| Variables | Russell | XXI I Variables/Russell/Gödel: exist only to enable truth function. >Truth functions. Finite/Infinite/Ramsey: the problem of solving infinite propositions is not so critical. - Gödel: then Russell’s Apercu that propositions about classes can be interpreted as propositions about their elements literally becomes true, provided that n is the number of the (finite) individuals in the world, and provided we neglect the zero class. >Proposition, >Classes/Russell, >Empty set, >Individual/Russell. I 28 Pseudo-variable/Peano/Russell: the symbol (x). φ x denotes a particular proposition and there is no sense of difference between (x). j x and (y). φ y if they occur in the same context. - ((s)> Quine: alphabetical variant). - o is x in (x) φ x not an ambiguous part of an expression and such an expression itself remains the bearer of a very specific meaning despite the ambiguity of the x in φ x. Pseudo-variables: exist if the extension does not go over the entire range. A proposition with a state of affairs x is not a function of x. Extension: is the function of which all or some values are asserted. I 29 Ambiguous assertion and the real variable: any arbitrary value φ x of the function φ x^ can be asserted. - Real Variable: φx. - If x varies, a different proposition results. I 30 Pseudo-variable: is obtained if we put a universal quantifier before it. I 73 Pseudo-Variable: several possible values can be meant. Descriptions always contain pseudo-variables. Sentences without pseudo-variables: are observation sentences e.g. This is red. I 74 Pseudo-Variable/Principia Mathematica(1)/Russell/(s): E.g. (y).φ(x,y), which is a function of x - here y is a pseudo-variable, x is the real variable. - ((s) E.g. everything smaller than x - instead of y it could also say z here). 1.
