Hello Eduardo and Terry, I must say that I don't understand what is at stake. It seems to me that there is a confusion between "theory" and "model". A theory (at least as I understand it) is declarative. A model is prescriptive. A theory can exist without any model; a model can exist without a theory behind. Because both of them often use the rethorics of the hard sciences, both might appear formal enough to support this confusion. The touchpoint between the two is when they are performative : when, within a given situation, they allow you to distinguish between "cause" and "consequence", for instance... But it seems to me that the scope of design escapes partly from formalism, and therefore that there is little benefit to gain from theory. Or, should I say : the benefits can be political (more respect, more funding, more teachers... more power etc.), and this can justify the effort; but are limited when we come to "the act of designing". This doesn't mean at all that I am against rigour : in the words, in the discourse, in practice. There is a need for clarification, articulation, concepts etc. But the challenge is to avoid falling into formalism. Maybe my lazyness puts me to think that if so many clever people have tried to develop theories of design that never went beyond a school and some books, it must be because something essential lies elsewhere and escapes.
