And we need to understand what it is that renders the one legitimate, but not the other. For example, the 23 H. Stipulative definitions are epistemologically special. In application to ordinary, informal definitions, the Vicious-Circle Principle does not provide, it must be said, a clear method of demarcating the meaningful from the meaningless. The orthodox view is to rule such definitions as illegitimate, but the orthodoxy deserves to be challenged here. Finally, a term can be introduced by a stipulative definition into a ground language whose logical resources are confined, say, to classical conjunction and disjunction. This idea, when conjoined with the primacy of the sentential, leads to a strong version of the Use criterion, called the Eliminability criterion: the definition must reduce each formula containing the defined term to a formula in the ground language, i.

For a proof of the theorem, see Boolos, Burgess, and Jeffrey 2002; see also Beth 1953. Folklore credits the Polish logician S. And, for that matter, the definiendum? Horty 2007 offers some ways of thinking about senses of defined expressions, especially within a Fregean semantic theory. If propositions are sets of possible worlds, for example, then such a definition would appear to be feasible. Sentences containing defined terms are subject to the same logical laws as sentences of the ground language.

It is useful to distinguish three grades of descriptive adequacy of a definition: extensional, intensional, and sense. Nonetheless, it is noteworthy because it illustrates how general issues about meaning and concepts enter the debate on the requirements on legitimate definitions. The result is that we have a hierarchy of propositions and of concepts of various orders. There are complications here, however. And it is this kind of definition that will be our primary concern.

The only requirements that it imposes are i that the definiendum contain the defined term; ii that the definiendum and the definiens belong to the same logical category; and iii the definition satisfies Conservativeness and Eliminability. Different dictionaries can give different bits of information and yet be equally effective in explaining the meanings of terms. If this is right then a predicate is meaningfulâit expresses a conceptâonly if the predicate necessarily demarcates the world sharply into those objects to which it applies and those to which it does not apply. Observe that the satisfaction of Conservativeness and Eliminability criteria, whether in their semantic or their syntactic formulation, is not an absolute property of a definition; the satisfaction is relative to the ground language. This is a person that is beautiful inside and out.

The logic and semantics of definitions in non-classical logics receive, under the traditional account, a parallel treatment. This is perfectly legitimate, according to the traditional account, because a theorem of Peano Arithmetic establishes that the above definition is equivalent to one in normal form. An ostensive definitions can also be explicative. This question must be answered positively if implicit definitions are to serve their philosophical function. Moreover, if such definitions were abbreviations, they would be subject to the requirement that the definiendum must be shorter than the definiens, but no such requirement exists.

Mays tend to be a little shy when you first meet them, but when you get to know them they are the and exciting people you would ever meet. Some of the issues are the following. Ostensive definitions typically depend on context and on experience. Revision processes help provide a semantics for circular definitions. The question remains whether the meanings thus endowed are identical to or similar enough to the meanings the theoretical terms have in their actual uses in physics. The objection is plainly not decisive, for it rests on a premiss that rules out many ordinary and apparently meaningful predicates e.

Now, if a philosophical application requires some violations of Conservativeness to be legitimate, we need an account of the distinction between the two sorts of cases: the legitimate violations of Conservativeness and the non-legitimate ones. Hence, the objection concludes, no predicate with an essentially circular definition can be meaningful. But what is the source of the difference? The traditional account of definitions is founded on three ideas. The precise characterization of the non-observational component can vary with the specific epistemological problem at hand. This failure has two sources. Definitions sought by philosophers are not of the sort found in a dictionary. When philosophers offer definitions of, e.

Multiple definitions bring notational complexity but raise no new conceptual issues. The aim of invoking implicit definitions is to account for the rationality, or the aprioricity, or the analyticity of our ordinary judgments, not of some extraordinary judgments that are somehow assigned to ordinary signs. If this is correct, then there is no logical requirement on descriptive and explicative definitions that they be non-circular. This strong parallelism suggests that since truth is manifestly a legitimate concept, so also are concepts defined by circular definitions such as 18. The syntactic and semantic formulations of the two criteria are plainly parallel. Let us leave the challenge to another occasion, however, and proceed to bypass the complications through idealization.

May tends to be shy when you first meet her but when you get to know her, she starts showing her! This idea is easily accommodated within the traditional account. The traditional account of definitions should not be viewed as requiring definitions to be in normal form. Dictionaries aim to provide definitions that contain sufficient information to impart an understanding of the term. The first idea is that definitions are generalized identities; the second, that the sentential is primary; and the third, that of reduction. There is a view that using can to ask for permission is wrong and that it should only be used in to do with ability or , e. The normal form of definitions can be specified as follows.

The issues the second idea raises are, of course, large and important, but they cannot be addressed in a brief survey. In contrast, in a modal logic that requires names to be non-vacuous and rigid, the specific condition would be strengthened: not only must existence and uniqueness be shown to hold necessarily, it must be shown that the definiens is satisfied by one and the same object across possible worlds. Used in granting permission and in questions to make polite requests. Russell argued that such definitions involve a subtle kind of vicious circle.
