“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.”

“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.”

“Human beings are not inevitable, and our brief existence is not preordained to be extended into the distant future. If Homo sapiens is to have a continued presence on earth, humankind will reevaluate its sense of place in the world and modify its strong species-centric stewardship of the planet. Our collective concepts of morality and ethics have a direct impact on our species’ ultimate fate.”

“There are those who don't understand the nobility of horror fiction. 'Isn't there enough horror in the world?' they ask. For all other forms of literature, the value of human life is optional. For horror fiction, it's absolutely necessary. If we don't value the life of the threatened protagonist, we can't be scared. And through our fear, we better understand the individual fears and values of our species across the world.”

“We must remember what ruthless and utter destruction our own species has wrought, not only upon animals, such as vanished bison and the dodo, but upon its own inferior races. The Tasmanians . . . were entirely swept out of existence in a war of extermination waged by European immigrants, in the space if fifty years. Are we such apostles of mercy as to complain if the Martians warred in the same spirit?”
