How so?knot wrote:True, but the ethics on eating oysters seem so flimsy.
In order to eat something, do you assert that we must have a strong argument for the positive ethical value of doing so? Or is it enough that there is no strong argument supporting the negative ethical value of doing so?
If the former, you'd equally rule out any number of nutritionally or environmentally useless food items that are generally considered vegan and harmless.
You'll also have a serious problem with falsifiability. Hidden sins everywhere... we just don't have proof of them? That's not how science works.
With a scientific world view, you go with whatever has the most evidence, and only if the weight of evidence shifts do you change your provisional beliefs.
So the argument goes, although it's unlikely, oysters may be sentient. But since it's easy enough not to eat them we shouldn't. It's easy enough not to eat any particular food item. We could easily avoid cabbage if we arbitrarily wanted to. But why?
We should be able to present a stronger argument than that.
Well, let's have it then.knot wrote:I think it's easy to argue in either direction.

I can make an argument against eating oysters, I'm not sure if it's equally strong to the opposition, but it could be equally or more convincing.
That's not saying much, though, since given my rhetorical skills I could arbitrarily convince most people that it's unethical to wear underwear if they didn't spend too much time looking under the hood of the argument. Anybody skilled at argument can argue anything. Whether the logic is actually there in its most bare form though, is a very different matter.
It depends. Is Veganism an open system of philosophy of minimizing harm caused through diet and lifestyle to other sentient beings, or is it a closed dogma that arbitrarily excludes all animal products and includes all plant products regardless of how environmentally destructive or helpful they are?knot wrote:If someone wants to be vegan by the dictionary definition, he/she can't eat them, though.

While strictly speaking, the vegan society may have the most authority to define the term, it is still a living word and which is NOT a registered trademark, and as such, they don't technically own it (although historical definitions have a lot of weight, common usage and philosophically useful/consistent definitions must also be considered).

Or unethical, for that matter.knot wrote:But that def. does not guarantee something is ethical.
Although slipping by unethical things under the umbrella is of more concern, as is the case with palm oil, which is included in many "vegan" products, but the cultivation of which is one of the most atrocious things happening on Earth today. In terms of climate change, the genocide of orangutans, and destruction of the tropical rain forests on a global scale.

Is veganism based on feelings of personal disgust, or ethics? If ethics, I don't see how it's particularly relevant. And saying these kinds of things is more liable to confuse carnists and make them see veganism as inconsistent dogma rather than do any good.knot wrote:In this case with oyster I think it can be useful to ask why the f' someone would want to eat them to begin with? They are a disgusting food on several levels (they poop, carry viruses, contain heavy metals, etc). Maybe we need some objective standards on what's disgusting!
