Incidentally, consistent with Tom Sowell’s ideas on the constrained vs. the unconstrained visions outlined in his book, here is an appropriate quote from recent remarks by Pope Benedict: “The cry for the large scale has the whiff of morality; in contrast, limiting oneself to what is possible seems to be renouncing the passions of morality and adopting the pragmatism of the faint-hearted. But, in truth, political morality consists precisely in resisting the seductive temptation of the big words by which humanity and its opportunities are gambled away.” This rings as a pretty timely message to certain American politicians.
