Rationality of emotions

Esthetics and ethics are special cases of an attention (if not a study, a discourse, a logos...) to emotions.

In a modern view, this is antithetic to rationality. What makes emotions potentially rational, in a postmodern view, is the reference to bounded rationality (Herbert Simon or Daniel Kahneman).

One may also think of Heidegger's concept of blindness, as well as of Sartre's (borrowed from Henri Lefebvre) regressive analysis.

In such views, it is rational to acknowledge emotions, possibly to take them as a starting point for a regressive analysis, or for a discussion with others (e.g. indignation).

On the contrary, assuming a priori that ultimate rational causes exist and are reachable (explanations), is dangerous, and not grounded in reason.
