Complementarity of Description and the Promise of Semiotics in Dealing with an Eluding ObjectA Commentary on Terrence W. Deacon’s “How molecules became signs”

I emphasize the general character of the central claim made by Terrence Deacon about the necessity of complementary description of evolving cognitive systems. Next, I clarify and augment one of the claims made in the paper about the tools offered by information theory. Finally, I point to the need of further clarification of some central notions, which should help to make connections across discourses.
