Janet / List:
You asked, in an earlier post, about the relations between Rosen and
They were longtime friends and exchanged correspondence for decades.
I would not attempt to go beyond a few sentences in describing the
relation of their works.
Ehresmann believes that a physical basis for biology / consciousness
Rosen attempted to show via his personal view of "modeling
relation" (not model theory!), that the mathematics of physics was
not the mathematics of life.
Both of them use the mathematics of category theory to construct
their philosophical positions.
From the perspective of chemical logic (for example, DNA - motivated
processes), neither of them seek to invoke the law of mass action or
other chemical principles in introducing time into their equations.
Thus, while I , personally, have benefited greatly from exchanges
with them, I long ago decided to construct a new path that is
consistent with chemical logic.
