Culture War Roundup for the week of January 2, 2023

This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.

Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.

We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:

  • Shaming.

  • Attempting to 'build consensus' or enforce ideological conformity.

  • Making sweeping generalizations to vilify a group you dislike.

  • Recruiting for a cause.

  • Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.

In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:

  • Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.

  • Be as precise and charitable as you can. Don't paraphrase unflatteringly.

  • Don't imply that someone said something they did not say, even if you think it follows from what they said.

  • Write like everyone is reading and you want them to be included in the discussion.

On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

David Pearce, the most sympathetic of utilitarians and one of the smarter ones, bites the bullet here:

Reprogramming Predators

First, a cruelty-free world entails a transition to global veganism. Realistically, global veganism won't come about purely or even mainly via moral persuasion within any plausible timeframe. Such a momentous transition can occur only after the advent of mass-produced artificial meat ("Krea") that is at least as cheap, tasty and healthy as flesh from slaughtered factory-farmed animals - with moral argument playing a modest supporting role. For sure, there is still the "yuk factor" to overcome. But when delicious, cruelty-free cultured-meat products become commercially available, the "yuk factor" should actually work in favour of cultured meat - since meat from factory-farmed animals is not merely morally disgusting but often physically disgusting too.

However, this transition isn't enough. Even the hypothetical world-wide adoption of a cruelty-free diet leaves one immense source of suffering untouched. Here we shall explore one of the thorniest issues the end of suffering entails: the future of what biologists call obligate predators. For the abolitionist project seems inconsistent with one of our basic contemporary values. The need for species conservation is so axiomatic that an explicitly normative scientific sub-discipline, conservation biology, exists to promote it. In the modern era, the extinction of a species is usually accounted a tragedy, especially if that species is a prominent vertebrate rather than an obscure beetle. Yet if we seriously want a world without suffering, how many existing Darwinian life-forms can be conserved in their current guise? What should be the ultimate fate of iconic species like the large carnivores? True, only a minority of the Earth's species are carnivorous predators: the fundamental laws of thermodynamics entail that whenever there is an "exchange of energy" between one trophic level and another, there is a significant loss. The majority of the planet's 50,000 or so vertebrate species are vegetarian. But among the minority of carnivorous species are some of the best known creatures on the planet. Should these serial killers be permitted to prey on other sentient beings indefinitely?

A few forms of extinction are almost universally applauded even now. Thus the demise of the smallpox virus in the wild is wholly unlamented, though controversy persists over whether the last two pathogenic Variola copies in human custody should be destroyed. The virus could be recreated from scratch if needed. Technically, viruses aren't alive; they can't independently replicate. Yet the same welcome will be extended to the extinction of scores of bacterial pathogens that cause human disease if we can plot their eradication as efficiently as the two Variola variants that cause smallpox. Likewise, exterminating the five kinds of protozoan parasites of the genus Plasmodium that cause malaria would be almost entirely uncontentious; a human child dies from malaria on average every twelve seconds. ...

Most controversial of all, however, would be the extinction - or genetically-driven behavioural modification - of members of the cat family. We'll focus here on felines rather than the "easy" cases like parasitic tapeworms or cockroaches because of the unique status of members of the cat family in contemporary human culture, both as pets/companion animals and as our romanticised emblems of "wildlife". ...

It is worth stressing, repeatedly since the charge is made time and again, that this indictment of predators is not to blame a lion [or a domestic cat] for its behaviour. First, barring genetic engineering or freaks of nature, lions are obligate carnivores. Secondly, they don't understand the implications of what they are doing. Any mutant lion with a theory of mind capable of empathising with its prey would be rapidly outbred by "sociopathic" lions. Barring human intervention, a compassionate lion who rejected the "law of the jungle" would starve to death. Consequently so would its cubs. Lions are "sociopathic" towards members of prey species, just as throughout history many humans have behaved sociopathically to members of other races and tribes - though enslavement has been more common in humans than cannibalism. ["Nothing more strongly arouses our disgust than cannibalism, yet we make the same impression on Buddhists and vegetarians, for we feed on babies, though not our own." - Robert Louis Stevenson.] Either way, the extinction scenario for predatory life-forms needs to be taken seriously - but not out of naïve moralism. The committed abolitionist may tentatively predict that centuries hence lions will not exist outside the digital archives - any more than the smallpox virus. For that matter, one may tentatively predict that the same fate will befall feral Homo sapiens. The conditionally activated capacity to act in bloodthirsty and sexually aggressive ways has been genetically adaptive in the past. We are all the descendants of murderers and rapists. Thus geneticists claim that over 16 million people today may be descended from Genghis Khan. But prediction is not advocacy.

.... One critical response to the prospect of reprogramming carnivorous predators runs as follows. A quasi-domesticated lion that does not prey on members of other species has ceased to be a true lion. Lions, by their very nature, kill members of prey species (and sometimes hyenas, cheetahs and each other). Yes, lions kill their victims in gruesome ways described as "bestial" if done by humans; but such behaviour is perfectly natural if practised by lions: it's one aspect of their "behavioural phenotype". Hunting behaviour is a natural part of their species essence.

Yet here we come to the nub of the issue: the alleged moral force of the term "natural". If any creature, by its very nature, causes terrible suffering, albeit unwittingly, is it morally wrong to change that nature? If a civilised human were to come to believe s/he had been committing acts that caused grievous pain for no good reason, then s/he would stop - and want other moral agents to prevent the recurrence of such behaviour. May we assume that the same would be true of a lion, if the lion were morally and cognitively "uplifted" so as to understand the ramifications of what (s)he was doing? Or a house cat tormenting a mouse? Or indeed a human sociopath? Currently, sociopathy in humans cannot be cured; but various interventions, both genetic and pharmacological, have been mooted.
