This article provides an in-depth analysis and discussion of Plutarch, De curiositate ch. 11, wherein the ancient author advises his readership against any in-depth engagement with written offerings of the lettered world that they inhabit. Reading inscriptions, Plutarch appears to argue, is a slippery slope towards meddlesome behaviour, and it ought to be avoided (especially since inscriptions have little to offer that is of profound interest). Careful analysis demonstrates, however, that Plutarch’s actual line of argument is rather more nuanced and subtle: purpose of interaction and focus of one’s activity are important aspects to consider. Based on the implication of Plutarch’s argument, namely that engaging with written texts (even when they are on public display) might be deemed somewhat intrusive, a number of relevant inscriptions that address such privacy-related matters, are also revisited.
