17325 | Truth-maker theory can't cope with non-causal dependence [Liggins] |
17318 | Truthmakers for existence is fine; otherwise maybe restrict it to synthetic truths? [Liggins] |
15879 | The Square of Opposition has two contradictory pairs, one contrary pair, and one sub-contrary pair [Harré] |
15891 | Traditional quantifiers combine ordinary language generality and ontology assumptions [Harré] |
14232 | We normally formalise 'There are Fs' with singular quantification and predication, but this may be wrong [Liggins] |
15878 | Some quantifiers, such as 'any', rule out any notion of order within their range [Harré] |
17320 | Either p is true or not-p is true, so something is true, so something exists [Liggins] |
17326 | The dependence of {Socrates} on Socrates involves a set and a philosopher, not facts [Liggins] |
17327 | Non-causal dependence is at present only dimly understood [Liggins] |
17322 | Necessities supervene on everything, but don't depend on everything [Liggins] |
15874 | Scientific properties are not observed qualities, but the dispositions which create them [Harré] |
594 | Speusippus suggested underlying principles for every substance, and ended with a huge list [Speussipus, by Aristotle] |
14233 | Nihilists needn't deny parts - they can just say that some of the xs are among the ys [Liggins] |
15884 | Laws of nature remain the same through any conditions, if the underlying mechanisms are unchanged [Harré] |
15880 | In physical sciences particular observations are ordered, but in biology only the classes are ordered [Harré] |
15869 | Reports of experiments eliminate the experimenter, and present results as the behaviour of nature [Harré] |
15881 | We can save laws from counter-instances by treating the latter as analytic definitions [Harré] |
15882 | Since there are three different dimensions for generalising laws, no one system of logic can cover them [Harré] |
15888 | The grue problem shows that natural kinds are central to science [Harré] |
15887 | 'Grue' introduces a new causal hypothesis - that emeralds can change colour [Harré] |
15889 | It is because ravens are birds that their species and their colour might be connected [Harré] |
15890 | Non-black non-ravens just aren't part of the presuppositions of 'all ravens are black' [Harré] |
17324 | 'Because' can signal an inference rather than an explanation [Liggins] |
17321 | Value, constitution and realisation are non-causal dependences that explain [Liggins] |
17323 | If explanations track dependence, then 'determinative' explanations seem to exist [Liggins] |
15885 | The necessity of Newton's First Law derives from the nature of material things, not from a mechanism [Harré] |
15868 | Idealisation idealises all of a thing's properties, but abstraction leaves some of them out [Harré] |
15886 | Science rests on the principle that nature is a hierarchy of natural kinds [Harré] |
15864 | Classification is just as important as laws in natural science [Harré] |
15865 | Newton's First Law cannot be demonstrated experimentally, as that needs absence of external forces [Harré] |
15862 | Laws can come from data, from theory, from imagination and concepts, or from procedures [Harré] |
15870 | Are laws of nature about events, or types and universals, or dispositions, or all three? [Harré] |
15871 | Are laws about what has or might happen, or do they also cover all the possibilities? [Harré] |
15876 | Maybe laws of nature are just relations between properties? [Harré] |
15860 | We take it that only necessary happenings could be laws [Harré] |
15872 | Must laws of nature be universal, or could they be local? [Harré] |
15867 | Laws describe abstract idealisations, not the actual mess of nature [Harré] |
15892 | Laws of nature state necessary connections of things, events and properties, based on models of mechanisms [Harré] |
15875 | In counterfactuals we keep substances constant, and imagine new situations for them [Harré] |
2632 | Speusippus said things were governed by some animal force rather than the gods [Speussipus, by Cicero] |
