Ethologists and others studying animal behavior in a spirit are in need of a descriptive language and method that are neither anachronistically bound by behaviorist scruples nor prematurely committed to particular Just such an interim descriptive method can be found in intentional system theory. The use of intentional system theory is illustrated with the case of the apparently communicative behavior of vervet monkeys. A way of using the theory to generate data - including usable, testable data - is sketched. The (...) underlying assumptions of this approach can be seen to ally it directly with theorizing in evolutionary biology, which has recently come under attack from Stephen Gould and Richard Lewontin, who castigate it as the Their arguments, which are strongly analogous to B. F, Skinner's arguments against point to certain pitfalls that attend the careless exercise of such thinking (and rival varieties of thinking as well), but do not constitute a fundamental objection to either adaptationist theorizing or its cousin, intentional system theory.

This collection of 17 essays by the author offers a comprehensive theory of mind, encompassing traditional issues of consciousness and free will.

What is the relation between a reason and an action when the reason explains the action by giving the agent's reason for doing what he did? We may call such explanations rationalizations, and say that the reason rationalizes the action. In this paper I want to defend the ancient - and common-sense - position that rationalization is a species of ordinary causal explanation. The defense no doubt requires some redeployment, but not more or less complete abandonment of the position, as (...) urged by many recent writers. (shrink)

A detailed study of scientific theories of human nature and the possible ways in which human behavior can be predicted and controlled.

This essay has two goals. The first is to define the behavioristic study of natural events and to classify behavior. The second is to stress the importance of the concept of purpose.Given any object, relatively abstracted from its surroundings for study, the behavioristic approach consists in the examination of the output of the object and of the relations of this output to the input. By output is meant any change produced in the surroundings by the object. By input, conversely, is (...) meant any event external to the object that modifies this object in any manner. (shrink)

Action is to be distinguished from (mere) bodily movement not by reference to an agent's intentions, or his conscious control of his movements (Sect. I), but by reference to the agent as cause of those movements, though this needs to be understood in a way which destroys the alleged distinction between agent-causation and event-causation (Sect. II). It also raises the question of the relation between an agent and his neurophysiology (Sect. III), and eventually the question of the compatibility of purposive (...) and mechanistic accounts of human behaviour (Sect. IV). For the two to be compatible it is necessary that, e.g., intentions and brain states be not merely co-existent but also causal equivalents, in a way which allows for the mechanical explanation of teleological states — or vice versa.

William James's definition of psychology as 'the science of mental life' has been heard so often that we are apt to forget how radically it diverges from the view of psychology which so many of its practitioners hold today.

INTRODUCTION The appeal to teleological principles of explanation within the body of natural science has had an unfortunate history. ...
