The Lorentz-Abraham-Dirac equation is not the correct equation of motion: (
1) it does not yield the law of inertia uniquely; (2) it is of third order
rather than of second order; and (3) it allows a self-force also in the abs
ence of an external force. The correct equation is derived. (C) 2001 Elsevi
