Abstract
The aim of the present article is to analyse a constitutive trait of modern economic science in the light of Rosmini’s Principles of Moral Science. The meant trait is described with the formula «loss of reality» and is assumed to reveal structural criticalities of modern eco-nomic science which affects its relation to reality and thus implies the risk to compromise its research findings. The analysis is based on Rosmini’s understanding of the moral good, which, unlike other goods, extends to all human actions and is in all of them the same.
