It's claimed that Bergson's "intuition of pure duration" is the "highest and most valuable form of human experience": is this an individualist or collectivist good?
I'm asking because I'm interested in the idea of cultural vitality, which is often I think considered a fascistic response to decadence. Especially how it might differ from how 'flourishing' appears in philosophical literature.
I thought maybe Bergson would could help me figure whether 'cultural vitality' is reasonable. Partly because Bergsonianism gets the ball rolling in Adorno's Negative Dialectics, and partly because he, along with the socialist proponent of violence Sorel, was important in forming the irrational (practice without theory) tendencies in the (often fascistic) historical avant garde.
More generally, how does Bergson, 'vitality' and 'flourishing' fit within Marxism?
