Thus, the crucial feature of intelligible emergence, according to Strawson, is that the relationship between the product of emergence and its producer can be adequately characterized using a single set of conceptually homogeneous concepts. But it’s very hard to see how any set of conceptually homogeneous concepts could capture both the experiential (i.e., consciousness-involving) and the non-experiential (non-conscious-involving), and hence hard to see how the thesis that consciousness emerges from non-consciousness could be rendered intelligible. Strawson argues that it is only by supposing that human and animal consciousness emerges from more basic forms of consciousness, that we have hope of avoiding the emergence of animal consciousness being a brute and inexplicable miracle.
