Physiognomy
Summary
Physiognomy (from the Greek φύσις, , meaning "nature", and , meaning "judge" or "interpreter") is the practice of assessing a person's character or personality from their 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).
Physiognomy as a practice meets the contemporary definition of pseudoscience and it is so regarded among academic circles because of its unsupported claims; popular belief in the practice of physiognomy is nonetheless still widespread and modern advances in artificial intelligence have sparked renewed interest in the field of study. The practice was well-accepted by ancient Greek philosophers, but fell into disrepute in the Middle Ages while practised by vagabonds and mountebanks. It revived and was popularised by Johann Kaspar Lavater, before falling from favor in the late 19th century. Physiognomy in the 19th century is particularly noted as a basis for scientific racism. Physiognomy as it is understood today is a subject of renewed scientific interest, especially as it relates to machine learning and facial recognition technology. The main interest for scientists today are the risks, including privacy concerns, of physiognomy in the context of facial recognition algorithms.
Physiognomy is sometimes referred to as 'anthroposcopy', a term originating in the 19th century.
Notions of the relationship between an individual's outward appearance and inner character date back to antiquity, and occasionally appear in early Greek poetry. Siddhars from ancient India defined as identifying personal characteristics with body features. Chinese physiognomy or Chinese face reading () dates back to at least the Spring and Autumn period.
Early indications of a developed physiognomic theory appear in 5th century BC Athens, with the works of Zopyrus (who was featured in a dialogue by Phaedo of Elis), an expert in the art.
