Spontaneous freedom—the freedom of unscripted activity that “free spirits” enjoy—is central to ordinary talk about “freedom.” But it is absent from many contemporary moral philosophers’ accounts of freedom. I provide a phenomenological study of spontaneous freedom and argue that to experience spontaneous freedom is to experience one’s activity as not settled in advance by anyone else’s conscious, reflective decisions or even by one’s own preexisting, consciously endorsed plans. I then argue that the phenomenology of spontaneous freedom lends support to compatibilists in the free will debate. [Draft of October 30, 2018]
