- n. Synonyms Quack, Empiric, Mountebank, Charlatan. A quack is, by derivation, one who talks much without wisdom, and, specifically, talks of his own power to heal; hence, any ignorant pretender to medical knowledge or skill. Empiric is a more elevated term for one who goes by mere experience in the trial of remedies, and is without knowledge of the medical sciences or of the clinical observations and opinions of others; hence, an incompetent, self-confident practitioner. A mountebank is generally a quack, but may be a pretender in any line. Charlatan (literally ‘chatterer’) is primarily applied, not to a person belonging to any particular profession or occupation, but to a pretentious cheat of any sort.
