This two-volume work, first published in 1843, was John Stuart Mill's first major book. It reinvented the modern study of logic and laid the foundations for his later work in the areas of political economy, women's rights and representative government. In clear, systematic prose, Mill (1806–73) disentangles syllogistic logic from its origins in Aristotle and scholasticism and grounds it instead in processes of inductive reasoning. An important attempt at integrating empiricism within a more general theory of human knowledge, the work (...) constitutes essential reading for anyone seeking a full understanding of Mill's thought. Volume 1 contains Mill's introduction, which elaborates upon his definition of logic as 'not the science of Belief, but the science of Proof, or Evidence'. It also features discussions of the central components of logical reasoning - propositions and syllogisms - in relation to Mill's theories of inductive reasoning and experimental method. (shrink)

Ambiguous terms are applicable to different kinds of things, but so are general terms, since a general kind may include various species. Thus a bank may be the side of a river or a certain kind of financial institution, and an animal may be a dog or a cat. Similarly, an ambiguous sentence is true in different kinds of situations, and so is a general sentence in that different specific situations may make the same general sentence true. Thus the sentence, (...) The bank collapsed yesterday,’ can be true of different varieties of banks, and the sentence, The animal is untrained,’ can be true of different varieties of animals. These similarities of ambiguity and generality have led many linguists and philosophers to confuse the two. Basic to this confusion is a failure to notice a difference in the scopes of disjunctions involved in ambiguity and generality. (shrink)

Record of papers given at a symposium held at the University of Texas at Austin, April 1967; includes; C.J. Fillmore - The case for case; E. Bach - Nouns and noun phrases; J.D. McCawley - The role of semantics in a grammar; P. Kiparsky Linguistic universals and linguistic change.

Geoffrey Leech stresses the contribution of semantics to the understanding of practical problems of communication and concept-manipulation in modern society.

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

Katz offers such a grammatical account, in which makes it possible for the first time to explain the illocutionary potential of sentences within grammar.

Semantics is a bridge discipline between linguistics and philosophy; but linguistics student are rarely able to reach that bridge, let alone cross it to inspect and assess the activity on the other side. Professor Kempson's textbook seeks particularly to encourage such exchanges. She deals with the standard linguistic topics like componential analysis, semantic universals and the syntax-semantics controversy. But she also provides for students with no training in philosophy or logic an introduction to such central topics in the philosophy of (...) language as logical form, truth, speech acts, analyticity, entailment and presupposition. The exposition throughout is deliberately argumentative rather than descriptive, introducing the student step by step to the major problems in theoretical semantics. Special emphasis is placed on the need to consider individual arguments within the overall perspective of semantics as an integral part of general linguistic theory. Written primarily as a textbook for undergraduates and graduates in linguistics departments, this book will also be useful to undergraduates in philosophy and in psychology where linguistics is a part of their course.

There are obvious benefits to be gained from the study of logic: heightened ability to express ideas clearly and concisely, increased skill in defining one's terms, enlarged capacity to formulate arguments rigorously and to analyze them critically. But the greatest benefit, in my judgment, is the recognition that reason can be applied in every aspect of human affairs.

It is a paradox, whose importance familiarity fails to diminish, that the most highly developed and useful scientific theories are ostensibly expressed in terms of objects never encountered in experience. The line traced by a draughtsman, no matter how accurate, is seen beneath the microscope as a kind of corrugated trench, far removed from the ideal line of pure geometry. And the “point-planet” of astronomy, the “perfect gas” of thermodynamics, or the “pure species” of genetics are equally remote from exact (...) realization. Indeed the unintelligibility at the atomic or sub-atomic level of the notion of a rigidly demarcated boundary shows that such objects not merely are not but could not be encountered. While the mathematician constructs a theory in terms of “perfect” objects, the experimental scientist observes objects of which the properties demanded by theory are and can, in the very nature of measurement, be only approximately true. As Duhem remarks, mathematical deduction is not useful to the physicist if interpreted rigorously. It is necessary to know that its validity is unaltered when the premise and conclusion are only “approximately true.” But the indeterminacy thus introduced, it is necessary to add in criticism, will invalidate the deduction unless the permissible limits of variation are specified. To do so, however, replaces the original mathematical deduction by a more complicated mathematical theory in respect of whose interpretation the same problem arises, and whose exact nature is in any case unknown.

Continuing the discussion of induction, Volume 2 concludes with Book VI, 'On the Logic of the Moral Sciences', in which Mill applies empirical reasoning to human behaviour. A crucial early formulation of his thinking regarding free will and necessity, this book establishes the centrality of 'the social science' to Mill's philosophy. (shrink)
