Cognitive sciences, including cognitive neurosciences, have provided important insights into the notions of awareness, implicit/explicit information processing in knowledge, perception, object identification and memory, as well as general information retrieval. Meanwhile, propositional-attitude logics have coped with awareness in terms of symbolic tools, but are lacking the pathways by which to relate the two fields. I argue that empirical findings concerning rare neural dysfunctions (blindsight, unilateral neglect, prosopagnosia, implicit memory) contribute to logical investigations. On the other hand, the early phase on cognitive science, the origins of which coincide with that of pragmaticist philosophy, shared roots with phenomenology. Accordingly, I will identify strands in that early period that have surfaced in logic, AI and computer science. In phenomenology, the significance of the division between implicit and explicit aspects of knowledge in understanding cognition was ackno...
