What does science have to say about ghosts, ESP, and astrology?
Rigorous and well controlled scientific investigations1 have examined these topics and have found no evidence supporting their usual interpretations as natural phenomena (i.e., ghosts as apparitions of the dead, ESP as the ability to read minds, and astrology as the influence of celestial bodies on human personalities and affairs) although, of course, different people interpret these topics in different ways. Science can investigate such phenomena and explanations only if they are thought to be part of the natural world.
