“Sufficiency isn't two steps up from poverty or one step short of abundance. It isn't a measure of barely enough or more than enough. Sufficiency isn't an amount at all. It is an experience, a context we generate, a declaration, a knowing that there is enough, and that we are enough.”
“We all do what we can, and it has to be good enough, and if it isn't good enough, it has to do.”
“It isn't enough to talk about peace. One must believe in it. And it isn't enough to believe in it. One must work at it.”
“Vision is not enough, it must be combined with venture. It is not enough to stare up the steps, we must step up the stairs.”
“It's not enough just to learn what there ISN'T; we need to know what there IS.”
“The generosity of the Earth allows us to feed all mankind; we know enough about ecology to keep the Earth a healthy place; there is enough room on the Earth, and there are enough materials, so that everybody can have adequate shelter; we are quite competent enough to produce sufficient supplies of necessities so that no one need live in misery.”
