David Mermin seems to advocate the view of theoretical paradoxes and controversies of quantum mechanics and field theory as problems of “tools” of a linguistic or otherwise technical nature. His advice is not to “make life harder than it needs to be.” First, philosophical reduction of a fundamental science to a human tool goes against the main quest of science – the quest for objective truth about the universe. Second, the suggested advice seems more conducive to peace of mind than to scientific inquiry. Paradoxes and contradictions have always been a rich source of inspiration and contemplation for those who are seeking new knowledge.
