(d) When a courtezan at her own expense, and without any results in the shape of gain, has connection with a great man, or an avaricious minister for the sake of diverting some misfortune, or removing some cause that may be threatening the destruction of a great gain, this loss is said to be a loss of wealth attended by gains of the future good which it may bring about.
