19193 | Disputes that fail to use precise scientific terminology are all meaningless [Tarski] |
23945 | Reason is actually passions, guided by perspicacious reflection [Solomon] |
19179 | For a definition we need the words or concepts used, the rules, and the structure of the language [Tarski] |
19178 | Definitions of truth should not introduce a new version of the concept, but capture the old one [Tarski] |
19177 | A definition of truth should be materially adequate and formally correct [Tarski] |
19186 | A rigorous definition of truth is only possible in an exactly specified language [Tarski] |
19194 | We may eventually need to split the word 'true' into several less ambiguous terms [Tarski] |
19180 | It is convenient to attach 'true' to sentences, and hence the language must be specified [Tarski] |
19181 | In the classical concept of truth, 'snow is white' is true if snow is white [Tarski] |
19196 | Scheme (T) is not a definition of truth [Tarski] |
19183 | Each interpreted T-sentence is a partial definition of truth; the whole definition is their conjunction [Tarski] |
19182 | Use 'true' so that all T-sentences can be asserted, and the definition will then be 'adequate' [Tarski] |

19195 | Truth tables give prior conditions for logic, but are outside the system, and not definitions [Tarski] |
19192 | The truth definition proves semantic contradiction and excluded middle laws (not the logic laws) [Tarski] |
19187 | The Liar makes us assert a false sentence, so it must be taken seriously [Tarski] |
23957 | We often trust our intuitions as rational, despite their lack of reflection [Solomon] |
23943 | Distinguishing reason from passion is based on an archaic 'faculty' theory [Solomon] |

23954 | Emotions are judgements about ourselves, and our place in the world [Solomon] |
