Physiognomy Physiognomy Physiognomy (from the Greek φύσις "physis" meaning "nature" and "gnomon" meaning "judge" or "interpreter") is a practice of assessing a person's character or personality from their outer appearance—especially the face. It is often linked to racial and sexual stereotyping. The term can also refer to the general appearance of a person, object, or terrain without reference to its implied characteristics—as in the physiognomy of an individual plant (see plant life-form) or of a plant community (see vegetation). Credence of such study has varied. The practice was well accepted by the ancient Greek philosophers, but fell into disrepute in the
Physiognomy structures of nature such as a plant's roots, stem, and flower, were indicative keys (or 'signatures') to their medicinal potentials. Lavater received mixed reactions from scientists, with some accepting his research and others criticizing it. For example, the harshest critic was scientist Georg Christoph Lichtenberg, who said pathognomy, discovering the character by observing the behaviour, was more effective. Writer Hannah More complained to Horace Walpole, "In vain do we boast ... that philosophy had broken down all the strongholds of prejudice, ignorance, and superstition; and yet, at this very time ... Lavater's physiognomy books sell at fifteen guineas a set."
