| 4913 | Brain lesions can erase whole categories of perception, suggesting they are hard-wired [Carter,R] |
| Full Idea: The discovery that a single brain lesion can erase all knowledge of man-made artefacts, or all knowledge of animals, suggests that these categories somehow hard-wired into the brain - that we all have a set of 'memory pigeonholes'. | |
| From: Rita Carter (Mapping the Mind [1998], p.190) | |
| A reaction: Presumably something can become 'hard-wired' through experience, rather than from birth. The whole idea of 'hard-wired' seems misleading about the brain. What matters is that the brain physically constructs categories. |
| 20146 | 'Luck' is the unpredictable and inexplicable intersection of causal chains [Kekes] |
| Full Idea: 'Luck' is loose shorthand. It stands for various causal chains that intersect and whose intersection we can neither predict nor explain, because we lack the relevant knowledge. | |
| From: John Kekes (The Human Condition [2010], 01.2) | |
| A reaction: Aristotle's example is a chance meeting in the market place. The point about 'intersection' seems good, since luck doesn't seem to arise for an event in isolation. |
| 4910 | Sense organs don't discriminate; they reduce various inputs to the same electrical pulses [Carter,R] |
| Full Idea: Despite their variety, each sense organ translates its stimulus into electrical pulses; rather than discriminating one type of input from another, the sense organs actually make them more alike. | |
| From: Rita Carter (Mapping the Mind [1998], p.174) | |
| A reaction: An illuminating observation, which modern 'naïve realists' should bear in mind. Secondary qualities are entirely unrelated to the nature of the input, and are merely 'what the brain decides to make of it'. Discrimination is in our neurons. |
| 4911 | The recognition sequence is: classify, name, locate, associate, feel [Carter,R, by PG] |
| Full Idea: The sequence of events in the brain for perceptual recognition is first identifying a rough class for the object, then a name, then a location, then some associations, and finally an emotion. | |
| From: report of Rita Carter (Mapping the Mind [1998], p.181) by PG - Db (ideas) | |
| A reaction: This seems to be one of those places where neuro-science trumps philosophy. You can't argue with empirical research, so philosophical theories had better adapt themselves to this sequence. The big modern discovery is the place of emotion in recognition. |
| 4919 | There seems to be no dividing line between a memory and a thought [Carter,R] |
| Full Idea: It has become clear from research that there is no clear dividing line between a memory and a thought. | |
| From: Rita Carter (Mapping the Mind [1998], p.308) | |
| A reaction: This always struck me as an obvious criticism of Descartes, when he claimed that memory was not an essential part of the 'thinking thing'. How can you think or understand without memory of the different phases of your thoughts? No memory, no mind! |
| 4908 | No one knows if animals are conscious [Carter,R] |
| Full Idea: No one knows if animals are conscious. | |
| From: Rita Carter (Mapping the Mind [1998], p.155) | |
| A reaction: This is a report from the front line of brain research, and should be born in mind when over-confident people make pronouncements about this topic. It strikes me as important to grasp that animals MIGHT not be conscious. |
| 4902 | Pain doesn't have one brain location, but is linked to attention and emotion [Carter,R] |
| Full Idea: Scans show there is no such thing as a pain centre; pain springs mainly from the activation of areas associated with attention and emotion. | |
| From: Rita Carter (Mapping the Mind [1998], p. 12) | |
| A reaction: Most brain research points to the complex multi-layered nature of experiences that were traditionally considered simple. We can be distracted from a pain, and an enormous number of factors can affect our degree of dislike of a given pain. |
| 4904 | Proper brains appear at seven weeks, and neonates have as many neurons as adults do [Carter,R] |
| Full Idea: The main sections of the brain, including the cerebral cortex, are visible within seven weeks of conception, and by the time the child is born the brain contains as many neurons - about 100 billion - as it will have as an adult. | |
| From: Rita Carter (Mapping the Mind [1998], p. 17) | |
| A reaction: Of interest in the abortion debate, and also in thinking about personal identity. However, it seems clear that the number of connections, rather than neurons, is what really matters. A small infant may well lack personal identity. |
