Here is Wendell Berry in The Hidden Wound (Boston: Houston Mifflin, 1970), pages 100-101:
I am far from conceding anything to those who assume that the poor or anyone else can be improved by recourse to that carnival of waste and ostentation and greed known as “our high standard of living.” As Thoreau so well knew, and so painstakingly tried to show us, what a man most needs is not a knowledge of how to get more, but a knowledge of the most he can do without, and of how to get along without it. The essential cultural discrimination is not between having and not having or haves and have-nots, but between the superfluous and the indispensable. Wisdom, it seems to me, is always poised upon the knowledge of minimums; it might be thought to be the art of minimums. Granting the frailty, and no doubt the impermanence, of technology as a human contrivance, the man who can keep a fire in a stove or on a hearth is not only more durable, but wiser, closer to the meaning of fire, than the man who can only work a thermostat.
