The article aims to make a contribution to the contemporary debate on emergence by focusing on Conwy Lloyd Morgan’s and George Herbert Mead’s theories of emergence. Both authors, in fact, first elaborated a theory that tried to synthesize the biological, the psycho-physiological and the social dimensions of emergent processes. Since Morgan’s emergentism and Mead’s processual ontology were conditioned by the reflections that the two thinkers had developed over the years and traces back their roots to the early 1890s, the article (...) will be developed as follows. A brief description of Morgan’s conception of organic and mental evolution as elaborated in the 1890s and summarised in his Lowell Lectures will be outlined. Then Mead’s early writings on psychophysics and comparative psychology, pointing out a similarity between Mead and Morgan’s ideas on organic and mental evolution at that time will be introduced. Finally, their theories of emergence from the 1920s, pointing out more interesting similarities and dissimilarities will be examined. (shrink)
