Stage levels, states, and the semantics of the copula

The paper investigates the issue whether the stage-level/individual level contrast introduced by Carlson 1977 requires the assumption of two homonymous copulas depending on the categorization of the predicative. We argue that instead of a uniform stage-level/individual level distinction we have to distinguish several similar but independent contrasts, none of which crucially depend on the semantics of the copula. In the second part of the paper, we concentrate on one group of phenomena-the distribution of weak subjects-and propose an explanation in terms of an interaction between topic/comment structure and aspectual properties of the predicate
