  Quantum mechanics in the Wigner-von Neumann interpretation is presented. This
is characterized by 1) a quantum dualism between matter and consciousness
unified within an informational neutral monism, 2) a quantum perspectivism
which is extended to a complementarity between the Copenhagen interpretation
and the many-worlds formalism, 3) a psychophysical causal closure akin to
Leibniz parallelism and 4) a quantum solipsism, i.e. a reality in which
classical states are only potentially-existing until a conscious observation is
made.
