My view on this, for what it's worth, is that social phenomena, physical
phenomena, and cognitive phenomena invoke different logics, each of which
is valid in its own realm: Domain-specific phenomena; domain-specific
logic. Of course, this is not to say that these logics do not interact, or
are mutually exclusive. It cannot not be so. As such, I think, rather than
'unit of analysis' as an approach to studying "things" or "processes" (each
of which involves relationships between both clasifications), 'phenomena
under investigation' might be a better way to grasp the "things",
"processes", and "relationships" that constitute the boundaries of our
understanding of a given phenomenon in which we're interested. Hence,
domain-specific phenomenologies are suggested (S'cuse the absence of agency).
