[103] Much of the wage of high salaried persons will derive from custom and bargaining skill, but there will also be a serious part ‘productivity’.
[104] It is essential to read Hueting (1980) and Van Ierland et al. (2001) for a proper understanding of the issue of growth.
[105] Vide the ‘proof of God’ paragraph in chapter 19.
[106] This is not without problem, since there are many logics, such as standard, threevalued, fuzzy, intuitionistic logic, and my own scheme of ‘the logic of exceptions’ (that I use to solve the liar paradox, and Russells and Gödels problems). However, here it suffices to presume standard logic. Note that the earlier version of this chapter (article) used a ‘quantor free logic’, where the use of a variable indicates the ‘for all’ quantor, and a constant indicates the ‘there is’ quantor. A subtlety is that this distinguishes between “Not p
q”, that is equivalent to “p0 & ~q0”, and “~(p
q)”, that is equivalent to “p & ~q”.
[107] If we were to put the question to Arrow, my bet is that he likely prefers incompleteness to inconsistency.
[108] That there should be at least 3 topics is actually an axiom that we have taken for granted.
