This question <65|58> overall <89|91> Hans: <89|92>.  
  Question 72: What is the difference between labor and labor power?   
  [90] Hans: Labor power need not be a commodity   The second of the two answers to 72, MsMarx's [65], is very good. The only thing MsMarx overlooks is that under commodity production labor power exists and has real economic effects even if it is not a commodity itself.   
  Here is the other answer, Chuck's [58], with my comments:   
  Labor is the human act of producing an actual commodity.   
  By an “actual commodity” you apparently mean what Marx calls the “body” of the commodity, the physical thing that makes up the commodity. (A commodity is more than a physical thing; it is a physical thing endowed with social powers).   
  labor in turn produces use value.   
  This sentence seems to be a re-wording of the first sentence, using Marx's terminological convention to write “a use value” instead of “the body of a commodity”. But why did you write “in turn”?   
  Labor power on the other hand is the average amount of labor that every unit of labor gives.   
  Look at this sentence closely; it does not make any sense. We are using email here so that we can formulate our thoughts a little more carefully than that.   
  Labor power is the amount of effort and the skill level that is required in order to produce a good.   
  This might be a possible explication of the phrase “labor power is potential labor”, but it does not convey the universality of labor power. It is a central aspect of Marx's definition of labor power that the same labor power can give rise to various kinds of labor. Your definition should be rephrased along the following lines: “labor power is the ability to exert goal-directed effort, and to learn and use various skills, in order to produce various commodities.”
