This chapter contains a very brief introduction to kripkenstein, perhaps just framing an issue, followed by an example. It is followed by a short discussion and then a series of questions. It is very natural to think that words and sentences have meanings. The chapter notes that there seems to be a 'fact of the matter as to what a term means', there is mind-independent fact as to what a given term means. The example is an exercise in thought. The example presents a case involving mathematics. The questions are intended to get the philosophy students thinking about this 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.
