 | | Extra-sensory perception, or ESP, is the name given to any ability to acquire information by means other than the five canonical senses (taste, sight, touch, smell, and hearing), or any other sense well-known to science (balance, proprioception, etc). |
 | | The notion of extra-sensory perception is a very old one, and in many ancient cultures it was taken for granted that certain people had such powers of perception, be it second sight, or the power to communicate with deities, ancestors, or spirits. |
 | | Among the difficulties having to do with proving the existence or non-existence of extra-sensory perception are that, if ESP exists, it may have a subtle rather than an overt effect, and that the ability to perceive may be altered by the nature of the event being perceived. |
