Abstract
Understanding is a ‘language event’ founded upon a ‘silent agreement’ between participants in a conversation. This silent agreement, built up of conversational aspects held in common, is what makes social solidarity possible and shows that the methods of science are an inappropriate starting point for our self-understanding. However, with the advent of industrial technical civilization, the question arises whether understanding has come under the control of a centrally steered communication system where language is a consciously wielded instrument of politics with a corresponding loss of free insight and critical judgement. Only via a hermeneutic logic of words, which begins from recognition that words get their meaning from the open space of living conversation, can critical judgement be defended in the face of the authority of science and technology
