Christopher Peacocke on Necessity - Dictionary of Arguments
II 313 Necessity/necessary/modification of predicates/Wiggins/Peacocke: Problem: 'big' cannot modify like 'nec' predicates of any fine degree. ((s) "nec" : Operator for necessary"). >Operators. That means, we get a finite axiomatized theory for 'big' but not for 'nec'. - There can only be an infinite number of modifications here. >Axioms, >Axiom systems, >Axiomatizability. Problem: 'nec' can be iterated in the object language, but Grandy's representational content cannot treat the iterations because the performance is not defined. Solution: 1. syntactical variabel 't>' is about series of terms of the form (t1 ... tn) 2. separate recursion for abstracts of the object language in the theory, that specifies inductively the conditions under which a sequence has the property correlated with the abstract('Corr'). II 316 Then the truth conditions turn the predications into sequences - so the theory is not entirely homophonic. >Homophony, >Truth conditions, >Predication. II 324 Necessity/satisfaction/language/Peacocke: the satisfaction and evaluation axioms not only express contingent truths about the language - necessarily in German each sequence fulfils x1 'is greater than Hesperus' in L, if their first element is greater than Hesperus. >Satisfaction._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
