| 22701 | Jokes can sometimes be funny because they are offensive [Jacobson,D] |
| Full Idea: Sometimes it is exactly what is offensive about a joke that makes it funny. | |
| From: Daniel Jacobson (Ethical Criticism and the Vice of Moderation [2006], 'emotional') | |
| A reaction: Jacobson offers this in support of his immoralist view, that immoral literature can be aesthetically successful. It is uncomfortable to find yourself laughing at a joke of which you disapprove. |
| 11193 | Understanding begins with the notion of being and essence [Avicenna] |
| Full Idea: Understanding begins with the notion of being and essence. | |
| From: Avicenna (Abu Ibn Sina) (Commentary on the Metaphysics [1022], 1/6), quoted by Thomas Aquinas - De Ente et Essentia (Being and Essence) p.91 | |
| A reaction: I think I might put it that wisdom is only really possible for people who aim to grasp being and essence in some way. I see no prospect of understanding 'being', and even essences may be forever just beyond our grasp. |
| 8952 | We reach 'reflective equilibrium' when intuitions and theory completely align [Fisher] |
| Full Idea: A state of 'reflective equilibrium' is when our theory and our intuitions become completely aligned | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 12.IV) | |
| A reaction: [Rawls made this concept famous] This is a helpful concept in trying to spell out the ideal which is the dream of believers in 'pure reason' - that there is a goal in which everything comes right. The problem is when people have different intuitions! |
| 8943 | Three-valued logic says excluded middle and non-contradition are not tautologies [Fisher] |
| Full Idea: In three-valued logic (L3), neither the law of excluded middle (p or not-p), nor the law of non-contradiction (not(p and not-p)) will be tautologies. If p has the value 'indeterminate' then so will not-p. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 07.I) | |
| A reaction: I quite accept that the world is full of indeterminate propositions, and that excluded middle and non-contradiction can sometimes be uncertain, but I am reluctant to accept that what is being offered here should be called 'logic'. |
| 8945 | Fuzzy logic has many truth values, ranging in fractions from 0 to 1 [Fisher] |
| Full Idea: In fuzzy logic objects have properties to a greater or lesser degree, and truth values are given as fractions or decimals, ranging from 0 to 1. Not-p is defined as 1-p, and other formula are defined in terms of maxima and minima for sets. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 07.II) | |
| A reaction: The question seems to be whether this is actually logic, or a recasting of probability theory. Susan Haack attacks it. If logic is the study of how truth is preserved as we move between propositions, then 0 and 1 need a special status. |
| 8951 | Classical logic is: excluded middle, non-contradiction, contradictions imply all, disjunctive syllogism [Fisher] |
| Full Idea: For simplicity, we can say that 'classical logic' amounts to the truth of four sentences: 1) either p or not-p; 2) it is not the case that both p and not-p; 3) from p and not-p, infer q; 4) from p or q and not-p, infer q. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 12.I) | |
| A reaction: [She says there are many ways of specifying classical logic] Intuition suggests that 2 and 4 are rather hard to dispute, while 1 is ignoring some grey areas, and 3 is totally ridiculous. There is, of course, plenty of support for 3! |
| 8950 | Logic formalizes how we should reason, but it shouldn't determine whether we are realists [Fisher] |
| Full Idea: Even if one is inclined to be a realist about everything, it is hard to see why our logic should be the determiner. Logic is supposed to formalize how we ought to reason, but whether or not we should be realists is a matter of philosophy, not logic. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 09.I) | |
| A reaction: Nice to hear a logician saying this. I do not see why talk in terms of an object is a commitment to its existence. We can discuss the philosopher's stone, or Arthur's sword, or the Loch Ness monster, or gravitinos, with degrees of commitment. |
| 8946 | We could make our intuitions about heaps precise with a million-valued logic [Fisher] |
| Full Idea: We could construct a 1,000,000-valued logic that would allow our intuitions concerning a heap to vary exactly with the amount of sand in the heap. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008]) | |
| A reaction: Presumably only an infinite number of grains of sand would then produce a true heap, and even one grain would count as a bit of a heap, which must both be wrong, so I can't see this helping much. |
| 11209 | The simple's whatness is its very self [Avicenna] |
| Full Idea: The simple's whatness is its very self. | |
| From: Avicenna (Abu Ibn Sina) (Commentary on the Metaphysics [1022], 5.5), quoted by Thomas Aquinas - De Ente et Essentia (Being and Essence) p.103 | |
| A reaction: Aquinas endorses this Aristotelian view in Idea 11208. |
| 8944 | Vagueness can involve components (like baldness), or not (like boredom) [Fisher] |
| Full Idea: Vague terms come in at least two different kinds: those whose constituent parts come in discrete packets (bald, rich, red) and those that don't (beauty, boredom, niceness). | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 07.II) | |
| A reaction: The first group seem to be features of the external world, and the second all occur in the mind. Baldness may be vague, but presumably hairs are (on the whole) not. Nature doesn't care whether someone is actually 'bald' or not. |
| 11204 | The ultimate material of things has the unity of total formlessness [Avicenna] |
| Full Idea: The ultimate material of things has the unity of total formlessness. | |
| From: Avicenna (Abu Ibn Sina) (Commentary on the Metaphysics [1022], 11/12.14), quoted by Thomas Aquinas - De Ente et Essentia (Being and Essence) | |
| A reaction: This remark is not invalidated by developments in modern particle physics. |
| 15036 | An essence can either be universal (in the mind) or singular (in concrete particulars) [Avicenna, by Panaccio] |
