“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.”

“The anthropologists got it wrong when they named our species Homo sapiens ('wise man'). In any case it's an arrogant and bigheaded thing to say, wisdom being one of our least evident features. In reality, we are Pan narrans, the storytelling chimpanzee.”

“Evolution, energy, and ethics are the core elements that will guide us along the challenging path toward the Life Era: the first - evolution - because a good understanding of our universal roots and of our place in the cosmic scheme of things will help us create a feasible future course; the second - energy - because our fate will bear strongly on the ways that humankind learns to use energy efficiently and safely; and the third - ethics - because global citizenship and a planetary society are crucial factors in the survival of our species.”

“We have a responsibility toward the other life-forms of our planet whose continued existence is threatened by the thoughtless behavior of our own human species. . . . Environmental responsibility – for if there is no God, then, obviously, it is up to us to put things right.”

“Our self-awareness impresses itself on us so cogently, as individuals and as a species, that we cannot imagine ourselves out of existence, even though for hundreds of millions of years humans played no part in the flow of life on the planet. When Teilhard de Chardin wrote, "The phenomenon of Man was essentially foreordained from the beginning," he was speaking from the depth of individual experience, which we all share, as much as from religious philosophy. Our inability to imagine a world without Homo sapiens has a profound impact on our view of ourselves; it becomes seductively easy to imagine that our evolution was inevitable. And inevitability gives meaning to life, because there is a deep security in believing that the way things are is the way they were meant to be.”

“Human can surprise you sometimes. An unpredictable species, Homo sapiens”
