As to the patriotic prejudice, this is also due to absolute ignorance, for the surface of the earth is one native land. Every one can live in any spot on the terrestrial globe. Therefore all the world is man’s birthplace. These boundaries and outlets have been devised by man. In the creation, such boundaries and outlets were not assigned. Europe is one continent, Asia is one continent, Africa is one continent, Australia is one continent, but some of the souls, from personal motives and selfish interests, have divided each one of these continents and considered a certain part as their own country. God has set up no frontier between France and Germany; they are continuous. Yea, in the first centuries, selfish souls, for the promotion of their own interests, have assigned boundaries and outlets and have, day by day, attached more importance to these, until this led to intense enmity, bloodshed and rapacity in subsequent centuries. In the same way this will continue indefinitely, and if this conception of patriotism remains limited within a certain circle, it will be the primary cause of the world’s destruction. No wise and just person will acknowledge these imaginary distinctions. Every limited area which we call our native country we regard as our mother-land, whereas the terrestrial globe is the mother-land of all, and not any restricted area. In short, for a few days we live on this earth and eventually we are buried in it, it is our eternal tomb. Is it worth while that we should engage in bloodshed and tear one another to pieces for this eternal tomb? Nay, far from it, neither is God pleased with such conduct nor would any sane man approve of it.
