2. Reason / D. Definition / 13. Against Definition
Most people can't even define a chair [Peacocke]
     Full Idea: Ordinary speakers are notoriously unsuccessful if asked to offer an explicit definition of the concept 'chair'.
     From: Christopher Peacocke (A Study of Concepts [1992], 6.1)
9. Objects / C. Structure of Objects / 4. Quantity of an Object
Quantity is the capacity to be divided [Digby]
     Full Idea: Quantity …is divisibility, or a capacity to be divided into parts.
     From: Kenelm Digby (Two treatises [1644], I.2.8), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 04.1
     A reaction: 'Quantity' is scholastic philosophy is a concept we no longer possess. Without quantity, a thing might potentially exist at a spaceless point. Quantity is what spreads things out. See Pasnau Ch. 4.
12. Knowledge Sources / B. Perception / 1. Perception
Perceptual concepts causally influence the content of our experiences [Peacocke]
     Full Idea: Once a thinker has acquired a perceptually individuated concept, his possession of that concept can causally influence what contents his experiences possess.
     From: Christopher Peacocke (A Study of Concepts [1992], 3.3)
     A reaction: Like having 35 different words for 'snow', I suppose. I'm never convinced by such claims. Having the concepts may well influence what you look at or listen to, but I don't see the deliverances of the senses being changed by the concepts.
12. Knowledge Sources / B. Perception / 6. Inference in Perception
Perception has proto-propositions, between immediate experience and concepts [Peacocke]
     Full Idea: Perceptual experience has a second layer of nonconceptual representational content, distinct from immediate 'scenarios' and from conceptual contents. These additional contents I call 'protopropositions', containing an individual and a property/relation.
     From: Christopher Peacocke (A Study of Concepts [1992], 3.3)
     A reaction: When philosophers start writing this sort of thing, I want to turn to neuroscience and psychology. I suppose the philosopher's justification for this sort of speculation is epistemological, but I see no good coming of it.
15. Nature of Minds / B. Features of Minds / 1. Consciousness / f. Higher-order thought
Consciousness of a belief isn't a belief that one has it [Peacocke]
     Full Idea: I dispute the view that consciousness of a belief consists in some kind of belief that one has the belief.
     From: Christopher Peacocke (A Study of Concepts [1992], 6.2)
     A reaction: Thus if one is trying to grasp the notion of higher-order thought, it doesn't have to be just more of same but one level up. Any sensible view of the brain would suggest that one sort of activity would lead into an entirely different sort.
16. Persons / A. Concept of a Person / 1. Existence of Persons
Persons are conscious, they relate, they think, they feel, and they are self-aware [Glover]
     Full Idea: We think of 'persons' as conscious, able to form relationships, capable of thought, having emotional responses, and having some sense of their own identity.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §9.4)
     A reaction: A notable addition to Locke's definition is the capacity for relationships. So are autistic children not persons? Is feeling necessary? Mr Spock is then in trouble.
18. Thought / A. Modes of Thought / 6. Judgement / a. Nature of Judgement
Concepts are distinguished by roles in judgement, and are thus tied to rationality [Peacocke]
     Full Idea: 'Concept' is a notion tied, in the classical Fregean manner, to cognitive significance. Concepts are distinct if we can judge rationally of one, without the other. Concepts are constitutively and definitionally tied to rationality in this way.
     From: Christopher Peacocke (Truly Understood [2008], 2.2)
     A reaction: It seems to a bit optimistic to say, more or less, that thinking is impossible if it isn't rational. Rational beings have been selected for. As Quine nicely observed, duffers at induction have all been weeded out - but they may have existed, briefly.
18. Thought / D. Concepts / 1. Concepts / b. Concepts in philosophy
Philosophy should merely give necessary and sufficient conditions for concept possession [Peacocke, by Machery]
     Full Idea: Peacocke's 'Simple Account' says philosophers should determine the necessary and sufficient conditions for possessing a concept, and psychologists should explain how the human mind meets these conditions.
     From: report of Christopher Peacocke (A Study of Concepts [1992]) by Edouard Machery - Doing Without Concepts 2
     A reaction: One can't restrict philosophy so easily. Psychologists could do that job themselves, and dump philosophy. Philosophy is interested in the role of concepts in meaning, experience and judgement. If psychologists can contribute to philosophy, fine.
