6. Mathematics / A. Nature of Mathematics / 4. Using Numbers / c. Counting procedure
Parsons says counting is tagging as first, second, third..., and converting the last to a cardinal [Parsons,C, by Heck]
     Full Idea: In Parsons's demonstrative model of counting, '1' means the first, and counting says 'the first, the second, the third', where one is supposed to 'tag' each object exactly once, and report how many by converting the last ordinal into a cardinal.
     From: report of Charles Parsons (Frege's Theory of Numbers [1965]) by Richard G. Heck - Cardinality, Counting and Equinumerosity 3
     A reaction: This sounds good. Counting seems to rely on that fact that numbers can be both ordinals and cardinals. You don't 'convert' at the end, though, because all the way you mean 'this cardinality in this order'.
7. Existence / D. Theories of Reality / 10. Vagueness / b. Vagueness of reality
To say reality itself is vague is not properly intelligible [Dummett]
     Full Idea: The notion that things might actually be vague, as well as being vaguely described, is not properly intelligible.
     From: Michael Dummett (Wang's Paradox [1970], p.260)
     A reaction: It seems hard to disagree with this. It seems crazy that a pile of grain, or the hair on someone's head, are vague, and even quantum indeterminacies are not very well described as 'vague'. Vagueness is a very human concept.
24. Political Theory / D. Ideologies / 1. Ideology
Ideology is 'socially necessary illusion' or 'socially necessary false-consciousness' [Adorno, by Finlayson]
     Full Idea: Adorno defines ideology as 'socially necessary illusion' or 'socially necessary false-consciousness' (and the young Habermas accepted something like this definition).
     From: report of Theodor W. Adorno (works [1955]) by James Gordon Finlayson - Habermas Ch.1:11
     A reaction: The marxism seems to reside in the view that such things are always 'false'. If they gradually became 'true', would they cease to be ideology? Is it impossible for widespread beliefs to be 'true'?
