“Anthropocentric as [the gardener] may be, he recognizes that he is dependent for his health and survival on many other forms of life, so he is careful to take their interests into account in whatever he does. He is in fact a wilderness advocate of a certain kind. It is when he respects and nurtures the wilderness of his soil and his plants that his garden seems to flourish most. Wildness, he has found, resides not only out there, but right here: in his soil, in his plants, even in himself...
But wildness is more a quality than a place, and though humans can't manufacture it, they can nourish and husband it...
The gardener cultivates wildness, but he does so carefully and respectfully, in full recognition of its mystery.”
