Maxwell et al. [Maxwell, J. P., Masters, R. S. W., Kerr, E., & Weedon, E. . The implicit benefit of learning without errors. The Quarterly Journal of Experimental Psychology, 54A, 1049–1068. The implicit benefit of learning without errors. The Quarterly Journal of Experimental Psychology, 54A, 1049–1068] suggested that, following unsuccessful movements, the learner forms hypotheses about the probable causes of the error and the required movement adjustments necessary for its elimination. Hypothesis testing is an explicit process that places demands (...) on cognitive resources. Demands on cognitive resources can be identified by measuring probe reaction times and movement times. Lengthened PRT and movement times reflects increased cognitive demands. Thus, PRT and movement times should be longer following errors, relative to successful, movements. This hypothesis was tested using a motor skill . Furthermore, the association between error processing and the preparation and execution phases of movement was examined. The data confirmed that cognitive demand is greater for trials following an error, relative to trials without an error. This effect was apparent throughout learning and in both the preparatory and execution phases of the movement. Cognitive effort also appeared to be higher during movement preparation, relative to movement execution. (shrink)

Political action requires a concept of humanity grounded in an explicit notion of human nature. Feminists apprehensive about poststructuralism's implications for a feminist politics need methods and discourses that allow feminist politics to proceed toward a vision of human well-being. Recent work by Chris Weedon and Erica Sherover-Marcuse highlights the need for hypotheses that can guide efforts to dismantle oppressed habits of being and help women evaluate and develop political strategies for universal solidarity.

Emile Durkheim is widely lauded as one of the founding fathers of modern Sociology and for his substantial contribution to the sociology of education. This set brings some of his most important writings on the subject together for the first time.

Heidegger’s characterization of Dasein as Being-in-the-world suggests a natural relation to environmental philosophy. Among environmentalists, however, closer inspection must raise alarm, both since Heidegger’s approach is in some senses inescapably anthropocentric and since Dasein discovers its environment through its usability, serviceability, and accessibility. Yet Heidegger does not simply adopt a traditionally modern, instrumental view. The conditions under which the environment appears imply neither that the environment consists only of tools, nor that what is true of the parts is also true (...) of the whole, nor that an orientation to use—where appropriate—precludes any other orientation. Heidegger’s anthropocentric commitments thus do not rule out the possibility of a non-instrumental perspective on the natural world. (shrink)

Modern knowledge of servo systems and computing machines makes it possible to specify a circuit that can and will induce the rules and winning moves in a game like chess when they are given only ostensibly, that is, by playing against opponents who quit when illegal or losing moves are made. Such circuits enjoy a value social in the sense that it is shared by the players.La connaissance moderne des servomécanismes et des machines à calculer permet de concevoir un circuit (...) qui pourra suivre des règles et décider les coups décisifs dans un jeu comme le jeu d'échecs tout au moins quand les coups sont joués de faÇon apparente, c'est-à-dire contre des adversaires qui abandonneront dans le cas de coups irréguliers ou de coups absurdes.De tels circuits possèdent une „valeur” sociale dans la mesure où elle est partagée par les autres joueurs.Moderne Kenntnissen im Gebiete von Folgegeraeten und Rechenmaschinen ermoeglichen es einen elektrischen Kreis aufzuwerfen, der die Regeln und gewinnbringende Zuege eines Spieles wie Schach induktiv erfassen kann und wird, wenn diese Regeln und Zuege nur ostensiv gegeben sind; d.h. indem mit Gegnern gespielt wird, die das Spiel einstellen sobald regelwidrige oder verlustbringende Zuege gemacht werden. Solche Kreise schaffen demnach einen Wert, der gesellschaftlich in dem Sinn ist, dass er auch von den Mitspielern geteilt wird. (shrink)

Although other quasi-Kantian theories have been adapted, Jürgen Habermas’s discourse theory has been largely ignored in discussions of environmental ethics. Indeed on some versions of what an environmental philosophy must entail, Habermas’s anthropocentric approach must be disqualified from the start. Yet, there are some environmentally friendly implications of his discourse theory. They may not give us everything we would wish, but in the contemporary political context we must treasure any moral theory that can draw on the still-extensive theoretical and political (...) resources of liberalism.

Leclerc's systematic introduction is predicated upon the thesis that "Whitehead's basic problems belong to the great tradition of philosophical inquiry first opened up by the Greeks." A lucid discussion of the traditional problems surrounding "being" leads simply and logically to a consideration of the categories in terms of which Whitehead reformulates the traditional approach to "that which is." The great merit of this progression is that it dispels the illusion, so overwhelming on an initial glance at Whitehead himself, that his (...) terminology is arbitrary and completely disassociated from traditional usage.--D.

Whitehead's remarks on man, social problems, education, religion, and history have been extracted from his technical works and placed side by side to form an account in familiar terminology of Whitehead's theory of civilization. In context, occurring almost as afterthoughts illustrating abstract metaphysical principles, these remarks constitute brilliant flashes of humanistic insight; abstracted from context, they become platitudinous. Only when, in the final chapter, Johnson adumbrates their metaphysical setting, does one feel any of the excitement of seeing the values of (...) Western democracy emerge from a speculative account of the nature of things. --D. W. S. (shrink)

The authors' novel approach to some interesting mathematical concepts - not normally taught in other courses - places them in a historical and philosophical setting. Although primarily intended for mathematics undergraduates, the book will also appeal to students in the sciences, humanities and education with a strong interest in this subject. The first part proceeds from about 1800 BC to 1800 AD, discussing, for example, the Renaissance method for solving cubic and quartic equations and providing rigorous elementary proof that certain (...) geometrical problems posed by the ancient Greeks cannot be solved by ruler and compass alone. The second part presents some fundamental topics of interest from the past two centuries, including proof of G del's incompleteness theorem, together with a discussion of its implications. (shrink)

It is not my purpose to discuss the authorship of this work; I shall only say that I do not believe it was written by Quintus Cicero. The question of authorship cannot be brought into a discussion of the problems raised by the text, because, even if it were the product of Quintus' pen, it would obviously be unjustified to apply to Quintus the same canons of Latinity as can be applied to his brother.
