Figure 6: 'Modern' human behaviour and the social construction of personhood. An accelerated rate at which knowledge is transmitted through social fields leads to the high-level scale domain of socially incorporated knowledge becoming sensitive to dynamics at both the intermediate level of the social construction of personhood, and the high process rate, low hierarchical level of knowledgeable action. The three scale domains of knowledge converge upon each other, becoming mutually sensitive and conditioning, so that socially incorporated knowledge and knowledgeable action are available for incorporation into the construction of personhood. Consequently social practices in which personhood is incorporated into the production of and engagement with socially received forms — symbolism — is enabled.
