 Beyond chemistry and biology there are other scientific domains where scientific progress suggests process-ontological redescriptions since the conceptual contents of the relevant scientific terms cannot, without problematic distortions, be analyzed in terms of the categories of substance metaphysics. However, there are also scientific domains and topics that directly imply a process-ontological interpretation since the researchers working in these areas already have adopted processist idioms in their informal glosses of mathematical descriptions and in their heuristic approach to the domain. Cases in point for a ‘process turn’ within science itself are (i) quantum physics, (ii) self-organization, and, most recently, (iii) cognition.
