I'm watching a 25 minute video of Strawson and Evans talking about truth, made for the Open University in 1973. They debate the merits of understanding truth in deflationary terms. Evans defends the proposal, Strawson criticizes it. Unsurprisingly, the video ends without resolving the issue. Strawson is about to respond to a proposal that Evans makes for delimiting the range of sentences for which the question of truth can arise in terms of what can be believed, when he looks up at the moderator and says that he won't be able to show why his approach is correct because they don't have enough time.
