The evolving conscious agent, II
摘要
The authors have previously studied an arbitrary agent’s potential awareness and, in terms of that, consciousness. The ontogenesis of a sufficiently sentient agent was expressed in terms of a policy for deciding the next action under its control, based on the phenomena of which it is aware. But like any other faculty of sentient beings, the resulting consciousness must have evolved. Moving to phylogenesis, the authors defend the view that an established mechanism, neural plasticity of the connectome, would support evolution of consciousness and to varying degree. A conceptual fitness space is introduced in which evolution might be traced, though for simplicity restricted to ‘Mendelian species’. The result allows the expression of random and environmentally-directed evolution, a combination of the two, and their in-principle quantitative comparison.
