4. Formal Logic / D. Modal Logic ML / 7. Barcan Formula

15380	Barcan:nothing comes into existence; Converse:nothing goes out; Both:domain is unchanging [Vervloesem]
	Full Idea: Intuitively, the Barcan formula says that nothing comes into existence when moving from a possible world to an alternative world. The converse says that nothing goes out of existence. Together they say the domain of quantification is fixed for all worlds.
	From: Koen Vervloesem (Barcan Formulae [2010])
	A reaction: Stated so clearly, they sound absurd. The sensible idea, I suppose, is that you can refer to all the things from any world, but that doesn't mean they are possible. Shades of Meinong. 'Square circles' are not possible.

7. Existence / A. Nature of Existence / 3. Being / e. Being and nothing

21982	I only wish I had such eyes as to see Nobody! It's as much as I can do to see real people. [Carroll,L]
	Full Idea: "I see nobody on the road," said Alice. - "I only wish I had such eyes," the King remarked. ..."To be able to see Nobody! ...Why, it's as much as I can do to see real people."
	From: Lewis Carroll (C.Dodgson) (Through the Looking Glass [1886], p.189), quoted by A.W. Moore - The Evolution of Modern Metaphysics 07.7
	A reaction: [Moore quotes this, inevitably, in a chapter on Hegel] This may be a better candidate for the birth of philosophy of language than Frege's Groundwork.

23. Ethics / E. Utilitarianism / 2. Ideal of Pleasure

20883	Modern utilitarians value knowledge, friendship, autonomy, and achievement, as well as pleasure [Hooker,B]
	Full Idea: Most utilitarians now think that pleasure, even if construed widely, is not the only thing desirable in itself. ...Goods also include important knowledge, friendship, autonomy, achievement and so on.
	From: Brad W. Hooker (Rule Utilitarianism and Euthanasia [1997], 2)
	A reaction: That pleasure is desired is empirically verifiable, which certainly motivated Bentham. A string of other desirables each needs to be justified - but how? What would be the value of a 'friendship' if neither party got pleasure from it?

23. Ethics / E. Utilitarianism / 5. Rule Utilitarianism

20884	Rule-utilitarians prevent things like torture, even on rare occasions when it seems best [Hooker,B]
	Full Idea: For rule-utilitarians acts of murder, torture and so on, can be impermissible even in rare cases where they really would produce better consequences than any alternative act.
	From: Brad W. Hooker (Rule Utilitarianism and Euthanasia [1997], 4)
	A reaction: It is basic to rule-utilitarianism that it trumps act-ulitilarianism, even when a particular act wins the utilitarian calculation. But that is hard to understand. Only long-term benefit could justify the rule - but that should win the calculation.

25. Social Practice / F. Life Issues / 2. Euthanasia

20885	Euthanasia is active or passive, and voluntary, non-voluntary or involuntary [Hooker,B]
	Full Idea: Six types of euthanasia: 1) Active voluntary (knowing my wishes), 2) Active non-voluntary (not knowing my wishes), 3) Active involuntary (against my wishes), 4) Passive voluntary, 5) Passive non-voluntary, 6) Passive involuntary.
	From: Brad W. Hooker (Rule Utilitarianism and Euthanasia [1997], 5)
	A reaction: 'Active' is intervening, and 'passive' is not intervening. A helpful framework.

20882	Euthanasia may not involve killing, so it is 'killing or not saving, out of concern for that person' [Hooker,B]
	Full Idea: Passive euthanasia is arguably not killing, and the death involved is often painful, so let us take the term 'euthanasia' to mean 'either killing or passing up opportunities to save someone, out of concern for that person'.
	From: Brad W. Hooker (Rule Utilitarianism and Euthanasia [1997], 1)
	A reaction: This sounds good, and easily settled, until you think concern for that person could have two different outcomes, depending on whether the criteria are those of the decider or of the patient. Think of religious decider and atheist patient, or vice versa.
