Abstract
In “How Molecules Became Signs”, Prof. Deacon outlines a plausible mechanism whereby biochemical systems could be understood to fulfill the conditions of being “alive” in the context of the two broad families of requirements, namely the energetics of metabolism and the informatics of coding. In so doing, he addresses head-on how to account for the origin and the action of coding in physical systems, and thereby the necessary and sufficient conditions for life. I review some of the relevant issues around the interlocking potential necessary and sufficient conditions whereby these two phenomena are included within systems of interpretation in organisms.
