indefinability

The indefinability of the human mind is the theme of the film.

Its indefinability freed it from the rules of metaphysics.

Moore has a famous argument in favour of the simplicity and indefinability of good.

Socrates admits its indefinability and explains its nature by the analogy of the sun.

Unquantifiability, and undefinability (or indefinability), can also sometimes be synonymous with indeterminacy.

Tarski's indefinability theorem shows that this theory is not arithmetically definable.

The central result on true arithmetic is the indefinability theorem of Alfred Tarski (1936).

This is closely related to Tarski's indefinability theorem.

The radical indefinability of the key terms suggests a difficulty with such a schema, and it was a difficulty for Stevenson as well.

In particular, Gödel was aware of the result now called Tarski's indefinability theorem, although he never published it.

Tarski's indefinability theorem shows that the set of true formulas of first order arithmetic is not arithmetically definable.

Moore advanced an argument for the indefinability of "good" (and demonstrating the "naturalistic fallacy") which is known as the Open Question Argument.

Similarly, Tarski's indefinability theorem can be interpreted both in terms of definability and in terms of computability.

A vastly influential work, its insistence on the indefinability of "good" and its exposition of the so-called naturalistic fallacy were long regarded as path-breaking advances in moral philosophy.

The sentences whose existence is secured by the diagonal lemma can then, in turn, be used to prove fundamental limitative results such as Gödel's incompleteness theorems and Tarski's indefinability theorem.

The set T is Turing equivalent to the set , and so is not high in the hyperarithmetical hierarchy, although it is not arithmetically definable by Tarski's indefinability theorem.

Moore's argument for the indefinability of "good" (and thus for the fallaciousness of the "naturalistic fallacy") is often called the open-question argument; it is presented in 13 of Principia Ethica.

Reed is among the most American of American writers, if by "American" we mean a quality defined by its indefinability and its perpetual transformations as new ideas, influences and traditions enter our cultural conversation.

The fact that such self-reference can be expressed within arithmetic was not known until Gödel's paper appeared; independent work of Alfred Tarski on his indefinability theorem was conducted around the same time but not published until 1936.

The last chapter, on Gödel's incompleteness theorem and Tarski's indefinability theorem, along with the article Quine (1946), became a launching point for Raymond Smullyan's later lucid exposition of these and related results.

Yet he cited as causes, in a 1906 manuscript, his differences with James and Schiller and, in a 1908 publication, his differences with James as well as literary author Giovanni Papini's declaration of pragmatism's indefinability.

This is music of such diverse, often ambiguous or ambivalent character - varying widely not only from work to work but frequently from bar to bar - that the very diversity and indefinability of tone has to be considered a fundamental quality of the experience.

Moore would surely grant that there is an indefinability of the word which follows from the fact that what it labels is indefinable, while those who treat it as a statement about a word see it as turning upon what the word is supposed to stand for.
