    External Symbols Are a Better Bet Than Perceptual Symbols.A. J. Wells - 1999 - Behavioral and Brain Sciences 22 (4):634-635.
    Barsalou's theory rightly emphasizes the perceptual basis of cognition. However, the perceptual symbols that he proposes seem ill suited to carry the representational burden entailed by the architecture in which they function, given that Barsalou accepts the requirement for productivity. A more radical proposal is needed in which symbols are largely external to the cognizer and linked to internal states via perception.

    Rose's Homeodynamic Perspective is Not an Alternative to Neo-Darwinism.A. J. Wells - 1999 - Behavioral and Brain Sciences 22 (5):911-912.
    Lifelines discusses two approaches to biology, “ultra-Darwinism” which Rose criticises, and the “homeodynamic perspective,” which he offers as an alternative. This review suggests that ultra-Darwinism is a caricature of the theoretical positions Rose wishes to oppose and that the homeodynamic perspective is not an alternative, but is complementary to so-called ultra-Darwinism.
