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.

We proclaim human intelligence to be morally valuable per se because we are human. If we were birds, we would proclaim the ability to fly as morally valuable per se. If we were fish, we would proclaim the ability to live underwater as morally valuable per se. But apart from our obviously self-interested proclamations, there is nothing morally valuable per se about human intelligence.

The distinction between meat and other animal products is total nonsense. Vegetarianism is a morally incoherent position. If you regard animals as members of the moral community, you really don’t have a choice but to go vegan.

Domesticated animals such as dogs and cats are vulnerable and entirely dependent on us for all of their needs. They live very unnatural lives because they are not part of the human world and they are not part of the animal world.

I certainly believe that we have a moral obligation to care for the dogs, cats, and other nonhumans whose existence we have caused or facilitated as part of the institution of 'pet' ownership. But I maintain that we ought to abolish the institution and stop causing or facilitating the existence of more 'companion' animals.

Not only are the philosophies of animal rights and animal welfare separated by irreconcilable differences... the enactment of animal welfare measures actually impedes the achievement of animal rights... Welfare reforms, by their very nature, can only serve to retard the pace at which animal rights goals are achieved.

Any serious social, political, and economic change must include veganism.
