Sci. 56 (2005),\nwhich concerns theories postulating that certain quantum observables have\ndeterminate values, corresponding to additional (often called ``hidden\u0027\u0027)\nvariables. I point out that it is far from clear, for most observables, what\nsuch a postulate is supposed to mean, unless the postulated additional variable\nis related to a clear ontology in space-time, such as particle world lines,\nstring world sheets, or fields.",
