Any economic law corresponds to the second mode of uncertainty Bernoulli. The second mode is when the evidential basis (e) follows necessarily the fact (f), but instead we have no evidence (e). In this mode usually would place our stories: building a coherent but uncertain in succession. Economic laws are consistent but not always rely on assumptions that comply. For this reason there is no contradiction in that two contradictory theories have deserved the Nobel Prize Sayings, proverbs, ethics, social laws and economic models are a toolbox, depending on the circumstance that may be useful or not.
