Theoreticity in Kyburg’s Measurement Theory
Theoreticity is closely connected in the (mainstream) philosophy of science to the idea of non-observability. A closer analysis of measurement, however, may give us a deeper perspective into this connection. This was done by Kyburg in his Theory and Measurement, where he argued that theory is much more pervasive then usually thought of -- even the simplest forms of measurement essentially invoke non-observables. In my article I advance Kyburg’s ideas and try to show that theoreticity implicitly invoked by Kyburg’s pervasive theory may be cast in terms of what I call “non-vagueness principle”. Further, I argue that this principle can provide for a natural demarcation between mature science and other more rudimentary forms of science.
