ItemSome theories of verisimilitudeWilson, Alan John (1948-) ( 1991)In this thesis it was decided to concentrate on the work of Sir Karl Popper and, in particular, his concept of verisimilitude. In this connection, a result in Harris' 1974 paper was considered in error. In chapter 1 Tich?'s demonstration that Popper's probabilistic definitions of verisimilitude are inadequate is discussed. The same is discussed with respect to Popper's logical definitions of verisimilitude in chapter 2. Such criticisms of Tich? cast doubt on the idea of verisimilitude or at least as it had been formulated by Popper. Chapter 3 considers the relationship between verisimilitude and language. Chapter 4 considers, in particular, the role weak theories can play, and the promise offered by a distance-from-the-truth function of Tich?. The results are summarised in the conclusion (chapter 5).
