15342 | Tarski proved that any reasonably expressive language suffers from the liar paradox [Tarski, by Horsten] |

10672 | Tarskian semantics says that a sentence is true iff it is satisfied by every sequence [Tarski, by Hossack] |
15339 | Tarski gave up on the essence of truth, and asked how truth is used, or how it functions [Tarski, by Horsten] |
16302 | Tarski did not just aim at a definition; he also offered an adequacy criterion for any truth definition [Tarski, by Halbach] |

19316 | Insight: don't use truth, use a property which can be compositional in complex quantified sentence [Tarski, by Kirkham] |
19175 | Tarski gave axioms for satisfaction, then derived its explicit definition, which led to defining truth [Tarski, by Davidson] |
16303 | Tarski made truth respectable, by proving that it could be defined [Tarski, by Halbach] |
19134 | Tarski defined truth for particular languages, but didn't define it across languages [Davidson on Tarski] |

20407 | Taste is the capacity to judge an object or representation which is thought to be beautiful [Tarski, by Schellekens] |
18666 | Value-maker concepts (such as courageous or elegant) simultaneously describe and evaluate [Orsi] |
18667 | The '-able' concepts (like enviable) say this thing deserves a particular response [Orsi] |

18677 | A thing may have final value, which is still derived from other values, or from relations [Orsi] |
18668 | Truths about value entail normative truths about actions or attitudes [Orsi] |
