This paper is concerned with the description of the process of measurement within the context of a quantum theory of the physical world. It is noted that quantum mechanics permits a quasi-classical description of those macroscopic phenomena in terms of which the observer forms his perceptions. Thus, the process of measurement in quantum mechanics can be understood on the quasi-classical level by transcribing from the strictly classical observables of Newtonian physics to their quasi-classical counterparts the known rules for the measurement (...) of the former. The remaining physical problem is the delineation of the circumstances in which the correlation of a peculiarly quantum mechanical observable A with a classically measurable observable B can result in a significant measurement of A. This is undertaken within the context of quantum theory. The resulting clarification of the process of measurement has important implications relative to the philosophic interpretation of quantum mechanics. (shrink)

Beginning with a reflection on ‘conceptual schemes’ and ‘very’ ideas and proceeding to examine different approaches to thinking philosophy of science not only with Kant but also between traditional analytic and hermeneutico-phenomenological approaches, this essay features a review of Kant’s 1755 solar nebular hypothesis and a reading of Nietzsche and Kant on cosmology along with a reflection on chemistry and the properties of cinnabar. Overall it is argued that a philosophy of science must be critical rather than normative/prescriptive. Seeking to (...) raise the question of science along with the question of truth, the essay also raises the question of esoteric historiography in science, including alchemy. (shrink)
