Similarly, Hempel, in his article “Problems and Changes in the Empiricist Criterion of Meaning”discussed verifiabilitty proposal that a sentence has cognitive meaning if and only if it is translatable into an empiricist language. Reprinted in Logic without Metaphysics. Journal of Symbolic Logic 14 Reprinted in Logical Positivismedited by A.

In the case of a basic predicate it may be held that 1 an essential part of the use of the predicate is to identify a property, 2 an ability to use the predicate to identify the relevant property does not constitute knowing its use, unless the user also knows what the ability consists in, and 3 the user cannot be said verifiabjlity know this if it is impossible for him to have any kind verifiabiilty experience of the property in question.

However, in an accepted philosophical usage, every proposition is either true or false, and hence a fortiori a proposition cannot be meaningless. What can or cannot be said of statements applies equally to propositions, except that verifiabioity proposition cannot be meaningless, that is, it cannot be expressed by a meaningless sentence.

Epistemicism, Paradox, and Conditional Obligation. Finally, as we noted before, there is also the problem of explaining what is meant by saying that a basic observation statement is verifiable in principle, that is, that certain experiences are logically possible, if in fact the walsmann in question never occur.

In either case, it is objected, the principle cannot be the decisive criterion of cognitive meaning that its adherents suppose it to be. Lloyd – – Aristotelian Society Supplementary Volume It is evident that if a form of language can be used to describe the world — that is, to make statements — its rules cannot be wholly syntactical, that is, of the kind that govern simply the formation and transformation of sentences in the language.

Similarly, the verifiability principle, which claims to delimit the class of cognitively meaningful statements, cannot be expected to have the same logical status as the statements it delimits.

History of Western Philosophy. The truth of a statement can be defined in terms of its meaning in the following way. For our present purpose it is sufficient to note that it would be a contradiction to say that a language was descriptive but had no semantic rules; similarly, it would be a contradiction for someone to say that he could understand a sentence as expressing a statement although he had not been able to ascertain the semantic rules of the language in which the sentence was expressed.

The fourth criterion is the most liberal and admits into the class of meaningful statements empirical statements of the various kinds that were excluded by the requirement of conclusive verifiability or the requirement of conclusive falsifiability. But “could” here cannot mean “factually could,” since wsismann can speak meaningfully of occurrences that are factually impossible.

Lodder – – Artificial Intelligence and Law 2 2: It is concerned with the fact that one component of the verifiability principle is the thesis that the meaning of a statement is given by its truth conditions.

VERIFIABILITY PRINCIPLE

And finally, if the meaning of a sentence were identified with the experiences of a particular person, the verifiability principle would result in a radical form of solipsism. If a sentence is used to describe an experienceable state of the world, then the semantic rules governing its predicates relate those predicates, directly or indirectly, to that state of the world.

Thus, even in a more qualified version of empiricism the difficulty still remains of making clear what it is to know that a statement is true “by reference to experience.

Find it on Scholar. In order to achieve this result some adherents of the verifiability principle regard certain statements describing physical objects as basic for example, “This is a black telephone” ; others attempt to achieve the same result while still regarding sense-datum or phenomenal statements as basic for example, “Here now a black patch” or “This seems to be a telephone”.

Thus, to revert to the first and main criticism of the verifiability principle, it may be admitted that to ask whether a sentence is meaningful is to ask whether the constituent words are used according to the rules of a language. It has also been thought to be of importance for the criterion of weak verifiability or confirmability, for, it has been said, unless basic statements are certain, or in some sense incorrigible, no other statement can be even probable or confirmable.

The verifiability principle stands historically in a line of direct descent from the empiricism of David HumeJ.

These requirements are, perhaps, all that is essential in the claim made by the verifiability principle in its later formulations. Review of Ayer’s Language, Truth and Logic2nd ed. Request removal from index. No keywords specified fix it.

Charles A. Baylis, Review: Friedrich Waismann, Verifiability (Part II of a Symposium) – PhilPapers

The earliest presentations of the verifiability principle identified the meaning of a sentence with the logical possibility of verifying the corresponding statement, and apparently, in the last analysis, with the occurrence of certain experiences.

Carnap and Ayer, among others, have taken this view of the status of the verifiability principle. Cognitive Meaning and Cognitive Use. Logic and Verifianility of Logic. Evans in “On Meaning and Verification. Sign in to use this feature.

The verifiability principle is an attempt to answer the question “Under what conditions is a sentence cognitively or factually meaningful? This idea, which may be called “the truth theory of meaning,” had been employed and stated by philosophers before the discussions of the Vienna circle.

To meet objections of this kind Ayer introduces a number of conditions; he says 1 “a statement is directly verifiable if it is either verifiaability an observation-statement, or is such that in conjunction with one or more observation-statements it entails at least one observation-statement which is not deducible from these other premises alone,” and 2 “a statement is indirectly verifiable if it veridiability the following conditions:
