Extremes mean borders, beyond which life ends, and a passion for extremism, in art and in politics, is a veiled longing for death.

An editorial interpretation.
Kundera suggests that extremes are edges where life stops, so being drawn to extremism, whether in art or politics, hides a wish for death. It's a claim about motive: pushing to the limit is a disguised attraction to ending.