| 4915 | In primates, brain size correlates closely with size of social group [Carter,R] |
| Full Idea: Brain size in primates is closely associated with the size of the social group in which the animal lives. | |
| From: Rita Carter (Mapping the Mind [1998], p.257) | |
| A reaction: Intriguing. Humans can have huge social groups because of language, which suggests a chicken-or-egg question. Language, intelligence and size of social group must have expanded together in humans. |
| 4917 | Consciousness involves awareness, perception, self-awareness, attention and reflection [Carter,R] |
| Full Idea: Awareness, perception, self-awareness, attention and reflection are all separate components of consciousness, and the quality of our experience varies according to which and how many of them are present. | |
| From: Rita Carter (Mapping the Mind [1998], p.300) | |
| A reaction: Philosophers like to emphasise 'qualia' and 'intentionality'. This remark slices the cake differently. 'Attention' is interesting, dividing consciousness into two areas, with some experience fading away into the darkness. Hume denied self-awareness. |
| 4916 | There is enormous evidence that consciousness arises in the frontal lobes of the brain [Carter,R] |
| Full Idea: A huge volume of evidence suggests that consciousness emerges from the activity of the cerebral cortex, and in particular from the frontal lobes. | |
| From: Rita Carter (Mapping the Mind [1998], p.298) | |
| A reaction: Dualists must face up to this, and even many physicalists have a rather vague notion about the location of awareness, but we are clearly homing in very precise physical substances which have consciousness as a feature. |
| 4905 | Normal babies seem to have overlapping sense experiences [Carter,R] |
| Full Idea: Connections in a baby's brain probably give the infant the experience of 'seeing' sounds and 'hearing' colours - which occasionally continues into adulthood, where it is known as 'synaesthesia'. | |
| From: Rita Carter (Mapping the Mind [1998], p. 19) | |
| A reaction: A fact to remember when discussing secondary qualities, and the relativism involved in the way we perceive the world. If you have done your philosophy right, you shouldn't be surprised by this discovery. |
| 4918 | In blindsight V1 (normal vision) is inactive, but V5 (movement) lights up [Carter,R] |
| Full Idea: Scans show that a sub-section of the visual cortex called V5 - the area that registers movement - lights up during blindsight, even though V1 - the primary sensory area that is essential for normal sight - is not active. | |
| From: Rita Carter (Mapping the Mind [1998], p.307) | |
| A reaction: The whole point of blindsight is to make us realise that vision involves not one module, but a whole team of them. The inference is that V1 involves consciousness, but other areas of the visual cortex don't. |
| 4912 | Out-of-body experiences may be due to temporary loss of proprioception [Carter,R] |
| Full Idea: Out-of-body experiences may be due to temporary loss of proprioception. | |
| From: Rita Carter (Mapping the Mind [1998], p.187) | |
| A reaction: This is only a speculation, but it is an effect which can be caused by brain injury, and dualists should face the possibility that this evidence (prized by many dualists) can have a physical explanation. |
| 4903 | Scans of brains doing similar tasks produce very similar patterns of activation [Carter,R] |
| Full Idea: The pattern of brain activation during, say, a word retrieval task is usually similar enough among the dozen or so participants who typically take part in such studies for their scans to be overlaid and still show a clear pattern. | |
| From: Rita Carter (Mapping the Mind [1998], p. 17) | |
| A reaction: This doesn't surprise me, though it could be interpreted as supporting type-type identity, or as supporting functionalism. Armstrong and Lewis endorse a sort of reductive functionalism which would fit this observation. |
| 4920 | Thinking takes place on the upper side of the prefrontal cortex [Carter,R] |
| Full Idea: The nuts and bolts of thinking - holding ideas in mind and manipulating them - takes place on the upper side of the prefrontal cortex. | |
| From: Rita Carter (Mapping the Mind [1998], p.312) | |
| A reaction: Keep this firmly in view! Imagine that the skull is transparent, and brain activity moves in waves of colour. Dualism would, in those circumstances, never have even occurred to anyone. |
| 4906 | Babies show highly emotional brain events, but may well be unaware of them [Carter,R] |
