“Since the political struggles of France, Italy, Spain, and Greece, the word patriotism has been employed, throughout continental Europe, to express a love of the public good; a preference for the interests of the many to those of the few; a desire for the emancipation of the human race from the thrall of despotism, religious and of the human race from the thrall of despotism, religious and civil; in short, patriotism there is used rather to express the interest felt in the human race in general, than that felt for any country, or inhabitants of a country, in particular. And patriot, in like manner, is employed to signify a lover of human liberty and human improvement, rather than a mere lover of the country in which he lives, or the tribe to which he belongs. Used in this sense, patriotism is a virtue, and a patriot a virtuous man.”

In "Wages are Going Lower!" (1951), William Joseph Baxter wrote, "One might almost say that the human race seems to have improved everything except people."

Context: Because boys lack a biological marker like menstruation, to be man is to be not female. Contemporary feminism called this "misogyny," but it was wrong. Masculine identity is embattled and fragile. In the absence of opportunity for heroic physical action, as in the modern office world, women's goodwill is crucial for preserving the male ego, which requires, alas, daily maintenance. It is in the best interests of the human race, and of women themselves, for men to be strong.

Kalki : or The Future of Civilization (1929)
Context: The East and the West are not so sharply divided as the alarmists would make us believe. The products of spirit and intelligence, the positive sciences, the engineering techniques, the governmental forms, the legal regulations, the administrative arrangements, and the economic institutions are binding together peoples of varied cultures and bringing them into closer reciprocal contact. The world today is tending to function as one organism.
The outer uniformity has not, however, resulted in an inner unity of mind and spirit. The new nearness into which we are drawn has not meant increasing happiness and diminishing friction, since we are not mentally and spiritually prepared for the meeting. Maxim Gorky relates how, after addressing a peasant audience on the subject of science and the marvels of technical inventions, he was criticized by a peasant spokesman in the following words : "Yes, we are taught to fly in the air like birds, and to swim in the water like the fishes, but how to live on the earth we do not know."
Among the races, religions, and nations which live side by side on the small globe, there is not that sense of fellowship necessary for good life. They rather feel themselves to be antagonistic forces. Though humanity has assumed a uniform outer body, it is still without a single animating spirit. The world is not of one mind. … The provincial cultures of the past and the present have not always been loyal to the true interests of the human race. They stood for racial, religious, and political monopolies, for the supremacy of men over women and of the rich over the poor. Before we can build a stable civilization worthy of humanity as a whole, it is necessary that each historical civilization should become conscious of its limitations and it's unworthiness to become the ideal civilization of the world.

Forewords and Afterwords (1973)
Context: In most poetic expressions of patriotism, it is impossible to distinguish what is one of the greatest human virtues from the worst human vice, collective egotism.
The virtue of patriotism has been extolled most loudly and publicly by nations that are in the process of conquering others, by the Roman, for example, in the first century B. C., the French in the 1790s, the English in the nineteenth century, and the Germans in the first half of the twentieth. To such people, love of one's country involves denying the right of others, of the Gauls, the Italians, the Indians, the Poles, to love theirs.

1950s, What Desires Are Politically Important? (1950)
Context: Killing an enemy in a modern war is a very expensive operation... It is obvious that modern war is not good business from a financial point of view. Although we won both the world wars, we should now be much richer if they had not occured. If men were actuated by self-interest, which they are not – except in the case of a few saints – the whole human race would cooperate. There would be no more wars, no more armies, no more navies, no more atom bombs. There would not be armies of propagandists employed in poisoning the minds of Nation A against Nation B, and reciprocally of Nation B against Nation A. There would not be armies of officials at frontiers to prevent the entry of foreign books and foreign ideas, however excellent in themselves. There would not be customs barriers to ensure the existence of many small enterprises where one big enterprise would be more economic. All this would happen very quickly if men desired their own happiness as ardently as they desired the misery of their neighbors. But, you will tell me, what is the use of these utopian dreams? Moralists will see to it that we do not become wholly selfish, and until we do the millennium will be impossible.
