On the show, All That, All That Tunes Into TV, on the spoof off of Star Trek, there is a slipup. The Evil Kruton says, I will use my telepathic powers to stop tour engines cold.
According to the Webster's Dictionary:
Telepathy: supposed communication between minds by some means other than the normal sensory channels
Telekinesis: the apparent initiation of movement in an object, as by a medium in spiritualism, without perceptible mechanical or other means
I still like my definitions better, but we all have our opinions:
Telepathy: You talk to people with your mind
Telekinesis: You move stuff with your mind
I got this from Psychic Jack on the discusion board. Thank him!
