1. E.J. Lowe claims that quantum physics provides examples of ontic indeterminacy, of vagueness in the world. Any such claim must confront the Evans-Salmon argument to the effect that the notion of ontic indeterminacy is simply incoherent (Evans 1978, Salmon 1981: 243-46). Lowe argues that a standard version of the Evans-Salmon argument fails quite generally (Lowe 1994). Harold Noonan (1995) ha...

This article discusses the perceptual phenomenon of visual indeterminacy in an art historical and scientific context and considers its role in certain heightened states of awareness.

These concepts imply that economies differ with respect to their growth rates on the transition path (local indeterminacy) as well as their long−run growth rates (global indeterminacy). While the empirical density function of the levels of aggregate GDP has been the subject of a great many studie...