| Full Idea: Babies show emotion dramatically, but the areas of the brain that in adults are linked to the conscious experience of emotions are not active in newborn babies. Such emotions may therefore be unconscious. | |
| From: Rita Carter (Mapping the Mind [1998], p. 19) | |
| A reaction: Traditionally, 'unconscious emotion' is a contradiction, but I think we should accept this new evidence and rethink the nature of mind. Not only might emotion be non-conscious, but we should even consider that rational thinking could be too. |
| 4909 | The only way we can control our emotions is by manipulating the outside world that influences them [Carter,R] |
| Full Idea: We try to manipulate our emotions all the time, but all we are doing is arranging the outside world so it triggers certain emotions - we cannot control our reactions directly. | |
| From: Rita Carter (Mapping the Mind [1998], p.155) | |
| A reaction: This seems to me to throw a very illuminating light on a huge amount of human behaviour, such as going to the cinema or listening to music. The romantic movement encouraged direct internal manipulation. Compare sex fantasies with viewing pornography. |
| 4914 | A frog will starve to death surrounded by dead flies [Carter,R] |
| Full Idea: A frog will starve to death surrounded by dead flies. | |
| From: Rita Carter (Mapping the Mind [1998], p.195) | |
| A reaction: A nice warning against assuming that rationality is operating when a frog feels hungry and 'decides' to have lunch. We should take comfort from the fact that humans are NOT this stupid, and philosophers should try to accurately describe our gift. |
| 20169 | An action may be intended under one description, but not under another [Kekes] |
| Full Idea: People can usually be described as intending an action under one description, but not under another. ...Consequently the same action may reasonably be said to be both intentional and unintentional. | |
| From: John Kekes (The Human Condition [2010], 07.2) | |
| A reaction: This is the terrorist/freedom fighter problem. The problem seems to arise with long-term intentions, rather than immediate ones. Maybe it is the significance of the intention, rather than the intention itself? |
| 20149 | To control our actions better, make them result from our attitudes, not from circumstances [Kekes] |
| Full Idea: We increase our control by making our actions more and more the effects of our attitudes, and less and less the effects of external forces acting on us independently of our attitudes. | |
| From: John Kekes (The Human Condition [2010], 02.4) | |
| A reaction: He says that the attitudes should be focused on our well-being. Attitudes may also, however, serve some exernal ideal, such as altruism or patriotism. He has built a case for 'control' being a much more important value than 'free will'. |
| 19738 | Values are an attempt to achieve well-being by bringing contingencies under control [Kekes] |
| Full Idea: Our system of values should be understood, among other things, as our attempt to cope with contingencies by making the connection between our well-being and actions less contingent and more within our control. | |
| From: John Kekes (The Human Condition [2010], Intro) | |
| A reaction: He gives an account in which every aspect of morality focuses on human well-being. Of course, the values will dictate what constitutes that well-being, as well as good means of attaining it. |
| 20145 | Values help us to control life, by connecting it to what is stable and manageable [Kekes] |
| Full Idea: Values are ...an attempt to cope with contingencies by making the connection between our well-being and actions less contingent and more within our control. | |
| From: John Kekes (The Human Condition [2010], Intro) | |
| A reaction: This sounds more like principles than values, since the former tell you what to do, but a value in itself is just a picture of possibilities. |
| 20170 | Responsibility is unprovoked foreseeable harm, against society, arising from vicious character [Kekes] |
| Full Idea: Full responsibility is when evil-doers can fully foresee the harm that results, their victims have not provoked it, it violates the requirements of physical protection in a society, the action reflects character, and it is viciously motivated. | |
| From: John Kekes (The Human Condition [2010], 07.4) | |
| A reaction: [compressed] The point of this is to omit any reference to an explicit intention to perform an evil act. The Nazi Franz Stangl claimed that he never intended evil, but Kekes says that if true he is innocent, but the above definition makes him guilty. |
| 20165 | Reason and morality do not coincide; immorality can be reasonable, with an ideology [Kekes] |
