In this paper I examine the analogical argument that the use that is made of propositions in folk psychology in the characterisation of propositional attitudes is no more puzzling than the use that is made of numbers in the physical sciences in the measurement of physical properties. It has been argued that the result of this analogy is that there is no need to postulate the existence of sentences in a language of thought which underpin the propositional characterisation of propositional (...) attitudes in order to provide a naturalistic account of their use. I argue that a closer examination of the analogy implies rather than avoids the existence of structured representations constituting a language of thought, and thus that it should be abandoned by those who wish to avoid the postulation of such internal representations.

This paper (1) sketches a phenomenological analysis of visual mental imagery; (2) applies this analysis to the mental imagery debate in cognitive science; (3) briefly sketches a neurophenomenological approach to mental imagery; and (4) compares the results of this discussion with Dennett’s heterophenomenology.

Behavior that solves a problem is distinguished by the fact that it changes another part of the solver's behavior and is strengthened when it does so. Problem solving typically involves the construction of discriminative stimuli. Verbal responses produce especially useful stimuli, because they affect other people. As a culture formulates maxims, laws, grammar, and science, its members behave more effectively without direct or prolonged contact with the contingencies thus formulated. The culture solves problems for its members, and does so by (...) transmitting the verbal discriminative stimuli called rules. Induction, deduction, and the construction of models are ways of producing rules. Behavior that solves a problem may result from direct shaping by contingencies or from rules constructed either by the problem solver or by others. Because different controlling variables are involved, contingency-shaped behavior is never exactly like rule-governed behavior. The distinction must take account of a system which establishes certain contingencies of reinforcement, such as some part of the natural environment, a piece of equipment, or a verbal community; the behavior shaped and maintained by these contingencies; rules, derived from the contingencies, which specify discriminative stimuli, responses, and consequences, and the behavior occasioned by the rules.

This paper tries to remove some obstacles standing in the way of considering mental properties as both genuine natural kinds and causally efficacious rather than epiphenomena. As the case of temperature shows, it is not justified to conclude from a property being multiply realizable to it being irreducible. Yet Kim's argument to the effect that if a property is multiply realizable with a heterogeneous reduction base then it cannot be a natural kind and possesses only derivative “epiphenomenal” causal efficacy is (...) not conclusive either. The fact that temperature is, but jade is not, a natural kind cannot be established by comparing the heterogeneity of their respective reduction bases, but rather by the fact that the former is and the latter is not embedded in laws of nature.

Philosophers have often argued that ascriptions of content are appropriate only to the personal level states of folk psychology. Against this, this paper defends the view that the familiar propositional attitudes and states defined over them are part of a larger set of cognitive proceses that do not make constitutive reference to concept possession. It does this by showing that states with nonconceptual content exist both in perceptual experience and in subpersonal information-processing systems. What makes these states content-involving is their (...) satisfaction of certain basic conditions deriving from a general account of representation-driven behaviour that is neutral on the question of concept possession. It is also argued that creatures can be in states with nonconceptual content even though they possess no conceptual abilities at all. (shrink)

Abstract Is it plausible to claim (some) non?human animals have beliefs, on the (non?behaviourist) assumption that believing is or involves subjects? engaging in practical reasoning which takes account of meanings? Some answer Yes, on the ground that evolutionary continuities linking humans with other animals must include psychological ones. But (1) evolution does not operate?even primarily?by means of continuities. Thus species, no matter how closely related (in fact, sometimes even conspecifics) operate with very different adaptive ?tricks'; and it is plausible to (...) think these, rather than the physiological ?groundings? underlying them, are the best means of (analogies for) explaining beliefs. Also (2) it is reasonable to assimilate most cases ?down? to creatures (e.g. flies) that obviously lack beliefs rather than ?up? to others (chimpanzees) that apparently possess belief?like states (proto?beliefs), because observation shows the internal workings of such middle animals? ?beliefs? differ markedly from the corresponding things humans do. For example, ducks do not have beliefs about the numbers of objects, because although they estimate numerically, they do it in a way that is much more firmly connected to perceiving than would be the case either with counting or a counting?like process.
