Physiognomies

Physiognomy (from the Gk. meaning "nature" and meaning "judge" or "interpreter") is the assessment of character or personality from a person's outer appearance, especially the face. 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 from time to time. The practice was well accepted by the ancient Greek philosophers, but fell into disrepute in the Middle Ages when practised by vagabonds and mountebanks. It was then revived and popularised by Johann Kaspar Lavater before falling from favour again in the late 19th century. Physiognomy as understood in the past meets the contemporary definition of a pseudoscience.

Popular in the 19th century, it has been used as a basis for scientific racism, along with Physical anthropology.

No clear evidence indicates physiognomy works—but the rise of artificial intelligence and machine learning for facial recognition has brought a revival of interest, and some studies that suggest that facial appearances do "contain a kernel of truth" about a person's personality.

Physiognomy is also sometimes referred to as anthroposcopy, though the expression was more common in the 19th century when the word originated.

Notions of the relationship between an individual's outward appearance and inner character are historically ancient, and occasionally appear in early Greek poetry. Siddhars from ancient India are also known to have defined samudrika lakshanam that identifies personal characteristics with body features. Chinese physiognomy or face reading (mianxiang) reaches back at least to the Northern Song period. The first indications of a developed physiognomic theory appear in fifth century BC Athens, with the works of Zopyrus (who was featured in a dialogue by Phaedo of Elis), who was said to be an expert in the art. By the fourth century BC, the philosopher Aristotle made frequent reference to theory and literature concerning the relationship of appearance to character. Aristotle was apparently receptive to such an idea, as evidenced by a passage in his Prior Analytics:
