Certain animals can be conditioned to be called by a certain name. Does that mean that they have a sense of self? It seems like it to me. I don’t know exactly what the limit is, but the main question comes to killing. If the life form is too low to have a sense of self, it should be okay to kill it, right? But then, what about young babies? They don’t have those cognitive abilities at the very beginning of life, do they? No answers for today… I’m tired.
