This paper investigates the prospects of Rodney Brooks’ proposal for AI without representation. It turns out that the supposedly characteristic features of “new AI” (embodiment, situatedness, absence of reasoning, and absence of representation) are all present in conventional systems: “New AI” is just like old AI. Brooks proposal boils down to the architectural rejection of central control in intelligent agents—Which, however, turns out to be crucial. Some of more recent cognitive science suggests that we might do well to dispose of (...) the image of intelligent agents as central representation processors. If this paradigm shift is achieved, Brooks’ proposal for cognition without representation appears promising for full-blown intelligent agents—Though not for conscious agents. (shrink)

Xenophon’s conception of the dialectical method shares many similarities with Antisthenes’ point of view regarding the relation between language and reality. The key element supporting this reading is the parallel between Xenophon’s method of dialegein kata genē and Antisthenes’ method of episkepsis tōn onomatōn. In this paper, I claim that a correct understanding of both methods yields a clear structural proximity between the two Socratics on the issue of dialectics. Although they present some significant differences, which I will also explore, (...) I will argue that both variants express a single Socratic motive with regard to dialectics. That is that dialectics, in its basic structure, consists of organizing reality through discourse in order to make it comprehensible. In particular, this is done through establishing unified instances capable of comprehending a multiplicity. This nuclear position could also be extended to include middle Plato’s concept of dialectics. This concurrence takes up different forms in Plato, Xenophon and Antisthenes. Nevertheless, they share the same structure, which indicates quite plausibly a major characteristic of Socratic philosophies, as opposed to previous attempts by the Presocratics and the Sophists.

It is exceedingly frequent for people to speak of the ‘passing of time’. We do not, on the other hand, speak of the ‘passing of space’. There do not seem to be any common locutions concerning spatial passage analogous to those of time’s assumed passage. Further, there is a long held belief in the philosophy of time that there is no spatial analogue of the passage of time. This opinion does not take into account circumstances that cannot be noticed in (...) day-to-day existence and which indicate that there is such a spatial analogue. (shrink)

Using the notion of strict implication, Robert Kirk claims to have formulated a version of physicalism which is nonreductive. I argue that, depending on how his notion of strict implication is interpreted, Kirk's formulation either fails to be physicalist or else commits him to reductionism. Either way we do not have nonreductive physicalism. I also suggest that the reductionism to which Kirk is committed, though unfashionable, is unobjectionable.

Scientists disagree about which capacities a functional analysis of consciousness should target. To address this disagreement, I propose that a good functional analysis should target the etiological functions of consciousness. The trouble is that most hypotheses about the etiological origins of consciousness presuppose particular functional analyses. In recent years, however, a small number of scientists have begun to offer evolutionary hypotheses that are relatively theory neutral. I argue that their hypotheses can serve an independent standard for evaluating among theories of (...) consciousness. (shrink)
