Two-way Brain-World Interaction
The host, Alan Saunders, prompts some discussion of the interactions between brain and world. Now, it seems to me that when Menary takes up this idea of this two-way symmetrical interaction between brain and world this can only be a description of a two-way symmetrical causal interaction between the brain and the world. But, while this sort of relation certainly exists and the EM folks often draw attention to this, the EM folks also want to say something other than just this. (That is, they want more than HEMC, they want HEC.) The EM folks want to say that, say, the iPhone or notebook is something like part of the realization base for someone's mental processes. But, realization is often taken to be a one-way lower- to higher-level determination relation. Or, maybe the EM folks want to say that the iPhone or notebook is something like the supervenience base for a person's mental states. This, too, however, is not a two-way brain-world interaction. It is something like a one-way lower- to higher-level determination relation.
