Sorry, no etymologies found.


  • From the B-Theorist perspective, perhaps when we talk about redemption, we really mean that the temporal part of a person at some time T is morally better than the temporal part of a person at some earlier time T*.

    God and Time

  • In fact if we carry out this construction not just for a single structure A but for a family of models of a theory T, always using the same defining formulas, then the resulting structures will all be models of a theory T² that can be read off from T and the defining formulas.

    Model Theory

  • Rather he suggests a lot of special reduction relations which can be combined appropriately to connect two theories T and T².

    Structuralism in Physics

  • Then a state is operationally separated with respect to T if T's application does not change the result of applying the state to any element of the other subalgebra: it is operationally separable with respect to T if it is operationally separated, either with respect to T, or with respect to some other operation T* that coincides with the action of T on the other subalgebra.

    Holism and Nonseparability in Physics

  • Thus, Schaffner (1976, p. 618) holds that T reduces T² if and only if there is a corrected version of T², call it T²* such that

    Intertheory Relations in Physics

  • T, and the terms of T² are understood to have approximately the same meanings that they have in T, then Nagel calls the reduction of T² by T

    Intertheory Relations in Physics

  • There is nothing wrong with the VS observation about the fact that the variance of an estimate T* in an inverse regression is less than the variance of the target T, i.e.

    Variability: von Storch et al [2004] « Climate Audit

  • T produces a second theory, T*, which has the same theoretical virtues as T but a smaller set of ontological commitments.


  • Occam's Razor may be formulated as an epistemic principle: if theory T is simpler than theory T*, then it is rational (other things being equal) to believe T rather than T*.


  • Let T be the total science of the time, and let T* be a theory empirically equivalent to T with respect, not to their observational consequences, but with respect to their consequence regarding the phenomena in D.
