You're not serious?! Since the age of ten or eleven, I've been a secular scientific rationalist. My reason for alluding to the "peaceable kingdom" of Isaiah was to disclaim originality for the vision of a vegan biosphere. Molecular biology provides the tools to turn utopian dreaming into practical policy. — David Pearce
Above I argued:
So you "modestly assume" you have the wisdom and technological ability to genetically alter all life on earth that doesn't meet your ethical standards? — counterpunch
Your answer was an appeal to religious authority.
The prospect of ending the cruelties of Nature isn't a madcap scheme some philosopher just dreamed up in the bathtub. It's a venerable vision: the "peaceable kingdom" of Isaiah. — David Pearce
Your belief that the problem of suffering is morally urgent, is your opinion - and that's all. It's not a fact. It's a subjectively conceived priority. So your allusion to Issiah comes across as an attempt at justification of your opinion, with an appeal to religious authority - which is rather odd for a supposedly secular, scientific rationalist.
If you were a secular scientific rationalist, my argument that science describes an understanding of reality that implies a systematic application of technology - to secure a sustainable future, and thereby relive suffering, should have more impact on you. Maybe you think you're a scientific rationalist, but like West Side Story is really Romeo and Juliet, you are hanging your scientific baubles on the same philosophically religious Christmas tree. And I'm trying to explain to you that applying science for unscientific reasons is why we're headed for extinction.
Admittedly, sustainability is a value - but it's the most objective value conceivable; not least because, one has to exist to have values. The problem of suffering is subjective. You think it important. I don't care about it. I'll concede, unnecessary cruelty to animals is to be avoided, but beyond that I don't care that food animals die. All mortal creatures die, and in the wild suffer far worse than they do on a well run farm - as your Dawkins quote illustrates.
All genetic experimentation is risky; the very nature of sexual reproduction involves gambling with the life of a sentient being. — David Pearce
In your anti-natalist opinion! I disagree; and so we cancel each other out. But you cannot cancel out scientific knowledge. And science as an understanding of reality (it's not just a tool box of neat gadgets to use as you see fit) implies systematic application of technology. On any such list of scientific facts, prioritized in terms of sustainability, risky genetic experimentation is a long way down the list of things we need to do.
One comparatively minor argument for ending animal agriculture is that feeding grain and soya products directly to humans is more energy-efficient than feeding them to factory-farmed nonhuman animals whom humans then butcher. — David Pearce
I'm guessing you've never done a physical days work in your life. A vegetarian diet - with all the necessary supplements, is probably fine for an office worker, or an academic philosopher - i.e. the middle class to whom vegetarianism appeals. But it's simply not adequate to the needs of a manual labourer. Meat is concentrated calories, protein and nutrients - with more energy per kilo than lentil casserole. That's how you can claim vegetarians are more intelligent - and you think that's good science. You're not a scientific rationalist. You're a scientific cherry picker - appealing to your moral opinions and religious authority, as justification for something you refuse to acknowledge is arrogant in the extreme - and precisely mirrors, and justifies the anti-science prejudices of religious conservatives.
Missionaries believed they were morally superior to cannibals. Their moral self-righteousness is not an argument for eating babies. Likewise, the foibles of individual vegans are not a moral argument for harming nonhuman animals. — David Pearce
Scientifically, cannibalism is a bad idea. It's the cause of prion diseases - like CJD, (mad cow disease.) Cannibalism by the natives of Papua New Guinea lead to the spread of a fatal brain disease called kuru that caused a devastating epidemic in the group. There's no need for moral superiority. Simply knowing what's scientifically true and doing what's sustainable is sufficient, and a far more reliable means to reduce suffering.
