The intuitions reported by mystics, poets, artists, ordinary people, even scientists, often go beyond the range of sensory perception. In the reductionist culture inspired by classical science, they are dismissed as mere delusion – classical empiricism claims that there is nothing in the mind that was not first in the eye. However, the classical tenet is not universally upheld. It is exceptional in the annals of history, and even in the context of contemporary cultures.In history intuitions were embedded in the conceptual framework through which a given culture interpreted the nature of reality. In indigenous societies shamans and medicine-men (and women) tuned themselves to spontaneous apprehension through rigorous initiation and training; they derived their mystical vision from them. In mythically oriented societies the world was seen as a cosmic realm of spirits, and in classical cultures it was believed to be governed by a panoply of unseen gods. The Abrahamic monotheistic religions recognized the intuitions of their prophets as conveying fundamental truths about God and the nature of His creation. Eastern cultures have always held that reality extends far beyond the domain of the senses.
