This essay develops the relation, implicit in Essay 11, of intentional action to behaviour described in purely physical terms; Davidson repeats from Essay 3 that an action counts as intentional if the agent caused it, and asks to which degree a study of action thus conceived permits being scientific. Davidson stresses the central importance of a normative concept of rationality in attributing reasons to agents ; because this concept has no echo in physical theory, any explanatory schema governed by the (...) concept is irreducible to physical theory. Davidson adduces several facts that prevent us from giving strict laws connecting reasons and action: first, we cannot give conditions that are not only necessary but also sufficient for an action to be intentional, using only the concepts of belief, desire, and cause----for we cannot specify the ”right way’ in which beliefs and desires cause actions ; second, a certain holism of the mental pervades explanations of human behaviour: we cannot assign beliefs and desires independently of and prior to the actions they cause, a point Davidson takes Ramsey’s work on subjective probability to have shown. Davidson appends a set of replies to critics, which clarify his attitude to psychology as a science, his analysis of statements of law, the principle of causal interaction, and the relation between mutually irreducible explanatory schema.

From Descartes to Popper, philosophers have criticized and tried to improve the strategies of reasoning invoked in science and in everyday life. In recent years leading cognitive psychologists have painted a detailed, controversial, and highly critical portrait of common sense reasoning. Stephen Stich begins with a spirited defense of this work and a critique of those writers who argue that widespread irrationality is a biological or conceptual impossibility.Stich then explores the nature of rationality and irrationality: What is it that distinguishes (...) good reasoning from bad? He rejects the most widely accepted approaches to this question approaches which unpack rationality by appeal to truth, to reflective equilibrium or conceptual analysis. The alternative he defends grows out of the pragmatic tradition in which reasoning is viewed as a cognitive tool. Stich's version of pragmatism leads to a radical epistemic relativism and he argues that the widespread abhorrence of relativism is ill founded. (shrink)

It turned out that there was no phlogiston, no caloric fluid, and no luminiferous ether. Might it turn out that there are no beliefs and desires? Patricia and Paul Churchland say yes} We say no. In part one we give our positive argument for the existence of beliefs and desires.

Toward theory a homuncular of believing For years and years, philosophers took thoughts and beliefs to be modifications of incorporeal Cartesian egos. ...
