Abstract
Two conceptions of language have dominated philosophical reflection over the last century on the nature of language and linguistic understanding. The first is the calculus conception, advanced in various forms by Frege, Russell, the early Wittgenstein, Carnap, Dummett and Davidson. The second is the anthropological conception of language advanced in various forms by the later Wittgenstein, Strawson, and Grice. The purpose of the paper is to compare and contrast the two conceptions. The calculus conception assigns priority to the notions of truth and truth-condition, and to the assertoric mode. The anthropological conception assigns priority to use, meaning and explanations of meaning, and is indifferent to mode. The disagreements between the two conceptions are explored, and the further consequences of each conception are described
