I now wish to propose a new dualism, but not a substance dualism: Res potentia--ontologically real Possibles that do not obey the Law of the Excluded Middle, and Res extensa--ontologically real Actuals that do obey the Law of the Excluded Middle, linked by measurement, (1).
Here measurements create Actuals that do obey the law of the excluded middle, so, I want to hope, must be located in space and time, or spacetime, the latter only if quantum mechanics can ever be formulated with respect to General Relativity.
Should you plan to camp out for the night?...The proto-human who had...[a] disposition to take seriously the
law of the excluded middle, and who avoided contradictions, survived and reproduced better than he/she who did not." For better or worse, argue the evolutionary critics, we are descendants of that savvy proto-human.
