Exact truthmaking as solution for Lewis’s problem of permission
Hurne, F. van
MetadataShow full item record
I develop a method of permitting worlds, using an exact truthmaking approach instead of a world-based approach. My starting point is Lewis’s problem of permission, which I use to show world-based deontic logic is insufficient. As an alternative I provide an exact truthmaking approach for permission. As this approach makes it possible to determine if a permission is allowed, based on its truth-condition, I look at permitting not just states, but also worlds. I argue that worlds should be permitted when all the states it consists of are permitted.
