Contemporary cognitive neuropsychology attempts to infer unobserved features of normal human cognition, or ‘cognitive architecture’, from experiments with normals and with brain-damaged subjects in whom certain normal cognitive capacities are altered, diminished, or absent. Fundamental methodological issues about the enterprise of cognitive neuropsychology concern the characterization of methods by which features of normal cognitive architecture can be identified from such data, the assumptions upon which the reliability of such methods are premised, and the limits of such methods—even granting their assumptions—in (...) resolving uncertainties about that architecture. With some idealization, the question of the capacities of various experimental designs in cognitive neuropsychology to uncover cognitive architecture can be reduced to comparatively simple questions about the prior assumptions investigators are willing to make. This paper presents some of simplest of those reductions. (shrink)

In the last thirty years, work in analytic philosophy of art has flourished, and it has given rise to considerably controversy. Stephen Davies describes and analyzes the definition of art as it has been discussed in Anglo-American philosophy during this period and, in the process, introduces his own perspective on ways in which we should reorient our thinking. Davies conceives of the debate as revealing two basic, conflicting approaches--the functional and the procedural--to the questions of whether art can be defined, (...) and if so, how. As the author sees it, the functionalist believes that an object is a work of art only if it performs a particular function (usually, that of providing a rewarding aesthetic experience). By contrast the proceduralist believes that something is an artwork only if it has been created according to certain rules and procedures. Davies attempts to demonstrate the fruitfulness of viewing the debate in terms of this framework, and he develops new arguments against both points of view--although he is more critical of functional than of procedural definitions. Because it has generated so much of the recent literature, Davies starts his analysis with a discussion of Morris Weitz's germinal paper, "The Role of Theory in Aesthetics." He goes on to examine other important works by Arthur Danto, George Dickie, and Ben Tilghman and develops in his critiques original arguments on such matters of the artificiality of artworks and the relevance of artists' intentions.

1. I want to discuss a new area of scientific research called neuro-aesthetics, which is the study of art by neuroscientists. The most prominent champions of neuroaesthetics are V.S. Ramachandran and Semir Zeki, both of whom have both made ambitious claims about their work. Ramachandran says boldly that he has discovered “the key to understanding what art really is”, and that his theory of art can be tested by brain imaging experiments, although he does not describe these experiments, or explain (...) what results the theory predicts (Ramachandran and Hirstein 1999, 17). Zeki, who originally coined the term “neuro-aesthetics”, claims to have laid the foundations for understanding “the biological basis of aesthetic experience”, and to have formulated a “neurobiological definition of art” (Zeki 1999, 2, 22). If these claims are true, we are at the dawn of a new age in the study of art. Up to now, most of the people studying art have been historians, some of whom can read Latin, but hardly any of whom have mastered even the rudiments of brain science. And aesthetics has been in the hands of philosophers, who still disagree among themselves about ideas that were stated in the fourth century BC. Neuroaesthetics is different. As Ramachandran (2000, 19) says: “These ideas have the advantage that, unlike the vague notions of philosophers and art historians, they can be tested experimentally”. So, is neuro-aesthetics the next big thing? I want to assess its prospects, starting with Ramachandran. (shrink)

The vivid terms, "Top-down" and "Bottom-up" have become popular in several different contexts in cognitive science. My task today is to sort out some different meanings and comment on the relations between them, and their implications for cognitive science.
