Brian Key, Why fish do not feel pain


Key’s (2016) target article, “Why fish do not feel pain,” is based on a moralistic fallacy where conclusions about natural conditions are drawn not from research and experiments, but from subjective moral views on how things should be. Moreover, the neurobiological findings purporting to show that fish do not feel pain are insufficient for drawing this conclusion.
