What is ESP?
ESP stands for extrasensory perception, or an act of learning something about the world that has not been conveyed to us in ordinary ways. It appears to arrive in spite of ordinary barriers of space and time. If the act of knowing involves the physical world only, then it is spoken of as clairvoyance; if it involves the thoughts or feelings of another person, it is often called telepathy; and if it involves something that has not yet happened but occurs in the future, it is called precognition.