| Full Idea: A central assumption of Western moral thought is mistaken: the requirements of reason and morality do not coincide. Immorality need not be unreasonable. ...Malevolent motives in combination with ideologies supply reasons for doing evil. | |
| From: John Kekes (The Human Condition [2010], 06.5) | |
| A reaction: I presume that Kant would say the malevolent motives are irrational. If I perform an evil act because someone gives me a stupid reason for doing it, I am not thereby rational because I am acting for a reason. Wrong. |
| 20171 | Practical reason is not universal and impersonal, because it depends on what success is [Kekes] |
| Full Idea: The assumption that the requirements of reason are universal and impersonal ...is false of practical reason that aims at successful action. Whether a belief is true depends on the facts. Whether an action is successful depends on what success consists in. | |
| From: John Kekes (The Human Condition [2010], 08.5) | |
| A reaction: Kekes is trying to eliminate the Kantian idea that reason can lead us to the 'right' thing to do. He rightly points to the complex demands of human, cultural and personal values. |
| 20175 | If morality has to be rational, then moral conflicts need us to be irrational and immoral [Kekes] |
| Full Idea: The absurdity follows [from Kant's categorical imperative] that in the case of moral conflicts reason and morality require us to act irrationally and immorally. | |
| From: John Kekes (The Human Condition [2010], 10.4) | |
| A reaction: We can't pick one from two equals if we must have a reason for the preference, but that does not make it 'irrational' to choose one of them, when it doesn't matter which one is chosen. Taking one of the cheese sandwiches is not irrational. |
| 20174 | Relativists say all values are relative; pluralists concede much of that, but not 'human' values [Kekes] |
| Full Idea: We must distinguish between pluralism and relativism about values. Pluralists accept that the validity of cultural and personal values is relative to societies and individuals. But they also hold that human values are objectively valid. | |
| From: John Kekes (The Human Condition [2010], 09.4) | |
| A reaction: This is a very attractive response to global moral relativism. I see a problem in the neat division into three distinct forms of value. Each of the three sets of values ought to be sensitive to the other two areas. Humans are cultured individuals. |
| 20159 | Cultural values are interpretations of humanity, conduct, institutions, and evaluations [Kekes] |
| Full Idea: I distinguish four types of cultural values likely to be found in a particular society: interpretations of human values; forms of expression and conduct; institutions and practices within them; and modes of evaluation. | |
| From: John Kekes (The Human Condition [2010], 05.2) | |
| A reaction: He proceeds to enlarge on these four. This sub-divides the second of his three main areas of value. I like philosophers who do that sort of thing. It gives you the reassuring feeling that you can break a problem down into elements we understand.... |
| 20161 | The big value problems are evil (humanity), disenchantment (cultures), and boredom (individuals) [Kekes] |
| Full Idea: The major problem for the human dimension of values is the prevalence of evil; for the cultural dimension it is widespread disenchantment; and for the personal dimension it is pervasive boredom. | |
| From: John Kekes (The Human Condition [2010], 05.5) | |
| A reaction: Boldly simple claims, but quite persuasive. Presumably it is the evil in human beings, rather than natural evil (like earthquakes) that is the problem. Disenchantment must come through alienation from social values. Powerlessness, rather than boredom? |
| 20156 | We are bound to regret some values we never aspired to [Kekes] |
| Full Idea: We inevitably feel regret for the many values we could have, but did not, try to realize. | |
| From: John Kekes (The Human Condition [2010], 04.5) | |
| A reaction: He's obviously talking about working harder at our projects. |
| 20150 | There are far more values than we can pursue, so they are optional possibilities [Kekes] |
| Full Idea: A significant feature of our system of values is that it provides many more values than we could pursue. ...We encounter values as possibilities, and we must accept or reject them. | |
| From: John Kekes (The Human Condition [2010], 03.1) | |
| A reaction: This immediately invites the lovely question of what values you are going to invoke when you discriminate among the values available in your culture. Nietzsche says it comes down to 'taste'. |
