 The dual-aspect approaches of Pauli and Jung and of Bohm and Hiley are conceptually more transparent and more promising. Although there is now a huge body of empirically documented mind-matter correlations that supports the Pauli-Jung conjecture, it lacks a detailed formal basis so far. Hiley’s work offers an algebraic framework which may lead to theoretical progress. A novel dual-aspect quantum proposal by Primas, based on the distinction between tensed mental time and tenseless physical time, marks a significant step forward, particularly as concerns a consistent formal framework.
