I have painstakingly scanned (as in: put on a scanner to make a PDF) 352 pages of a hard copy version of Nozick's 1963 dissertation The Normative Theory of Individual Choice.
I don't have page 57.
I got the paperwork from ProQuest. I recall that they checked and found that page 57 isn't on the microfilm.
So, I ask: does anybody have page 57?
There is a possibility that Nozick miss-numbered the pages. I'll give you the last and first bits of pages 56 and 58. What do you think (especially of the double "that")?
If you happen to have the 1990 book The Normative Theory of Individual Choice, which is out-of-print, I would really appreciate it if you'd have a look for comparison and whether there is a page missing from the dissertation or not. In the dissertation, the section is named "Section 3: On a Tentative Account of Preference and Indifference".
NB: The work has some historical significance as it may very well contain the first definition of the concept that later became known as "common knowledge".
So far as I know, the first statement that game theory needed this infinite layering of knowledge appeared in my doctoral dissertation, The Normative Theory of Individual Choice (Princeton University, 1963), published by Garland Publishing (New York, 1990), pp. 273-274. [...]
