Among the philosophical issues raised by quantum theory, the alleged indeterminism of quantum-physical phenomena, as opposed to the determinism of classical physics, has stood at the center of discussion. There are various other much-debated problems which are directly or indirectly related to this issue or, more generally, the probabilistic character of quantum theory. Less attention has been paid to the questions of the stability of atoms and the specificity of their properties, which quantum theory was primarily designed to resolve. I argue that the indeterminism of quantum theory becomes less intriguing and can be better comprehended when seen in the light of these questions - or briefly, that “stability implies indeterminism, or chance.” Chance, in this respect, appears as an objective and legitimate mode of succession of otherwise stable and discrete well-determined states of certain physical systems.
