Food must be bought or produced, and this involves cooperation, competition, self-denial, thrift, science, finance, invention. It involves ethics, because though you are hungry you must not steal food or give improper value for it. Moreover, though you are hungry, you have developed tastes, manners, etc., and you cannot, must not eat this or that (through religion); you mast eat with certain implements), and would rather die than violate the established standards in such matters.[1] Thus to the simple act of eating, to the satisfaction of a primitive desire set up by a primitive need, there are any number of obstacles set up by the complexities of our social existence. The sanction of these obstacles, their power to influence us, rests in other desires and purposes arising out of other "needs" of our nature. What are those needs? They are inherent in what has been called the social instincts, in that side of our nature which makes us yearn for approval and swings us into conformity with a group. The group organizes the activities of its individuals just as an individual organizes his activities. The evolutionists explain this group feeling as part of the equipment necessary for survival. Perhaps this is an adequate account of the situation, but the strength of the social instincts almost lead one to a more mystical explanation, a sort of acceptance of the group as the unit and the individual as an incomplete fragment. [1] The Sepoy Rebellion had its roots in a food taboo, and Mussulman, Hebrew and Roman Catholic place a religious value on diet. Most of the complexities of existence are of our own creation. What is true of hunger is true of thirst and fatigue. Desires in these directions have to accommodate themselves, in greater or lesser degrees, to the complexities in which our social nature and customs have involved us. It is true that desires upon which the actual survival of the individual depend will finally break through taboo and restriction if completely balked. That is, very few people will actually starve to death, die of thirst or keep awake indefinitely, despite any convention or taboo. Nevertheless there are people who will resist these fundamental desires, as in the case of MacSwiney, the Irish republican, and as in the case of martyrs recorded in the history of all peoples. It may be that in some of these we are dealing with a powerful inhibition of appetite of the kind seen in anhedonia.
