We are now, measurably, reducing the availability of these life-supporting goods which we can think of (though only on the conditions of good health and good care) as self-renewing or "sustainable." We are also destroying rapidly the supplies of the fossil fuels, which are limited and not renewable, and on which we have become totally dependent.

There’s nothing under the ground that’s worth more than the little layer of topsoil sitting on top of it.

Want of imagination makes things unreal enough to be destroyed. By imagination I mean knowledge and love. I mean compassion. People of power kill children, the old send the young to die, because they have no imagination. They have power. Can you have power and imagination at the same time? Can you kill people you don’t know and have compassion for them at the same time?

I like the way that the history of the tree shapes the tree. There's no distinction between the tree and its history. You can lose yourself in that thought.

The most alarming sign of the state of our society now is that our leaders have the courage to sacrifice the lives of young people in war but have not the courage to tell us that we must be less greedy and wasteful.

Our destruction of nature is not just bad stewardship, or stupid economics, or a betrayal of family responsibility; it is the most horrid blasphemy. It is flinging God's gifts into His face, as if they were of no worth beyond that assigned to them by our destruction of them.

Analogies have tied things together for me, personally. The fundamental one for me is the analogy between your relationship to your spouse and your relationship to your place. Both need to be a settled commitment and both involve continuous learning and adjusting.
