To the extent that individuals are really individual, each an autonomous end in himself, to that extent they must be somewhat mysterious and inaccess… - Kenneth Arrow

In any case the empirical evidence can only be made meaningful with at least a minimum of theoretical analysis.

May I remark, especially for the benefit of economists, that consideration of the medical care market and of the insurance situation represents not only an application of economic principles but also a reconsideration of some of the principles that we take for granted.

The problem I have with utilitarianism is not that it is excessively rational, but that the epistemological foundations are weak. My problem is: What are those objects we are adding up? I have no objection to adding them up if there's something to add. But the one thing I retain from utilitarianism is that, basically, judgements are based on consequences. Certainly that's the sort of thing we do in the theory of the single individual under uncertainty; you make sure utility is defined only over the consequences. I view rights as arrangements which may help you in achieving a higher utility level.
