I have seen all I care to see and heard rather more. - Jack Vance

“We suspect that telepathy occurs instantaneously, if no faster—”

“In any event it seems that thought is a different stuff from our usual matter, that it obeys different laws, acts through a different medium, in a different dimension set, in short, works through a different space—implying a different universe.”
Tarbert frowned. “You’re getting a little carried away; you’re using the word ‘thought’ rather too easily. After all, what is ‘thought’? So far as we know, it’s a word to describe a complex of electrical and chemical processes in our brains, these more elaborate, but intrinsically no more mysterious, than the operation of a computer. With all the goodwill and predisposition in the world, I can’t see how ‘thought’ can work metaphysical miracles.”
