However, let's dig into this a bit deeper. The law of excluded middle is only called into question within the domain of the Copenhagen interpretation of quantum mechanics. Assuming the law of excluded middle truly is incompatible with this interpretation, which the majority of physicists accept for the time being, should the philosopher simply concede that the law of excluded middle is inapplicable on the quantum level? I suggest that the philosopher ought to give himself more credit and not view himself as inferior to the physicist. If any scientific theory, or interpretation of that theory, undermines any of the laws of logic, including the law of excluded middle, maybe it's time for scientists to abandon that theory or interpretation. The argument may be summarized as follows:
1. The law of excluded middle is inconsistent with the Copenhagen interpretation of quantum mechanics. (Premise)
2. One should not adopt inconsistent positions. (Premise)
3. Therefore, one should either abandon the law of excluded middle or the Copenhagen interpretation of quantum mechanics. (From 1 and 2)
Given the overwhelming support in favor of the law of excluded middle, it seems to me that if there is any inconsistency, then the Copenhagen interpretation ought to be abandoned. I don't think I'm any more out of line rejecting some scientific theory than a scientist is by making the absurd claim that philosophy is useless. After all, science presupposes various philosophical concepts: the laws of logic and mathematics, the principle of induction, and the uniformity of nature. These concepts are not observed by the scientist, but are presupposed by the scientist in order to allow his observations to be intelligible.
