Chapter 8 ought to be seen as the conceptual core of the book. Based on the observation that time as such is neither mental nor material, Primas posits a tripartite structure of the total universe of discourse with a temporal domain, an atemporal mental domain, and an atemporal material domain. Assuming that these domains are non-Boolean, they are holistically correlated, very much in the spirit of quantum entanglement. If all three of them are holistically correlated, any strict distinction between time, mind and matter gets lost, and we regain the idea of an undivided universe for which Primas used the term unus mundus in his earlier publications on the subject. Bilateral correlations between the mental and the material yield mind-matter correlations, and bilateral correlations between each of these two domains and the temporal domain introduce mental (psychological) and material (physical) time.
