Poseur in the context of Model (art)

Authenticity is a concept of personality in the fields of psychology, existential psychotherapy, existentialist philosophy, and aesthetics. In existentialism, authenticity is the degree to which a person's actions are congruent with their values and desires, despite external pressures to social conformity. The conscious self comes to terms with the condition of Geworfenheit, of having been thrown into an absurd world (without values and meaning) not of their own making, thereby encountering external forces and influences different from and other than the Self. Authenticity has emerged as a central concept in contemporary models of well-being and the good life, serving as a foundational principle in many leading psychological frameworks. A person’s lack of authenticity is considered bad faith in dealing with other people and with one's self; thus, authenticity is in the instruction of the Oracle of Delphi: “Know thyself.” Concerning authenticity in art, the philosophers Jean Paul Sartre and Theodor Adorno held opposing views and opinions about jazz, a genre of American music; Sartre said that jazz is authentic and Adorno said that jazz is inauthentic. Many musical subcultures require artistic authenticity, lest the community consider an artist to be a poseur for lacking authenticity (creative, musical, or personal); artistic authenticity is integral to many genres of music, including but not limited to genres of rock (such as punk rock and heavy metal), club music (such as house and techno), and hip-hop.

In the 18th century, Romantic philosophers recommended intuition, emotion, and a connection to Nature as the necessary counterbalances to the intellectualism of the Age of Enlightenment. In the 20th century, Anglo–American preoccupations with authenticity centered on the writings of existentialist philosophers whose native tongue is not English; therefore, the faithful, true, and accurate translation of the term existentialism was much debated, to which end the philosopher Walter Kaufmann assembled a canon of existentialist philosophers. Kaufmann's canon includes the Dane Søren Kierkegaard (1813–1855), the German Martin Heidegger (1889–1976), and the Frenchman Jean-Paul Sartre (1905–1980). For these existentialists, the conscious Self comes to terms with existence (being and living) in an absurd, materialist world featuring external forces, e.g. Geworfenheit (Thrown-ness), and intellectual influences different from and other than the Self.

Dame Edith Louisa Sitwell DBE (7 September 1887 – 9 December 1964) was a British poet and critic and the eldest of the three literary Sitwells. She reacted badly to her eccentric, unloving parents and lived much of her life with her governess. She never married but became passionately attached to Russian painter Pavel Tchelitchew, and her home was always open to London's poetic circle, to whom she was generous and helpful.

Sitwell published poetry continuously from 1913, some of it abstract and set to music. With her dramatic style and exotic costumes, she was sometimes labelled a poseur, but her work was praised for its solid technique and painstaking craftsmanship. She was a recipient of the Benson Medal of the Royal Society of Literature.
