The papers collected in this issue address different topics at play in the contemporary debate on positive feeling and emotion by virtue of both their primary function in everyday life and their embedded structure. Within this issue, specific attention has been given to the intertwining of positive feeling and ethical issues according to different approaches whose goals consist in providing a description and clarification of the phenomena in question. The contributions gathered here give us a clear idea of the variety and possible nuances that define positive feelings and, with them, of the complexity of our lives and reality. Specifically, they concretely show the degree to which the quality of an experience depends on the agent-environment relationship, the benefits we can derive from certain positive experiences, and the extent to which the valence of an emotion can affect our moral life.
