ABSTRACT
This chapter contains a very brief introduction to verification in language, perhaps just framing an issue, followed by an example. It is followed by a short discussion and then a series of questions. A more interesting version of a verification principle of meaning might say something like, a claim is meaningful if and only if we know, in principle, how to verify whether it's true or false. The example is an exercise in thought. The example presents a case on Newton's law of universal gravitation. The questions are intended to get the philosophy students thinking about the problems. They have used these kinds of questions in seminars as the questions set for seminars, so they also think that they can be used to spark conversation and discussion. The chapter also gives a cursory sketch of some of the ways in which philosophers have responded to the thought experiment.
