11103 | We aren't stuck with our native conceptual scheme; we can gradually change it [Quine] |
Full Idea: We must not leap to the fatalistic conclusion that we are stuck with the conceptual scheme that we grew up in. We can change it bit by bit, plank by plank. | |
From: Willard Quine (Identity, Ostension, and Hypostasis [1950], 5) | |
A reaction: This is an interesting commitment to Strawson's 'revisionary' metaphysics, rather than its duller cousin 'descriptive' metaphysics. Good for Quine. Remember, though, Davidson's 'On the Very Idea of Conceptual Scheme'. |
6806 | Do not multiply entities beyond necessity [William of Ockham] |
Full Idea: Do not multiply entities beyond necessity. | |
From: William of Ockham (works [1335]) | |
A reaction: This is the classic statement of Ockham's Razor, though it is not found in his printed works. It appears to be mainly aimed at Plato's Theory of Forms. It is taken to refer to types of entities, not numbers. One seraph is as bad as a hundred. |
11092 | A river is a process, with stages; if we consider it as one thing, we are considering a process [Quine] |
Full Idea: A river is a process through time, and the river stages are its momentary parts. Identification of the river bathed in once with the river bathed in again is just what determines our subject matter to be a river process as opposed to a river stage. | |
From: Willard Quine (Identity, Ostension, and Hypostasis [1950], 1) | |
A reaction: So if we take a thing which has stages, but instead of talking about the stages we talk about a single thing that endures through them, then we are talking about a process. Sounds very good to me. |
11093 | We don't say 'red' is abstract, unlike a river, just because it has discontinuous shape [Quine] |
Full Idea: 'Red' is surely not going to be opposed to 'Cayster' [name of a river], as abstract to concrete, merely because of discontinuity in geometrical shape? | |
From: Willard Quine (Identity, Ostension, and Hypostasis [1950], 2) | |
A reaction: I've been slow to grasp the truth of this. However, Quine assumes that 'red' is concrete because 'Cayster' is, but it is perfectly arguable that 'Cayster' is an abstraction, despite all that water. |
11101 | General terms don't commit us ontologically, but singular terms with substitution do [Quine] |
Full Idea: The use of general terms does not commit us to admitting a corresponding abstract entity into our ontology, but an abstract singular term, including the law of putting equals for equals, flatly commits us to an abstract entity named by the term. | |
From: Willard Quine (Identity, Ostension, and Hypostasis [1950], 4) | |
A reaction: Does this mean that in 'for the sake of the children', I have to believe in 'sakes' if I can find a synonym which will substitute for it? |
11096 | Discourse generally departmentalizes itself to some degree [Quine] |
Full Idea: Discourse generally departmentalizes itself to some degree. | |
From: Willard Quine (Identity, Ostension, and Hypostasis [1950], 2) | |
A reaction: I pick this out because I think it is important. There is a continually shifting domain in any conversation ('what we are talking about'), and speech cannot be understand if the shifting domain or department has not been grasped. |
22132 | Species and genera are individual concepts which naturally signify many individuals [William of Ockham] |
Full Idea: In his mature nominalism, species and genera are identified with certain mental qualities called concepts or intentions of the mind. Ontologically they are individuals too, like everthing else, ...but they naturally signify many different individuals. | |
From: William of Ockham (works [1335]), quoted by Claude Panaccio - William of Ockham p.1056 | |
A reaction: 'Naturally' is the key word, because the concepts are not fictions, but natural responses to encountering individuals in the world. I am an Ockhamist. |
11099 | Understanding 'is square' is knowing when to apply it, not knowing some object [Quine] |
Full Idea: No more need be demanded of 'is square' than that our listener learn when to expect us to apply it to an object and when not; there is no need for the phrase itself to be the name in turn of a separate object of any kind. | |
From: Willard Quine (Identity, Ostension, and Hypostasis [1950], 4) |
11094 | 'Red' is a single concrete object in space-time; 'red' and 'drop' are parts of a red drop [Quine] |
