“Differences between Catholic and Protestant countries did not incite rivalries between European states, or cause the growing sense of national identity and, sometimes, isolationism that was developing among the countries of Europe. These were happening anyway, for a complex variety of political and economic reasons. But religious differences did, at times, contribute to them—for example in Spain, where the inward-looking institutions of the Counter-Reformation seemed aimed at creating a nation of soldiers and ecclesiastics in great contrast to the outgoing, trade-based, profit-minded society of the Calvinist Netherlands. These generalizations hide many local variations—there were busy Spanish merchants, and contemplative, spiritual, people in many Protestant lands. But travelers across Europe remarked on the increasingly striking differences between nations.”

“Europe, it is true, is a geographical and, within certain limits, an historical cultural conception. But the idea of Europe as an economic unit contradicts capitalist development in two ways. First of all there exist within Europe among the capitalist States – and will so long as these exist – the most violent struggles of competition and antagonisms, and secondly the European States can no longer get along economically without the non-European countries. ... At the present stage of development of the world market and of world economy, the conception of Europe as an isolated economic unit is a sterile concoction of the brain. ...And if the idea of a European union in the economic sense has long been outstripped, this is no less the case in the political sense.....Only were one suddenly to lose sight of all these happenings and manoeuvres, and to transfer oneself back to the blissful times of the European concert of powers, could one say, for instance, that for forty years we have had uninterrupted peace. This conception, which considers only events on the European continent, does not notice that the very reason why we have had no war in Europe for decades is the fact that international antagonisms have grown infinitely beyond the narrow confines of the European continent, and that European problems and interests are now fought out on the world seas and in the by-corners of Europe.”

“National differences and antagonisms between peoples are daily more and more vanishing, owing to the development of the bourgeoisie, to freedom of commerce, to the world-market, to uniformity in the mode of production and in the conditions of life corresponding thereto.The supremacy of the proletariat will cause them to vanish still faster. United action, of the leading civilized countries at least, is one of the first conditions for the emancipation of the proletariat.In proportion as the exploitation of one individual by another is put an end to, the exploitation of one nation by another will also be put an end to. In proportion as the antagonism between classes within the nation vanishes, the hostility of one nation to another will come to an end.”

“People.. were poor not because they were stupid or lazy. They worked all day long, doing complex physical tasks. They were poor because the financial institution in the country did not help them widen their economic base.”

“The relation between the white and colored people of this country is the great, paramount, imperative, and all-commanding question for this age and nation to solve.”

“...[at the Constitutional Convention] the States were divided into different interests not by their difference of size, but principally from their having or not having slaves. It did not lie between the large and small States: it lay between the Northern and Southern.”
