| 13437 | A CAR and its major PART can become identical, yet seem to have different properties [Gallois] |
| Full Idea: At t1 there is a whole CAR, and a PART of it, which is everything except the right front wheel. At t2 the wheel is removed, leaving just PART, so that CAR is now PART. But PART was a proper part of CAR, and CAR had the front wheel. Different properties! | |
| From: André Gallois (Occasions of Identity [1998], 1.II) | |
| A reaction: [compressed summary] The problem is generated by appealing to Leibniz's Law. My immediate reaction is that this is the sort of trouble you get into if you include such temporal truths about things as 'properties'. |
| 16233 | Gallois hoped to clarify identity through time, but seems to make talk of it impossible [Hawley on Gallois] |
| Full Idea: A problem for Gallois is that he leaves us no way to talk about questions of genuine identity through time, and thus undercuts one motivation for his own position. | |
| From: comment on André Gallois (Occasions of Identity [1998]) by Katherine Hawley - How Things Persist 5.8 | |
| A reaction: Gallois seems to need a second theory of identity to support his Occasional Identity theory. Two things need an identity each, before we can say that the two identities coincide. (Time to read Gallois!) |
| 16025 | If things change they become different - but then no one thing undergoes the change! [Gallois] |
| Full Idea: If things really change, there can't literally be one thing before and after the change. However, if there isn't one thing before and after the change, then no thing has really undergone any change. | |
| From: André Gallois (Identity over Time [2011], Intro) | |
| A reaction: [He cites Copi for this way of expressing the problem of identity through change] There is an obvious simple ambiguity about 'change' in ordinary English. A change of property isn't a change of object. Painting a red ball blue isn't swapping it. |
| 16026 | 4D: time is space-like; a thing is its history; past and future are real; or things extend in time [Gallois] |
| Full Idea: We have four versions of Four-Dimensionalism: the relativistic view that time is space-like; a persisting thing is identical with its history (so objects are events); past and future are equally real; or (Lewis) things extend in time, with temporal parts. | |
| From: André Gallois (Identity over Time [2011], §2.5) | |
| A reaction: Broad proposed the second one. I prefer 3-D: at any given time a thing is wholly present. At another time it is wholly present despite having changed. It is ridiculous to think that small changes destroy identity. We acquire identity by dying?? |
| 14755 | Gallois is committed to identity with respect to times, and denial of simple identity [Gallois, by Sider] |
| Full Idea: Gallois's core claim is that the identity relation holds with respect to times, ...and he must claim that there is no such thing as the relation of identity simpliciter. | |
| From: report of André Gallois (Occasions of Identity [1998]) by Theodore Sider - Four Dimensionalism 5.5 | |
| A reaction: Gallois is essentially responding to the statue and clay problem, but it seems a bit drastic to entirely change our concept of two things being identical, such as Hesperus and Phosphorus. 'Identity' seems to have several meanings; let's sort them out. |
| 16231 | Occasional Identity: two objects can be identical at one time, and different at others [Gallois, by Hawley] |
| Full Idea: Gallois' Occasional Identity Thesis is that objects can be identical at one time without being identical at all times. | |
| From: report of André Gallois (Occasions of Identity [1998]) by Katherine Hawley - How Things Persist 5.4 | |
| A reaction: The analogy is presumably with two crossing roads being identical at one place but not at others. It is a major misunderstanding to infer from Special Relativity that time is just like space. |
| 16027 | If two things are equal, each side involves a necessity, so the equality is necessary [Gallois] |
| Full Idea: The necessity of identity: a=b; □(a=a); so something necessarily = a; so something necessarily must equal b; so □(a=b). [A summary of the argument of Marcus and Kripke] | |
| From: André Gallois (Identity over Time [2011], §3) | |
| A reaction: [Lowe 1982 offered a response] The conclusion seems reasonable. If two things are mistakenly thought to be different, but turn out to be one thing, that one thing could not possibly be two things. In no world is one thing two things! |
| 20653 | Six reduction levels: groups, lives, cells, molecules, atoms, particles [Putnam/Oppenheim, by Watson] |
| Full Idea: There are six 'reductive levels' in science: social groups, (multicellular) living things, cells, molecules, atoms, and elementary particles. | |
| From: report of H.Putnam/P.Oppenheim (Unity of Science as a Working Hypothesis [1958]) by Peter Watson - Convergence 10 'Intro' | |
| A reaction: I have the impression that fields are seen as more fundamental that elementary particles. What is the status of the 'laws' that are supposed to govern these things? What is the status of space and time within this picture? |
| 20877 | Errors in moral practice might be inconsistent or inappropriate principles, or inappropriate application [LaFollette] |
| Full Idea: I might make parallel 'mistakes' in ethical deliberation. For instance I might 1) use inconsistent ethical principles, 2) have inappropriate moral standards, and 3) apply moral standards inappropriately. | |
| From: Hugh LaFollette (Introductions in 'Ethics in Practice' [2002], p.005) | |
| A reaction: I would want to get the word 'values' in there somewhere. Dogmatic application of moral rules might indicate a failure of values. |
| 20878 | We can discuss the criteria of a judgment, or the weight given to them, or their application [LaFollette] |
| Full Idea: In discussing a movie you can challenge my criteria, the weight I give to those criteria, or my application of the criteria (the claim that the movie satisfies the criteria). | |
| From: Hugh LaFollette (Introductions in 'Ethics in Practice' [2002], p.008) | |
| A reaction: I can't think of anything missing here, so it is a helpful start. |
| 20881 | The act/omission distinction is important for duties, but less so for consequences [LaFollette] |
| Full Idea: Consequentialists, unlike deontologists, are unlikely to think that the act/omission distinction is fundamentally important. | |
| From: Hugh LaFollette (Introductions in 'Ethics in Practice' [2002], p.021) | |
| A reaction: Not sure where virtue theory fits in here. Virtues tend to be applied more locally, where duty tends to be global. All moral theories must acknowledge that failure to act may be either a good or a bad thing, depending on circumstances |
| 20886 | Are we only obligated by agreement, or should we always help the weak? [LaFollette] |
| Full Idea: A fundamental question in morality is whether we are obligated to help only those we specifically agreed to help, or are we obligated to help others in need, because they are vulnerable? | |
| From: Hugh LaFollette (Introductions in 'Ethics in Practice' [2002], p.061) | |
| A reaction: [He is considering J.J. Thomson's defence of abortion] The first option sounds extraordinary. If I don't make any agreements at all, then I cease to be a moral being? Not help strangers when they fall over? |
| 20879 | Too many options may open us to unwanted pressures, like being paid very little [LaFollette] |
| Full Idea: Having options is not an unadulterated good. Options may make us vulnerable to unwanted pressure from others. For example, having the option to work for less than the minimum wage increases the chances of employers offering less. | |
| From: Hugh LaFollette (Introductions in 'Ethics in Practice' [2002], p.019) | |
| A reaction: [J.D. Velleman is cited for this] A nice point, beginning to articulate my growing feeling that although freedom is generally a virtue, it is the most overrated virtue. |
| 20880 | Should people be forced to make choices? [LaFollette] |
| Full Idea: Should we give people choices they might not want to have? | |
| From: Hugh LaFollette (Introductions in 'Ethics in Practice' [2002], p.020) | |
| A reaction: In personal life we encounter people who force us to make an unwanted choice (choose the wine, when you know nothing about wine). Politically, there is the sneaky move of giving unwanted choices, to disguise absence of desired choices. |
