appeal to all who are interested in the development of philosophy in the twentieth century. (shrink)

For Quine all talk is in mediis rebus, is itself a physical phenomenon. To grasp what a sentence is, its relation to a language, and what it is for a sentence to be true is to be invited to see that notions of shared meaning across languages, of truth, even of knowledge, are far from what they are ordinarily taken to be. To read Quine reflectively is to plunge with him into the midst of things, shunning the vain support of (...) purported transcendental certainties or Archimedean points, and spurning claims of the intuitive clarity of meaning, thought, and belief, for in the midst of things they themselves are what are most lacking in clarity.

Perspectives on Quine, now available in paperback, is a collection of twenty-one new essays dealing with the thought of America's most distinguished living philosopher, Willard Van Orman Quine. After the editors' brief introduction to Quine's thought, the volume opens with an important new essay by Quine entitled Three Indeterminacies. The essays that follow, written by leading philosophers, are rich with insights into a wide variety of Quine's concerns ranging from logic and set theory to natural language, truth, evidence, natural kinds, (...) naturalized epistemology, and much more. Each essay concludes with a summary and response from Quine himself. (shrink)

W. V. Quine was the most important naturalistic philosopher of the twentieth century and a major impetus for the recent resurgence of the view that empirical science is our best avenue to knowledge. His views, however, have not been well understood. Critics charge that Quine’s naturalized epistemology is circular and that it cannot be normative. Yet, such criticisms stem from a cluster of fundamental traditional assumptions regarding language, theory, and the knowing subject – the very presuppositions that Quine is at (...) pains to reject. Through investigation of Quine’s views regarding language, knowledge, and reality, the author offers a new interpretation of Quine’s naturalism. The naturalism/antinaturalism debate can be advanced only by acknowledging and critiquing the substantial theoretical commitments implicit in the traditional view. Gregory argues that the responses to the circularity and non-normativity objections do just that. His analysis further reveals that Quine’s departure from the tradition penetrates the conception of the knowing subject, and he thus offers a new and engaging defence of Quine’s naturalism. (shrink)

1. Introduction. It is generally admitted that a large part of man's knowledge is based on inductive arguments. Hence any philosophical theory concerning the nature of inductive arguments constitutes an epistemological theory. Any such philosophical theory of induction must, if it is to be satisfactory, take adequate account of Hume's criticism of inductive arguments. One way of treating his criticism is to say that the validity of inductive arguments is in an important sense relative to some broad factual assumptions about (...) the general nature of the universe and that these general factual assumptions are presupposed in a certain way by the users of inductive arguments. Let us call any theory of this general type a postulate theory of induction. (shrink)

This book introduces a new approach to the issue of radical scientific revolutions, or "paradigm-shifts," given prominence in the work of Thomas Kuhn. The book articulates a dynamical and historicized version of the conception of scientific a priori principles first developed by the philosopher Immanuel Kant. This approach defends the Enlightenment ideal of scientific objectivity and universality while simultaneously doing justice to the revolutionary changes within the sciences that have since undermined Kant's original defense of this ideal. Through a modified (...) Kantian approach to epistemology and philosophy of science, this book opposes both Quinean naturalistic holism and the post-Kuhnian conceptual relativism that has dominated recent literature in science studies. Focussing on the development of "scientific philosophy" from Kant to Rudolf Carnap, along with the parallel developments taking place in the sciences during the same period, the author articulates a new dynamical conception of relativized a priori principles. This idea applied within the physical sciences aims to show that rational intersubjective consensus is intricately preserved across radical scientific revolutions or "paradigm-shifts and how this is achieved.

"Reconstructs and analyzes the Vienna Circle's protocol-sentence debate and the positions of the central theorists involved: Moritz Schlick, Rudolf Carnap, and Otto Neurath"--Provided by publisher.

The paper begins with consideration of Plato and Aristotle, but the question addressed in this essay is the following: What has been meant--and what role has been played--in the succession of doctrines of physics we have had since the seventeenth century, by notions of “power” and of “cause”? The essay concludes with consideration of field theories set in relativistic space-time.
