Abstract: This text collects all Austin’s published articles plus a new one, ch. 13, hitherto unpublished. The analysis of the ordinary language to clarify philosophical questions is the common element of the 13 papers. Chapters 2 and 4 discuss the nature of knowledge, focusing on ‘performative utterances’. The doctrine of ‘speech acts’, i.e. a statement may be the pragmatic use of language, is discussed in Chs 6 and 10. Chapters 8, 9, and 12 reflect on the problems the language encounters in discussing actions and consider the cases of excuses, accusations, and freedom. The ‘correspondence theory’, i.e. a statement is truth when it corresponds to a fact, is presented in Chs 5 and 6. Finally, Chs 1 and 3 study how a word may have different but related senses considering Aristotle’s view. Chapters 11 and 13 illustrate the meaning of ‘pretending’ and a Plato’s text respectively.
