Allowing the addition of a description of
a second phenomenon that doesn't interact with the first. In this
case the conclusions that can be drawn about the combined narrative
are just the conjunction of the conclusions about the component
narratives. To infer the obvious consequences of events we need to
assume that some other events do not occur. In this paper, a major
novelty is that we do not assume that no other events occur. We only
state that there are no events that would cause an event in our
narrative to fail. Thus a narrative about stacking blocks will state
that the only block moving actions are those
mentioned. A block stacking narrative will not say that no traveling
events occur. Nor will a narrative about traveling makes claims about
what block stacking events happen. This allows non-interacting
narratives to be consistently conjoined.
Previous proposals could not conjoin two narratives, as they either
assumed that the events that happened were picked out by the result
function, or they assumed that the only events that occurred were
those mentioned.
