  We critically examine the non-Fermi liquid (NFL) behavior observed in heavy
fermion systems located close to a magnetic instability and suggest a
conceptual advance in physics in order to explain its origin. We argue that the
treatment of electronic states responsible for magnetism near the Quantum
Critical Point (QCP), should not be accomplished within the quantum mechanical
formalism; instead they should be treated semi-classically. The observed NFL
behavior can be explained within such a scenario. As a sequel we attempt to
discuss its consequences for the explanation of high-TC superconductivity
observed in Cuprates.
