Trying to define personhood using any sort of scientific analysis is a dangerous road that was&#x2F;is used to justify horrific acts of racism, violence, and subjugation, including Social Darwinism in the early 1900s, and the eugenics movement that followed.<p>I can think of no objective testable definition of person which is both meaningful (i.e. non-trivial) and not horrific for corner cases or those that would be excluded.<p>I know this wasn&#x27;t your intention because you&#x27;re using it to grant personhood to more entities but the implications aren&#x27;t great regardless.
