I was using sentience as a synonym for self-awareness.
If you wish to argue that dogs are sentient but not self-aware, go ahead. But the whole reason I'm saying you guys shouldn't be saying this guy should be executed is because dogs are not self-aware.
This is the first logical argument you've made.
Unfortunately, it isn't appropriate for this specific situation (where a guy kills two dogs and posts pictures on facebook):
There are already laws that protect animals from being killed that rely on other forms of "value". Endangered animals are protected because without them, vital parts of the food chain would be missing, or we would be without a beautiful species to put in our zoos forever. I fully support severe prosecution for poachers who kill endangered species.
The intellect of humans is directly related to how we live our lives. If you get killed at age 15, you are going to miss out on a lot in life. The reason every single legal system in the world frowns upon murder is because humans choose to mutually agree on not killing eachother so that everyone is relatively safe from being murdered. Dogs do not share these same kinds of experiences.
which is the whole point of the mirror test...
It's appropriate in relation to the argument debating human superiority. I disagree that this was the first logical argument I was able to produce, considering it was one of the primary arguments I had argued in the past (though you may have accidentally dodged it).
Now, aside from my previous argument considering all aspects promoted by individual species, the way in which you present value is based on how an individual is aware of their value. The problem with this is that, regardless of self awareness, immorally speaking, once a creature has been killed, offering absolutely nothing that would severely downgrade the species, their potential value has literally become nothing, and is no longer of value aside from those who care and are aware of it, right?
