In his reply to the Nobis-Graham review of Tibor Machan's book, Putting Humans First, John Altick defends Machan's and Rand's theories of moral rights, specifically as they relate to the rights of non-human animals and non-rational human beings. Nobis and Graham argue that Altick's defense fails and that it would be wrong to eat, wear, and experiment on non-rational—yet conscious and sentient—human beings. Since morally relevant differences between these kinds of humans and animals have not been identified to justify a (...) difference in treatment or consideration, it is wrong to harm animals for these purposes also.
