The green thumb is equable in the face of nature's uncertainties; he moves among her mysteries without feeling the need for control or explanations or once-and-for-all solutions. To garden well is to be happy amid the babble of the objective world, untroubled by its refusal to be reduced by our ideas of it, its indomitable rankness.

A tension has always existed between the capitalist imperative to maximize efficiency at any cost and the moral imperatives of culture, which historically have served as a counterweight to the moral blindness of the market. This is another example of the cultural contradictions of capitalism - the tendency over time for the economic impulse to erode the moral underpinnings of society. Mercy toward the animals in our care is one such casualty.

Every peasant cuisine has incredible ingenious tricks for getting a lot of nutrition out of a small amount of ingredients. There are people who don't have the money to invest in better food, but perhaps they have the time.

Were the walls of our meat industry to become transparent, literally or even figuratively, we would not long continue to raise, kill, and eat animals the way we do.
