This book offers a unique synthesis of past and current work on the structure, meaning, and use of negation and negative expressions, a topic that has engaged thinkers from Aristotle and the Buddha to Freud and Chomsky. Horn's masterful study melds a review of scholarship in philosophy, psychology, and linguistics with original research, providing a full picture of negation in natural language and thought; this new edition adds a comprehensive preface and bibliography, surveying research since the book's original publication.

The meanings of temporal adverbials seem easy to describe, but the compositional interaction with tense and aspect is notoriously difficult to analyse because we (more accurately: I) do not understand yet the principles governing the tense/aspect architecture of natural languages well enough. One of the most difficult areas of temporal structure is the perfect, and the literature quoted in this article shows that there is little agreement on its meaning(s). I believe that we will make progress only by a careful (...) investigation of the meanings of temporal adverbials and by stating their formal semantics in a way which is precise enough to test empirical predictions. This is what the present article wants to do. It studies the interaction of the German durative temporal PP seit a ‘since a’ with tense, in particular with the perfect. (shrink)

In English, [1e] occurs only in have got, but it is included here because of its importance in other languages. In Vedic Sanskrit and ancient Greek, for example, the perfect of many achievement predicates can be used to denote the result state. A good semantics of the perfect should therefore have something to say about it.

Our discussion is couched within a compositional implementation of the analysis of the Perfect developed by Iatridou et.al. (a version of Extended Now of McCoard 78, Dowty 72, 79). The basics.
