A human being is primarily a bag for putting food into; the other functions and faculties may be more godlike, but in point of time they come afterwards. A man dies and is buried, and all his words and actions are forgotten, but the food he has eaten lives after him in the sound or rotten bones of his children. I think it could be plausibly argued that changes of diet are more important than changes of dynasty or even of religion. The Great War, for instance, could never have happened if tinned food had not been invented. And the history of the past four hundred years in England would have been immensely different if it had not been for the introduction of root-crops and various other vegetables at the end of the Middle Ages, and a little later the introduction of non-alcoholic drinks (tea, coffee, cocoa) and also of distilled liquors to which the beer-drinking English were not accustomed. Yet it is curious how seldom the all-importance of food is recognized. You see statues everywhere to politicians, poets, bishops, but none to cooks or bacon-curers or market-gardeners.
