You know, I have repeatedly defended President Bush against the left on Iraq, even though I think he should have waited until the U.N. inspections were over. I don’t believe he went in there for oil. We didn’t go in there for imperialist or financial reasons. We went in there because he bought the Wolfowitz-Cheney analysis that the Iraqis would be better off, we could shake up the authoritarian Arab regimes in the Middle East, and our leverage to make peace between the Palestinians and Israelis would be increased.
The sciences do not try to explain, they hardly even try to interpret, they mainly make models. By a model is meant a mathematical construct which, with the addition of certain verbal interpretations, describes observed phenomena. The justification of such a mathematical construct is solely and precisely that it is expected to work.John von Neumann, “Method in the Physical Sciences”, in The Unity of Knowledge (1955), ed. L. G.
