But we can do nothing for the human future that we will not do for the human present. For the amelioration of the future condition of our kind we must look, not to the wealth or the genius of the coming generations, but to the quality of the disciplines and attitudes that we are preparing now for their use.

We had entered an era of limitlessness, or the illusion thereof, and this in itself is a sort of wonder. My grandfather lived a life of limits, both suffered and strictly observed, in a world of limits. I learned much of that world from him and others, and then I changed; I entered the world of labor-saving machines and of limitless cheap fossil fuel. It would take me years of reading, thought, and experience to learn again that in this world limits are not only inescapable but indispensable.

In this state of total consumerism-which is to say a state of helpless dependence on things and services and ideas and motives that we have forgotten how to provide ourselves-all meaningful contact between ourselves and the earth is broken. We do not understand the earth in terms either of what it offers us or of what it requires of us, and I think it is the rule that people inevitably destroy what they do not understand.

We have the world to live in on the condition that we will take good care of it. And to take good care of it we have to know it. And to know it and to be willing to take care of it, we have to love it.

Nature is always trying to tell us that we are not so superior or independent or alone or autonomous as we may think.

We clasp the hands of those who go before us.

Like the water of a deep stream, love is always too much. We did not make it. Though we drink till we burst, we cannot have it all, or want it all. In its abundance it survives our thirst. In the evening we come down to the shore to drink our fill, and sleep, while it flows through the regions of the dark. It does not hold us, except we keep returning to its rich waters thirsty. We enter, willing to die, into the commonwealth of its joy.
