 Grice is a well-known critic of ordinary language philosophy, and one of his main targets was J. L. Austin and a style of reasoning he popularized. Austin thought there was a relatively clear notion of what it is inappropriate to say, and that we could delineate truth-conditions by identifying instances of inappropriateness (Warner, 2012). For example, he inferred from (1) “Typically, when one acts, it would be inappropriate to say either that one acted voluntarily or that one acted involuntarily” to (2) “Typically, when one acts, one acts neither voluntarily nor involuntarily.” As Grice convincingly argues, the inference fails because being untrue is not the only form of inappropriateness. Something may be true but inappropriate to say for other reasons (Grice 1960, 1975, 1981, 1989).
