"The economic life of the human race had for some time been based on coal, but latterly oil had been found a far more convenient source of power; and as the oil store of the planet was much smaller than its coal store, and the expenditure of oil had of course been wholly uncontrolled and wasteful, a shortage was already being felt. Thus the national ownership of the remaining oil fields had become a main factor in politics and a fertile source of wars."

“Nothing but man was really cruel, vindictive, except perhaps the loathly cat.”

“Individuals of the earlier species had suffered from an almost insurmountable spiritual isolation from one another. Not even lovers, and scarcely even the geniuses with special insight into personality, ever had anything like accurate vision of one another.”

“In some minds the defence of the human spirit was sincerely identified with the defence of a particular nation, conceived as the home of all enlightenment.”

“You can imagine that it is not easy to describe this modern vision of the nature of things in any manner intelligible to those who have not our advantages. There is much in this vision which will remind you of your mystics; yet between them and us there is far more difference than similarity, in respect both of the matter and the manner of our thought. For while they are confident that the cosmos is perfect, we are sure only that it is very beautiful. While they pass to their conclusion without the aid of intellect, we have used that staff every step of the way. Thus, even when in respect of conclusions we agree with your mystics rather than your plodding intellectuals, in respect of method we applaud most your intellectuals; for they scorned to deceive themselves with comfortable fantasies.”

“Dear beautiful one, I praise the stars for the song's end. Farewell!”

“he thought is somewhat repugnant to us that we should slowly sink into barbarism, into the sub-human, into blind and whimpering agony, that the last of Man should be a whine. This may well happen, but even by such a prospect we are not seriously dismayed. If it does occur, it will doubtless seem intolerable to our degraded spirits. But today, we are fully possessed of ourselves. o the spirit that has drunk deeply of the grave beauty of the cosmos, even the ultimate horror is acceptable.”
