Mammals, birds, reptiles, fish, and probably most or all invertebrates can feel (something, sometimes) — but not rhododendrons or Rhizobium radiobacte<\/em>r or Rutstroemia firma<\/em>… or any of today’s robots. <\/p>\n\n\n\n

There is no more absolute difference than that between a sentient entity and an insentient one, even if both are living organisms.<\/p>\n\n\n\n

(Sedatives can dim feeling, general anesthesia can temporarily turn it off, and death or brain-death can turn it off permanently, but the capacity or incapacity to feel anything at all, ever, is all-or-none.)<\/p>\n\n\n\n
