The publication, twenty-five years ago, of the by now classical textbook "Proofs and Types" (Girard, Lafont, Taylor 1989) marked the consolidation of the tradition arising from the Curry-Howard connection between logic (natural deduction) and theoretical computer science (typed lambda calculi).
Many developments and extensions of this connection have been investigated in the last years (by means of linear logic, abstract machines, geometry of interaction, ludics, just to name some directions of research), providing at the same time several theoretical challenges to the original Curry-Howard paradigm.
Then, some important questions related to logic and philosophy naturally arise, e.g. the following two questions:
1) What has the correspondence between logic and computation evolved into during these years?
2) What was the impact of this tradition on the philosophical investigations on the foundations of logic and mathematics?
