<strong>Presuppositions</strong> <strong>and</strong> <strong>Pronouns</strong><br />
utterance changes the situation in which it occurs, <strong>for</strong> example, <strong>and</strong> it causes<br />
changes in the interlocutors' cognitive states. It is this observation, I take it,<br />
which inspired the notion that the meaning of an expression must be defined<br />
in terms of the changes it would cause in a given context. In Heim's words:<br />
the meaning of an expression is its context change potential.<br />
At a technical level, DRT <strong>and</strong> dynamic semantics can be spelled out in such<br />
a way that they come to look quite similar, which is presumably what has<br />
fostered the myth that they are similar, <strong>and</strong> that any differences between the<br />
two theories are to be treated as domestic affairs. I maintain that this impres-<br />
impression<br />
is quite misleading: the differences between D DRT <strong>and</strong> dynamic<br />
semantics are so great that they can hardly be overstated.<br />
One of the ways in which DRT <strong>and</strong> dynamic semantics diverge is that they<br />
give rise to different theories of presupposition projection, which I will call<br />
the 'binding theory' <strong>and</strong> the 'satisfaction theory', respectively. The binding<br />
theory, which was first outlined by van der S<strong>and</strong>t (1987), is a version of DRT<br />
whose main tenet is that presuppositions are entities that want to be bound in<br />
the same sense in which anaphors want to be bound. When one thinks in<br />
DRT terms, this is a view that comes naturally: although it is theoretically<br />
possible to implement just about any account of presupposition in a DRT<br />
framework, the binding theory is the most obvious choice. The same can be<br />
said of the relation between dynamic semantics <strong>and</strong> the satisfaction theory of<br />
presupposition projection, which goes back to Heim (1983). The satisfaction<br />
theory requires that we adopt some version of dynamic semantics, <strong>and</strong> if one<br />
must deal with presupposition projection in a dynamic framework, it is<br />
almost frivolous to <strong>for</strong>go the satisfaction theory.<br />
The relation between the binding theory <strong>and</strong> the satisfaction theory<br />
resembles that between the semantic theories of which they are offshoots.<br />
Prima facie, they are so similar that it has been suggested that they are equiv-<br />
equivalent,<br />
but on closer inspection it appears that they are incompatible. Hence,<br />
these two theories <strong>and</strong> their frameworks arrange themselves in a square of<br />
opposition:<br />