| Full Idea: Avicenna's 'indifference of essence' says the essence of certain things can become universal or singular, according to whether it is entertained by the mind (as a universal) or concretely exemplified as a singular thing. One essence can exist in two ways. | |
| From: report of Avicenna (Abu Ibn Sina) (Commentary on the Metaphysics [1022]) by Claude Panaccio - Medieval Problem of Universals 'Sources' | |
| A reaction: This would appear to be a form of nominalism, since in the concrete external world we only have particulars, and it is our mode of thinking (by abstraction?) that generates the universal aspect. I think this is probably right. |
| 8941 | We can't explain 'possibility' in terms of 'possible' worlds [Fisher] |
| Full Idea: Explaining 'it is possible that p' by saying p is true in at least one possible world doesn't get me very far. If I don't understand what possibility is, then appealing to possible worlds is not going to do me much good. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 06.III) | |
| A reaction: This seems so blatant that I assume friends of possible worlds will have addressed the problem. Note that you will also need to understand 'possible' to define necessity as 'true in all possible worlds'. Necessarily-p is not-possibly-not-p. |
| 8947 | If all truths are implied by a falsehood, then not-p might imply both q and not-q [Fisher] |
| Full Idea: If all truths are implied by a falsehood, then 'if there are no trees in the park then there is no shade' and 'if there are no trees in the park there is plenty of shade' both come out as true. Intuitively, though, the second one is false. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 08.I) | |
| A reaction: The rule that a falsehood implies all truths must be the weakest idea in classical logic, if it actually implies a contradiction. This means we must take an interest in relevance logics. |
| 8949 | In relevance logic, conditionals help information to flow from antecedent to consequent [Fisher] |
| Full Idea: A good account of relevance logic suggests that a conditional will be true when the flow of information is such that a conditional is the device that helps information to flow from the antecedent to the consequent. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 08.III) | |
| A reaction: Hm. 'If you are going out, you'll need an umbrella'. This passes on information about 'out', but also brings in new information. 'If you are going out, I'm leaving you'. What flows is an interpretation of the antecedent. Tricky. |
| 22703 | We don't often respond to events in art as if they were real events [Jacobson,D] |
| Full Idea: We routinely do not respond to art as if we were as if we were real-life spectators of its events. | |
| From: Daniel Jacobson (Ethical Criticism and the Vice of Moderation [2006], 'rejection') | |
| A reaction: This strikes me as one of the basic facts about aesthetics, and especially of narrative art. People sometimes encounter terrible events on the street, only to find someone is making a film. |
| 22702 | Audiences can be too moral [Jacobson,D] |
| Full Idea: An audience can be overly moralistic. | |
| From: Daniel Jacobson (Ethical Criticism and the Vice of Moderation [2006], 'emotional') | |
| A reaction: People can be too moral in real life as well. Goody Two Shoes. |
| 22696 | 'Autonomism' says the morality is irrelevant to the aesthetics [Jacobson,D] |
| Full Idea: 'Autonomism' is the theory that the intrinsic moral merits and defects of an artwork are irrelevant to its aesthetic value. | |
| From: Daniel Jacobson (Ethical Criticism and the Vice of Moderation [2006], Intro) | |
| A reaction: This contrasts with 'moralism', which says the ethics is part of the aesthetics. Autonomism seems to be the modern academic label for art for art's sake. In nineteenth century novels the ethics are central; in modernist novels they seem to be irrelevant. |
| 22697 | Moral defects of art can be among its aesthetic virtues [Jacobson,D] |
| Full Idea: To put my claim most provocatively: the moral defects in a work of art can be among its aesthetic virtues. This claim has been called 'immoralism'. | |
| From: Daniel Jacobson (Ethical Criticism and the Vice of Moderation [2006], Intro) | |
| A reaction: To describe sympathetic descriptions of vile moral behaviour as 'defects' may be a misunderstanding. If a work sets out to promote wickedness, then its wickedness isn't a defect in the work. It could be a masterpiece of corruption. |
| 22700 | Immoral art encourages immoral emotions [Jacobson,D] |
| Full Idea: Humean moralism includes the view that immoral art prescribes unethical emotional responses. | |
| From: Daniel Jacobson (Ethical Criticism and the Vice of Moderation [2006], 'emotional') | |
| A reaction: [He cites Hume's 'On the Standard of Taste'] 'Prescribes' is tricky. Is a vivid description of wicked events, given without comment, a prescription? What if the commentary condemns, but the description entices? Trust the work itself, said Lawrence. |
| 22699 | Moderate moralism says moral qualities can sometimes also be aesthetic qualities [Jacobson,D] |
| Full Idea: Noël Carroll's moderate moralism maintains that some moral defects in artworks are aesthetic defects, and some moral virtues are aesthetic merits. | |
| From: Daniel Jacobson (Ethical Criticism and the Vice of Moderation [2006], 'How moderate') | |
| A reaction: I'm beginning to think that moralist critics are confusing morality and wisdom. We don't admire novels for hammering on about goodness. We admire their insight into characters and actions, of which the most interesting aspects happen to be moral. |
| 22698 | We can judge art ethically, or rate its ethical influence, or assess its quality via its ethics [Jacobson,D] |
| Full Idea: Ethical criticism includes 1) ethical judgements of art works, 2) assessment of an art work's role in moral education, or 3) bringing moral praise or censure to bear on the aesthetic evaluation. | |
| From: Daniel Jacobson (Ethical Criticism and the Vice of Moderation [2006], 'What is') | |
| A reaction: [a compressed summary of Jacobson. He cites Levinson 1998 and Carroll 2000 as examples of ethical criticism] |
