Charles Babbage on Society

"The first application of this principle must have been made in a very early stage of society; for it must soon have been apparent that more comforts and conveniences could be acquired by one man restricting his occupation to the art of making bows, another to that of building houses, a third boats, and so on. This division of labor Into trades was not, however, the result of an opinion that the general riches of the community would be increased by such an arrangement: but it must have arisen from the circumstances, of each individual so employed discovering that he himself could thus make a greater profit of his labour than by pursuing more varied occupations."