| 20158 | Innumerable values arise for us, from our humanity, our culture, and our individuality [Kekes] |
| Full Idea: There is an irreducible plurality of values that follow from the universal requirements of human well-being, from a shared cultural identity, and from individual conceptions of well-being. | |
| From: John Kekes (The Human Condition [2010], 05 Intro) | |
| A reaction: This strikes me as a very helpful division. It seems reasonably obvious, but I have not encountered it elsewhere. It is an obvious foundation for international negotiations. We can criticise another culture by appealing to human values. |
| 20151 | Our attitudes include what possibilities we value, and also what is allowable, and unthinkable [Kekes] |
| Full Idea: The beliefs, emotions, motives, and desires that form our attitudes ...include not only what possibilities we value, but also the limits we should not transgress. ...The strongest limit is what I call 'the unthinkable'. | |
| From: John Kekes (The Human Condition [2010], 03.2) | |
| A reaction: Another chance to link to my favourite idea from Democritus! Ideally we want a theory which shows how a vision of the possibilities immediately points to the limits, and to what is unthinkable. |
| 20152 | Unconditional commitments are our most basic convictions, saying what must never be done [Kekes] |
| Full Idea: Unconditional commitments are the most basic convictions we have. They tell us what we must not do no matter what, what we regard as outrageous, horrible, beyond the pale, or, in religious language, as sacrilegious. | |
| From: John Kekes (The Human Condition [2010], 03.3) | |
| A reaction: The Aztecs should have made rather different unconditional commitments from the ones they ended up with. How do you persuade someone to make such an unconditional commitment. Abortion seems to involve huge clashes here. |
| 20153 | Doing the unthinkable damages ourselves, so it is more basic than any value [Kekes] |
| Full Idea: Doing the unthinkable causes deep, often irreparable, damage to our sense of ourselves. ...That is why the unthinkable indicates a more basic commitment than what we have to any value. | |
| From: John Kekes (The Human Condition [2010], 03.3) | |
| A reaction: Kekes makes the interesting claim that what is unthinkable is so basic that it doesn't even count as a value - it is more like a fact of your own nature, which is prior to your values. Not sure about that. |
| 20162 | Evil isn't explained by nature, by monsters, by uncharacteristic actions, or by society [Kekes] |
| Full Idea: Four inadequate explanations of human evil attribute it to natural causes, moral monsters, uncharacteristic actions, and corrupting social conditions. | |
| From: John Kekes (The Human Condition [2010], 06.3) | |
| A reaction: He is addressing the 'secular problem of evil', which arises if you assume that human beings are essentially good, and then look around you. He says evil explains corrupting social conditions, so we can't be circular about it. |
| 20157 | Well-being needs correct attitudes and well-ordered commitments to local values [Kekes] |
| Full Idea: A reasonable conception of well-being requires mistake-free attitudes and well-ordered commitments to some values selected from our society's system of values. | |
| From: John Kekes (The Human Condition [2010], 05 Intro) | |
| A reaction: This summarises where he has got to so far. |
| 20154 | Control is the key to well-being [Kekes] |
| Full Idea: Increasing control is the key to our well-being. | |
| From: John Kekes (The Human Condition [2010], 04 Intro) | |
| A reaction: This slogan emerges from a sustained discussion. Hitler and Stalin increased control rather impressively, so we obviously need a bit more than this to get proper well-being. There's also something to be said for going with the flow. |
| 4907 | The 'locus coeruleus' is one of several candidates for the brain's 'pleasure centre' [Carter,R] |
| Full Idea: Noradrenaline is an excitatory chemical that induces physical and mental arousal and heightens mood. Production is centred in an area of the brain called the locus coeruleus, which is one of several candidates for the brain's 'pleasure' centre. | |
| From: Rita Carter (Mapping the Mind [1998], p. 30) | |
| A reaction: It seems to me very morally desirable that people understand facts of this kind, so that they can be more objective about pleasure. Pleasure is one cog in the machine that makes a person, not the essence of human life. |
| 20172 | Boredom destroys our ability to evaluate [Kekes] |
| Full Idea: The threat of boredom is the dissolution of the evaluative dimension of our life. | |
