Ionel,

I have read Essays several times. I cannot recall seeing either where 1)
Rosen rejects sets for relational modeling, or 2) mentions "'structured'
Categories" (for relational modeling, or anything else). In chapter 17 "What
Does It Take to Make an Organism?", where he discusses the (M,R)-system
model in detail, he refers to the components in the model as "sets" and as
"sets of mappings" (p. 261,262).

Tim
