Collective Behavior, Learning and Emergent Phenomena

 We inevitably encounter some paradoxes when we consider emergent phenomena. Let’s take an example of the process when learning something new. We implicitly consider that learning is a process of treating unknown things as known. However, this explanation is a contradiction because unknown things would be considered as an ignorance of the observer. In this case, unknown things turn into known things because unknown things are just outside of known things. Then, what is “unknownness”of unknown things?
 We consider that the ambiguity of unknown things, which has an aspect of elements (token) and sets (type), ensures the “unknownness” that we point out. This ambiguity also allows us to discuss positively the learning process and the emergent phenomena. The ambiguity between type and token would be important when we understand flocking, schooling and swarming as one collective (The under figure is the picture of mictyris brevidactylus in Okinawa. Photographer: Yuta Nishiyama). The ambiguous relation between individuality (token) and society (type) in individuals makes the boundary between microscopic and macroscopic view invalid. As a result, a set of individuals moves as one collective. We are trying to elucidate emergent phenomena by using this method.
