Abstract
This paper aims to distinguish Wittgenstein’s concept of ‘form of life’ from other concepts or expressions that have been confused or conflated with it, such as ‘language-game’, ‘certainty’, ‘patterns of life’, ‘ways of living’ and ‘facts of living’. Competing interpretations of Wittgenstein’s ‘form of life’ are reviewed, and it is concluded that Wittgenstein intended both a singular and a plural use of the concept; with, where the human is concerned, a single human form of life characterized by innumerable forms of human life
