Unlike the older forms of occultism, such as magic and astrology, organized occultism is a modern phenomenon. Few of the various organized occult movements have existed for more than 150 years; some were formed as a belated countermovement to the Enlightenment, when people began to follow rational schools of thought. Today’s occult views are based on the idea that there are events within nature, as well as within one’s spiritual life, which seem mysterious and cannot be explained by science. Examples include extrasensory perceptions such as telepathy and telekinesis, and haunted places or people. Believers maintain that these phenomena stem from unknown powers that can often be accessed only by some people with special abilities.
