Query: The Quantum Mechanics of Being and Its Manifestation   How can quantum mechanics be (i) the fundamental theoretical framework of
contemporary physics and (ii) a probability calculus that presupposes the
events to which, and on the basis of which, it assigns probabilities? The
question is answered without invoking knowledge or observers, by interpreting
the necessary distinction between two kinds of physical quantities -
unconditionally definite quantities and quantities that have values only if
they are measured - as a distinction between the manifested world and its
manifestation.
