It would seem that only human beings try to do things by halves, and that this half-measure is a luxury of illusion. As Philip K. Dick once inferred, privacy may be a valid concept only to “idiots” who have learned to shut down their communication centers, to the extent that all “telepathic” interface occurs only at an unconscious level. In other words, even while we are constantly swapping all our vital data, we don’t actually know it. —Jasun Horsley, Mirror Neurons & the Arcane Art of Writing
