Darwin discusses why different muscles are brought into action under different emotions and how particular animals have adapted for association with man.

Introduction The analytical way of thinking has been one of the most fruitful paradigms in this century in philosophy and in different sciences, ...

The explanation of animal communication by means of concepts like information, meaning and reference is one of the central foundational issues in animal behaviour studies. This book explores these issues, revolving around questions such as: • What is the nature of information? • What theoretical roles does information play in animal communication studies? • Is it justified to employ these concepts in order to explain animal communication? • What is the relation between animal signals and human language? The book approaches (...) the topic from a variety of disciplinary perspectives, including ethology, animal cognition, theoretical biology and evolutionary biology, as well as philosophy of biology and mind. A comprehensive introduction familiarises non-specialists with the field and leads on to chapters ranging from philosophical and theoretical analyses to case studies involving primates, birds and insects. The resulting survey of new and established concepts and methodologies will guide future empirical and theoretical research. (shrink)

In this article I evaluate recent attempts to illuminate the human infant cry from an evolutionary perspective. Infants are born into an uncertain parenting environment, which can range from indulgent care of offspring to infanticide. Infant cries are in large part adaptations that maintain proximity to and elicit care from caregivers. Although there is not strong evidence for acoustically distinct cry types, infant cries may function as a graded signal. During pain-induced autonomic nervous system arousal, for example, neural input to (...) the vocal cords increases cry pitch. Caregivers may use this acoustic information, together with other cues, to guide caregiving behavior. Serious pathology, on the other hand, results in chronically and severely abnormal cry acoustics. Such abnormal crying may be a proximate cause of adaptive infant maltreatment, in circumstances in which parents cut their losses and reduce or withdraw investment from infants with low survival chances. An increase in the amount of crying during the first few months of life is a human universal, and excessive crying, or colic, represents the upper end of this normal increase. Potential signal functions of excessive crying include manipulation of parents to acquire additional resources, honest signaling of need, and honest signaling of vigor. Current evidence does not strongly support any one of these hypotheses, but the evidence is most consistent with the hypothesis that excessive early infant crying is a signal of vigor that evolved to reduce the risk of a reduction or withdrawal of parental care. Key Words: colic; crying; early infant crying; honest signaling; infanticide; parental care; parent-offspring conflict; separation call; vocalization. (shrink)

Researchers typically define animal signaling as morphology or behavior specialized for transmitting encoded information from a signaler to a perceiver. Although intuitively appealing, this conception is inherently metaphorical and leaves concepts of both information and encoding undefined. To justify relying on the information construct, theorists often appeal to Shannon and Weaver’s quantitative definition. The two approaches are, however, fundamentally at odds. The predominant definition of animal signaling is thus untenable, which has a number of undesirable consequences for both theory and (...) practice in the field. Theoretical problems include conceptual circularity and running afoul of fundamental evolutionary principles. Problems in empirical work include that research is often grounded in abstractions such as signal honesty and semanticity, and thereby distracted from more basic and concrete factors shaping communication. A revised definition is therefore proposed, making influence rather than transmission of encoded information the central function of animal signaling. This definition is conceptually sound, empirically testable, and inclusive, yet bounded. Implications are considered in both theoretical and empirical domains. (shrink)

This volume consists of the first of the John Dewey Lectures delivered under the auspices of Columbia University's Philosophy Department as well as other essays by the author. Intended to clarify the meaning of the philosophical doctrines propounded by Professor Quine in 'Word and Objects', the essays included herein both support and expand those doctrines.

This is a formal and systematic study of the logical foundations of speech act theory. The study of speech acts has been a flourishing branch of the philosophy of language and linguistics over the last two decades, and John Searle has of course himself made some of the most notable contributions to that study in the sequence of books Speech Acts, Expression and Meaning and Intentionality. In collaboration with Daniel Vanderveken he now presents the first formalised logic of a general (...) theory of speech acts, dealing with such things as the nature of an illocutionary force, the logical form of its components, and the conditions of success of elementary illocutionary acts. The central chapters present a systematic exposition of the axioms and general laws of illocutionary logic. (shrink)

Written in an outstandingly clear and lively style, this 1969 book provokes its readers to rethink issues they may have regarded as long since settled.

As is shown in the introduction of the book, the notion "illocutionary act" is used with quite a number of essentially different meanings; consequently, it is quite unclear what an "illocutionary act" is actually supposed to be. This problem is the starting point of the thesis. An argument is stated, to the effect that the introduction and use of scholarly terms like, for instance, "illocutionary act", or "performative sentence", is not entirely arbitrary. It is argued that technical terms should not (...) be re-defined without a reason, but in the absence of reasons to the contrary should be used in the way in which they have originally been introduced. This argument is applied to the notion "illocutionary act". John L. Austin is the one who introduced this notion. Consequently, his conception of these acts should be adopted unless there are good reasons to the contrary. Therefore the book provides a detailed analysis of Austin's account, and his original conception of these acts is reconstructed. The most popular alternative account of "illocutionary acts" is John R. Searle's. Therefore, secondly, the book provides an analysis of Searle's famous account of "illocutionary acts" - the first really detailed one available, including Searle's own work. It is shown that what Searle presents is in fact extremely sketchy, and can certainly not be viewed, as it often is, as an elaborated theory. It is further argued that the fundamental assumptions about language which Searle intends to illustrate with his account of "illocutionary acts" are mistaken, so that in general a theory following the lines Searle suggests is doomed to failure. Finally it is shown that Searle's account of "illocutionary acts", as far as it goes, is not an adequate adoption of the conception Austin introduced. Hence Searle's account is no reasonable alternative to Austin's account. (shrink)
