notes to condense later:
Chapter 1: About ethics
-Argues that our moral intuitions are a product of natural selection. pg. 5 "We have inherited a set of moral intuitions from our ancestors. Now we need to work out which of them should be changed.
-This latter bit seems a bit problematic to me. On what basis can we reason about/revise these intuitions without an appeal to a natural law? How do we go from an "is" to an "ought"?
-Singer agrees that moral intuitions are subjective in the sense that they are not natural kinds that exist independently of human observers. But he still believes that we can reason about these intuitions. P.g. 8 "the denial of objective ethical facts does not imply the rejection of ethical reasoning".
-After a brief analysis, Singer concludes that our intuitions about ethics are tied up with notions of justifiability and universalism. Someone is living according to an ethical standard if they can justify their actions to others (Scanlon), and if the reasons they give are not selfish but take others into account. On the basis of justifiability and universalism we will use reason to modify our ethical intuitions.
-Singer notes that most major ethical theories take this universal stance, although they sometimes conflict with each other because they are maximizing different things across people (happiness, preferences, rights, etc.). As a simple starting point, Singer adopts "preference utilitarianism" - satisfying the preferences of the most people.
-The lacuna in Singer's argument in this chapter, I think, is the basis of putting justifiability and universalism on a pedestal above all our other moral intuitions. An answer might be that we intuitively feel that these are our most important and fundamental intuitions (+ this feeling itself is a product of our biology). This rescues us from appealing to something "outside" or "above" our inherited oughts. We inherent a constellation of moral intuitions, and intuitively recognize some as more important than others. These become the axioms that guide our moral reasoning.
Chapter 2: Equality and its implications
-On what basis can we claim that all humans are equal? We obviously differ in physical, intellectual, + moral competence.
-Singer argues that equality fall out of our intuition that our moral judgements should be universal, not selfish (i.e., considering the preferences of others).
-Thus, agents are equal (in terms of the moral consideration that they should be given), so long as they have preferences. Pg. 21 "The principle of equal consideration of interests prohibits making our readiness to consider the interests of others depend on their abilities or other characteristics, apart from having interests."
-Equal consideration of interests provides a natural counter to discrimination based on supposed differences among racial groups or genders. Even if we suppose that there are differences in ability - and this is a big if - this is immaterial because we should be considering preferences, not ability (especially because achieving genetic and environmental equality is a pipe dream).
-This naturally leads to a principle "from each according to his ability, to each according to his need." Singer acknowledges that perfect realization of this principle is impractical, as those blessed with natural gifts and favorable conditions will strive to maintain their advantage, but suggests "we should try to create a climate of opinion" that will lead to a reduction in excessive disparities in resources (i.e., create a culture openly hostile to inequality - this may have started to emerge in the past few years)
-Interesting side note: argues that affirmative action is not in conflict with equal consideration of interests. Choosing based on race is no less arbitrary than choosing based on intelligence. The institution in each case is just trying to further certain goals, and so long as the institution is not rejecting applicants for reasons unrelated to these goals, then all applicants have been given due consideration, and we are just angry about changing goals.
Chapter 3: Equality for animals?
-Following the consequences of preference utilitarianism further, we see that it natural extends moral consideration to animals as well.
-If the chief point of consideration is whether an agent has interests, it seems that the number of legs and the presence of fur is just as immaterial as intelligence or strength.
-On one hand this is intuitively appealing: most of us have a natural empathy and affinity for animals. But at the same time this raises some troubling comparisons of moral worth, e.g., an infant newborn human vs a fully grown dog, the latter of which likely has a more fully developed and acute sense of preferences.
Chapter 4: What's wrong with killing?
-Singer next considers the morality of killing people. "People" are self aware beings with a capacity to imagine and desire particular futures. Most humans and a few animals are people. Consistent with his emphasis on preferences, Singer doesn't consider mere membership in homo sapiens a meaningful moral consideration.
-Both major flavors of utilitarianism conclude that killing people is particularly bad. For the preference utilitarian, it is a straightforward case of thwarting another's preferences (at least typically). For the hedonistic utilitarian, even though the effect on the person could be argued to be curiously morally neutral (because there is no pleasure or pain in non-existence), a culture in which wanton killing is permitted would be stressful for the extant future-loving persons. (Strangely, it seems this second argument could be recast in terms of preferences and apply equally to the preference utilitarian, which Singer does not address. Throughout the book, the distinction between preference and hedonistic utilitarianism often seems tenuous).
-What about killing sentient non-persons (e.g., a merely conscious animal)? For preferences utilitarians, killing here is not a moral violation. If a being cannot imagine its future, it can't have preferences about that future. A fish on the hook struggles out of a desire to escape confinement + avoid pain. It is not despairing over unfulfilled dreams. An instantaneous, painless death would not violate any of its preferences. Singer suggests that hedonistic utilitarianism runs into all kinds of hell here. One could argue that you are denying the animal its future pleasure (again, why not say future preferences???). However, this implies that our goal should be to increase the sum total happiness in the universe, which has the curious consequence of suggesting, for example, that all other things being equal, if we expect our children to have happy lives then we are morally impelled to have more. Alternatively, the view that we should only consider extant (not future) life suggests that it is fine to bring a severely disabled child (a sentient non-person) to term and then euthanize it.
-I think this rather academic digression, while interesting, falls out of a mistake in objective function. Why not argue for maximizing present and future average, not summed, happiness? This normalizes our metric to focus on the average person. We intuitively care about the happiness at the level of single persons, not a collective sum.
Chapter 5: Taking life: animals
-Singer explores the killing of non-person animals in more detail. For him, this is tied closely to questions of replaceability - to what extent are extant and potential beings all replaceable with each other - because many domestic animals only come into existence in the first place as replacements for their consumed ancestors.
