The philosophies of substance presuppose a subject which then encounters a datum. This subject then reacts to the datum. The process ontology presupposes a datum (firstness) which is met with feelings (secondness), and progressively attains the unity of a subject (thirdness). It is in this sense that our bodily experience is primarily an experience of the dependence of the actual presentational immediacy upon the virtual causal efficacy, and not the other way round. To put it bluntly, the world does not emerge from the subject, but processes of subjectification emerge from the interactions between the body and world. The chapter is meant to provide the basis for the panel that will stage an encounter between cognitive neurosciences and architecture.
