The rationale for Newtonian gravitational attraction supports the concepts of inertial mass, and gravitational mass. This support tacitly imposes an equivalence for these designations of mass so differently defined. Using a dual application of Newton�s Universal Law of Gravitation leads to a denial of �free-fall�. This in turn leads to the denial of the Equivalence Principle in Newton�s own terms. At the foundation of Einstein�s relativistic theory of gravitation, the Equivalence Principle is stated as a postulate. Therefore, if my argument holds then Einstein�s theory of gravitation is based on a false principle.
