“The study of Nature makes a man at last as remorseless as Nature.”

“It is a law of nature we overlook, that intellectual versatility is the compensation for change, danger and trouble.... Nature never appeals to intelligence until habit and instinct are useless. There is no intelligence where there is no change and no need of change.”

“A series of prohibitions called the Law - I had already heard them recited - battled in their minds with the deep-seated, ever-rebellious cravings of their animal natures. This Law they were perpetually repeating, I found, and - perpetually breaking.”

“My pockets had always puzzled Weena, but at the last she had concluded that they were an eccentric kind of vase for floral decoration.”

“States organized for war will make war as surely as hens will lay eggs...”

“We look back through countless millions of years and see the great will to live struggling out of the intertidal slime, struggling from shape to shape and from power to power, crawling and then walking confidently upon the land, struggling generation after generation to master the air, creeping down the darkness of the deep; we see it turn upon itself in rage and hunger and reshape itself anew, we watch it draw nearer and more akin to us, expanding, elaborating itself, pursuing its relentless inconceivable purpose, until at last it reaches us and its being beats through our brains and arteries...It is possible to believe that all the past is but the beginning of a beginning, and that all that is and has been is but the twilight of the dawn. It is possible to believe that all that the human mind has accomplished is but the dream before the awakening; out of our lineage, minds will spring that will reach back to us in our littleness to know us better than we know ourselves. A day will come, one day in the unending succession of days, when beings, beings who are now latent in our thoughts and hidden in our loins, shall stand upon this earth as one stands upon a footstool, and shall laugh and reach out their hands amidst the stars.”

“The Time Traveller (for so it will be convenient to speak of him) was expounding a recondite matter to us.”
