"Freezing concentrates sugar , alcohol, and salt solutions as efficiently as heating distils water or alcohol from solutions. Open pans of maple sugar can have the surface ice removed regularly until a sugar concentrate remains. Salts in water, and alcohol in ferment liquors can be concentrated in the same way."

“If and when the whole world is secure, we have won a right to explore space, and the oceans. Until we have demonstrated that we can establish a productive and secure earth society, we do not belong anywhere else, nor would we be welcome elsewhere.”

“Order is found in things working beneficially together. It is not the forced condition of neatness, tidiness, and straightness all of which are, in design or energy terms, disordered. True order may lie in apparent confusion; it is the acid test of entropic order to test the system for yield. If it consumes energy beyond product, it is in disoder. If it produces energy to or beyond consumption, it is ordered.”

“We ourselves are part of a guild of species that lie within and without our bodies. Aboriginal peoples and the Ayurvedic practitioners of ancient India have names for such guilds, or beings made up of two or more species forming one organism. Most of nature is composed of groups of species working interdependently …”

“As we read this, we stand in the plane of the present; we are the sum of all our ancestors, and the origin of all our descendents. In terms of our model, we are at an ever-changing origin, located on the boundary of past and future. As well, we are spinning with the earth, spiralling with the galaxy, and expanding or contracting with the universe. As origins, we are on the move in time and space, and all these movements have a characteristic pulse rate.”

“A people without an agreed-upon common basis to their actions is neither a community nor a nation. A people with a common ethic is a nation wherever they live. Thus, the place of habitation is secondary to a shared belief in the establishment of an harmonious world community. Just as we can select a global range of plants for a garden, we can select from all extant ethics and beliefs those elements that we see to be sustainable, useful, and beneficial to life and to our community.”

“As non-scientists, most gardeners deprived of atomic-ray spectrometers, a battery of reagents, and a few million research dollars must look to signs of health such as the birds, reptiles, worms, and plants of their garden-farm. For myself, in a truly natural garden I have come to expect to see, hear, and find evidence of abundant vertebrate life. This, and this alone, assures me that invertebrates still thrive there. I know of many farms where neither birds nor worms exist, and I suspect that their products are dangerous to all life forms.”
