This confused thinking and failure to appreciate the difference between "part of" and "belonging to" has delayed Pan-Angle progress. It led to the disrupting American Revolution, to the Canadian Rebellion of 1837, and to frictions less in importance only because they were more promptly remedied. It has been an unnecessary difficulty in the way of all schemes proposed for closer Britannic union. Are the self-governing colonies to be united to each other and to the Mother Country?--or to these and to the dependencies besides? The word empire is variously used, and the thought underlying it sometimes vague. To some Britannic writers it refers inclusively to every spot over which the British flag flies, classing all colours and conditions of men in one category.[15-1] Others restrict its use to self-governing areas and peoples.[15-2] To still other minds it connotes lack of self-government, and is applicable only to the dependencies.[15-3] The "imperial parliaments" conjured {16} up by these three definitions are vastly dissimilar. And the New Zealander, for instance, would like to know, before he becomes a party to one, whether he is going to help rule India, or to sit in joint deliberation with its representatives.[16-1] The British Isles and the countries that have developed from British colonies form numerous and interrelated political groups. The largest, and now most important areas from a racial point of view, are New Zealand, Australia, South Africa, Newfoundland, Canada, the British Isles, and the United States of America. In this discussion these seven nations are considered as representing their race. Their peoples are known respectively as New Zealanders, Australians, South Africans, Newfoundlanders, Canadians, Britishers, and Americans. These seven nations hold in actual or allied control lands amounting to sixteen million square miles, with a population of five hundred and thirty-five million people,[16-2] or thirty and thirty-three per cent. respectively of the entire surface, and the entire {17} population of the world. Rome at her greatest dominated a population of one hundred and twenty millions.[17-1] In these seven nations more than one hundred and forty-one millions are white people,[17-2] nearly all speaking the same language, and all enjoying individual liberty of substantial equality. They govern themselves and they govern other peoples of other languages, colours, and ideals, to a total of nearly four times the entire Roman Empire. To the English-speaking whites these subject-peoples owe their privileges, such as they are. Success or failure in governing themselves and others depends for these whites on their ability so to control themselves that no foreign powers can interfere with this world-wide domination.
