“Having people in different optimal environments increases the chances of survival of the human race as a whole. It is nature's way to preserve her species.”

“Nature can't evolve a species that hasn't the will to survive. Individuals might be bred to sacrifice themselves, but the race as a whole can never cease to exist.”

“Once it was necessary that the people should multiply and be fruitful if the race was to survive. But now to preserve the race it is necessary that people hold back the power of propagation.”

“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!”

“The basic common denominator of all life is the urge to survive, and the survival of life on Planet Earth is achieved only as a shared initiative with and through all life-forms. Life is a joint effort; no 'man' separate from 'nature.' Homo sapiens as individuals and as species are as much a part of life's overall thrust for survival as any other species. As living organisms, we are part if the greater whole, and as such, we are embodied with exactly the same fundamental purpose: to survive. And to do so--as individuals, families, groups, and as a species--we have to live in dynamic collaboration with the plant and animal kingdoms in a healthy, life-sustaining environment.”

“For the human race is, more than any other species, at once social by nature and quarrelsome by perversion.”
