In re-reading the first chapter of McCloskey's The Bourgeois Virtues, I came across this quote from the Chief Rabbi of Great Britain, Jonathan Sacks:
"It is through exchange that difference becomes a blessing, not a curse."
Have the benefits of the specialization and exchange ever been presented more concisely and beautifully than in that one sentence?
UPDATE: The quote looks even better in the context of the whole paragraph:
from Jonathan Sack's book, the Dignity of Difference:
"I have suggested a different model and metaphor. The world is not a single machine. It is a complex, interactive ecology in which diversity -- biological, personal, cultural and religious -- is of the essence. Any proposed reduction of that diversity through the many forms of fundamentalism that exist today -- market, scientific or religious -- would result in a diminution of the rich texture of our shared life, a potentially disastrous narrowing of the horizons of possibility. Nature, and humanly constructed societies, economies and polities, are systems of ordered complexity. That is what makes them creative and unpredictable. Any attempt to impose on them an artificial uniformity in the name of a single culture or faith, represents a tragic misunderstanding of what it takes for a system to flourish. Because we are different, we each have something unique to contribute, and every contribution counts. A primordial instinct going back to humanity's tribal past makes us see difference as a threat. That instinct is massively dysfunctional in an age in which our several destinies are interlinked. Oddly enough, it is the market -- the least overtly spiritual of concepts -- that delivers a profoundly spiritual message: that it is through exchange that difference becomes a blessing, not a curse. When difference leads to war, both sides lose. When it leads to mutual enrichment, both sides gain."
