Its a tricky topic to approach from as skeptical of a wording as you chose.
Consider that the brain DOES cause a pencil to move. It sends the tiniest of electrical signals out down one tube, and a muscle does the work. How about telepathy? Consider the death-stare of a spouse reminding you that you should be moving pencils today without hishim or her lifting a finger (and you are also reminded you were supposed to move the pencil yesterday).
What is very tricky about this is your wording. Your wording suggests that the method of telekenesis/telepathy must be outside the realm of science. The effect has to be made by the mind (which is not fully defined by science or philosophers). However, history has shown that once we gain control over something, science models it and makes it part of itself. TK/TP will never occur by that definition, because every time it does, science moves the bar.
300 years ago, the telephone would have been considered telepathy.
