Consider now the acceleration due to the sphere of mass M experienced by a particle in the vicinity of the body of mass m. With R as the distance from the center of M to the center of m, let ∆ r be the ( relatively small ) distance of the particle from the center of the body of mass m. For simplicity, distances are first considered only in the direction pointing towards or away from the sphere of mass M. If the body of mass m is itself a sphere of radius ∆ r, then the new particle considered may be located on its surface, at a distance ( R ± ∆ r ) from the centre of the sphere of mass M, and ∆ r may be taken as positive where the particle's distance from M is greater than R. Leaving aside whatever gravitational acceleration may be experienced by the particle towards m on account of ms own mass, we have the acceleration on the particle due to gravitational force towards M as:

Hall and Popkin defend Mill against this accusation pointing out that he begins Chapter Four by asserting that “ that questions of ultimate ends do not admit of proof, in the ordinary acceptation of the term ” and that this is “ common to all first principles .” According to Hall and Popkin, therefore, Mill does not attempt to “ establish that what people do desire is desirable but merely attempts to make the principles acceptable .” The type of “ proof ” Mill is offering " consists only of some considerations which, Mill thought, might induce an honest and reasonable man to accept utilitarianism ".
