A theory of radical interpretation gives the meanings of all sentences of a language, and can be verified by evidence available to someone who does not understand the language. Such evidence cannot include detailed information concerning the beliefs and intentions of speakers, and therefore the theory must simultaneously interpret the utterances of speakers and specify (some of) his beliefs. Analogies and connections with decision theory suggest the kind of theory that will serve for radical interpretation, and how permissible evidence can (...) support it. (shrink)

During the last dozen years, Daniel Dennett has been elaborating an interconnected – and increasingly influential – set of views in the philosophy of mind, the philosophy of psychology, and those parts of moral philosophy that deal with the notions of freedom, responsibility, and personhood. The central unifying theme running through Dennett's writings on each of these topics is his concept of an intentional system. He invokes the concept to “legitimize” mentalistic predicates ("Brainstorms", p. xvii), to explain the theoretical strategy (...) of cognitive psychology and artificial intelligence, and, ultimately, to attempt a reconciliation between “our vision of ourselves as responsible, free, rational agents, and our vision of ourselves as complex parts of the physical world of science” (BS, p. x). My goal in this paper is to raise some doubts about the “intentional coin” (BS, p. xviii) with which Dennett proposes to purchase his moral and “mental treasures.”. (shrink)

1. When we attribute beliefs, desires, and other states of common sense psychology to a person, or for that matter to an animal or an artifact, we are assuming or presupposing that the person or object can be treated as an intentional system. 2. An intentional system is one which is rational through and through; its beliefs are those it ought to have, given its perceptual capacities, its epistemic needs, and its biography…. Its desires are those it ought to have, (...) given its biological needs and the most practicable means of satisfying them…. And its behavior will consist of those acts that it would be rational for an agent with those beliefs and desires to perform. [beliefs + desires  action] 3. If rationality is absent, we cannot coherently ascribe beliefs at all. 4. Therefore, no experiment could demonstrate that people systematically invoke invalid or irrational inferential strategies.

In a short article called “Mid-Term Examination: Compare and Contrast” that epitomizes and concludes his book The Intentional Stance, D. C. Dennett (1987) provides a sketch of what he views as an emerging Interpretivist consensus in the philosophy of mind. The gist is that Brentano’s thesis is true (the intentional is irreducible to the physical) and that it follows from the truth of Brentano’s thesis that: strictly speaking, ontologically speaking, there are no such things as beliefs, desires, or other intentional (...) phenomena. But the intentional idioms are “practically indispensable,” and we should see what we can do to make sense of their employment in what Quine called an “essentially dramatic” idiom…. Not just brute facts , then but an element of interpretation…must be recognized in any use of the intentional vocabulary. (Dennett, 1987, p. 342)12 In this context, “making sense of” the prevalence of the intentional idiom is not explaining why it should be indispensable if there are no beliefs or desires for it to refer to. Nor is it specifying the truth conditions of intentional attribution inevitably involves “an element of interpretation.” The discussion that follows treats these two papers together. (shrink)
