So far as I can see, coalescence of faith and truth has not been achieved anywhere in the world, not even in American departments of economics... - William Hardy McNeill

My principles require me merely to invite you to agree, while expecting the contrary. Missionaries do not make converts with such a message: millions are not mobilized by such tepid phrases. That is why the merely intellectual compulsion to regard human diversity and flux is unlikely to prevail against simpler systems of misunderstanding truly capable of altering the world in which we live.

The principle obstacle to human dominion over the rain forests is still the rich variety of parasites lying in wait for intruders.

I am old enough to remember well the depression years of the middle 1930s, when economists were quite unable to agree on what public policy should be, and when President Hoover, in need of advice, turned by preference to sociologists to study and illuminate recent social trends. The circumstances of the 1980s seem similar; perhaps contemporary confusions and dismay will mark the dethronement of economics from its privileged place among the social sciences — but perhaps not.
