Quotes by Ecologists

Natural selection favors the forces of psychological denial. The individual benefits as an individual from his ability to deny the truth even though society as a whole, of which he is a part, suffers. Education can counteract the natural tendency to do the wrong thing, but the inexorable succession of generations requires that the basis for this knowledge be constantly refreshed.

The border between personal and transpersonal experience is a complex region. It is a territory often filled with spiritual and religious views. Within psychology it was a significant preoccupation of William James, Carl Jung, Abraham Maslow, and many others. But these margins may be seen in other ways as well. There is substantial evidence from psychological studies of personal space that we carry body boundaries of extended space around ourselves. These spatial extensions are not only personal. They may be felt by groups as well—in terms of shared “social” space, communal territories, or even national identities.

Whenever we take the focus off ourselves and move it outward, we benefit. Life's most fortunate ironies are that what's best for the long run is best now, and selflessness serves our interests far better than selfishness. The wider our circle of considerations, the more stable we make the world—and the better the prospects for human experience and for all we might wish. The core message of each successive widening: we are one. The geometry of the human voyage is not linear; it's those ripples whose circles expand to encompass self, other, community, Life, and time.

What we are doing to the forests of the world is but a mirror reflection of what we are doing to ourselves and to one another.

The revelation is this: don't wait for some revelation. We make our own luck.

...the chief cause for the impending collapse of the world - the cause sufficient in and by itself - is the enormous growth of the human population: the human flood. The worst enemy of life is too much life: the excess of human life.

I am impressed anew by... how much the harshness that challenges life is what causes the beauty. Birds fly because they must escape predators and search for food. Trees grow skyward because they compete fiercely with other trees for light. Living things need something to push off of. Each of us needs challenges to give us the right shape.

That land is a community is the basic concept of ecology, but that land is to be loved and respected is an extension of ethics.

When I call to mind my earliest impressions, I wonder whether the process ordinarily referred to as growing up is not actually a process of growing down; whether experience, so much touted among adults as the thing children lack, is not actually a progressive dilution of the essentials by the trivialities of living.