Peacocke's account of possession of a concept depends on one view of counterfactuals [Peacocke, by Machery]
     Full Idea: Peacocke's method for discovering the possession conditions of concepts is committed to a specific account of counterfactual judgements - the Simulation Model (judgements we'd make if the antecedent were actual).
     From: report of Christopher Peacocke (A Study of Concepts [1992]) by Edouard Machery - Doing Without Concepts 2.3.4
     A reaction: Machery concludes that the Simulation Model is incorrect. This appears to be Edgington's theory of conditionals, though Machery doesn't mention her.
Peacocke's account separates psychology from philosophy, and is very sketchy [Machery on Peacocke]
     Full Idea: Peacocke's Simple Account fails to connect the psychology and philosophy of concepts, it subordinates psychology to specific field of philosophy, it is committed to analytic/synthetic, and (most important) its method is very sketchy.
     From: comment on Christopher Peacocke (A Study of Concepts [1992]) by Edouard Machery - Doing Without Concepts 2.3.5
     A reaction: Machery says Peacocke proposes a research programme, and he is not surprised that no one has every followed. Machery is a well-known champion of 'experimental philosophy', makes philosophy respond to the psychology.
18. Thought / D. Concepts / 2. Origin of Concepts / a. Origin of concepts
The concept 'red' is tied to what actually individuates red things [Peacocke]
     Full Idea: The possession conditions for the concept 'red' of the colour red are tied to those very conditions which individuate the colour red.
     From: Christopher Peacocke (Explaining the A Priori [2000], p.267), quoted by Carrie Jenkins - Grounding Concepts 2.5
     A reaction: Jenkins reports that he therefore argues that we can learn something about the word 'red' from thinking about the concept 'red', which is his new theory of the a priori. I find 'possession conditions' and 'individuation' to be very woolly concepts.
18. Thought / D. Concepts / 3. Ontology of Concepts / a. Concepts as representations
If concepts just are mental representations, what of concepts we may never acquire? [Peacocke]
     Full Idea: We might say that the concept just is the mental representation, ...but there are concepts that human beings may never acquire. ...But if concepts are individuated by their possession conditions this will not be a problem.
     From: Christopher Peacocke (Rationale and Maxims in Study of Concepts [2005], p.169), quoted by E Margolis/S Laurence - Concepts 1.3
     A reaction: I'm not sure that I understand the notion of a concept we (or any other creature) may never acquire. They no more seem to exist than buildings that were never even designed.
18. Thought / D. Concepts / 3. Ontology of Concepts / b. Concepts as abilities
Possessing a concept is being able to make judgements which use it [Peacocke]
     Full Idea: Possession of any concept requires the capacity to make judgements whose content contain it.
     From: Christopher Peacocke (A Study of Concepts [1992], 2.1)
     A reaction: Idea 12575 suggested that concept possession was an ability just to think about the concept. Why add that one must actually be able to make a judgement? Presumably to get truth in there somewhere. I may only speculate and fantasise, rather than judge.
A concept is just what it is to possess that concept [Peacocke]
     Full Idea: There can be no more to a concept than is determined by a correct account of what it is to possess that concept.
     From: Christopher Peacocke (A Study of Concepts [1992], 3.2)
     A reaction: He calls this the Principle of Dependence. An odd idea, if you compare 'there is no more to a book than its possession conditions'. If the principle is right, I struggle with the proposal that a philosopher might demonstrate such a principle.
Employing a concept isn't decided by introspection, but by making judgements using it [Peacocke]
     Full Idea: On the account I have been developing, what makes it the case that someone is employing one concept rather than another is not constituted by his impression of whether he is, but by complex facts about explanations of his judgements.
     From: Christopher Peacocke (A Study of Concepts [1992], 7.2)
     A reaction: I presume this brings truth into the picture, and hence establishes a link between the concept and the external world, rather than merely with other concepts. There seems to be a shadowy behaviourism lurking in the background.
18. Thought / D. Concepts / 3. Ontology of Concepts / c. Fregean concepts
A sense is individuated by the conditions for reference [Peacocke]
     Full Idea: My basic Fregean idea is that a sense is individuated by the fundamental condition for something to be its reference.
     From: Christopher Peacocke (Truly Understood [2008], Intro)
     A reaction: For something to actually be its reference (as opposed to imagined reference), truth must be involved. This needs the post-1891 Frege view of such things, and not just the view of concepts as functions which he started with.
