What psychological and philosophical significance should we attach to recent efforts at computer simulations of human cognitive capacities? In answering this question, I find it useful to distinguish what I will call "strong" AI from "weak" or "cautious" AI. According to weak AI, the principal value of the computer in the study of the mind is that it gives us a very powerful tool. For example, it enables us to formulate and test hypotheses in a more rigorous and precise fashion. (...) But according to strong AI, the computer is not merely a tool in the study of the mind; rather, the appropriately programmed computer really is a mind, in the sense that computers given the right programs can be literally said to.

According to one influential philosophical view of human agency, for an agent to perform an action intentionally is essentially for her to manifest a kind of self-knowledge: An agent is intentionally φ-ing if and only if she has a special kind of practical and non-observational knowledge that this is what she is doing. I here argue that this self-knowledge view faces serious problems when extended to account for intentional actions performed by several agents together as a result of a joint (...) decision. This suggests that practical and non-observational knowledge is not essential to intentional action as such, since a theory of intentional action ought to be able to make sense of such paradigm cases of joint intentional action as well as cases of singular intentional action. Existing attempts to extend the self-knowledge view to joint intentional action face an unfortunate trilemma. These attempts must (i) require that participants have non-observational knowledge of each other’s non-observational knowledge, which in turn requires that the participants are either really one and the same agent, or that they are, for all relevant purposes, clones of each other; (ii) limit their explanatory scope to intentional actions performed by groups with a single decision maker at the top of an organisational hierarchy, which arguably are not really shared or jointly performed; or (iii) require that the intention of the group is the result of a public representational act that the group members will have observational knowledge of in a way that is incompatible with a core commitment of the self-knowledge view. I argue that each of these options is unacceptable given a self-knowledge view of intentional action. (shrink)

Experimental studies investigating the contribution of conscious intention to the generation of a sense of agency for one’s own actions tend to rely upon a narrow definition of intention. Often it is operationalized as the conscious sensation of wanting to move right before movement. Existing results and discussion are therefore missing crucial aspects of intentions, namely intention as the conscious sensation of wanting to move in advance of the movement. In the present experiment we used an intentional binding paradigm, in (...) which we distinguished between immediate intention, as usually investigated, and longer standing intention. The results showed that the binding effect was significantly enhanced for distal intentions compared to proximal intentions, indicating that the former leads to stronger sense of agency. Our finding provides empirical support for a crucial distinction between at least two types of intention when addressing the efficacy of conscious intentions. (shrink)

This paper explores R. W. Sperry's view that consciousness is ?causally? effective in directing voluntary human behaviour. This view, formulated in the course of his split brain research, presupposes an earlier theory that motor behaviour is the sole output of the brain and that mental phenomena were developed for regulation of overt response. His view of the ?causal? effectiveness of consciousness is shown to be based on a theory of emergent properties like that of Bunge. It is also shown that (...) Sperry, like Bunge, is a materialist; appearances to the contrary are due to occasional use of standard terms such as ?materialism? and ?interaction? in unusual senses. It is argued, with specific reference to Chisholm and Searle, that Sperry's hypothesis is helpful towards elucidating the structure and dynamics of action. It is also argued that it is not, as Sperry thinks, a consequence of his position that moral values are part of brain science. (shrink)

I argue that in order to solve the main difficulties confronted by the classical versions of the causal theory of action, it is necessary no just to make room for intentions, considered as irreducible to complexes of beliefs and desires, but also to distinguish among several types of intentions. I present a three-tiered theory of intentions that distinguishes among future-directed intentions, present-directed intentions and motor intentions. I characterize each kind of intention in terms of its functions, its type of content, (...) its dynamics and the rationality and time constraints that bear on it. I then try to show how the difficulties encountered by the causal theory can be solved within this new framework. 1. (shrink)

Nous appelons «thèse des descriptions multiples» l'opinion qui veut qu'une seule et même action peut etre decrite de plusieurs façons différentes selon que Ton prend en considération ou non les différentes conséquences, plus ou moins lointaines, de cette action. Cette thèse joue chez certains penseurs un rôle essentiel dans la solution du problème de l'individuation des actions. Chez D. Davidson notamment, elle intervient de façon décisive dans la démonstration de sa fameuse thèse que toute action se réduit à des mouvements (...) corporels. Nous entendons montrer, premièrement, que la thèse des descriptions multiples, à supposer même qu'elle soit vraie, ne saurait remplir le rôle que lui assigne Davidson dans le contexte de l'individuation des actions; deuxièmement, que cette thèse est fondée en fait sur l'ignorance de certaines distinctions importantes concernant l'action et le langage de l'action.

Agentive awareness is one's awareness of oneself as presently acting. Dominant accounts in cognitive science consider agentive awareness to be grounded in the states and processes underlying sensorimotor control. In this paper, I raise concerns for this approach and develop an alternative. Broadly, in the approach I defend, one is agentively aware in the virtue of intending to act. I further argue that agentive awareness is not constituted by intentions themselves but rather first-personal thoughts that are formed on the basis (...) of them. I develop this proposal, highlight some of its theoretical advantages, and show how it successfully meets various challenges. (shrink)

This paper discusses a problem arising from the way in which John Searle marks the distinction between intentional and unintentional action (Inquiry, Vol. 22, pp. 253?80), namely, that of adequately distinguishing those events which we regard as unintentional actions on the part of an agent from those other events occasioned by or brought about as a result of his action which we (correctly) do not countenance as actions of any sort ? unintentional or otherwise. Searle's attempt to distinguish them in (...) terms of the ?proximity of the contents of intentions? is examined and rejected, and an alternative account which exploits the anthropocentric character of our action vocabulary is proposed and defended. The discussion ends with a brief indication of some other difficulties engendered by Searle's analysis. (shrink)

John Searle’s account of collective intentions in action appears to have all the theoretical pros of the non-reductivist view on collective intentionality without the metaphysical cons of committing to the existence of group minds. According to Searle, when we collectively intend to do something together, we intend to cooperate in order to reach a collective goal. Intentions in the first-person plural form therefore have a particular psychological form or mode, for the we-intender conceives of his or her intended actions as (...) singular contributions by means of which – or: by way of which – a collective goal is pursued. Accordingly, we-intentions are held to have a psychological mode with a “collective goal by means of singular contribution” structure, which makes them primitive and irreducible to intentions in the I-form. It is further contended that, albeit primitive and irreducible, we-intentions are not the mental states of an alleged group mind but always of an individual’s mind. This paper targets Searle’s claim of irreducibility by developing an argument whose aim is to show that, pace Searle, it is possible to track the idea of intentions with a psychological mode structured in terms of “collective goal by means of singular contribution” back to the concept of intentions in the I-form. The argument mainly relies on the idea that Searle’s technical expressions “being a collective goal by means of singular contribution intention in action” or “being a collective goal by way of singular contribution intention in action” are susceptible to conceptual analysis. The upshot of this analysis is that we-intentions can be reduced to complex bundles of mental states, all of which come in the first-person singular form. If this argument is sound, Searlean we-intentions do not belong to a primitive kind of mental states. (shrink)
