Three features set this book apart from other recent publications on aspect. First, it looks closely at the language family, Slavic, that has been the main source of assumptions and data about aspect. Second, it looks upon the object of linguistic study, natural language, from an angle shared by thinkers on language whose prominence is still outside linguistics: Wittgenstein, Bakhtin, and Derrida. Third, the exploratory and contrastive account of aspect in Indic, chiefly in Bengali, which will no doubt evoke reactions from experts in these languages.
