Ruin is the destination toward which all men rush, each pursuing his own best interest in a society that believes in the freedom of the commons.

However, I think the major opposition to ecology has deeper roots than mere economics; ecology threatens widely held values so fundamental that they must be called religious.

The god who is reputed to have created fleas to keep dogs from moping over their situation must also have created fundamentalists to keep rationalists from getting flabby. Let us be duly thankful for out blessings.

Economists (and others) who are satisfied with nature-free equations develop a dangerous hubris about the potency of our species

The three filters [against folly] operate through these particular questions: Literacy: What are the words? Numeracy: What are the numbers? Ecolacy: And then what?

We see only what we have names for.

Ecological differentiation is the necessary condition for coexistence.
