Though it is obvious in all the species, humans tend to seek loftier meanings for their attention to the opposite sex. All of the senses, as well as common sense, fail because a biological drive causes the mistaken belief that the best looking, best smelling, best feeling, best tasting, and best sounding person has been found. Nothing would prevent the consummation of this discovery. Certainly not the simple task of signing a marriage certificate. The fact that there is a marriage certificate ready to be signed is indicative of another important reason behind marriages.
Marriage is one of the underpinnings of society.
It is important for all aspects of society, especially economic and legal. Convinced that marriages are vital to its very existence, societies have promoted marriages in almost every way possible. Most products and services are directed to the married couple, from hotel rooms and vacation packages to cars and houses. Parents and the clergy conspire with the tradespeople in glorifying weddings and the institution of marriage. In addition to the genetic and external influences, other causes for marriage involve false hopes and imagined needs.