Full Idea: Why not view 'red' as naming a single concrete object extended in space and time? ..To say a drop is red is to say that the one object, the drop, is a spatio-temporal part of the other, red, as a waterfall is part of a river. | |
From: Willard Quine (Identity, Ostension, and Hypostasis [1950], 2) |
11097 | Red is the largest red thing in the universe [Quine] |
Full Idea: Red is the largest red thing in the universe - the scattered total thing whose parts are all the red things. | |
From: Willard Quine (Identity, Ostension, and Hypostasis [1950], 3) |
17595 | To unite a sequence of ostensions to make one object, a prior concept of identity is needed [Quine] |
Full Idea: The concept of identity is central in specifying spatio-temporally broad objects by ostension. Without identity, n acts of ostension merely specify up to n objects. ..But when we affirm identity of object between ostensions, they refer to the same object. | |
From: Willard Quine (Identity, Ostension, and Hypostasis [1950], 1) | |
A reaction: Quine says that there is an induction involved. On the whole, Quine seems to give a better account of identity than Geach or Wiggins can offer. |
11095 | We should just identify any items which are indiscernible within a given discourse [Quine] |
Full Idea: We might propound the maxim of the 'identification of indiscernibles': Objects indistinguishable from one another within the terms of a given discourse should be construed as identical for that discourse. | |
From: Willard Quine (Identity, Ostension, and Hypostasis [1950], 2) | |
A reaction: This increasingly strikes me as the correct way to discuss such things. Identity is largely contextual, and two things can be viewed as type-identical for practical purposes (e.g. teaspoons), but distinguished if it is necessary. |
11104 | Concepts are language [Quine] |
Full Idea: Concepts are language. | |
From: Willard Quine (Identity, Ostension, and Hypostasis [1950], 5) | |
A reaction: Hm. This seems to mean that animals and pre-linguistic children have no concepts. I just don't believe that. |
11102 | Apply '-ness' or 'class of' to abstract general terms, to get second-level abstract singular terms [Quine] |
Full Idea: Applying the operator '-ness' or 'class of' to abstract general terms, we get second-level abstract singular terms. | |
From: Willard Quine (Identity, Ostension, and Hypostasis [1950], 5) | |
A reaction: This is the derivation of abstract concepts by naming classes, rather than by deriving equivalence classes. Any theory which doesn't allow multi-level abstraction is self-evidently hopeless. Quine says Frege and Russell get numbers this way. |
468 | Musical performance can reveal a range of virtues [Damon of Ath.] |
Full Idea: In singing and playing the lyre, a boy will be likely to reveal not only courage and moderation, but also justice. | |
From: Damon (fragments/reports [c.460 BCE], B4), quoted by (who?) - where? |
19381 | The past has ceased to exist, and the future does not yet exist, so time does not exist [William of Ockham] |
Full Idea: Time is composed of non-entities, because it is composed of the past which does not exist now, although it did exist, and of the future, which does not yet exist; therefore time does not exist. | |
From: William of Ockham (works [1335], 6:496), quoted by Richard T.W. Arthur - Leibniz 7 'Nominalist' | |
A reaction: I've a lot of sympathy with this! I favour Presentism, so the past is gone and the future is yet to arrive. But we have no coherent concept of a present moment of any duration to contain reality. We are just completely bogglificated by it all. |
8010 | William of Ockham is the main spokesman for God's commands being the source of morality [William of Ockham] |
Full Idea: The most notable philosopher who makes God's commandment the basis of goodness, rather than God's goodness a reason for obeying him, is William of Occam. | |
From: William of Ockham (works [1335]), quoted by Alasdair MacIntyre - A Short History of Ethics Ch.9 | |
A reaction: Either view has problems. Why choose God to obey? Obey anyone who is powerful? But how do you decide that God is good? How do we know the nature of God's commands, or the nature of God's goodness? Etc. |
16679 | Even an angel must have some location [William of Ockham, by Pasnau] |
Full Idea: Ockham dismisses the possibility of non-location out of hand, remarking that even an angel has some location. | |
From: report of William of Ockham (works [1335]) by Robert Pasnau - Metaphysical Themes 1274-1671 14.4 |
