ABSTRACT
The right to happiness represents a wide and complex issue, but above all it can be identified in many areas. A reference to this right can be seen first of all in the Italian Constitution, both by analyzing art. 2 and 3 and considering the right to happiness as a constitutional interest transversal to other rights, considered as a system. Even in the agreements between the State and religious confessions it is possible to identify the right to happiness, trying to consider them as catalog of rights and duties submerged by the aggregating and expansive capacity of the need for happiness and well-being. This contribution concludes with a look at the work of Pope Francis, who deals with happiness in the encyclicals Amoris laetitia and Laudato si’; in the first the concept of happiness is closely connected to that of marriage and family, in the second the right to happiness is defined as a right of all, a common aspiration, since the human being, as a creature of this world, «has right to live and be happy».
