The genetically-modified-organism (GMO) experience has been prominent in motivating science, industry, and regulatory communities to address the social and ethical dimensions of nanotechnology. However, there are some significant problems with the GMO-nanotech analogy. First, it overstates the likelihood of a GMO-like backlash against nanotechnology. Second, it invites misconceptions about the reasons for public engagement and social and ethical issues research as well as their appropriate roles in nanotech research, development, application, commercialization, and regulatory processes. After an explication of the standard (...) GMO-Nanotech analogy, these two problems are discussed in turn. (shrink)

This volume examines some of the arguments that have been put forward over the years to explain the way in which understanding is acquired. The author looks firstly at the empricist thesis of genesis without structure, and secondly at the opposing theory, represented by Chomsky of structure without genesis. His greatest sympathy is with the theory of Piaget, who represents structure with genesis. He considers that Piaget's account is flawed, however, by its biological model and by its failure to deal (...) adequately with the problem of objectivity. The second part of the book contains chapters on language, the differences between early and later learning, and on teaching. The book provides a general understanding of the principles that make it possible, and the differences between the ways in which they work at different stages. (shrink)

There has been a good deal of interest in recent years in what Franz Brentano had to say about the notion of ‘intentional objects’ and about intentionality as a criterion of the mental. There has been less interest in his classification of mental phenomena. In his Psychology from an Empirical Standpoint Brentano asserts and argues for the thesis that mental phenomena can be classified in terms of three kinds of mental act or activity, all of which are directed towards an (...) immanent object. These are, respectively, presentation, judgment and what he calls the phenomena of love and hate. Once again, less interest has been shown in what he has to say about the last of these three than in what he says about the others. I wish to take Brentano's views as the point of departure for a discussion of love and hate, since these notions seem to me to have a good deal of philosophical interest, for at least two main reasons. First, I have recently had some concern with the part that personal relations play in our understanding of others and of ourselves, and love and hate seem to be very important elements in such relations. Second, love and hate have long seemed to me to provide important counter-examples to some prevalent philosophical theories about the emotions. I shall take this issue first. (shrink)

D W Hamlyn; Need Philosophy of Education be so Dreary?, Journal of Philosophy of Education, Volume 19, Issue 2, 30 May 2006, Pages 159–165, https://doi.org/10.1.

Is it possible to do something intentionally and yet be unconscious of so doing? Many philosophers would answer ‘No’ to this question on the grounds that it is of the essence of intention that if we do something intentionally we do it knowing what we are doing.

For many years there has been a debate about the role of the parietal lobe in the generation of behavior. Does it generate movement plans (intention) or choose objects in the environment for further processing? To answer this, we focus on the lateral intraparietal area (LIP), an area that has been shown to play independent roles in target selection for saccades and the generation of visual attention. Based on results from a variety of tasks, we propose that LIP acts as (...) a priority map in which objects are represented by activity proportional to their behavioral priority. We present evidence to show that the priority map combines bottom-up inputs like a rapid visual response with an array of top-down signals like a saccade plan. The spatial location representing the peak of the map is used by the oculomotor system to target saccades and by the visual system to guide visual attention. (shrink)

ABSTRACT The article criticizes certain subjectivist and isolationist stances on controversial issues, and construes the teaching of controversial issues as an interpersonal task. On this view the teacher (1) encourages students to enter into the perspectives of others; (2) establishes points of contact which make reasoned discourse possible; and (3) inducts students into a wider domain where they are provided with knowledge about controversies as well as the skills for handling those controversies. All of this requires considerable intervention on the (...) part of the teacher. Current doubts about such intervention are unjustified. (shrink)

In a recent article [Mertz 2001] in this journal I argued for the virtues of a realist ontology of relation instances (unit attributes). A major strength of this ontology is an assay of ontic ('material') predication that yields an account of individuation without the necessity of positing and defending 'bare particulars'. The crucial insight is that it is the unifying agency or combinatorial aspect of a relation instance as predicable that is for ontology the principium individuationis [Mertz 2002; 1996]. Or (...) in short, what is ontically predicable, precisely as such, is the cause of individuation. As a preface to this positive doctrine I offered arguments against the coherence of bare particulars as defended in an article by J. P. Moreland [1998]. In a reply contained in this issue Moreland and Timothy Pickavance (hereafter M/P) propose to answer my objections [2002]. The response that follows provides reasons why, I contend, M/P have not succeeded in parrying my objections to bare particulars. (shrink)