| From: John Kekes (The Human Condition [2010], 09.1) | |
| A reaction: This seems right. If nothing is interesting, then there is no scale of values left, except perhaps 'of possible interest to other people'. |
| 20173 | Boredom is apathy and restlessness, yearning for something interesting [Kekes] |
| Full Idea: Boredom combines apathy and restlessness. ...We crave stimulation, worthwhile activities, and objects that engage our interest. | |
| From: John Kekes (The Human Condition [2010], 09.1) |
| 20155 | Society is alienating if it lacks our values, and its values repel us [Kekes] |
| Full Idea: We feel estranged from our society if the values we prize are not available, and if we do not want to live by the available values. | |
| From: John Kekes (The Human Condition [2010], 04.4) | |
| A reaction: There are two pictures here, for a monolithic culture, and for pluralism. For example, the values of Islam are fairly available in the Christian/atheist UK - but not sharia law. Pluralism can embrace a huge array of moderate values, but not extremes? |
| 20164 | The ideal of an ideology is embodied in a text, a role model, a law of history, a dream of the past... [Kekes] |
| Full Idea: The ideal in an ideology may be set down in a sacred text, exemplified in an exceptional life, dictated by laws of history, sociology, or psychology, located in a past uncorrupted idyllic past, or in a future Utopia of perfected human nature, and so on. | |
| From: John Kekes (The Human Condition [2010], 06.4) | |
| A reaction: A bit grumpy, but a fair observation about an awful lot of slightly mad social endeavours. |
| 20163 | Ideologies have beliefs about reality, ideals, a gap with actuality, and a program [Kekes] |
| Full Idea: Ideologies have a set of beliefs about the world, an ideal of life, an explanation of the gap between the ideal and actuality, and a program for closing the gap. | |
| From: John Kekes (The Human Condition [2010], 06.4) | |
| A reaction: [compressed] Kekes emerges as a bit right of centre in his politics. He clearly despises such ideologies, yet his book is an optimistic program for correcting things. Maybe the enemy is dogmatic ideologies. Kekes gives an undogmatic account of values. |
| 23104 | Dworkin believed we should promote equality, to increase autonomy [Dworkin, by Kekes] |
| Full Idea: Egalitarians believe that most often it is by promoting equality that autonomy is increased; this is the egalitarianism of such liberals as Ronald Dworkin. | |
| From: report of Ronald Dworkin (Taking Rights Seriously [1977]) by John Kekes - Against Liberalism 05.1 | |
| A reaction: Not my idea of equality. The whole point is to ascribe reasonable equality to everyone, including those with a limited capacity for autonomy. Equality is a consequence of universal respect. |
| 23257 | We can treat people as equals, or actually treat them equally [Dworkin, by Grayling] |
| Full Idea: Dworkin distinguishes between treating people as equals, that is, 'with equal concern and respect', and treating them equally. This latter can be unjust. | |
| From: report of Ronald Dworkin (Taking Rights Seriously [1977]) by A.C. Grayling - The Good State 2 | |
| A reaction: The big difference I see between them is that the first is mere words, and the second is actions. Cf. 'thoughts and prayers' after US school shootings. How about equal entitlements, all things being equal? |
| 18621 | Treating people as equals is the one basic value of all plausible political theories [Dworkin, by Kymlicka] |
| Full Idea: Dworkin suggests that every plausible political theory has the same ultimate value, which is equality - in the more abstract and fundamental sense of treating people 'as equals'. | |
| From: report of Ronald Dworkin (Taking Rights Seriously [1977], 179-83) by Will Kymlicka - Contemporary Political Philosophy (1st edn) | |
| A reaction: I associate this idea with Kant (who says they are equal by virtue of their rationality), so that's a pretty influential idea. I would associate the main challenge to this with Nietzsche. |
| 20148 | Equal distribution is no good in a shortage, because there might be no one satisfied [Kekes] |
| Full Idea: It is useless to distribute insufficient resources equally, because the equal distribution of insufficient resources may result in the even worse outcome that no one's reasonable expectations are met. | |
| From: John Kekes (The Human Condition [2010], 01.5) | |
| A reaction: He gives a shortage of oxygen tanks as a persuasive example, but that is hardly typical of the sorts of things that we normally want to distribute. |
