 First, philosophers have long claimed that we have introspective evidence of freedom in our experience of action, or perhaps of consciously attended or deliberated action. Augustine and Scotus, discussed earlier, are two examples among many. In recent years, philosophers have been more carefully scrutinizing the experience of agency and a debate has emerged concerning its contents, and in particular whether it supports an indeterministic theory of human free action. For discussion, see Deery et al. (2013), Guillon (2014), Horgan (2015), and Bayne (2017).
