Sincerity is the virtue of one who communicates and acts in accordance with the entirety of their feelings, beliefs, thoughts, and desires in a manner that is honest and genuine.
Etymology
The Oxford English Dictionary and most scholars state that sincerity from sincere is derived from the Latinsincerus meaning clean, pure, sound. Sincerus may have once meant "one growth", from sin- and crescere. Crescere is cognate with "Ceres," the goddess of grain, as in "cereal." According to the American Heritage Dictionary, the Latin word sincerus is derived from the Indo-European root*sm̥kēros, itself derived from the zero-grade of *sem and the suffixed, lengthened e-grade of *ker, generating the underlying meaning of one growth, hence pure, clean.
Controversy
An often repeated folk etymology proposes that sincere is derived from the Latin sine = without, cera = wax. According to one popular explanation, dishonest sculptors in Rome or Greece would cover flaws in their work with wax to deceive the viewer; therefore, a sculpture "without wax" would mean honesty in its perfection. In its early days the word could refer to the immaterial and material. "One spoke of sincere wine...simply to mean that it had not been adulterated, or, as was once said, sophisticated." Another explanation is that this etymology "is derived from a Greeks-bearing-gifts story of deceit and betrayal. For the feat of victory, the Romans demanded the handing over of obligatory tributes. Following bad advice, the Greeks resorted to some faux-marble statues made of wax, which they offered as tribute. These promptly melted in the warm Greek sun." The Oxford English Dictionary states, however, that "there is no probability in the old explanation from sine cera 'without wax'". The popularity of the without wax etymology is reflected in its use as a minor subplot in Dan Brown's 1998 thriller novelDigital Fortress, though Brown attributes it to the Spanish language, not Latin. Reference to the same etymology, this time attributed to Latin, later appears in his 2009 novel, The Lost Symbol.
First discussed by Aristotle in his , it resurfaced to become an ideal in Europe and North America in the 17th century; and it gained considerable momentum during the Romantic movement, when sincerity was first celebrated as an artistic and social ideal. Indeed, in middle to late nineteenth century America, sincerity was an idea reflected in mannerisms, hairstyles, women's dress, and the literature of the time. Literary criticLionel Trilling dealt with the subject of sincerity, its roots, its evolution, its moral quotient, and its relationship to authenticity in a series of lectures published under the title Sincerity and Authenticity.
Aristotle's views
According to Aristotle "truthfulness or sincerity is a desirable mean state between the deficiency of irony or self-deprecation and the excess of boastfulness."
See Beyond the Western culture, sincerity is notably developed as a virtue in Confucian societies. The concept of chéng — as expounded in two of the Confucian classics, the Da Xue and the Zhong Yong — is generally translated as sincerity. As in the West, the term implies a congruence of avowal and inner feeling, but inner feeling is in turn ideally responsive to ritual propriety and social hierarchy. Specifically, Confucian's Analects contains the following statement in Chapter I: "Hold faithfulness and sincerity as first principles. Then no friends would not be like yourself. If you make a mistake, do not be afraid to correct it." Thus, even today, a powerful leader will praise leaders of other realms as "sincere" to the extent that they know their place in the sense of fulfilling a role in the drama of life. In Japanese the character for chéng may be pronounced makoto, and carries still more strongly the sense of loyal avowal and belief.