Fregean concepts have their essence fixed by reference-conditions [Peacocke]
     Full Idea: The Fregean view is that the essence of a concept is given by the fundamental condition for something to be its reference.
     From: Christopher Peacocke (Truly Understood [2008], 2.1)
     A reaction: Peacocke is a supporter of the Fregean view. How does this work for concepts of odd creatures in a fantasy novel? Or for mistaken or confused concepts? For Burge's 'arthritis in my thigh'? I don't reject the Fregean view.
18. Thought / D. Concepts / 4. Structure of Concepts / a. Conceptual structure
Concepts have distinctive reasons and norms [Peacocke]
     Full Idea: For each concept, there will be some reasons or norms distinctive of that concept.
     From: Christopher Peacocke (Truly Understood [2008], 2.3)
     A reaction: This is Peacocke's bold Fregean thesis (and it sounds rather Kantian to me). I dislike the word 'norms' (long story), but reasons are interesting. The trouble is the distinction between being a reason for something (its cause) and being a reason for me.
18. Thought / D. Concepts / 4. Structure of Concepts / b. Analysis of concepts
An analysis of concepts must link them to something unconceptualized [Peacocke]
     Full Idea: At some point a good account of conceptual mastery must tie the mastery to abilities and relations that do not require conceptualization by the thinker.
     From: Christopher Peacocke (A Study of Concepts [1992], 5.3)
     A reaction: This obviously implies a physicalist commitment. Peacocke seeks, as so many do these days in philosophy of maths, to combine this commitment with some sort of Fregean "platonism without tears" (p.101). I don't buy it.
Any explanation of a concept must involve reference and truth [Peacocke]
     Full Idea: For some particular concept, we can argue that some of its distinctive features are adequately explained only by a possession-condition that involves reference and truth essentially.
     From: Christopher Peacocke (Truly Understood [2008], Intro)
     A reaction: He reached this view via the earlier assertion that it is the role in judgement which key to understanding concepts. I like any view of such things which says that truth plays a role.
18. Thought / D. Concepts / 4. Structure of Concepts / f. Theory theory of concepts
Concepts are constituted by their role in a group of propositions to which we are committed [Peacocke, by Greco]
     Full Idea: Peacocke argues that it may be a condition of possessing a certain concept that one be fundamentally committed to certain propositions which contain it. A concept is constituted by playing a specific role in the cognitive economy of its possessor.
     From: report of Christopher Peacocke (A Study of Concepts [1992]) by John Greco - Justification is not Internal §9
     A reaction: Peacocke is talking about thought and propositions rather than language. Good for him. I always have problems with this sort of view: how can something play a role if it doesn't already have intrinsic properties to make the role possible?
19. Language / B. Reference / 1. Reference theories
A concept's reference is what makes true the beliefs of its possession conditions [Peacocke, by Horwich]
     Full Idea: Peacocke has a distinctive view of reference: The reference of a concept is that which will make true the primitively compelling beliefs that provide its possession conditions.
     From: report of Christopher Peacocke (A Study of Concepts [1992]) by Paul Horwich - Stipulation, Meaning and Apriority §9
     A reaction: The first thought is that there might occasionally be more than one referent which would do the job. It seems to be a very internal view of reference, where I take reference to be much more contextual and social.
19. Language / C. Assigning Meanings / 4. Compositionality
Encountering novel sentences shows conclusively that meaning must be compositional [Peacocke]
     Full Idea: The phenomenon of understanding sentences one has never encountered before is decisive against theories of meaning which do not proceed compositionally.
     From: Christopher Peacocke (Truly Understood [2008], 4.3)
     A reaction: I agree entirely. It seems obvious, as soon as you begin to slowly construct a long and unusual sentence, and follow the mental processes of the listener.
20. Action / C. Motives for Action / 5. Action Dilemmas / a. Dilemmas
A problem arises in any moral system that allows more than one absolute right [Glover]
     Full Idea: A problem arises in any moral system that allows more than one absolute right.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §5.6)
     A reaction: Presumably the right to rest on Sunday doesn't conflict with the right to disabled parking on weekdays. He has, though, a point…
20. Action / C. Motives for Action / 5. Action Dilemmas / b. Double Effect
Double Effect: no bad acts with good consequences, but possibly good acts despite bad consequences [Glover]
     Full Idea: The doctrine of double effect says (crudely) it is wrong to intentionally do a bad act for its good consequences, but it may be permissible to do a good act despite its foreseeable bad consequences. (..Shoot an innocent man to avoid his agonising death?)
