Evidence That Bohr Knew Of William James's Complementarity Many Years Before Bohr Presented His Version For Physics - Quotes Of Bohr's Version For Physics

Many quotes of Bohr’s version of complementarity specifically for physics from the earliest days of quantum mechanics through 1955 are presented. A quote from Heisenberg’s Nobel Lecture regarding Bohr’s complementarity for physics is also presented. Complementarity was originally proposed by William James (1842-1910), the American psychologist, in 1890 in “The Principles of Psychology”. James’s definition in the original work appears at the following website: https://archive.org/details/theprinciplesofp01jameuoft/page/206/mode/2up?q=complementary . The website will read the quote. Evidence that Bohr borrowed James’s complementarity and adapted it to physics is presented. Bohr adapted James’s complementarity to physics by introducing an unavoidable physical interaction between a physical measuring instrument and the physical system measured. This physical interaction has an aspect that cannot be controlled that Bohr thought allowed for the application of the uncertainty principle.
