The 'CS:CD' reference is to Cognitive Development (3rd ed.), by J.H. Flavell, P.H. Miller, and S.A. Miller, Prentice Hall: 1993.Glenn Miller wrote:The concept of an inner self is found in children before the age of three [JCS:1.2.3]. Folk psychology is probably present from birth (see data given above). Young kids distinguish between 'mental' and 'physical' at a VERY early age [JCS:3.1.61]. "Infants' emerging concepts of others, the self, and social relations my reflect a beginning awareness of the mind, which blossoms into a theory of mind during the preschool years" [CS:CD:188]. Certain simian groups (chimps, orangutan, some gorillas; but not gibbons, baboons, monkeys) have a definite sense of self [CS:CD.205]. Bonobo apes have been known to develop a 'theory of the mind' similar to that of children [JCS:3.3.280]
This is rather strong evidence that concepts of mind are NOT acquired but are part-and-parcel of our very nature, and therefore makes a contribution to our survival, development, and/or actualization.
I'd like to hear some scientifico-philosophical thoughts on this.
