William Stanley Jevons,
Political economy
“ Now, when trade is left free it gives rise to division of labour, not only between town and town, county and county, but between the most distant nations of the earth. Thus is created what may be called the territorial division of labour. Commerce between nation and nation is not only one of the best means of increasing wealth and saving labour, but it brings us nearer to the time when all nations will live in harmony, as if they were but one nation. ”
