5196 | Philosophy is a department of logic [Ayer] |
5189 | Philosophers should abandon speculation, as philosophy is wholly critical [Ayer] |
7919 | Humeans rejected the a priori synthetic, and so rejected even Kantian metaphysics [Ayer, by Macdonald,C] |
5195 | Critics say analysis can only show the parts, and not their distinctive configuration [Ayer] |

19151 | Antirealism about truth prevents its use as an intersubjective standard [Davidson] |
19144 | 'Epistemic' truth depends what rational creatures can verify [Davidson] |
19148 | There is nothing interesting or instructive for truths to correspond to [Davidson] |
19167 | Two sentences can be rephrased by equivalent substitutions to correspond to the same thing [Davidson] |
19166 | The Slingshot assumes substitutions give logical equivalence, and thus identical correspondence [Davidson] |
19150 | Coherence truth says a consistent set of sentences is true - which ties truth to belief [Davidson] |
19146 | Satisfaction is a sort of reference, so maybe we can define truth in terms of reference? [Davidson] |
19145 | We can explain truth in terms of satisfaction - but also explain satisfaction in terms of truth [Davidson] |
19174 | Axioms spell out sentence satisfaction. With no free variables, all sequences satisfy the truths [Davidson] |
19172 | To define a class of true sentences is to stipulate a possible language [Davidson] |
19136 | Many say that Tarski's definitions fail to connect truth to meaning [Davidson] |
19139 | Tarski does not tell us what his various truth predicates have in common [Davidson] |
19147 | Truth is the basic concept, because Convention-T is agreed to fix the truths of a language [Davidson] |
19153 | Truth is basic and clear, so don't try to replace it with something simpler [Davidson] |
4749 | We cannot analyse the concept of 'truth', because it is simply a mark that a sentence is asserted [Ayer] |

5202 | Maths and logic are true universally because they are analytic or tautological [Ayer] |
6523 | Positivists regard ontology as either meaningless or stipulated [Ayer, by Robinson,H] |
19173 | Treating predicates as sets drops the predicate for a new predicate 'is a member of', which is no help [Davidson] |
19142 | Probability can be constrained by axioms, but that leaves open its truth nature [Davidson] |
5183 | Only tautologies can be certain; other propositions can only be probable [Ayer] |
6525 | Logical positivists could never give the sense-data equivalent of 'there is a table next door' [Robinson,H on Ayer] |
5170 | Material things are constructions from actual and possible occurrences of sense-contents [Ayer] |
5198 | We could verify 'a thing can't be in two places at once' by destroying one of the things [Ierubino on Ayer] |
2619 | Whether geometry can be applied to reality is an empirical question outside of geometry [Ayer] |
5197 | By changing definitions we could make 'a thing can't be in two places at once' a contradiction [Ayer] |
5204 | To say that a proposition is true a priori is to say that it is a tautology [Ayer] |
6524 | Positivists prefer sense-data to objects, because the vocabulary covers both illusions and perceptions [Ayer, by Robinson,H] |

5180 | All propositions (especially 'metaphysics') must begin with the senses [Ayer] |
5169 | My empiricism logically distinguishes analytic and synthetic propositions, and metaphysical verbiage [Ayer] |
5185 | It is further sense-experience which informs us of the mistakes that arise out of sense-experience [Ayer] |
5199 | Empiricism, it is said, cannot account for our knowledge of necessary truths [Ayer] |
5190 | The induction problem is to prove generalisations about the future based on the past [Ayer] |
5191 | We can't use the uniformity of nature to prove induction, as that would be circular [Ayer] |
5177 | Other minds are 'metaphysical' objects, because I can never observe their experiences [Ayer] |
5178 | A conscious object is by definition one that behaves in a certain way, so behaviour proves consciousness [Ayer] |
19169 | Predicates are a source of generality in sentences [Davidson] |
5172 | If the self is meaningful, it must be constructed from sense-experiences [Ayer] |
5173 | Two experiences belong to one self if their contents belong with one body [Ayer] |
5176 | Empiricists can define personal identity as bodily identity, which consists of sense-contents [Ayer] |
5171 | The supposed 'gulf' between mind and matter is based on the senseless concept of 'substances' [Ayer] |
19149 | If we reject corresponding 'facts', we should also give up the linked idea of 'representations' [Davidson] |
19163 | You only understand an order if you know what it is to obey it [Davidson] |
19152 | Utterances have the truth conditions intended by the speaker [Davidson] |
5181 | A sentence is factually significant to someone if they know how to verify its proposition [Ayer] |
5184 | Factual propositions imply (in conjunction with a few other premises) possible experiences [Ayer] |
5186 | Tautologies and empirical hypotheses form the entire class of significant propositions [Ayer] |
19162 | Meaning involves use, but a sentence has many uses, while meaning stays fixed [Davidson] |
19131 | We recognise sentences at once as linguistic units; we then figure out their parts [Davidson] |
19176 | The concept of truth can explain predication [Davidson] |
19156 | Modern predicates have 'places', and are sentences with singular terms deleted from the places [Davidson] |
19133 | If you assign semantics to sentence parts, the sentence fails to compose a whole [Davidson] |
19132 | Top-down semantic analysis must begin with truth, as it is obvious, and explains linguistic usage [Davidson] |
19158 | 'Humanity belongs to Socrates' is about humanity, so it's a different proposition from 'Socrates is human' [Davidson] |
19154 | The principle of charity says an interpreter must assume the logical constants [Davidson] |
19161 | We indicate use of a metaphor by its obvious falseness, or trivial truth [Davidson] |
468 | Musical performance can reveal a range of virtues [Damon of Ath.] |
5205 | Moral intuition is worthless if there is no criterion to decide between intuitions [Ayer] |
23725 | Ayer defends the emotivist version of expressivism [Ayer, by Smith,M] |

5187 | When we ascribe an attribute to a thing, we covertly assert that it exists [Ayer] |
5207 | If theism is non-sensical, then so is atheism. [Ayer] |
