We must use both methods. Imperfect models are much better than no model
at
all! Uncertainty makes complete theory impossible, but one need not know
the
physics of fire to know where to keep you hand. That is a theory. There
is
very little uncertainty about it. There is little uncertainty about the
limits to growth, or the suffering of the poor. We can act on that
knowledge. Knowing nothing is not reality. Knowing everything is not
reality.
