In this paper we describe a cognitive model based on the Systemic approach and on the Autopoiesis theory. The syntactical definition of the model consists of logical propositions but the semantic definition includes, besides the usual truth value assignments, what we call emotional flavors, which correspond to the state of the agent’s body translated into cognitive terms. The combination between logical propositions and emotional flavors allows the agent to learn and memorize relevant propositions that can be used for reasoning. These propositions are represented in a specific format – prime implicants/implicates – which is enriched with annotations that explicitly store the internal relations among their literals. Based on this representation, a memory mechanism is described and algorithms are presented that learn a proposition from the agent’s experiences in the environment and that are able to determine the degree of robustness of the propositions, given a partial assignment representing the environment state.
