I personally would rather live a good life into my prime and be humanely >slaughtered and fed to some higher life form, than never exist at all. For the most part, the >animals I eat would not have ever existed had the demand for meat not existed as well.
It seems to me that when you say 'never exist at all' you are bringing a mystic notion of identity into conscious experience. A lot has been written about personal identity and the like, and I would argue that the notion of one's identity tied to genetic makeup or historical origin is not the most relevant way of approaching the matter. In this way, when you say "I'd prefer to have existed in any case" I ask "point to me who existed". When you reference the life-path of the animal in question I would point out that you are showing me a collection of conscious experiences. What, if any, distinguish these experiences in a fundamental way from other experiences alike but originated in other similar animals? I don't think anything of real relevance.
The idea that somehow whenever you add another animal into the equation you are multiplying the number of entities brought into existence is questionable. It does have moral consequences, however. For instance, if multiplying entities was a real possibility, such that giving birth to animals brought into existence new 'beings', it could be argued that it is preferable to bring two animals to the world, each living 25 years, than bringing only one that lives 50. Assuming that each conscious moment is qualitatively similar in this animals, if you don't believe in the multiplicity of entities, the two scenarios are completely equivalent.
I think that the confusion I point is very prevalent in animal welfare talk, and I think it contaminates rationality for that matter. I have heard people who put a lot of value in the multiplication of entities argue that massive factory farming is desirable precisely for this reason. They reason that, precisely because you are bringing more 'distinct' life into being, even if in deplorable sates, chicken farms are doing something good. If you look at it from a reductionist perspective, you are merely making little brains play again and again the same old plot with slight variations. And the worst is that the plot is actually painful.
You're getting into dangerous philosophical territory here, which is not at all easy to resolve. If there are two animals with very similar brain states are they distinct animals? If not, have we doubled the subjective chance of an animal experiencing the state of the doubled animal? These aren't straightforward questions at all. See the Anthropic Trilemma.
I'm not sure how anyone could argue that bringing more suffering animals into the world is good. I support humane treatment of livestock, which I think makes for a net positive regardless of how the Anth...
I have noticed that among philosophers, vegetarianism of one form or another is quite common. In fact, I became a vegetarian (technically a pescetarian) myself partly out of respect for an undergraduate philosophy professor. I am interested in finding out if there is a similar disproportion in the Less Wrong community.
I didn't request that this go into Yvain's survey because I want more information than just what animal products you do or don't eat; I'd also like to see nuances of the reasons behind your diet. There are a lot more shades than carnivore/vegetarian/vegan - if you want to be a vegetarian but are allergic to soy and gluten, that's a compelling reason to diversify protein sources, for instance. I'd also like to hear about if you avoid any plant foods (if you think they're farmed in a way that's environmentally destructive or that hurts people or if you have warm fuzzy feelings for plants, maybe). Here are some questions that come to mind:
