http://cogprints.org/4151/ Spare Me the Complements: An Immoderate Proposal for Eliminating the "We/They" Category Boundary A speculative hypothesis about how to eliminate the "we/they" distinction by rearing children (during early critical years) in "aggregates in flux" instead of in kinship-based families: A category cannot be formed from positive examples only: one must be able to sample both what is and what is not in a category in order to recognise the category at all. The basis for the distinction is the features shared by the members (invariants), and absent from the non-members. In "aggregates in flux," the individual members would be constantly varying (and unrelated, genetically). The only invariant would be that they are all human.
