“I have argued that this sort of thinking is problematic in at least two regards:First, the notion that nonhuman animals do not have an interest in continued existence—that they do not have an interest in their lives—involves relying on a speciesist concept of what sort of self-awareness matters morally. I have argued that every sentient being necessarily has an interest in continued existence—every sentient being values her or his life—and that to say that only those animals (human animals) who have a particular sort of self-awareness have an interest in not being treated as commodities begs the fundamental moral question. Even if, as some maintain, nonhuman animals live in an “eternal present”—and I think that is empirically not the case at the very least for most of the nonhumans we routinely exploit who do have memories of the past and a sense of the future—they have, in each moment, an interest in continuing to exist. To say that this does not count morally is simply speciesist.Second, even if animals do not have an interest in continuing to live and only have interests in not suffering, the notion that, as a practical matter, we will ever be able to accord those interests the morally required weight is simply fantasy. The notion that we property owners are ever going to accord any sort of significant weight to the interests of property in not suffering is simply unrealistic. Is it possible in theory? Yes. Is it possible as a matter of practicality in the real world. Absolutely not. Welfarists often talk about treating “farmed animals” in the way that we treat dogs and cats whom we love and regard as members of our family. Does anyone really think that is practically possible? The fact that we would not think of eating our dogs and cats is some indication that it is not.”

“Animals are property. There are laws that supposedly protect animal interestsin being treated “humanely,” but that term is interpreted in large part to mean that we cannot impose “unnecessary” harm on animals, and that is measured by what treatment is considered as necessary within particular industries, and according to customs of use, to exploit animals. The bottom line is that animals do not have any respect-based rights in the way that humans have, because we do not regard animals as having any moral value. They have only economic value. We value their interests economically, and we ignore their interests when it is economically beneficial for us to do so.At this point in time, it makes no sense to focus on the law, because as long as we regard animals as things, as a moral matter, the laws will necessarily reflect that absence of moral value and continue to do nothing to protect animals. We need to change social and moral thinking about animals before the law is going to do anything more.”

“Veganism is an act of nonviolent defiance. It is our statement that we reject the notion that animals are things and that we regard sentient nonhumans as moral persons with the fundamental moral right not to be treated as the property or resources of humans.”

“When we say that humans have a “right” not to be used for these purposes, this means simply that the interest of humans in not being used as non-consenting subjects in experiments will be protected even if the consequences of using them would be very beneficial for the rest of us. The question, then, is why do we think that it is morally acceptable to use nonhumans in experiments but not to use humans?

“To say that a being who is sentient has no interest in continuing to live is like saying that a being with eyes has no interest in continuing to see. Death—however “humane”—is a harm for humans and nonhumans alike.”

“The notion that we should promote “happy” or “humane” exploitation as “baby steps” ignores that welfare reforms do not result in providing significantly greater protection for animal interests; in fact, most of the time, animal welfare reforms do nothing more than make animal exploitation more economically productive by focusing on practices, such as gestation crates, the electrical stunning of chickens, or veal crates, that are economically inefficient in any event. Welfare reforms make animal exploitation more profitable by eliminating practices that are economically vulnerable. For the most part, those changes would happen anyway and in the absence of animal welfare campaigns precisely because they do rectify inefficiencies in the production process. And welfare reforms make the public more comfortable about animal exploitation. The “happy” meat/animal products movement is clear proof of that. We would never advocate for “humane” or "happy” human slavery, rape, genocide, etc. So, if we believe that animals matter morally and that they have an interest not only in not suffering but in continuing to exist, we should not be putting our time and energy into advocating for “humane” or “happy” animal exploitation.”
