Selected letters to, or from, Arthur Norman Prior, on metaphysics edited and introduced by David Jakobsen. Prior's correspondence, with Karl Popper, J.J.C Smart, Georg Henrik von Wright and his wife Mary Prior contributes to a fine-grained perspective on the importance of Arthur Prior's work for the return of metaphysics in analytic philosophy.

David Jakobsen holds a Ph.D from Aalborg University on the history of tense-logic.