-Hedonistic utilitarianism supports replaceability, because if you replace one happy animal with another, the sum total pleasure in the universe is conserved. However, valuing summed pleasure in this way has odd consequences, as we saw in the previous chapter.
-As we saw, preference utilitarianism is neutral on the painless killing of non-persons because no preferences are violated (by definition).
-A potential counter to Singer's thought is that preference utilitarianism runs into the same issue as hedonistic utilitarianism. If our goal is to maximize summed satisfied preferences, then we are under a moral obligation to replace the animal, and this has the odd consequence that we should maximize the number of lives (assuming preference satisfaction). Singer gets around this by proposing a normalization procedure of his own. Preference satisfaction should not be counted as a positive, but as a satisfaction of a negative debt. This raises all sorts of thorny questions about the value of existence (if we are all a little unsatisfied, is an empty universe preferable?) which Singer (self-admittedly) squirms his way out of by appending a generic value for life to preference utilitarianism.
-Anyway, the (unstated) consequence seems to be that killing a satisfied non-person leaves you with a neutral moral ledger, with an incentive for replacement due to our intrinsic appreciation of life.
Chapter 6: Taking life: the embryo and the fetus
-The conservative argument against abortion: (1) killing an innocent human being is wrong (2) a fetus is an innocent human being (3) therefore it is wrong to kill a fetus
-Most liberal positions do not tackle this argument head on, because if we deny that a fetus is a human being, it is difficult to identify a clear point at which it is one. Most liberal responses are practical arguments about abortions laws that are agnostic to the moral status of abortion itself (e.g., abortion laws just create unsafe illegal abortions, abortion is not of the government's business, etc.).
-Singer insists that we should focus not on the second premise, but on the first. As we have seen, membership in homo sapiens is not a relevant moral factor - the key moral considerations are consciousness, the capacity to feel pain (the most rudimentary preference), and personhood, which grants additional moral weight. Singer argues that once the fetus is sufficiently developed to feel pain, we should render unto it the same moral consideration as other conscious non-persons.
-Arguments based on the premise that it is wrong to kill potential persons are weak - theoretically, you have to justify why bringing persons into the world is intrinsically valuable (although note that Singer just argued this in the previous chapter), and practically, we act against this all the time (e.g., via artificial or natural birth control).
-Finally, Singer admits a rather uncomfortable consequence of his conclusions. Birth does not mark a meaningful landmark in the moral status of a human (the are conscious non-persons before and after birth). Singer suggests that, as a result, we may have to rethink our cultural taboo on infanticide.
-I'm not sure Singer's though puts us in as uncomfortable a spot as he suggests. Under utilitarianism, killing a person is especially morally weighty, but killing conscious non-persons is still not taken lightly, both due to the difficulty of painless, instant death and the effect that such acts have on others.
-The ethical conclusion offered by utilitarianism thus seems to be very permissive abortion laws for the 18 weeks before the fetus is likely conscious and judicious permission of abortion and infanticide after this point.
Chapter 12: Why act morally?
I.e, why should we base our decisions on moral considerations rather self-interested, cultural, or aesthetic ones?
There's an old line of thought in philosophy that argues that we should be ethical because to be ethical is to be rational. This is based on the observation that both rationality and ethics are rooted in universalizability. Proper logical reasoning is universally valid - a mathematical proof is not true for one person and false for another. Ethics involves universalizing our preferences, taking others into consideration and so basing our actions on principles that are acceptable to others. The problem is, obviously, that ethical universalizability is stricter than rational universalizability, so the two can't be so easily equated. A person acting out of conspicuous self-interest is not necessarily acting irrationally (e.g., in highly competitive environments where such behavior is the norm. Even if we had a better argument for why morality is rational, this just to seems to be a form of can-kicking - then we have to ask 'why be rational?' - an even trickier question.
A more intuitive answer is that behaving ethically is in our self-interest. Moral feelings seem to have evolved to help humans live cooperatively together, promoting the good of all and preventing exile. Critics argue that such thinking takes us out of the realm of ethics entirely, but Singer takes a dim view of this purist view. In practice, we seem to understand rationally (and feel deeply intuitively) that moral behavior is in our interest. But this doesn't mean that we go around weighing the personal benefit of moral behavior in every interaction. Rather, understanding that morality is important, we conceive ourselves as moral people (or at least as people trying to be moral), and then let that self conception guide our behavior on an intuitive level. This stance feels less Machiavellian.
Finally, Singer suggests that for many, striving for an ethical life can offer some existential satisfaction. People who we label as 'psychopaths' are unconcerned with anything past the immediate present and live their life accordingly, and apparently quite pleasantly. Most people aren't satisfied with a purpose as limited as the constant pursuit of immediate pleasure, and may find meaning in hobbies, sports, careerism, or the accumulation of wealth. Sounding a little like Rudolf Bultmann, Singer suggests that the pursuit of an ethical life is a particular useful source of meaning, since it allows us to transcend ourselves and shields us from the vicissitudes of our lives as imperfect, mortal creatures. There is calm in the universal perspective offered by ethics. He summarizes this prettily:
"I am now suggesting that rationality, in the broad sense that includes self-awareness and reflection on the nature and point of our own existence, may push us towards concerns broader than the quality of our own existence; but the process is not a necessary one, and those who do not take part in it are not irrational or in error. Some people find collecting stamps an entirely adequate way of giving purpose to their lives. There is nothing irrational about that; but others again seek something more significant as they become more aware of their situation in the world and more reflective about their purposes. To this third group, the ethical point of view offers a meaning and purpose in life that one does not grow out of."
