Norma moral y cambio social : la aproximación de los filósofos.

The purpose of this article is to analyz:e the way in which three moral philoso· phers Aquinas, Hume, Kant have approached the relationship between moral norm and social change. To this aim, I take as a point of reference the institutionaliz:ation of the moral norm in the traditional division of duties; this approach reveals itself as a promising path, to explore the way in which modern social theory has recogniz:ed the effect of social change on the strength with which the moral bond presents itself in consciences.
