Meaning and Truth
- 2.1 Meaning
The empiricist basis of Ayer’s attitude to meaning was laid first inhis reading of Hume. The thought that no idea had any empiricalsignificance unless it was suitably related to an impression stayedwith him, and was reinforced both by his reading of Wittgenstein’sTractatus and by the ti… - 2.2 Truth
In LTL Ayer, following Ramsey (as he thought, but see Field1986 for a dissenting view), put forward a redundancy (deflationary)view of truth: “…in all sentences of the form‘p is true’, the phrase ‘is true’ islogically superfluous” (LTLp. 117). The function ofsuch a phrase is simply to m…
Perception
- In his early work on perception Ayer espoused a strict form ofphenomenalism, defending the view that statements about materialobjects are translatable into statements about actual and possible‘sense-contents’. These latter statements were theultimate verifiers, forming the basis upon which our empirical worldwas constructed. Although he later abandoned the reductionism …
Induction and Probability
- Hume was an influential figure in the formation of Ayer’sphilosophical views, so it is no surprise to find Ayer’s approach toinductive inference modeled on Hume’s. Ayer defined inductiveinference in negative terms, as involving all factual inference inwhich the premises did not entail the conclusion. All such inferences,Ayer claimed, presumed the uniformity of nature, an assumption …
Necessity, Causality, and Freedom
- We have seen that in LTLAyer maintained that all necessarytruths were true in virtue of the meanings of the terms used inexpressing them, this in turn depending on the conventions governingthe use of those terms. One can see in the expression of this earlyview unease about the source of logical necessity. He describes thenecessity of logical truths as dependent on the …
Ethics
- The emotivism espoused by Ayer in LTL was supported by hisbelief in the distinction between fact and value. Given, he thought,that there were no moral facts to be known, there could be noverification of such facts, and so moral utterances could have nocognitive significance. And given the connection between moral‘judgment’ and motivation, and the connection betweenmoti…
