 A final moral concerns terminology. Why did such serious people take so seriously axioms which now seem so arbitrary? I suspect that they were misled by the pernicious misuse of the word “measurement” in contemporary theory. This word very strongly suggests the ascertaining of some preexisting property of some thing, any instrument involved playing a purely passive role. Quantum experiments are just not like that, as we learned especially from Bohr. The results have to be regarded as the joint product of “system” and “apparatus”, the complete experimental set-up. But the misuse of the word “measurement” makes it easy to forget this and then to expect that the “results of measurements” should obey some simple logic in which the apparatus is not mentioned. The resulting difficulties soon show that any such logic is not ordinary logic. It is my impression that the whole vast subject of “Quantum Logic” has arisen in this way from the misuse of a word. I am convinced that the word “measurement” has now been so abused that the field would be significantly advanced by banning its use altogether, in favour for example of the word “experiment”.
