The term teleologic hallucination is indebted to the Greek words teleios (to have reached its fulfillment), and logos (word, teaching). It was coined by the Swiss psychiatrist Eugen Bleuler (18571939) to denote a hallucination that involves a warning or advice designed to prevent the subject from carrying out a potentially harmful act.
