23367 | Even pointing a finger should only be done for a reason [Epictetus] |
Full Idea: Philosophy says it is not right even to stretch out a finger without some reason. | |
From: Epictetus (fragments/reports [c.57], 15) | |
A reaction: The key point here is that philosophy concerns action, an idea on which Epictetus is very keen. He rather despise theory. This idea perfectly sums up the concept of the wholly rational life (which no rational person would actually want to live!). |
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'. |
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. |
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. |
8353 | Freedom involves acting according to an idea [Anscombe] |
Full Idea: Freedom at least involves the power of acting according to an idea. | |
From: G.E.M. Anscombe (Causality and Determinism [1971], §2) | |
A reaction: Since 'you' presumably have to sit above the idea and pass a judgement on it, then the same principle should apply to acting on a desire, which presumably 'you' could reject because it just wasn't attractive enough. |
8352 | To believe in determinism, one must believe in a system which determines events [Anscombe] |
Full Idea: 'The ball's path is determined' must mean 'there is only one possible path for the ball (assuming no air currents)', but what ground could one have for believing this, if one does not believe in some system for which it is a consequence? | |
From: G.E.M. Anscombe (Causality and Determinism [1971], §2) | |
A reaction: This seems right, but it doesn't follow that one has to know the full details of the system. The system might just be the best explanation, or even a matter of vague faith. It might, though, be just that you can't imagine any other outcome. |
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. |
8351 | With diseases we easily trace a cause from an effect, but we cannot predict effects [Anscombe] |
Full Idea: It is much easier to trace effects back to causes with certainty than to predict effects from causes. If I have one contact with someone with a disease and I get it, we suppose I got it from him, but a doctor cannot predict a disease from one contact. | |
From: G.E.M. Anscombe (Causality and Determinism [1971], §1) | |
A reaction: An interesting, and obviously correct, observation. Her point is that we get more certainty of causes from observing a singular effect than we get certainty of effects from regularities or laws. |
4777 | The word 'cause' is an abstraction from a group of causal terms in a language (scrape, push..) [Anscombe] |
Full Idea: The word "cause" can be added to a language in which are already represented many causal concepts; a small selection: scrape, push, wet, carry, eat, burn, knock over, keep off, squash, make, hurt. | |
From: G.E.M. Anscombe (Causality and Determinism [1971], p.93) | |
A reaction: An interesting point, perhaps reinforcing the Humean idea of causation as a 'natural belief', or the Kantian view of it as a category of thought. Or maybe causation is built into language because it is a feature of reality… |
10363 | Causation is relative to how we describe the primary relata [Anscombe, by Schaffer,J] |
Full Idea: Anscombe has inspired the view that causation is an intensional relation, and takes it to be relative to the descriptions of the primary relata. | |
From: report of G.E.M. Anscombe (Causality and Determinism [1971], 1) by Jonathan Schaffer - The Metaphysics of Causation 1 | |
A reaction: It seems too linguistic to say that there is nothing more to it. It seems relevant in human examples, but if a landslide crushes a tree, what difference does the description make? 'It was just a few rocks and some miserable little tree'. No excuse! |
8350 | Since Mill causation has usually been explained by necessary and sufficient conditions [Anscombe] |
Full Idea: Since Mill it has been fairly common to explain causation one way or another in terms of 'necessary' and 'sufficient' conditions. | |
From: G.E.M. Anscombe (Causality and Determinism [1971], §1) | |
A reaction: Interesting to see what Hume implies about these criteria. Anscombe is going to propose that causal events are fairly self-evident and self-explanatory, and don't need analyses of conditions. Another approach is regularities and laws. |
