Contemporary #panpsychism is often focused on the idea that standard subjects are composed of very small microsubjects, that are identical to microphysical entities or strictly connected with them. Subjects made of other subjects. This idea can then be exported to collectivities: macrosubjects composed of standard subjects.
The #mereology of all this is fascinating and scarcely explored. My first instinct is to say that it should work in a general, homogeneous way.
