Abstract

Two fundamental questions are addressed within the framework orthodox quantum mechanics. The first is the duality-nonduality conflict arising from the fact that our scientific description of nature has two disparate parts: an empirical component and a theoretical component. The second question is the possibility of meaningful free will in a quantum world concordant with the principle of sufficient reason, which asserts that nothing happens without a sufficient reason. The two issues are resolved by an examination of the conceptual and mathematical structure of orthodox quantum mechanics, without appealing to abstract philosophical analysis or intuitive sentiments.
