SEE AUTHOR'S BLURB FOR LEAFLETS This collection of papers by distinguished philosophers, psychologists, and physiologists reflects an interdisciplinary approach to the central question of cognitive science: how do we model the mind? Among the questions explored are the relationships (theoretical, reductive, and explanatory) between philosophy, psychology, computer science, and physiology; what should be asked of models in science generally, and in cognitive sciencein particular; whether theoretical models must make essential reference to objects in the environment; whether there are human competences that are resistant, in principle, to modelling; whether simulated thinking and intentionality are really thinking and intentionality; how semantics can begenerated from syntactics; the meaning of the terms `representation' and `modelling'; whether the nature of the `hardware' matters; and whether computer models of humans are `dehumanizing'.
