“These, then, are some of the basic principles of ecology—interdependence, recycling, partnership, flexibiility, diversity, and, as a consequence of all those, sustainability …the survival of humanity will depend on our ecological literacy, on our ability to understand these principles of ecology and live accordingly.”

Fritjof Capra (1939) American physicist

“Part of our evolutionary heritage is the ability to adapt -- species that survive, adapt. Humans adapt by altering their priorities to match evolving values.”

“Our ability to block our experience is an evolutionary dead end. Rather than experiencing and transforming pain, conflict, and fear, we often divert or dampen them with a kind of unwitting hypnosis. Over a lifetime, more and more stress accumulates. There is no release, and our consciousness narrows. The floodlight shrinks into the slender beam of a flashlight. We lose the vividness of colors, sensitivity to sounds, peripheral vision, sensitivity to others, emotional intensity. The spectrum of awareness becomes ever narrower.”

Marilyn Ferguson (1938–2008) American writer

“If the inexpressible cruelties of slavery could not stop us, the opposition we now face will surely fail. We will win our freedom because the sacred heritage of our nation and the eternal will of God are embodied in our echoing demands.”

Context: I have no fear about the outcome of our struggle in Birmingham, even if our motives are at present misunderstood. We will reach the goal of freedom in Birmingham and all over the nation, because the goal of America is freedom. Abused and scorned though we may be, our destiny is tied up with America's destiny. Before the pilgrims landed at Plymouth, we were here. Before the pen of Jefferson etched the majestic words of the Declaration of Independence across the pages of history, we were here. For more than two centuries our forebears labored in this country without wages; they made cotton king; they built the homes of their masters while suffering gross injustice and shameful humiliation -and yet out of a bottomless vitality they continued to thrive and develop. If the inexpressible cruelties of slavery could not stop us, the opposition we now face will surely fail. We will win our freedom because the sacred heritage of our nation and the eternal will of God are embodied in our echoing demands.
