“In your day if all the wealth of the world had been equally divided among its inhabitants there would hardly have been enough for each person, to maintain him one year. The people lived from hand to mouth, and if the earth had failed to bring forth her bounty in crops for one year, half the population would have perished. Now if sun and rain should fail to mature the crops, the giant laboratories of artificial food can soon supply the deficiency. The tendency of the times is to depend less and less on the cultivation of the natural foods that are liable to the chances of unfavorable wind and weather, and to rely on the artificial products the creation of which is a matter of scientific certainty and accuracy. “Let us now put ourselves forward again; this time one hundred millenniums, and look into the past as we have done before. We shall see that before the middle of the first millennium the principal articles of food are artificial productions identically like the natural foods formerly used such as milk, flour, meat, butter, fruits, vegetables etc. In addition to these many other foods were invented similar and equivalent to these natural productions. Later on the artificial products came more and more to consist of the proximate principles and condensed forms of food, fats, oils, sugar, and starch, gum, gluten, albumen, fibrin, casein, gelatine etc., directly from minerals, especially coal, or from cheap vegetation such as weeds that in your day were destroyed as worthless, sea weed etc., also from sea animals. Nothing came amiss, chemistry could produce rich and nourishing food from what in your day were the most unpromising materials, and at a merely nominal cost too, because power was furnished by the sun as I have explained to you. The constant tendency of chemical discovery was toward the production of foods in their purity, unmixed with the bulky residuum that goes with natural foods and that in the process of assimilation has to be rejected. As the foods thus became more condensed and pure a few spoons full became the daily food of a man, the pleasures of the table became less keen and protracted and gradually fell out of fashion. Other methods of recreation were more cultivated, such as music, oratory, the lyceum, theater, scientific lectures and experiments, games, etc. In many other respects the habits and fashions of life changed during the first millennium. The practice of walking was almost discontinued; flying machines having come into universal use. They reached perfection and were so inexpensive to operate, that they became a part of the equipment of everybody. Gentlemen went to their business, ladies went shopping, children went to school, with their flyers, as they formerly used to do to a less universal extent, with their bicycles.
