Beauty is a characteristic of an animal, idea, object, person or place that provides a perceptual experience of pleasure or satisfaction. Beauty is studied as part of aesthetics, culture, social psychology, philosophy and sociology. An "ideal beauty" is an entity which is admired, or possesses features widely attributed to beauty in a particular culture, for perfection.
A practitioner is someone who is qualified to or registered to practice a particular occupation, profession, or religion. Practitioners who are in a particular area may be referred to as a specialist or advanced practitioner. The medical and social care professions use these titles to distinguish the level of qualifications, competency, and training a practitioner undertakes.
Beauty is truth, truth beauty, — that is all
Ye know on earth, and all ye need to know.
John Keats, Poems (1820), "Ode on a Grecian Urn", last lines.
