But your posting prompts me to ask a question in the semantics underlying applications of cateogories. What is the underlying metaphysics of perception (event, processes, relations ?). How do you capture 'time'. It seems to me the dynamism is in the arrows -- and there perhaps is where time comes in. It has always seemed to me that the applications of Cat. The. (for example in the study of Dynamical Systems) has served as a language to talk about mathematical, computatianal and procedural complexities ONCE THESE ARE ALREADY IN PALCE. Cat. is not to replace them as an alternative. Dr. Farogh Dovlatshahi > > > > Dear Colleagues, > > I am applying tools of category theory to research in artificial > perception and cognition.
