If animals have feelings then isn't that enough reason not to kill them for food? Some would say that self awareness is required. Why would that be relevant? Could the idea that a creature without self awareness lacks a unified state of being over time be a reason? They just sort of exist one moment to the next. Death for them would no different than the passage of time. But then how can mere concepts of self awareness have such an ontological significance? Much of their experience probably or may not be especially pleasurable and many wouldn't exist in the first place if they weren't bred to be eaten. I wonder if the inability of most people to form a moral opinion opposed to animal eating shows something dreadful about the human condition. Here I am sitting and eating meat while asking these questions in the abstract while I've never had the willpower to go vegetarian for any extended period just in case my fears about meat eating are right.
