10 ideas
22708 | Good reasons must give way to better [Shakespeare] |
Full Idea: Good reasons must of force give way to better. | |
From: William Shakespeare (Julius Caesar [1599], 4.3.205) | |
A reaction: [Brutus to Cassius] This remark is an axiom of rationality. But, of course, reasons can come in groups, and three modest reasons may compete with one very good reason. |
4483 | If abstract terms are sets of tropes, 'being a unicorn' and 'being a griffin' turn out identical [Loux] |
Full Idea: If trope theorists say abstract singular terms name sets of tropes, what is the referent of 'is a unicorn'? The only candidate is the null set (with no members), but there is just one null set, so 'being a unicorn' and 'being a griffin' will be identical. | |
From: Michael J. Loux (Metaphysics: contemporary introduction [1998], p.86) | |
A reaction: Not crucial, I would think, given that a unicorn is just a horse with a horn. Hume explains how we do that, combining ideas which arose from actual tropes. |
4481 | Austere nominalists insist that the realist's universals lack the requisite independent identifiability [Loux] |
Full Idea: Austere nominalists insist that the realist's universals lack the requisite independent identifiability. | |
From: Michael J. Loux (Metaphysics: contemporary introduction [1998], p.60) | |
A reaction: Plato's view seems to be that we don't identify universals independently. We ascend The Line, or think about the shadows in The Cave, and infer the universals from an array of particulars (by dialectic). |
4477 | Universals come in hierarchies of generality [Loux] |
Full Idea: Universals come in hierarchies of generality. | |
From: Michael J. Loux (Metaphysics: contemporary introduction [1998], p.24) | |
A reaction: If it is possible to state facts about universals, this obviously encourages a rather Platonic approach to them, as existent things with properties. But maybe the hierarchies are conventional, not natural. |
4482 | Austere nominalism has to take a host of things (like being red, or human) as primitive [Loux] |
Full Idea: In return for a one-category ontology (with particulars but no universals), the austere nominalist is forced to take a whole host of things (like being red, or triangular, or human) as unanalysable or primitive. | |
From: Michael J. Loux (Metaphysics: contemporary introduction [1998], p.68) | |
A reaction: I see that 'red' might have to be primitive, but being human can just be a collection of particulars. It is no ontologically worse to call them 'primitive' than to say they exist. |
4478 | Nominalism needs to account for abstract singular terms like 'circularity'. [Loux] |
Full Idea: Nominalists have been very concerned to provide an account of the role of abstract singular terms (such as 'circularity'). | |
From: Michael J. Loux (Metaphysics: contemporary introduction [1998], p.34) | |
A reaction: Whether this is a big problem depends on our view of abstraction. If it only consists of selecting one property of an object and reifying it, then we can give a nominalist account of properties, and the problem is solved. |
4480 | Times and places are identified by objects, so cannot be used in a theory of object-identity [Loux] |
Full Idea: Any account of the identity of material objects which turns on the identity of places and times must face the objection that the identity of places and times depends, in turn, on the identities of the objects located at them. | |
From: Michael J. Loux (Metaphysics: contemporary introduction [1998], p.56) | |
A reaction: This may be a benign circle, in which we concede that there are two basic interdependent concepts of objects and space-time. If you want to define identity - in terms of what? |
15990 | Every individual thing which exists has an essence, which is its internal constitution [Locke] |
Full Idea: I take essences to be in everything that internal constitution or frame for the modification of substance, which God in his wisdom gives to every particular creature, when he gives it a being; and such essences I grant there are in all things that exist. | |
From: John Locke (Letters to Edward Stillingfleet [1695], Letter 1), quoted by Simon Blackburn - Quasi-Realism no Fictionalism | |
A reaction: This is the clearest statement I have found of Locke's commitment to essences, for all his doubts about whether we can know such things. Alexander says (ch.13) Locke was reacting against scholastic essence, as pertaining to species. |
15994 | If it is knowledge, it is certain; if it isn't certain, it isn't knowledge [Locke] |
Full Idea: What reaches to knowledge, I think may be called certainty; and what comes short of certainty, I think cannot be knowledge. | |
From: John Locke (Letters to Edward Stillingfleet [1695], Letter 2), quoted by Simon Blackburn - Quasi-Realism no Fictionalism | |
A reaction: I much prefer that fallibilist approach offered by the pragmatists. Knowledge is well-supported belief which seems (and is agreed) to be true, but there is a small shadow of doubt hanging over all of it. |
20304 | The cause of my action is in my will [Shakespeare] |
Full Idea: The cause is in my will. I will not come./That is enough to satisfy the senate./But for your private satisfaction,/Because I love you, I will let you know. | |
From: William Shakespeare (Julius Caesar [1599], II.ii) | |
A reaction: This asserts the purest form of volitionism, but then qualifies it, because Caesar's will has been influenced by his wife's dreams. |
