Epiphanies is a philosophical exploration of epiphanies, peak experiences, 'wow moments', or ecstasies as they are sometimes called. What are epiphanies, and why do so many people so frequently experience them? Are they just transient phenomena in our brains, or are they the revelations of objective value that they very often seem to be? What do they tell us about the world, and about ourselves? How, if at all, do epiphanies fit in with our moral systems and our theories of how to live? And how do epiphanic experiences fit in with the rest of our lives? These are Sophie Grace Chappell's questions in this ground-breaking new study of an area of inquiry that has always been right under our noses, but remains surprisingly under-explored in contemporary philosophy.
