— Galileo Galilei"The vain presumption of understanding everything can have no other basis than never having understood anything. For anyone who had ever experienced just once the perfect understanding of one single thing, and had truly tasted how knowledge is accomplished, would recognize that of the infinity of other truths he understands nothing."

A finer body of men has never been gathered by any nation than the men who have done the work of building the Panama Canal; the conditions under which they have lived and have done their work have been better than in any similar work ever undertaken in the tropics; they have all felt an eager pride in their work; and they have made not only America but the whole world their debtors by what they have accomplished.
— Theodore Roosevelt

What the new fertilizer technology has accomplished for the farmer is clear: more crop can be produced on less acreage than before. Since the cost of fertilizer, relative to the resultant gain in crop sales, is lower than that of any other economic input, and since the Land Bank pays the farmer for acreage not in crops, the new technology pays him well. The cost-in environmental degradation-is borne by his neighbors in town who find their water polluted. The new technology is an economic success-but only because it is an ecological failure.
