Destiny refers to a predetermined course of events. It may be conceived as a predetermined future, whether in general or of an individual. It is a concept based on the belief that there is a fixed natural order to the universe.

Different concepts of destiny and fate

Destiny may be envisaged as fore-ordained by the Divine (for example, the Protestant concept of predestination) or by human will (for example, the American concept of Manifest Destiny).

A sense of destiny in its oldest human sense is in the soldier's fatalistic image of the "bullet that has your name on it" or the moment when your number "comes up," or a romance that was "meant to be." The human sense that there must be a hidden purpose in the random lottery governs the selection of Theseus to be among the youths to be sacrificed to the Minotaur.

Destiny may be seen either as a fixed sequence of events that is inevitable and unchangeable, or that individuals choose their own destiny by choosing different paths throughout their life.

Destiny in literature and popular culture

Many Greek legends and tales teach the futility of trying to outmaneuver an inexorable fate that has been correctly predicted. This form of irony is important in Greek tragedy, as it is in Oedipus Rex and in the Duque de Rivas' play that Verdi transformed into La Forza del Destino ("The Force of Destiny") or Thornton Wilder's The Bridge of San Luis Rey, or in Macbeth's uncannily-derived knowledge of his own destiny, which in spite of all his actions does not preclude a horrible fate.

This aspect is succinctly told by W. Somerset Maugham from an Arab tale:

Death speaks: There was a merchant in Baghdad who sent his servant to market to buy provisions and in a little while the servant came back, white and trembling, and said, “Master, just now when I was in the market-place I was jostled by a woman in the crowd and when I turned I saw it was Death that jostled me. She looked at me and made a threatening gesture; now, lend me your horse, and I will ride away from this city and avoid my fate. I will go to Samarra and there Death will not find me.” The merchant lent him his horse, and the servant mounted it, and he dug his spurs in its flanks and as fast as the horse could gallop he went. Then the merchant went down to the marketplace and he saw me standing in the crowd and he came to me and said, “Why did you make a threatening gesture to my servant when you saw him this morning?” “That was not a threatening gesture,” I said, “it was only a start of surprise. I was astonished to see him in Baghdad, for I had an appointment with him tonight in Samarra.

Other notable examples include Thomas Hardy's Tess of the d'Urbervilles, in which Tess is destined to the miserable death that she is confronted with at the end of the novel; the popular short story "The Monkey's Paw" by W.W. Jacobs; and the M. Night Shyamalan film Signs. Destiny is a recurring theme in the literature of Hermann Hesse (1877-1962), including Siddharta (1922) and his magnum opus, Das Glasperlenspiel, also published as The Glass Bead Game (1943).The common theme of these works is a protagonist who cannot escape a destiny if their fate has been sealed, however hard they try. Destiny is also an important plot point in the hit TV shows Lost, Heroes and Supernatural, as well a common theme in the Roswell TV series.
