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] |

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] |

18472 | Which has priority - 'grounding' or 'truth-making'? [MacBride] |
18475 | Russell allows some complex facts, but Wittgenstein only allows atomic facts [MacBride] |
21354 | It may be that internal relations like proportion exist, because we directly perceive it [MacBride] |

22902 | Why does an effect require a prior event if the prior event isn't a cause? [Bardon] |
22905 | Becoming disordered is much easier for a system than becoming ordered [Bardon] |
22913 | The universe expands, so space-time is enlarging [Bardon] |
22889 | We should treat time as adverbial, so we don't experience time, we experience things temporally [Bardon, by Bardon] |
22900 | How can we question the passage of time, if the question takes time to ask? [Bardon] |
22898 | What is time's passage relative to, and how fast does it pass? [Bardon] |
22897 | The A-series says a past event is becoming more past, but how can it do that? [Bardon] |
22901 | The B-series needs a revised view of causes, laws and explanations [Bardon] |
22896 | The B-series is realist about time, but idealist about its passage [Bardon] |
22903 | The B-series adds directionality when it accepts 'earlier' and 'later' [Bardon] |
22910 | To define time's arrow by causation, we need a timeless definition of causation [Bardon] |
22909 | We judge memories to be of the past because the events cause the memories [Bardon] |
22904 | The psychological arrow of time is the direction from our memories to our anticipations [Bardon] |
22906 | The direction of entropy is probabilistic, not necessary, so cannot be identical to time's arrow [Bardon] |
22907 | It is arbitrary to reverse time in a more orderly universe, but not in a sub-system of it [Bardon] |
22883 | It seems hard to understand change without understanding time first [Bardon] |
22890 | We experience static states (while walking round a house) and observe change (ship leaving dock) [Bardon] |
22884 | The motion of a thing should be a fact in the present moment [Bardon] |