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §6)
     A reaction: Glover rejects this principle, because he is a utilitarian. The principle implies a doubtful sharp distinction between an act and its consequences. If you foresee bad consequences, why do you go ahead and do it? I doubt if there are purely good acts.
20. Action / C. Motives for Action / 5. Action Dilemmas / c. Omissions
Acts and Omissions: bad consequences are morally better if they result from an omission rather than an act [Glover]
     Full Idea: The acts and omissions doctrine says failure to perform an act, when there are foreseen bad consequences of the failure, is usually better than performing a different act which has the same foreseen consequences.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §7)
     A reaction: Is it better if my neglect causes famine in Ethiopia than if my theft causes it? Glover (a consequentialist) rejects this. Depends. What are reasonable expectations? Acts set an example. Minor bad acts are clearly better than callous negligence.
It doesn't seem worse to switch off a life-support machine than to forget to switch it on [Glover]
     Full Idea: If someone is being kept alive on a respirator and I switch it off, this makes death no more certain than if, when attaching the patient to the machine, I fail to switch it on.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §7.4)
     A reaction: In practice, though, neglect is more excusable than a bad act, and (crucially) bad actions always indicate a bad character, whereas neglect may indicate a good person who is very busy. Neglect can, of course, be very wicked.
Harmful omissions are unavoidable, while most harmful acts can be avoided [Glover]
     Full Idea: Harmful omissions are unavoidable, while most harmful acts can be avoided.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §7.8)
     A reaction: This does suggest why we get angry with bad actions, but are very tolerant of omissions. It is also easier to motivate positive actions than to worry about things undone. Omissions can be disgraceful.
22. Metaethics / B. Value / 2. Values / c. Life
What matters is not intrinsic value of life or rights, but worthwhile and desired life, and avoidance of pain [Glover]
     Full Idea: It is not wrong to kill because of the intrinsic value of life or consciousness, or because people have a right to life, but because we shouldn't reduce worthwhile life, or thwart someone's desire to live, or inflict fear or pain.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §8.1)
     A reaction: This is a utilitarian view. It is not clear how we decide 'worthwhile' without a notion of intrinsic value. It is unclear why this desire is respected if many other desires are not.
22. Metaethics / B. Value / 2. Values / e. Death
'Death' is best seen as irreversible loss of consciousness, since this is why we care about brain function [Glover]
     Full Idea: It seems best to define 'death' in terms of irreversible loss of consciousness itself, since it is from this alone that our interest in the electrical activity of the brain derives.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §3.3)
     A reaction: I see the point, but this implies no further interest in a loved one who will not regain consciousness. What about subconscious acitivity, or dreamlike states without proper awareness of the external world?
22. Metaethics / C. The Good / 1. Goodness / g. Consequentialism
You can't separate acts from the people performing them [Glover]
     Full Idea: A mistake of consequentialists is to treat actions as though they can somehow be isolated from the people performing them.
     From: Jonathan Glover (Introductions to Utilitarianism and its Critics [1990], Pt Five)
     A reaction: I agree. The weather produces consequences. Morality is about people. Crocodiles, for example, are exempt.
22. Metaethics / C. The Good / 1. Goodness / h. Good as benefit
Aggression in defence may be beneficial but morally corrupting [Glover]
     Full Idea: Forming the intention to use nuclear retaliation if attacked may both be the best way to avoid the catastrophe of nuclear war and at the same time be morally corrupting.
     From: Jonathan Glover (Introductions to Utilitarianism and its Critics [1990], Pt Five)
     A reaction: A famous moment in 2017 when Jeremy Corbyn refused to say he would be willing to use the weapons, if elected. It would be hard to sustain a determination to do it, and then reject it at the crucial moment.
22. Metaethics / C. The Good / 2. Happiness / d. Routes to happiness
The quality of a life is not altogether independent of its length [Glover]
     Full Idea: The quality of a life is not altogether independent of its length.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §3.9)
     A reaction: A nice illustration of the fact that neat distinctions nearly always begin to blur when you think about reality. But a blurred distinction is still a distinction…
23. Ethics / D. Deontological Ethics / 1. Deontology
Duty prohibits some acts, whatever their consequences [Glover]
     Full Idea: The deontological view is that some acts are absolutely prohibited, regardless of consequences.
