Eccentricity (behavior)

Eccentricity (also called quirkiness) is an unusual or odd behavior on the part of an individual. This behavior would typically be perceived as unusual or unnecessary, without being demonstrably maladaptive. Eccentricity is contrasted with normal behavior, the nearly universal means by which individuals in society solve given problems and pursue certain priorities in everyday life. People who consistently display benignly eccentric behavior are labeled as "eccentrics". From Medieval Latin eccentricus, derived from Greek ekkentros, "out of the center", from ek-, ex- "out of" + kentron, "center". Eccentric first appeared in English essays as a neologism in 1551 as an astronomical term meaning "a circle in which the earth, sun, etc. deviates from its center." Five years later, in 1556, an adjective form of the word was used. In 1685, the definition evolved from the literal to the figurative, and eccentric is noted to have begun being used to describe unconventional or odd behavior. A noun form of the word – a person who possesses and exhibits these unconventional or odd qualities and behaviors – appeared by 1832. Eccentricity is often associated with genius, intellectual giftedness, or creativity. People may perceive the individual's eccentric behavior as the outward expression of their unique intelligence or creative impulse. In this vein, the eccentric's habits are incomprehensible not because they are illogical or the result of madness, but because they stem from a mind so original that it cannot be conformed to societal norms. English utilitarian thinker John Stuart Mill (1806–1873) wrote that "the amount of eccentricity in a society has generally been proportional to the amount of genius, mental vigour, and moral courage which it contained", and mourned a lack of eccentricity as "the chief danger of the time". Edith Sitwell (1887–1964) wrote that eccentricity is "often a kind of innocent pride", also saying that geniuses and aristocrats are called eccentrics because "they are entirely unafraid of and uninfluenced by the opinions and vagaries of the crowd".
