I do. In fact, we must. How would we talk about accuracy of a 
measuring apparatus, if there were not a meaningful distinction 
between a real magnitude and a measurement? To even discuss a 
measuring apparatus, we need to have a theory of the physical 
magnitudes which they are designed to measure.    (02)

More fundamentally, however, these are clearly distinct concepts. 
Magnitude is not an epistemic notion, but measurement is. And truth, 
perhaps unlike knowledge of truth, does not require verification or 
measurement to be meaningfully spoken of.    (03)
