In 1776 philosopher Jeremy Bentham wrote a phrase that continues to be central to our modern way of thinking: "[I]t is the greatest happiness of the greatest number that is the measure of right and wrong."
That phrase has morphed into the familiar one cited in the title of this piece. Happiness, however, has been reinterpreted first as "good" meaning something which gives pleasure, a move toward a kind of hedonism. "Good" has, however, become associated with "goods," that is, objects which consumers and businesses buy to further their personal and occupational goals.
This drift from the original meaning of what Bentham called his "fundamental axiom" is, in part, why we are addicted to economic growth and the consumerism that derives from it. We believe that "goods" are good for us and so more "goods" will always bring more good in their wake.
