Validity is not just the product of logic, Bill. THere is such a thing as experiential validfity, personal perspectives borne out by experience. Valid means having merit compared to some sort of test, but the kind of Boolean logic you espouse is not the proper test for the validity of personal considerations. A person may believe that theuniverse works in such a way that maintaining a personal standard of ethics pays off over time. To a rigorous logician, that argument is netiher valid nor invalid, I guess. To a physicist it would seem irreverent. Oh, sorry, I meant irrelevant. But to the person living the life, it may asctually be working. WORKING truths are not scientific, they don't have to be. They simply have to work.

THe placebo effect is completely illogical, too. It must be mythical, I suppose....