     From: Jonathan Glover (Introductions to Utilitarianism and its Critics [1990], Pt Five)
23. Ethics / E. Utilitarianism / 1. Utilitarianism
Satisfaction of desires is not at all the same as achieving happiness [Glover, by PG]
     Full Idea: Objections to utilitarianism as maximisation of preferences: faded past desires or the desires of the dead; obtaining desires and happiness are different; fewer desires are easier to satisfy; pain is good if it can be removed.
     From: report of Jonathan Glover (Introductions to Utilitarianism and its Critics [1990], Pt Two) by PG - Db (ideas)
23. Ethics / E. Utilitarianism / 5. Rule Utilitarianism
Rule-utilitarianism is either act-utilitarianism, or not really utilitarian [Glover]
     Full Idea: Rule-utilitarianism seems either to collapse into act-utilitarianism, or else it is only partly utilitarian.
     From: Jonathan Glover (Introductions to Utilitarianism and its Critics [1990], Pt Six)
24. Political Theory / A. Basis of a State / 2. Population / a. Human population
How can utilitarianism decide the ideal population size? [Glover]
     Full Idea: There are deep problems for utilitarianism in trying to work out what the ideal population size would be.
     From: Jonathan Glover (Introductions to Utilitarianism and its Critics [1990], Pt Four)
The sanctity of life doctrine implies a serious increase of abnormality among the population [Glover]
     Full Idea: Accepting views about the sanctity of life of the foetus commits us to a policy of drastically increasing the proportion of the population who are seriously abnormal.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §11.7)
     A reaction: This is a utilitarian view, and one with which I sympathise. We can't steamroller women's feelings for some greater dream about humanity, but the larger picture is vital to the discussion.
24. Political Theory / D. Ideologies / 6. Liberalism / g. Liberalism critique
Autonomy favours present opinions over future ones, and says nothing about the interests of potential people [Glover]
     Full Idea: Respect for autonomy seems to give priority to decisions based on your present outlook, even if your future outlook will be quite different, and it gives no support for any sort of paternalism, or for considering the interests of potential people.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §5.3)
     A reaction: The first point does give a plausible justification for paternalism. Potential people are not a problem if respect for autonomy is not the only valuable thing. We presumably desire that future humans will be autonomous.
If a whole community did not mind death, respect for autonomy suggests that you could kill them all [Glover]
     Full Idea: If you found a whole community who did not mind dying (because it is no more to regret than going to sleep), then according to the autonomy principle there would be no objection to killing the whole community.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §5.3)
     A reaction: I presume you would at least ask them if they desired death! They might regret being put to sleep. And respect for autonomy need not be the only value.
25. Social Practice / A. Freedoms / 5. Freedom of lifestyle
Autonomy seems to acquire greater weight when the decision is more important to a person [Glover]
     Full Idea: The appeal to autonomy has much more force where the person's decision is of great importance to them (as in suicide), than it has when it concerns a lesser decision (such as whether to wear a seatbelt).
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §13.5)
     A reaction: This is presumably uncontroversial. Planning regulations show the intrusiveness on an individual is crucial. I trim your hedge, or your hair, or your tonsils, or your beliefs…
25. Social Practice / C. Rights / 2. Moral rights
Being alive is not intrinsically good, and there is no 'right to life' [Glover]
     Full Idea: There is nothing intrinsically good in a person being alive, and the idea of a 'right to life' should be rejected.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §11.1)
     A reaction: If pleasure or benefit can be intrinsically good, I don't see why life can't be. The notion of a 'natural' or 'self-evident' right does look dubious to me. Rights are earned and given. Robinson Crusoe has no rights.
You can't have a right to something you can't desire, so a foetus has no 'right' to life [Glover]
     Full Idea: It seems that the bearers of rights must at least have the capacity to desire what they have a right to, which is something the foetus does not have.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §9.4)
     A reaction: Obviously we could say a person has a right to something they don't desire (such as freedom). How about: a mental defective has the right not to be laughed at, even if they don't understand the mockery?
25. Social Practice / F. Life Issues / 1. Causing Death
Utilitarians object to killing directly (pain, and lost happiness), and to side-effects (loss to others, and precedents) [Glover]
     Full Idea: Utilitarians have two direct objections to killing (the fear and pain, and the loss of future happiness), and two concerns about side-effects (the loss to friends and community, and the bad precedent and public anxiety caused).
