Full Idea
If the soul had the nature of the body, it would have isolated members each unaware of the condition of the other;..there would be a particular soul as a distinct entity to each local experience, so a multiplicity of souls would administer an individual.
Gist of Idea
If soul was like body, its parts would be separate, without communication
