"The atomic bomb had dwarfed the international issues to complete insignificance. When our minds wandered from the preoccupations of our immediate needs, we speculated upon the possibility of stopping the use of these frightful explosives before the world was utterly destroyed. For to us it seemed quite plain that these bombs and the still greater power of destruction of which they were the precursors might quite easily shatter every relationship and institution of mankind... war must end and that the only way to end war was to have but one government for mankind."

“In all the round world of Utopia there is no meat. There used to be. But now we cannot stand the thought of slaughter-houses. And, in a population that is all educated, and at about the same level of physical refinement, it is practically impossible to find anyone who will hew a dead ox or pig. We never settled the hygienic question of meat-eating at all. This other aspect decided us. I can still remember, as a boy, the rejoicings over the closing of the last slaughter-house.”

“Nothing could have been more obvious to the people of the early twentieth century than the rapidity with which war was becoming impossible. And as certainly they did not see it. They did not see it until the atomic bombs burst in their fumbling hands.”

First, this little planet and its winds and ways. And then all the laws of mind and matter that restrain him. Then the planets about him, and, at last, out across immensity to the stars.

“I had rather be called a journalist than an artist.”

“From 1789 to late in 1791 the French Revolution was an orderly process, and from the summer of 1794 the Republic was an orderly and victorious state. The Terror was not the work of the whole country, but of the town mob which owed its existence and its savagery to the misrule, and social injustice of the ancient regime...More lives were wasted by the British generals alone on the opening day of what is known as the Somme offensive of July, 1916 than in the whole French Revolution from start to finish.”
