If we take the position that an assessment that veganism is morally preferable to vegetarianism is not possible because we are all "on our own journey," then moral assessment becomes completely impossible or is speciesist. It is impossible because if we are all "on our own journey," then there is nothing to say to the racist, sexist, anti-semite, homophobe, etc. If we say that those forms of discrimination are morally bad, but, with respect to animals, we are all "on our own journey" and we cannot make moral assessments about, for instance, dairy consumption, then we are simply being speciesist and not applying the same moral analysis to nonhumans that we apply to the human context.

In an earlier stage of our development most human groups held to a tribal ethic. Members of the tribe were protected, but people of other tribes could be robbed or killed as one pleased. Gradually the circle of protection expanded, but as recently as 150 years ago we did not include blacks. So African human beings could be captured, shipped to America, and sold. In Australia white settlers regarded Aborigines as a pest and hunted them down, much as kangaroos are hunted down today. Just as we have progressed beyond the blatantly racist ethic of the era of slavery and colonialism, so we must now progress beyond the speciesist ethic of the era of factory farming, of the use of animals as mere research tools, of whaling, seal hunting, kangaroo slaughter, and the destruction of wilderness. We must take the final step in expanding the circle of ethics. -
