Origin unknown.

First attested in the 1560s, the word meaning 'scaleless fish' is of uncertain origin: it was apparently brought to England, with a specimen, by John Hawkins. The word may derive from the Yucatec Maya xoc, or it may be an application of the "scoundrel" sense (which derives from the German Schurke ("scoundrel")) to the fish; no explanation is agreed upon.

  • Some species of shark must continually swim to avoid asphyxiation. Something along the same lines is true of the human brain. Deprived of all inflow of sensation, it must create its own (ala John Lilly's hallucination-inducing isolation tank experimentation). "Impressions" (q.v. Gurdjieff) are "food" for the brain, grist for the mental mill.
