The origins of the word pragmatism lie in the Latin pragmaticus, linked in Roman times to being active and businesslike. For a while it had a negative connotation as excessive activity, in the sense of meddling or interfering. By the nineteenth century, however, pragmatism had become more positive. It referred to treating facts or events systematically and practically, being realistic and factual, aiming at what was achievable rather than what was ideal. Its origins as a philosophical construct go back to the eighteenth-century German philosopher Immanuel Kant.
