A set of hypotheses is formulated for a connectionist approach to cognitive modeling. These hypotheses are shown to be incompatible with the hypotheses underlying traditional cognitive models. The connectionist models considered are massively parallel numerical computational systems that are a kind of continuous dynamical system. The numerical variables in the system correspond semantically to fine-grained features below the level of the concepts consciously used to describe the task domain. The level of analysis is intermediate between those of symbolic cognitive models (...) and neural models. The explanations of behavior provided are like those traditional in the physical sciences, unlike the explanations provided by symbolic models.Higher-level analyses of these connectionist models reveal subtle relations to symbolic models. Parallel connectionist memory and linguistic processes are hypothesized to give rise to processes that are describable at a higher level as sequential rule application. At the lower level, computation has the character of massively parallel satisfaction of soft numerical constraints; at the higher level, this can lead to competence characterizable by hard rules. Performance will typically deviate from this competence since behavior is achieved not by interpreting hard rules but by satisfying soft constraints. The result is a picture in which traditional and connectionist theoretical constructs collaborate intimately to provide an understanding of cognition. (shrink)

Josiah Royce (1855?1916) was, in addition to being the pre-eminent metaphysician at the turn of the 19th century in the USA, regarded as ?a logician of the first rank?. At the time of his death in 1916, he had begun a substantial and potentially revolutionary project in logic in which he sought to show the connection between logic and ethics, aesthetics, and metaphysics. His system was developed in light of the work of Bertrand Russell and A. B. Kempe and aimed (...) to include Russell's logic as a subsystem. This more comprehensive logic, which Royce called system Σ, brought together an analysis of the character of experience and knowledge with the principles which served to organize interests and direct actions. The result was to be a logical theory framed by ?a profoundly ethical motive as well as a genuinely intellectual one? that would serve as ?a theory of the way in which activities must go on if they go on at all?. This paper examines three stages in the development of Royce's logical system, its relation to the logic of Principia Mathematica, and prospects for its further development. (shrink)

Accustomed as many of us have become in the era of clinical bioethics to the idea of a “hospital philosopher”, on reflection the historical novelty of the role is astonishing, as are its ambiguities. As a result of considering my own experience I found myself writing this miniature intellectual autobiography. In the course of this essay I raise two specific questions: what can the Western philosophical tradition contribute to the clinical setting; and (a question that is rarely asked), what are (...) the implications of this experience for that tradition?

This is an examination of three main strategies used by engineering educators to integrate ethics into the engineering curriculum. They are: (1) the standalone course, (2) the ethics imperative mandating ethics content for all engineering courses, and (3) outsourcing ethics instruction to an external expert. The expectations from each approach are discussed and their main limitations described. These limitations include the insular status of the stand-alone course, the diffuse and uneven integration with the ethics imperative, and the orphaned status of (...) ethics using the outside expert. A fourth option is proposed — a special modular option. This strategy avoids the limitations of earlier approaches and harmonizes well with curricular objectives and professional values. While some help is provided by a professional ethicist, the headliner for the series of seminars is a high-profile engineer who shares an ethics dilemma encountered in professional practice. Students discuss the case and propose solutions. (shrink)

At present, there is a widely shared doubt about theoretical or practical validity of “nation state” as a framework to grasp the reality of the social. This doubt legitimately boils down to a more fundamental question, within or without the realm of social science, that is, whether or not the current conceptualization of the social is caught in a sort of anachronism that blocks thinking and acting in terms of transforming reality. In this paper, I would like to delineate the (...) situation not merely as a theoretical shortcoming of cotemporary social science but as a challenge: a call for reactivated social sensitivity. In an effort to meet this challenge, the socio-political significance of dialogue and human plurality as its critical element will be elaborated in search of cosmopolitan opening to the ways to think and act for the social in the making.

Abstract: Pragmatism involves simultaneous commitments to modes of inquiry that are philosophical and historical. This article begins by demonstrating this point as it is evidenced in the historicist pragmatisms of William James and John Dewey. Having shown that pragmatism focuses philosophical attention on concrete historical processes, the article turns to a discussion of the specific historiographical commitments consistent with this focus. This focus here is on a pragmatist version of historical inquiry in terms of the central historiographical categories of the (...) object of historical inquiry and mode of historical periodization. After describing the basic historiographical consequences of pragmatism's historicism, the article moves to a discussion of the philosophical results of this historicism. The focus here is on the role that historical inquiry can play in the general philosophical perspective of pragmatism as well as on some recent texts that exemplify the dual pragmatist commitment to philosophy and history.
