Abstract

My dissertation concerns the question of how our desires and beliefs explain our bodily movements. This study aims to show that the solutions given to this question by both token physicalists, including Donald Davidson, Jerry Fodor, and Fred Dretske, and a proponent of a commonsense approach, Lynne Rudder Baker, are unsatisfactory. Finally, I discuss Daniel Dennett and argue that his theory is the only choice we have. ;All of the five philosophers claim that reasons cause actions. Davidson's theory fails to answer the question at issue because, on his account, the intentional properties of reasons are causally inefficacious in producing bodily behavior. Although Dretske's and Fodor's theories do not have this problem, their accounts receive the challenge from externalists, who argue that our intentional properties are determined not only by intrinsic physicial properties, but also by our relation to the environment. Since our intrinsic physical properties determines our bodily behavior, intentional properties seem irrelevant to the production of bodily movements. In response to externalism, both Dretske and Fodor attempt to provide an account of intentionality. However, I argue that their accounts are unsatisfactory. A fortiori, they fail to show content has any explanatory role. ;Then I switch to Baker's commonsense approach. She rejects the Standard View of the physicalists, i.e., that to have a propositional attitude is to have a brain state that has propositional content, and endorses her 'Practical Realism.' I, however, contend that her rejection of the Standard View is not successful and that Practical Realism, being compatible with the Standard View, fails to provide any new insight into intentional explanation. So the question at issue is still unanswered. ;At the end, I discuss Dennett's theory, which also rejects the Standard View. According to Dennett, there is no ontological difference between our beliefs and the beliefs of a machine, a nation, and evolution, provided that their behavior can be interpreted from the intentional stance. Therefore, instead of providing an account of the intentional , Dennett attempts to dissolve our urge for such an account by "demystifying" our intentionality
