Colin A. Chapman and Michael A. Huffman, Why do we want to think humans are different?
Chapman & Huffman’s moral analysis fails to prove that the exploitation of animals or the environment is causally connected to beliefs about human capacities. Their exposition of the philosophical interpretations of animal cognition ignores historical context and confounds different levels of analysis. Their analysis of the scientific literature, from which they conclude that humans should not be considered as different from other animals, does not take into account many recent psychological and neuroscientific developments and rests upon a flawed understanding of the relationship between gradual and categorical differences, misrepresenting the two as mutually exclusive concepts.
