Abstract
Physical foundations for the Lorentz-Dirac equation of a classical point charge are described. It is shown that, under appropriate conditions, this equation is closely related to the ordinary Lorentz force exerted on a particle whose charge is distributed continuously inside a very small volume. A mathematical analysis of Parrott's assault on the Lorentz-Dirac equation shows that most of his claims are unjustified and the rest do not deny the physical meaning of the equation.
