The subjective experience of "beauty" often involves the interpretation of some entity as being in balance and harmony with nature, which may lead to feelings of attraction and emotional well-being. "Beauty is in the eye of the beholder" is a common phrase that expresses this concept. In its most profound sense, beauty may engender a salient experience of positive reflection about the meaning of one's own existence. An "object of beauty" is anything that reveals or resonates with personal meaning.

The classical Greek adjective beautiful was καλλός. The Koine Greek word for beautiful was "ὡραῖος", an adjective etymologically coming from the word "ὥρα" meaning hour. In Koine Greek, beauty was thus associated with "being of one's hour". A ripe fruit (of its time) was considered beautiful, whereas a young woman trying to appear older or an older woman trying to appear younger would not be considered beautiful. ὡραῖος in Attic Greek had many meanings, including youthful and ripe old age.

History of beauty

Symmetry is also important because it suggests the absence of genetic or acquired defects. Although style and fashion vary widely, cross-cultural research has found a variety of commonalities in people's perception of beauty. Large eyes and a clear complexion, for example, are considered beautiful in both men and women in all cultures. Neonatal features are inherently attractive and youthfulness in general is associated with beauty.

There is evidence that a preference for beautiful faces emerges early in child development, and that the standards of attractiveness are similar across different genders and cultures.

The foundations laid by Greek and Roman artists have also supplied the standard for male beauty in western civilization. The ideal Roman was defined as tall, muscular, long-legged, with a full head of thick hair, a high and wide forehead – a sign of intelligence – wide-set eyes, a strong browline, a strong perfect nose and profile, a smaller mouth, and a strong jaw line. This combination of factors would, as it does today, produce an impressive "grand" look of handsome masculinity.

Beauty ideals may contribute to racial oppression. For example, a prevailing idea in American culture has been that black features are less attractive or desirable than white features. The idea that blackness was ugly was highly damaging to the psyche of African Americans, manifesting itself as internalized racism. The black is beautiful cultural movement sought to dispel this notion. Conversely, beauty ideals may also promote racial unity. Mixed race children are often perceived to be more attractive than their parents because their genetic diversity protects them from the inherited errors of their individual parents.
