6961 | An analogy begins to break down as soon as the two cases differ [Hume] |
18486 | We might define truth as arising from the truth-maker relation [MacBride] |
18484 | Phenomenalists, behaviourists and presentists can't supply credible truth-makers [MacBride] |
18466 | If truthmaking is classical entailment, then anything whatsoever makes a necessary truth [MacBride] |
18473 | 'Maximalism' says every truth has an actual truthmaker [MacBride] |
18481 | Maximalism follows Russell, and optimalism (no negative or universal truthmakers) follows Wittgenstein [MacBride] |
18483 | The main idea of truth-making is that what a proposition is about is what matters [MacBride] |
18479 | There are different types of truthmakers for different types of negative truth [MacBride] |
18477 | There aren't enough positive states out there to support all the negative truths [MacBride] |
18482 | Optimalists say that negative and universal are true 'by default' from the positive truths [MacBride] |
18474 | Does 'this sentence has no truth-maker' have a truth-maker? Reductio suggests it can't have [MacBride] |
18485 | Even idealists could accept truthmakers, as mind-dependent [MacBride] |
18490 | Maybe 'makes true' is not an active verb, but just a formal connective like 'because'? [MacBride] |
18493 | Truthmaker talk of 'something' making sentences true, which presupposes objectual quantification [MacBride] |
10170 | While true-in-a-model seems relative, true-in-all-models seems not to be [Reck/Price] |
10166 | ZFC set theory has only 'pure' sets, without 'urelements' [Reck/Price] |
18489 | Connectives link sentences without linking their meanings [MacBride] |
18476 | 'A is F' may not be positive ('is dead'), and 'A is not-F' may not be negative ('is not blind') [MacBride] |
10175 | Three types of variable in second-order logic, for objects, functions, and predicates/sets [Reck/Price] |
10165 | 'Analysis' is the theory of the real numbers [Reck/Price] |
10174 | Mereological arithmetic needs infinite objects, and function definitions [Reck/Price] |
10164 | Peano Arithmetic can have three second-order axioms, plus '1' and 'successor' [Reck/Price] |
10172 | Set-theory gives a unified and an explicit basis for mathematics [Reck/Price] |
10167 | Structuralism emerged from abstract algebra, axioms, and set theory and its structures [Reck/Price] |
10169 | Relativist Structuralism just stipulates one successful model as its arithmetic [Reck/Price] |
10179 | There are 'particular' structures, and 'universal' structures (what the former have in common) [Reck/Price] |
10181 | Pattern Structuralism studies what isomorphic arithmetic models have in common [Reck/Price] |
10182 | There are Formalist, Relativist, Universalist and Pattern structuralism [Reck/Price] |
10168 | Formalist Structuralism says the ontology is vacuous, or formal, or inference relations [Reck/Price] |
10178 | Maybe we should talk of an infinity of 'possible' objects, to avoid arithmetic being vacuous [Reck/Price] |
10176 | Universalist Structuralism is based on generalised if-then claims, not one particular model [Reck/Price] |
10177 | Universalist Structuralism eliminates the base element, as a variable, which is then quantified out [Reck/Price] |
10171 | The existence of an infinite set is assumed by Relativist Structuralism [Reck/Price] |
18480 | Maybe it only exists if it is a truthmaker (rather than the value of a variable)? [MacBride] |
18471 | Different types of 'grounding' seem to have no more than a family resemblance relation [MacBride] |
18472 | Which has priority - 'grounding' or 'truth-making'? [MacBride] |
18475 | Russell allows some complex facts, but Wittgenstein only allows atomic facts [MacBride] |
10173 | A nominalist might avoid abstract objects by just appealing to mereological sums [Reck/Price] |
18478 | Wittgenstein's plan to show there is only logical necessity failed, because of colours [MacBride] |
21285 | Events are baffling before experience, and obvious after experience [Hume] |
6959 | We can't assume God's perfections are like our ideas or like human attributes [Hume] |
6957 | The objects of theological reasoning are too big for our minds [Hume] |
21255 | No being's non-existence can imply a contradiction, so its existence cannot be proved a priori [Hume] |
21254 | A chain of events requires a cause for the whole as well as the parts, yet the chain is just a sum of parts [Hume] |
1435 | If something must be necessary so that something exists rather than nothing, why can't the universe be necessary? [Hume] |
6962 | The thing which contains order must be God, so see God where you see order [Hume] |
6964 | From our limited view, we cannot tell if the universe is faulty [Hume] |
21279 | If the divine cause is proportional to its effects, the effects are finite, so the Deity cannot be infinite [Hume] |
6958 | How can we pronounce on a whole after a brief look at a very small part? [Hume] |
6963 | Why would we infer an infinite creator from a finite creation? [Hume] |
21282 | Design cannot prove a unified Deity. Many men make a city, so why not many gods for a world? [Hume] |
21280 | From a ship you would judge its creator a genius, not a mere humble workman [Hume] |
21281 | This excellent world may be the result of a huge sequence of trial-and-error [Hume] |
21283 | Humans renew their species sexually. If there are many gods, would they not do the same? [Hume] |
6966 | Creation is more like vegetation than human art, so it won't come from reason [Hume] |
21284 | This Creator god might be an infant or incompetent or senile [Hume] |
21286 | Motion often begins in matter, with no sign of a controlling agent [Hume] |
21287 | The universe could settle into superficial order, without a designer [Hume] |
21288 | Ideas arise from objects, not vice versa; ideas only influence matter if they are linked [Hume] |
21256 | A surprise feature of all products of 9 looks like design, but is actually a necessity [Hume] |
6960 | Analogy suggests that God has a very great human mind [Hume] |
6965 | The universe may be the result of trial-and-error [Hume] |
6967 | Order may come from an irrational source as well as a rational one [Hume] |
