5750 | Consistency is modal, saying propositions are consistent if they could be true together [Melia] |
5737 | Predicate logic has connectives, quantifiers, variables, predicates, equality, names and brackets [Melia] |
5744 | First-order predicate calculus is extensional logic, but quantified modal logic is intensional (hence dubious) [Melia] |
5740 | Second-order logic needs second-order variables and quantification into predicate position [Melia] |
5741 | If every model that makes premises true also makes conclusion true, the argument is valid [Melia] |
14562 | A process is unified as an expression of a collection of causal powers [Mumford/Anjum] |
14541 | Events are essentially changes; property exemplifications are just states of affairs [Mumford/Anjum] |
5735 | Maybe names and predicates can capture any fact [Melia] |
5736 | No sort of plain language or levels of logic can express modal facts properly [Melia] |
15538 | Semantic indecision explains vagueness (if we have precisifications to be undecided about) [Lewis] |
14553 | Weak emergence is just unexpected, and strong emergence is beyond all deduction [Mumford/Anjum] |
14538 | Powers explain properties, causes, modality, events, and perhaps even particulars [Mumford/Anjum] |
14555 | Powers offer no more explanation of nature than laws do [Mumford/Anjum] |
14557 | Powers are not just basic forces, since they combine to make new powers [Mumford/Anjum] |
14583 | Dispositionality is a natural selection function, picking outcomes from the range of possibilities [Mumford/Anjum] |
14536 | We say 'power' and 'disposition' are equivalent, but some say dispositions are manifestable [Mumford/Anjum] |
14584 | The simple conditional analysis of dispositions doesn't allow for possible prevention [Mumford/Anjum] |
14582 | Might dispositions be reduced to normativity, or to intentionality? [Mumford/Anjum] |
15537 | If cats are vague, we deny that the many cats are one, or deny that the one cat is many [Lewis] |
14542 | If statue and clay fall and crush someone, the event is not overdetermined [Mumford/Anjum] |
15536 | We have one cloud, but many possible boundaries and aggregates for it [Lewis] |
14535 | Pandispositionalists say structures are clusters of causal powers [Mumford/Anjum] |
14561 | Perdurantism imposes no order on temporal parts, so sequences of events are contingent [Mumford/Anjum] |
5746 | The Identity of Indiscernibles is contentious for qualities, and trivial for non-qualities [Melia] |
14579 | Dispositionality is the core modality, with possibility and necessity as its extreme cases [Mumford/Anjum] |
14580 | Dispositions may suggest modality to us - as what might not have been, and what could have been [Mumford/Anjum] |
5738 | We may be sure that P is necessary, but is it necessarily necessary? [Melia] |
5732 | 'De re' modality is about things themselves, 'de dicto' modality is about propositions [Melia] |
14552 | Relations are naturally necessary when they are generated by the essential mechanisms of the world [Mumford/Anjum] |
14578 | Possibility might be non-contradiction, or recombinations of the actual, or truth in possible worlds [Mumford/Anjum] |
5739 | Sometimes we want to specify in what ways a thing is possible [Melia] |
14549 | Maybe truths are necessitated by the facts which are their truthmakers [Mumford/Anjum] |
5734 | Possible worlds make it possible to define necessity and counterfactuals without new primitives [Melia] |
5742 | In possible worlds semantics the modal operators are treated as quantifiers [Melia] |
5743 | If possible worlds semantics is not realist about possible worlds, logic becomes merely formal [Melia] |
5749 | Possible worlds could be real as mathematics, propositions, properties, or like books [Melia] |
5751 | The truth of propositions at possible worlds are implied by the world, just as in books [Melia] |
14585 | We have more than five senses; balance and proprioception, for example [Mumford/Anjum] |
14576 | Smoking disposes towards cancer; smokers without cancer do not falsify this claim [Mumford/Anjum] |
14551 | If causation were necessary, the past would fix the future, and induction would be simple [Mumford/Anjum] |
14571 | The only full uniformities in nature occur from the essences of fundamental things [Mumford/Anjum] |
14570 | Nature is not completely uniform, and some regular causes sometimes fail to produce their effects [Mumford/Anjum] |
14569 | It is tempting to think that only entailment provides a full explanation [Mumford/Anjum] |
14568 | A structure won't give a causal explanation unless we know the powers of the structure [Mumford/Anjum] |
14556 | Strong emergence seems to imply top-down causation, originating in consciousness [Mumford/Anjum] |
5748 | We accept unverifiable propositions because of simplicity, utility, explanation and plausibility [Melia] |
15539 | Basic to pragmatics is taking a message in a way that makes sense of it [Lewis] |
14566 | Causation by absence is not real causation, but part of our explanatory practices [Mumford/Anjum] |
14577 | Causation may not be transitive. Does a fire cause itself to be extinguished by the sprinklers? [Mumford/Anjum] |
14563 | Causation is the passing around of powers [Mumford/Anjum] |
14587 | We take causation to be primitive, as it is hard to see how it could be further reduced [Mumford/Anjum] |
14533 | Causation doesn't have two distinct relata; it is a single unfolding process [Mumford/Anjum] |
14558 | A collision is a process, which involves simultaneous happenings, but not instantaneous ones [Mumford/Anjum] |
14559 | Does causation need a third tying ingredient, or just two that meet, or might there be a single process? [Mumford/Anjum] |
14565 | Sugar dissolving is a process taking time, not one event and then another [Mumford/Anjum] |
14567 | Privileging one cause is just an epistemic or pragmatic matter, not an ontological one [Mumford/Anjum] |
14537 | Coincidence is conjunction without causation; smoking causing cancer is the reverse [Mumford/Anjum] |
14573 | Occasionally a cause makes no difference (pre-emption, perhaps) so the counterfactual is false [Mumford/Anjum] |
14572 | Is a cause because of counterfactual dependence, or is the dependence because there is a cause? [Mumford/Anjum] |
14574 | Cases of preventing a prevention may give counterfactual dependence without causation [Mumford/Anjum] |
14539 | Nature can be interfered with, so a cause never necessitates its effects [Mumford/Anjum] |
14550 | We assert causes without asserting that they necessitate their effects [Mumford/Anjum] |
14546 | Necessary causation should survive antecedent strengthening, but no cause can always survive that [Mumford/Anjum] |
14575 | A 'ceteris paribus' clause implies that a conditional only has dispositional force [Mumford/Anjum] |
14548 | There may be necessitation in the world, but causation does not supply it [Mumford/Anjum] |
14554 | Laws are nothing more than descriptions of the behaviour of powers [Mumford/Anjum] |
14564 | If laws are equations, cause and effect must be simultaneous (or the law would be falsified)! [Mumford/Anjum] |
