Since the Pauli-Jung conjecture of an ontological unity of Mind and Matter was formulated almost one century ago, there has been a lot of interest in trying to define a model based on the principles of Quantum Mechanics. In particular, Quantum Mechanics seems to offer a possibility to bridge the epistemological gap between Mind and Matter to build a model of what the 17th century philosopher Gerhard Dorn has called the "Unus Mundus", i.e. the ontological healing of the perceived duality of the Universe. Following other authors who have treated this matter before us, in the current paper we define a very simple model of Mind and Matter represented by two qubits and we discuss their interaction and their entanglement. In particular, we show how a generic Hamiltonian can be divided in four components. Two of them represent local evolutions of the qubits, each one acting on one of the two qubits and not on the other one. The other two define two different modes of interaction that we describe as the general evolution of the Unus Mundus and the interaction generating synchronicity. We conclude with a discussion on the different times governing the evolution of the Mind-Matter ensemble.
