We never see “anti-self” or “self-sacrificial” models in economics because they’d break the discipline’s moral boundary, namely that every act, however generous, must still fit inside the logic of self-interested utility.

it tends to set the reader himself in the track of invention, and to direct him into those paths in which the author has made his own discoveries, if he should be so happy as to have made any that are valuable.”

I agree that it isn’t constructive to conclude that there are no benefits to math in economic analysis. But I rarely hear us economists admit or even acknowledge that there are indeed costs, not just benefits, of pursuing mathematical precision.

What if words, in fact, are not on a continuum with maths? They may share some underlying structures, but they operate differently on meaning and representation.
