17990 | Instances of minimal truth miss out propositions inexpressible in current English [Hofweber] |
Full Idea: A standard objection to minimalist truth is the 'incompleteness objection'. Since there are propositions inexpressible in present English the concept of truth isn't captured by all the instances of the Tarski biconditional. | |
From: Thomas Hofweber (Inexpressible Properties and Propositions [2006], 5.3) | |
A reaction: Sounds like a good objection. |
17988 | Quantification can't all be substitutional; some reference is obviously to objects [Hofweber] |
Full Idea: The view that all quantification is substitutional is not very plausible in general. Some uses of quantifiers clearly seem to have the function to make a claim about a domain of objects out there, no matter how they relate to the terms in our language. | |
From: Thomas Hofweber (Inexpressible Properties and Propositions [2006], 2.1) | |
A reaction: Robust realists like myself are hardly going to say that quantification is just an internal language game. |
17989 | Since properties have properties, there can be a typed or a type-free theory of them [Hofweber] |
Full Idea: Since properties themselves can have properties there is a well-known division in the theory of properties between those who take a typed and those who take a type-free approach. | |
From: Thomas Hofweber (Inexpressible Properties and Propositions [2006], 2.2) | |
A reaction: A typed approach would imply restrictions on what it can be a property of. 'Green' is a property of surfaces, 'dark' is a property of colours. My first reaction is to opt for type-free. |
16740 | A power is not a cause, but an aptitude for a cause [Zabarella] |
Full Idea: A power is not the cause of an operation, but only the cause's aptitude for operating. | |
From: Jacob Zabarella (De rebus naturalibus [1590], De fac anim 4:col 692), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 23.5 | |
A reaction: His example is the power of running, which is actually caused by the soul (or whatever), which generates the power. A power is a very superficial thing. |
17991 | Holism says language can't be translated; the expressibility hypothesis says everything can [Hofweber] |
Full Idea: Holism says that nothing that can be said in one language can be said in another one. The expressibility hypothesis says that everything that can be said in one language can be said in every other one. | |
From: Thomas Hofweber (Inexpressible Properties and Propositions [2006], 6.4) | |
A reaction: Obviously expressibility would only refer to reasonably comprehensive languages (with basic logical connectives, for example). Personally I vote for the expressibility hypothesis, which Hofweber seems to favour. |
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 |
16571 | Prime matter is exceptionally obscure [Zabarella] |
Full Idea: Nothing in the natural world seems to be more obscure and difficult to grasp than the prime matter of things. | |
From: Jacob Zabarella (De rebus naturalibus [1590], I.1 col 133), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 2.1 | |
A reaction: This spells the beginning of the end for 'prime matter', since a late scholastic is doubting it, even before the scientists got to work. Most modern Aristotelians slide quietly past prime matter, as unhelpful. |
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. |
