‘To be persuaded means to have convictions. To know what you are convinced about implies that you discriminate between some matters you consider certain and others you regard as uncertain – matters of doubt. To make meaningful distinctions between convictions and doubts, one needs further to have a sense of how things doubted might cease to be doubted; that is, one needs a concept of warrants, of what may be persuasive. People can be in doubt about something and feel unsure if or how it can ever become for them a matter of conviction or certainty. Part of the achievement of effective communicators lies in their persuading their audiences that stepping-stones (warrants) do exist by which they can move from doubt to conviction.’
