To some, the possibility that great religious figures might have been influenced by epileptic experiences negates the reality of the religious beliefs that resulted from them. Yet to others, the resulting revelations are “no less expressive of truth than Dostoevsky’s novels or Van Gogh’s paintings.” Evidence does exist of an organic basis for instinctive reactions that give rise to beliefs about a moral order resulting in a religious experience. However, some would argue that this is merely the way by which a spiritual God interacts with us mortal beings.
