One task of logic, Peirce held, is to classify arguments so as to determine the validity of each kind. His own classification is interesting because it includes a novel type of argument in addition to the two traditionally recognized types. It is the purpose of this paper to discuss what Peirce thought to be sufficiently distinctive about abduction to warrant calling it a new kind of argument. But since one finds in his writings on abduction a number of different views (...) it is first necessary to make a few remarks concerning the unity of Peirce's thought. (shrink)

Concepts and problems; The calculus of inductive probability; Alternative inductive logics and the justification of induction; Probability and action; The pragmatic theory of inductive probability; The logic of causal statements as a formal language; The logic of causal statements as a model of natural language; The dispositional theory of empirical probability; Cause and chance in space - time systems; The presupposition of theory induction; Chance, cause, and reason.

Because statements like ‘This object is soluble in aqua regia’ involve the causal modalities, we call them causal dispositional statements. Now while this involvement has long been recognized, no thorough examination of its exact nature has ever been made. One purpose of this paper is to begin such an examination. In Sec. 2 we will suggest an analysis of causal dispositional statements, and in Sec. 3 we will discuss some philosophic issues to which this analysis is relevant.

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)

In this paper I synthesize a unified system out of Peirce's life work, and name it Peirce's Evolutionary Pragmatic Idealism. Peirce developed this philosophy in four stages: His 1868–69 theory that cognition is a continuous and infinite social semiotic process, in which Man is a sign. His Popular Science Monthly pragmatism and frequency theory of probabilistic induction. His 1891–93 cosmic evolutionism of Tychism, Synechism, and Agapism. Pragmaticism: The doctrine of real potentialities, and Peirce's pragmatic program for developing concrete reasonableness. Peirce's (...) evolutionary conception of the cosmos is pantheistic, and he constructed it to reconcile religion with Darwinian evolution. (shrink)

But even with respect to inductive arguments there are a number of different philosophical problems. One is to make explicit the fundamental or most general pattern or patterns of inductive argument. Once these patterns are known a second and third problem arise. The second is to justify man's use of and faith in inductive arguments. And the third is to formulate some general propositions about nature which could reasonably be accepted by users of inductive arguments and which when added to (...) the premises of these arguments make them explicitly deductive.

_Biogea_ is a mixture of poetry, philosophy, science, and biography exemplary of the style that has made Michel Serres one of the most extraordinary thinkers of his age. His philosophical and poetic inquiry sings in praise of earth and life, what he names singularly as Biogea. In these times when species are disappearing, when catastrophic events such as earthquakes and tsunamis impale the earth, Serres wonders if anyone “worries about the death pangs of the rivers.” And for Serres, one can (...) ask the same question of philosophy as the humanities increasingly find themselves in need of defenders. Today, all living organisms discover themselves part of this Biogea. “Today we have other neighbors, constituents of the Biogea: the sea, my lover; our mother, the Earth, becomes our daughter; this beautiful breeze which inspires the spirit, a spiritual mistress; our light friends, the fresh and flowing waters.”.

The definition of “model of a system” in terms of a homomorphism of the states of the system is evaluated and an alternative definition in terms of sequence generators is proposed. Sequence generators are finite graphs whose points represent complete states of a system. Sequence generators include finite automata and other information processing systems as special cases. It is shown how to define models in terms of a projection operator which applies to any sequence generator which has an output projection (...) and yields a new sequence generator. A model produced by the projection operator is embedded in the system it models. The notion of embedding is discussed informally and some questions raised about the relations of deterministic, indeterministic, and probabilistic models and systems. (shrink)

We distinguish scanning switches, which only enumerate states, from function switches which transform input states into output states. For the latter we introduce a logical network symbolism. Our history of early computer switching begins with the suggestions of Ramon Lull and Gottfried Leibniz, surveys the evolution of mechanical scanning switches and the first mechanical function switches, and then describes the first electromechanical function switches. The main themes of the present paper are that William S. Jevons built the first substantial function (...) switch (his logical piano), and that his work led to the design by Allan Marquand of the first substantial electromechanical function switch, as well as to Charles S. Peirce's idea for an electrical general-purpose programmable computer. These events all occurred fifty years before the first general-purpose programmable computers were constructed (in the 1940's), but they had no influence. (shrink)

World-renowned philosopher, Michel Serres writes a text in praise of the body and movement, in praise of teachers of physical education, coaches, mountain guides, athletes, dancers, mimes, clowns, artisans, and artists. This work describes the variations, the admirable metamorphoses that the body can accomplish. While animals lack such a variety of gestures, postures, and movements, the fluidity of the human body mimics the leisure of living beings and things; what’s more, it creates signs. Already here, within its movements and metamorphoses, (...) the mind is born. The five senses are not the only source of knowledge: it emerges, in large part, from the imitations the plasticity of the body allows. In it, with it, by it knowledge begins. (shrink)

This selection from his speeches and writings reveals a political philosophy which is viable. even prophetic, in our own time. Burke's distrust of disembodied reason, his vision of the law of all nations, and his wide pragmatism speak to everyone concerned with maintaining the democratic freedoms in an age when millions are subject to the tyranny of abstract political ideas. -- back cover.

Volume 1 of the Writings and Speeches of Edmund Burke presents Burke's early literary writings up to 1765, and before he became a key political figure. It is the first fully annotated and critical edition, with comprehensive notes and an authoritative introduction. The writings published here introduce readers to Burke's early attempts at a public voice. They demonstrate in a variety of ways how determined he was to become involved in the social and intellectual life of his times. The one (...) work of Burke's early life which has long been recognized as having prime critical significance, the Sublime and the Beautiful, is naturally found here. In addition the volume includes the first fully edited version of other works which have been neglected, notably the Vindication of Natural Society, a substantial satire on current philosophical and religious thought, the Abridgement of English History and the Hints for an Essay on the Drama. The volume also prints reliable texts of his early poems and prose `characters' as well as the first complete text of The Reformer since it was first published in 1748. This was a weekly paper devoted principally to the Dublin cultural scene and was edited by Burke shortly after he graduated from Trinity College, Dublin. (shrink)

This, the last volume in the series, provides the keys to all the others. All letters to and from Burke are listed, and the material in the letters themselves analysed in a comprehensive general index.
