 Sticking with the propositional notion of content, for simplicity, we can also note the different kinds of “vehicles” through which that content can be conveyed. For example a particular token sentence “There is snow on Mt. Washington” conveys the content there is snow on Mt. Washington. But there may be other vehicles for such content as well, including mental vehicles, such as the act of judging that there is snow on Mt. Washington, or the event of seeing that there is snow on Mt. Washington. For the purposes of our toy example, all of these different vehicles convey the same abstract propositional content, which sets the correctness conditions for each instance.
