ABSTRACT
In this chapter I shall look at two potential obstacles to the libertarian’s view that, in order for us to be free and responsible agents, our future must be physically open – a “garden of forking paths”, as it has been described. e rst obstacle is an argument by Harry Frankfurt designed to refute what he terms the “principle of alternate possibilities”. e second obstacle is the special theory of relativity, which appears to imply that the future simply cannot be a garden of forking paths.
