The passions have vanished. After centuries of dominance in the ethical and scientific discourse of the West, they have been eclipsed by the emotions. To speak of the passions now is to refer to a relic of the past, the crumbling foundation of a once mighty conceptual empire that permeated all aspects of Western cultural life. Philosophical and scientific wars continue to be fought in these ruins; new encampments are built, rebels plot in the catacombs, and bold victors plant their flags on the highest peaks. But it is hard to escape the conclusion that now it is the emotions which reign supreme in affective science. It is in their terms that conflicts are fought and settled.
