The philosophy of emotions, and affective sciences more generally, have made huge progress in the last 50 years. Indeed, recent measures of publications show an exponential trend in emotion research, understanding emotions, and affective phenomena being thought by more and more disciplines, ranging from psychology to sociology and economics, to be key to understanding human affairs. As has recently been argued, it appears that in the wake of behaviorism and cognitive sciences, the present time is that of the rise of affectivism. The number of research efforts invested in understanding emotions is testimony to the importance of emotions. It is often repeated that emotions, in all their variety, are pervasive and indeed essential features of human lives. People have considered the nature of emotions and seen that emotions are best understood as felt evaluations, that can be assessed in terms of how they fit the world.
