“The human species was given dominion over the earth and took the opportunity to exterminate other species and warm the atmosphere and generally ruin things in its own image, but it paid this price for its privileges: that the finite and specific animal body of this species contained a brain capable of conceiving the infinite and wishing to be infinite itself.”

“Science, already oppressive with its shocking revelations, will perhaps be the ultimate exterminator of our human species - if separate species we be - for its reserve of unguessed horrors could never be borne by mortal brains if loossed upon the world.”

“Life is a hideous thing, and from the background behind what we know of it peer daemoniacal hints of truth which make it sometimes a thousandfold more hideous. Science, already oppressive with its shocking revelations, will perhaps be the ultimate exterminator of our human species—if separate species we be—for its reserve of unguessed horrors could never be borne by mortal brains if loosed upon the world.”

“Yes, the human race is a small species in an infinite universe filled with many other planets and many other things, but though small; this race is bearer of very great and big things: Destiny, Virtue, Hope, Love... and that's what makes this species different. That's what makes this species very shiny and very visible and very important, in a whole, whole, big, big, vast, expanding universe!”

“It must be remembered: fields end freedom. Whatever the astonishing subsequent achievements of civilization, it had a little recognized price: humanity itself became one of its own domesticated species. We enslaved ourselves to conquer.”

“Man is a moral animal abandoned in an amoral universe and condemned to a finite existence with no other prupose than to perpetuate the natural cycle of the species.”
