Brad's response makes me feel somewhat like a British Idealist in the  
18th century might have felt after perusing Boswell's account of Dr.  
Johnson's refutation of idealism--kicking a stone furiously, "I refute  
it thus", said Johnson. Let me say a little in response:

I'm sorry to be confusing. Brad had asked for the sense in which  
Enlightenment thinkers were foundationalists. I picked the British  
empiricists as examples, since they are the thinkers most relied-upon in  
standard accounts of the methodology of economics. The "dogmatism" of  
empiricism is Quine's territory, of course. So let me use some of his  
insights. Most famously, Quine emphasized the way theory never confronts  
the data in atomic sized bits. Any particular theory can be "saved" by  
suitable reinterpretation of other bits. The hard-core of neoclassical  
economics is rational choice theory. This is itself never "tested" :  
instead, in order to be a candidate for explanation at all, by the rules  
of the neoclassical game, a proposed account must specify the  
maximization problem to be solved by the "agents". Otherwise, we are guilty 
of "ad-hoccery" and "implicit theorizing". Awareness of the dogmatic role 
of  
rational choice theory in the neoclassical project (post Quine and post  
McCloskey) might lead to humility and the willingness to appreciate and  
encourage a plurality of paradigms which do not put rational choice  
theory in their hard core. Neither logic nor "the data" compel such a 
choice.

All of this seems to me horribly likely.

Look at the way you've restricted yourself already. If Murray can show  
you in the data that the welfare system did substantially reduce labor  
supply, and undoing it increases it, you would applaud the "reform". A  
feminist economist would remind you that the net effect here would almost  
certainly be a reduction in labor, where the latter is understood to  
include non-wage, reproductive,"caring" labor--probably the most important  
labor any sustainable economy has to do, and a type that is in obvious  
ways inappropriately modelled with rational choice techniques. (See Sue  
Himmelweit, "The discovery of unpaid work", *Feminist Economics* 1, 
#2:1-19).

Showing that AFDC has a small "excess burden" is fine. Don't imagine  
though that this "empirical question" is what's being debated in the  
welfare reform debate. The Murrays and Gilders are making moral arguments  
that need to be answered if there is to be a chance of defeating  
repugnant policies. They rely on stilted conceptions of freedom and 
autonomy  
that are part of the deep appeal of neoclassical economics generally,  
conceptions it behooves us to pay attention to, contest and challenge. They 
have  
managed to convince people that the very real destruction of community  
and family they are seeing stems from the behemoth state, and not from  
the "marketization of everything" that policy has, however haltingly,  
served to palliate to an extent. Above all will this sort of work require  
that we leave our treasured fact/value distinction behind--another,  
perhaps the most important, empiricist dogma to add to Quine's list.