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §4.4)
     A reaction: This invites obvious counterexamples, of somewhat unhappy, lonely people, who can be quietly killed with no qualms. Who will be callous enough to do this deed for us?
What is wrong with killing someone, if another equally worthwhile life is substituted? [Glover]
     Full Idea: If the only objection to killing (or not conceiving) is the impersonal one of not reducing the amount of worthwhile life, there seems nothing wrong with eliminating one worthwhile life if another is substituted.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §11.1)
     A reaction: This invites us to value a life in itself, rather than for what it makes possible (e.g. 'worthwhile' activity). It doesn't follow that the life is 'sacred' - only that it has some intrinsic value. And why not?
The 'no trade-off' position: killing is only justified if it prevents other deaths [Glover]
     Full Idea: The 'no trade-off' position: killing may be justified if it prevents other deaths, but not in defence of the quality of other lives, or by the miserable life of the person killed.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §12.2)
     A reaction: As a utilitarian, Glover opposes this, since death is not the only source of unhappiness. Would we (if necessary) kill a terrorist who was burning down all our art galleries or churches? I would, if it was the only way.
If someone's life is 'worth living', that gives one direct reason not to kill him [Glover]
     Full Idea: I am arguing that, if someone's life is worth living, this is one reason why it is directly wrong to kill him.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §3.7)
     A reaction: This is an attempt to find a modern utilitarian criterion of value. A problem case would be someone for whom only sadism made their life worth living.
Societies spend a lot to save known persons, but very little to reduce fatal accidents [Glover]
     Full Idea: There is often a big discrepancy between what a society will spend on saving the life of a known person in peril, and what it will spend to reduce the future level of fatal accidents.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §16.3)
     A reaction: This is a good point in favour of utilitarian approaches, which ask for impersonal calculation (which presumably embody an ideal of justice, buried somewhere in utilitarianism). But it isn't just 'sentimentality'.
25. Social Practice / F. Life Issues / 2. Euthanasia
Involuntary euthanasia is wrong because it violates autonomy, and it has appalling side-effects [Glover]
     Full Idea: Involuntary euthanasia can normally be ruled out, because it falls foul of the autonomy objection, and it is likely to have appalling side-effects.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §15.1)
     A reaction: The only defence of it is if the prospects are utterly horrible and the subject cannot grasp them. However, is this true of children or the very old. Paternalism may be appropriate, if the decider has reliably depressing knowledge?
Euthanasia is voluntary (patient's wish), or involuntary (ignore wish), or non-voluntary (no wish possible) [Glover]
     Full Idea: Voluntary euthanasia is done at the request of the person themselves. Involuntary euthanasia is killing someone in their own interests, but disregarding views they could express. Non-voluntary euthanasia is killing someone who cannot express any views.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §15.1)
     A reaction: Seems a clear and satisfactory distinction, despite the possibility of borderline cases. A look of pain on a face? An inarticulate person? Deliberate ambiguity? Misunderstanding?
Maybe extreme treatment is not saving life, but prolonging the act of dying [Glover]
     Full Idea: It is often suggested that medical intervention which goes beyond easing pain or distress is not saving life but 'prolonging the act of dying'.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §15.6)
     A reaction: This is an important idea to keep in mind, but still a very difficult call to make. It needs to be presented to those who fight for life, at any cost in money, time, medical resources, or suffering. May people probably give up unnecessarily.
The Nazi mass murders seem to have originated in their euthanasia programme [Glover]
     Full Idea: It is argued that the mass murders of the Nazi period had their small beginnings in the Nazi euthanasia programme.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §14.2)
     A reaction: This is the 'slippery slope' problem, and it seems undeniable that killing gets easier as you do more of it (e.g. on a farm). But not all slopes are slippery, if the focus is retained on reasons and justifications.
25. Social Practice / F. Life Issues / 3. Abortion
How would we judge abortion if mothers had transparent wombs? [Glover]
     Full Idea: How would we react to abortion if mothers had transparent wombs, so that foetuses were visible?
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §9.3)
     A reaction: Nice. Ultrasound scans have done this. The feeling of 'quickening' has always made a difference. Should these empathies affect our judgements?
Conception isn't the fixed boundary for a person's beginning, because twins are possible within two weeks [Glover]
     Full Idea: It is suggested that conception cannot be the boundary for the beginning of a genetic person, because monozygotic twins can split at any time during the first two weeks.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §9.3)
     A reaction: Interesting, but not convincing. If I suddenly learned that I could fission into twins tomorrow, I would be no less of a single person today.
