1. This exchange was first brought to my attention by Galen Strawson.
2. I here suppress, without a moment’s real hesitation, all versions of Cartesian doubt. The embodied perspective is not meant as a solution to such problems, and their discussion would rapidly take us too far afield.
3. Esther Thelen, a much-loved colleague and an inspirational thinker, died in December 2004 at the age of 63. Her work on infant development, exemplified by Thelen and Smith (1994) and Thelen et al. (2001), stands as one of the key practical and theoretical demonstrations of the value and power of the embodied approach.
4. The term cognizing is here used to mark a notion of the mental that is broader than the one suggested by introspection and common sense alone. Where introspection and common sense might identify mind simply as a locus of beliefs, desires, hopes, fears, and so forth, the scope of the cognitive may include states and operations unearthed by science. Examples might include grammars (if psychologically real) and the states and operations implemented by low-level vision.
5. The reference here is to Clark and Chalmers’s (1998) treatment called “The Extended Mind”; see the discussion in the text. This article is reproduced in the appendix.
