The dualistic nature of humans has been recognized for centuries. The intriguing question is the extent to which the human being with her/his display of concern for others can simultaneously act as an egoist, the latter being descriptive of the homo oeconomicus rendition of the human.

Empirical evidence supports moving toward an expanded version of the mono-utility or I-utility model to include a We-utility.
