Efficiency and equity in economics always seem to be at odds. In terms of ultimate truth a dichotomy of this sort has little meaning because the use of a strategic rationality in the standard textbooks has privileged efficiency to the detriment of equality. In my estimation, this is a biased use of the concept implying that economic criteria are far from that of other social sciences. In this way, an incorrect alternative is presented: being scientific (economics) or being normative-political (other social sciences). Society does not maintain a unique equilibrium: Many different languages can live together and engage in communication with each other. Approaching the relation between efficiency and equity in economics as such can enrich the dialogue among sciences.
