“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.”

“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.”

“In the future, a part of this class - individuals particularly sensitive to this question of the future - will realize that their happiness depends on that of others, that the human species can only survive united and pacific. They will cease to belong to the mercantile innovative class, and refuse to put themselves at the service of pirates. They will become what I call transhumans (who will give birth to a new order of abundance). ”

“Though it may be the peculiar happiness of Socrates and other geniuses of his stamp, to reason themselves into virtue, the human species would long ago have ceased to exist, had it depended entirely for its preservation on the reasonings of the individuals that compose it." Par 1, 36”

“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.”

“It must be remembered that no art lives by nature, only by acts of voluntary attention on the part of human individuals. When these are not made it ceases to exist.”
