This paper presents Amartya Sen's view on the possibility of social choice as a comparative and reflexing exercise with committed individuals, having as starting point John Rawls' Justice as equity. The argument is that to act by commitment and the various social identities one develops during his/her life - considering a concept of individual that is not the rational and self-interested individual of traditional Economics - are ways for developing Sen's thinking related to process of social choice through public reasoning, without to adopt the concept of restrict rationalism like is proposed in Economics.
