....however, might be highlighted for whatever pragmatic reasons are significant. In the remainder of this paper, I will not concern myself with (ii) and in only a limited way with (i) several companion papers examine the semantics of such terms in more detail [ Ortiz, 1993; Ortiz, 1994; Ortiz, 1996; Ortiz, 1997 ] 1.2 Organization of paper The remainder of this paper is organized as follows. In Section 2 I review possible worlds and information change approaches to the semantics of counterfactuals and discuss technical problems. I then present a representation language and its semantics in Section 3; ....
....al. 1991 ] and the definition of causes simply requires that one have some way of blocking the identification of cases of generation with bona fide cases of causation. The relation of Goldman, Pollack s and Israel et al. s formulation to the one which follows is discussed elsewhere [ Ortiz, 1996; Ortiz, 1997 ] Here, I identify a method of relation counterfactually but require that the agent of both actions be the same as well as the time of performance. 34 Definition 6.7 (Method of performing an action) Let dur(ff; d) be true just in case d is the duration of ff. Then, j= occurs(ff; t) method ....

....theories of intention. This then leads to the specification of an agent architecture. 1 Representation language The representation language called Hypothetical Logic (HL ) in which the architecture will be specified is based on previous work on causation and rational action [Ortiz, 1996; Ortiz, 1999a] HL is a sorted modal first order language with sorts for events, times, fluents (properties of the world that change with time) and objects. The language contains two predicates: occurs(e; t) reports the occurrence of event type e at time t, and holds(f; t) reports that fluent f is true at ....