If killing is wrong because it destroys future happiness, not conceiving a happy child is also wrong [Glover]
     Full Idea: The main utilitarian objection to killing (that it results in the loss of future years of happiness) seems an equally powerful objection to deliberately not conceiving a happy child.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §4.4)
     A reaction: This makes perfect sense, unless you give intrinsic value to existing lives, but none at all to potential lives. Virtue ethics helps here, but genetic engineering is a nightmare for Aristotle.
Defenders of abortion focus on early pregnancy, while opponents focus on later stages [Glover]
     Full Idea: Defenders of at least some abortions tend to focus on the early stages of pregnancy, when an embryo is very different from a baby, while opponents tend to focus on the later stages of pregnancy, when abortion resembles infanticide.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §9)
     A reaction: Seems true. If we ask which part of pregnancy we should focus on, the only plausible picture seems to be 'all of it', despite the confusing picture which results.
If abortion is wrong, it is because a foetus is a human being or a person (or potentially so) [Glover]
     Full Idea: The case against abortion rests either on the claim that the foetus is a human being (or a potential human being), or on the different claim that the foetus is a person (or potential person).
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §9)
     A reaction: The obvious problem with 'potential' is that every time Jack meets Jill there is a potential birth. And an early foetus is barely human, and clearly not a person.
If abortion is wrong because of the 'potential' person, that makes contraception wrong too [Glover]
     Full Idea: It is hard to see how the 'potential' argument can succeed against abortion without also succeeding against contraception.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §9.2)
     A reaction: It would even make it wrong not to introduce a given man to a given woman, if you thought they might be attracted! Maybe 'incipient' would be a better word than 'potential'? A person has been 'initiated'? Do words matter that much?
Abortion differs morally from deliberate non-conception only in its side-effects [Glover]
     Full Idea: Abortion differs morally from deliberate non-conception only in its side-effects.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §11.4)
     A reaction: This conclusion follows from a denial of any intrinsic value to a foetus, which in turns seems to imply that an adult human has no intrinsic value. Something must have intrinsic value, or nothing has any value at all.
If viability is a test or boundary at the beginning of life, it should also be so for frail old people [Glover]
     Full Idea: Supporters of the theory that 'viability' is the boundary at one end of life have to explain why it is not equally relevant at the other end.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §9.3)
     A reaction: A very nice problem for what looks at first like an intuitively good test. Someone dependent on a dialysis machine is not 'viable'. Before modern medicine, this objection was much less forceful. But I'm not 'viable' if I have to be fed.
Apart from side effects, it seems best to replace an inadequate foetus with one which has a better chance [Glover]
     Full Idea: If a foetus or baby has a poor chance of a worthwhile life, it may be directly wrong not to replace it by a baby with a better chance - though this consideration may be outweighed by side-effects.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §11.1)
     A reaction: I can't disagree with this. In early pregnancy, if we object to termination, why can't we object if the more 'worthwhile' child is not conceived. We want good human lives.
It is always right for a qualified person to perform an abortion when requested by the mother [Glover]
     Full Idea: I think it is always right for a qualified person capable of performing an abortion to do so when requested by the mother.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §11.4)
     A reaction: There seems to be a question if the father is vehemently opposed. Glover concedes the right of a doctor to refuse. What if it is late in pregnancy, the baby will be instantly adopted, and the mother's motive seems malicious?

One test for a worthwhile life is to assess the amount of life for which you would rather be unconscious [Glover]
     Full Idea: One test for a worthwhile life is to assess the amount of life for which you would rather be unconscious.
     From: Jonathan Glover (Causing Death and Saving Lives [1977], §13.2)
     A reaction: A nicely chilling question. Enthusiasts want never to sleep. If I would prefer to be unconscious 20 hours every day (for a long period), there doesn't seem much point, does there?

Colours arise from the rarity, density and mixture of matter [Digby]
     Full Idea: The origin of all colours in bodies is plainly deduced out of the various degrees of rarity and density, variously mixed and compounded.
     From: Kenelm Digby (Two treatises [1644], I.29.4), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 22.5
     A reaction: We are still struggling with this question, though I think the picture is gradually become clear, once you get the hang of the brain. Easy! See Idea 17396.
