Abstract
We argue that the dynamical and computational hypotheses
are compatible and in fact need each other: they are about different
aspects of cognition. However, only computationalism is about the
information-processing aspect. We then argue that any form of
information processing relying on matching and comparing, as
cognition does, must use discrete representations and computations
defined over them.
