  4. . Reference here is first to Ludwig Wittgenstein's Tractatus Logico‐Philosophicus (London: Routledge & Kegan Paul, 1961), nos. 6.44, 6.45, and 6.522, and second to H. L. Dreyfus's reference to the later Martin Heidegger in H. L. Dreyfus, Richard Rorty, and Charles Taylor, “A Discussion [of Holism and Hermeneutics],” Review of Metaphysics 34 (1980): 53–55. For an account of Heidegger, Wittgenstein, and a thoroughgoing holism in the philosophy of science, see Richard Rorty, Philosophy and the Mirror of Nature (Oxford: Blackwell, 1980).

  7. . For a detailed account of Bohr's philosophical approach, see John Honner, “The Transcendental Philosophy of Niels Bohr,” Studies in History and Philosophy of Science 13 (1982): 1–29.
  8. . See, for example, Niels Bohr, Atomic Theory and the Description of Nature (Cambridge: Cambridge University Press, 1934), p. 5. On one occasion Bohr was taken to use “idolization” in the same context: see the transcript of an address given at Roosevelt University, February 4, 1958, MSS:23, p. 4.
  9. . Bohr repeatedly referred to the aphorism of Lao Tzu that “We are both actors and spectators on the stage of life.” See Bohr, Atomic Theory, p. 119, Atomic Physic., pp. 20, 63, and 81; and Essays 1958–1962 on Atomic Physics and Human Knowledge (London: Wiley, 1963), p. 15. His account of the conditions tor the possibility of experimental knowledge, given such a view, is discussed in Honner, “The Transcendental Philosophy of Niels Bohr.”
  10. . As reported in H. A. Kramers to Bohr, January 27, 1919, BSC:4. “A Fruitful Mysticism” is also the title of a chapter in Peter Robertson's history of the Niels Bohr Institute, The Early Years (Copenhagen: University of Copenhagen Academic Press, 1979).
  11. . Max Born to Albert Einstein, July 15, 1925, in M. Born, ed., The Born‐Einstein Letters (London: Macmillan, 1971), p. 84, where “sehr mystisch” has been weakly rendered as “rather mystifying.” See Einstein to Erwin Schrödinger in Karl Przibram, ed., Letters on Wave Mechanics (London: Vision, 1968), p. 31.
