Permaculture ethics and design principles
I snagged this from an essay by David Holmgren, in which he discusses the 12 permaculture principles. I know from experience that permaculture has a lot of connotations and meanings to many different kinds of people. The most common association is with gardening, and rightfully so, that's where a lot of action happens. But David has a grace in which he describes the purposes and intents of permaculture; beyond a way of gardening or a set of skills, but as a means of designing, managing and improving the actions of humans and our settlements.
