  • The distinction between sanity and insanity is narrower than a razor’s edge, sharper than a hound’s tooth, more agile than a mule deer. It is more elusive than the merest phantom. Perhaps it does not even exist; perhaps it is a phantom.

    Philip K. Dick (2011). “The VALIS Trilogy”, p.56, Houghton Mifflin Harcourt
