| http://www.w3.org/ns/prov#value | - I agree with you that if you are to measure value you must measure it by the agency of some one commodity or other possessed of value,???that is what Mr. Malthus and we all propose to do, and the only difference between us is respecting the circumstances which are to determine the value,???the invariable value, of the commodity which we chuse for our measure.
