| 18351 | Propositions are made true, in virtue of something which explains its truth [Lowe] |
| Full Idea: If a proposition is 'made' true, it has to be true 'in virtue of' something, meaning a relationship of metaphysical explanation. Thus a true proposition must have truth conferred on it in some way that explains how it gets to be true. | |
| From: E.J. Lowe (An essentialist approach to Truth-making [2009], p.202) | |
| A reaction: It is good to ask what we mean by 'makes'. I like essentialist explanations, but this may be misplaced. Observing that y makes x true seems to be rather less than actually explaining how it does it. What would such explanations look like? |
| 8942 | Lukasiewicz's L3 logic has three truth-values, T, F and I (for 'indeterminate') [Lukasiewicz, by Fisher] |
| Full Idea: In response to Aristotle's sea-battle problem, Lukasiewicz proposed a three-valued logic that has come to be known as L3. In addition to the values true and false (T and F), there is a third truth-value, I, meaning 'indeterminate' or 'possible'. | |
| From: report of Jan Lukasiewicz (Elements of Mathematical Logic [1928], 7.I) by Jennifer Fisher - On the Philosophy of Logic | |
| A reaction: [He originated the idea in 1917] In what sense is the third value a 'truth' value? Is 'I don't care' a truth-value? Or 'none of the above'? His idea means that formalization doesn't collapse when things get obscure. You park a few propositions under I. |
| 18353 | Modes are beings that are related both to substances and to universals [Lowe] |
| Full Idea: Modes are real beings that stand in non-contingent formal ontological relations both to individual substances and to immanent universals. | |
| From: E.J. Lowe (An essentialist approach to Truth-making [2009], p.212) | |
| A reaction: Not sure I understand this, but I pass it on. 'Modes' seem to invite the Razor, if we already have substances and universals. I am no clear about 'instantiation' because I now have the word 'mode' to play with. |
| 18352 | Tropes have existence independently of any entities [Lowe] |
| Full Idea: Pure trope theorists must apparently hold that each trope has its identity underivatively, not that it depends for it on or owes it to other entities of any sort. | |
| From: E.J. Lowe (An essentialist approach to Truth-making [2009], p.207) | |
| A reaction: Lowe defends dependent 'modes' of things, against independent 'tropes'. Good, but he then has to say what the thing is (a modeless 'substance'?), because it can't just be a bundle of modes or tropes. |
| 1748 | Archelaus was the first person to say that the universe is boundless [Archelaus, by Diog. Laertius] |
| Full Idea: Archelaus was the first person to say that the universe is boundless. | |
| From: report of Archelaus (fragments/reports [c.450 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.Ar.3 |
| 5989 | Archelaus said life began in a primeval slime [Archelaus, by Schofield] |
| Full Idea: Archelaus wrote that life on Earth began in a primeval slime. | |
| From: report of Archelaus (fragments/reports [c.450 BCE]) by Malcolm Schofield - Archelaus | |
| A reaction: This sounds like a fairly clearcut assertion of the production of life by evolution. Darwin's contribution was to propose the mechanism for achieving it. We should honour the name of Archelaus for this idea. |
