To make sense of the ambiguous and complicated world we live in we need a way in which to perceive phenomena. For any given event there could be numerous causes and we instinctively choose the most significant cause. These causes are generally those that represent a human-like agent. Because these agents are not always easy to detect, we often assume that a human-like agent is behind the phenomena, regardless of whether we can identify its presence. He notes that Wegner, Mar, and Marcae propose that we are inclined to see action even in such things as geometric figures or "nonliving abstracts".
