 To see this distinction between truthlikeness and probability clearly, and to articulate it, was one of Popper’s most significant contributions, not only to the debate about truthlikeness, but to philosophy of science and logic in general. However, his deep antagonism to probability, combined with his love of boldness, was both a blessing and a curse. The blessing: it led him to produce not only the first interesting and important account of truthlikeness, but to initiate an approach to the problem in terms of content. The curse: content alone, as Popper envisaged it, is insufficient to characterize truthlikeness.
