I offer a novel interpretation of Aristotle's psychology and notion of rationality, which draws the line between animal and specifically human cognition. Aristotle distinguishes belief (doxa), a form of rational cognition, from imagining (phantasia), which is shared with non-rational animals. We are, he says, “immediately affected” by beliefs, but respond to imagining “as if we were looking at a picture.” Aristotle's argument has been misunderstood; my interpretation explains and motivates it. Rationality includes a filter that interrupts the pathways between cognition (...) and behavior. This prevents the subject from responding to certain representations. Stress and damage compromise the filter, making the subject respond indiscriminately, as non-rational animals do. Beliefs are representations that have made it past the filter, which is why they can “affect [us] immediately.” Aristotle's claims express ceteris paribus generalizations, subject to exceptions. No list of provisos could turn them into non-vacuous universal claims, but this does not rob them of their explanatory power. Aristotle's cognitive science resolves a tension we grapple with today: it accounts for the specialness of human action and thinking within a strictly naturalistic framework. The theory is striking in its insight and explanatory power, instructive in its methodological shortcomings. (shrink)

Mark Johnston claims the pragmatist theory of truth is inconsistent with the way we actually employ and talk about that concept. He is, however, sympathetic enough to attempt to rescue its respectable core using ‘response-dependence’, a revisionary form of which he advocates as a method for clarifying various philosophically significant concepts. But Johnston has misrepresented pragmatism; it does not require rescuing, and as I show here, his ‘missing explanation argument’ against pragmatism therefore fails. What Johnston and other critics including Putnam (...) have overlooked is the distinctive nature of the pragmatist strategy, specifically, that it is non-reductive, a characteristic it shares with a more promising form of response-dependence; what Johnston calls ‘Descriptive Protagoreanism’ (DP). In this paper I offer a defence of pragmatism and show how it might be re-articulated as a form of DP. (shrink)

The so-called missing explanation argument, put forward by Mark Johnston in the late 80’s purported to show that our ordinary concepts of secondary qualities such as the colours cannot be response-dependent. A number of flaws were soon found in the argument. Partly in response to the criticism directed at the original argument, Johnston presented a new version in 1998. In this paper I show that the new version fails, too, for a simple reason: the kind of explanation which Johnston claims (...) to be incompatible with a response-dependent account of the relevant concept is not an empirical explanation at all, but merely looks like one because of certain factors in Johnston’s stage- setting for the argument. (shrink)

I argue that there is a flaw in the way that response-dependence has been formulated in the literature, and this flawed formulation has been correctly attacked by Mark Johnston’s Missing Explanation Argument (1993, 1998). Moving to a better formulation, which is analogous to the move from behaviourism to functionalism, avoids the Missing Explanation Argument.
