"Today we should welcome, and even study, every serious attempt to envisage the future of our race; not merely in order to grasp the very diverse and often tragic possibilities that confront us, but also that we may familiarize ourselves with the certainty that many of our most cherished ideals would seem puerile to more developed minds. To romance of the far future, then, is to attempt to see the human race in its cosmic setting, and to mould our hearts to entertain new values."

“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.”
