 Davidson (1967) gave an account of action sentences in terms of what is now widely known as events. The basic idea is that an action sentence has the form \((\exists e)(\cdots)\), where \(e\) is a variable over acts. For example, “Brutus violently stabbed Caesar” is translated (ignoring tense) as \((\exists e) (\mathop{\mathrm{stab}}(e,\mathrm{Brutus},\mathrm{Caesar}) \wedge \mathop{\mathrm{violent}}(e))\). This allows to capture the fact that this sentence logically entails that Brutus stabbed Caesar. This idea has been widely adopted in linguistics; moreover, it is now assumed that basically all verbs denote events (Parsons 1990). Thus action sentences are those that speak about special types of events, called eventualities.
