Gilbert Ryle's book The Concept of Mind was published in 1949. According to Ryle, his "destructive purpose" was to show that "a family of radical category mistakes" is the source of the "official doctrine," that is, a "double-life theory," according to which "with the doubtful exception of idiots and infants in arms every human being has both a body and a mind." By numerous examples, Ryle showed quite forcefully how psychology and philosophy at the time were misled into asking the (...) wrong kinds of questions. More than 50 years have elapsed since the original publication of Gilbert Ryle's book and, as Ullin T. Place wrote shortly before passing away, Ryle's conceptual analysis is now due, if not overdue, for a comeback. The purpose of this paper is to discuss the persistent relevance of category mistakes to current problems in the analysis of behavior. (shrink)

A representation is a remnant of previous experience that allows that experience to affect later behavior. This paper develops a metatheoretical view of representation and applies it to issues concerning representation in animals. To describe a representational system one must specify the following: thedomainor range of situations in the represented world to which the system applies; thecontentor set of features encoded and preserved by the system; thecodeor transformational rules relating features of the representation to the corresponding features of the represented (...) world; themedium, or the representation's physical instantiation; and thedynamics, or how the system changes with time. In part because of the behaviorist assumption that the hypothetical, covert changes occurring in an organism during learning correspond to the overt physical changes that are observed, issues of representation in animal behavior have been largely ignored as irrelevant or misleading. However, it can be inferred that representations, acting as models of environmental regularities, operate at many levels of behavioral functioning, both cognitive and noncognitive. Objections to the use of this concept in explanations of animal behavior, based on the claim that it is indeterminate and on behaviorist considerations of parsimony, can be answered. Animal representations may be specialized in terms of tasks and species. Data from tasks involving spatial memory, delayed matching-to-sample, and sequence learning suggest some foundations for a general theory of animal representations. (shrink)

Contrary to the Aristotelian interpretation of Empedocles' views about cognition, according to which all cognition, like perception, is due to the compositional likeness between subject and object of cognition, this paper argues that when Empedocles says that we know one thing 'by' another (e.g. earth by earth or love by love), he is characterizing analogical reasoning, an intellectual activity quite different from perception (which is explained by the fit between effluences and pores). The paper also explores the idea that strife (...) and love describe, in addition to physical separation and composition, the mental activities of analyzing and composing. (shrink)
