Abstract
A nonunitary dynamics for a macroscopic object arises as a natural consequence of a universally valid Schrödinger equation and thus need not be postulated ad hoc. The density-matrix formalism does not, however, allow one to deduce classical states (particle trajectories) without invoking additional principles.Keywords
