 How exactly might the distinction between stage level and individual level predicates give rise to existential vs. generic readings of bare plurals? The original proposal is due to Greg Carlson (1977), however Carlson himself later came to reject the basics of his account (Carlson 1989). More recent discussion can be found in Diesing (1992), Chierchia (1995), Kratzer (1995), Cohen and Erteschik-Shir (1997, 2002), Kiss (1998), and others.
