We shall not belabor the importance of having a clear idea of the difference between classificatory, comparative, and quantitative terms. Even though some of the goals that were set for theories of measurement of empirical attributes no longer seem viable, and some do not seem generally applicable, there is every reason to believe that suitable general goals for such theories will rely upon a distinction between quantitative and qualitative terms. The distinction seems also to have an intrinsic interest, even though some of the claims originally made for it, no longer seem historically accurate, or philosophically defensible. The subject, then, is quantitative terms in theories of the measurement of empirical attributes like length, mass, charge, and utility. We shall consider two problems.
This is part of a monograph. Quantity and Quality (Koslow 1982). Some of these results were prepared for a contribution to the Festschrift for Richard Bevan Braithwaite (Mellor 1980). Unfortunately, the paper reached the press a little too late for inclusion. This is but a small token of my gratitude and affection. I would also like to thank J.Barshay, H.Kyburg Jr.,D.T.Langendoen, D.Rosenthal, and R.Schwartz for some very helpful comments and discussions on earlier versions of this study. Although I cannot claim full credit for what is right in it, I do take full credit for any residual errors and shortcomings that still dog its pages.
