Abstract

Prior's approach to time has been neglected by semanticists for several reasons. The main one, we believe, is the inability of Priorean tense logic to refer to times. The second one, is the inability to account for some important features of natural language such as temporal anaphora and the role of temporal constructions in discourse. Priorean tense logic has, however, one important advantage over other accounts: the internal perspective of time (due to its modal nature). This paper examines extensions of Priorean tense logic in which reference to times is possible, focusing on the so-called hybrid temporal logic. We will outline some of its main features and analyze some of its philosophical implications.
