Construct an ethical/philosophical argument supporting a non-human species
Reread my somewhat whimsical reflections on my dog Rusty and his memory capacity or on bugs and their sense of ongoing pain (or not). Presumably, it is largely Rusty’s capacity, however limited, to have memories that would make us nervous about using him for medical experiments (or prematurely ending his life, so he could become, say, a meal for us). Whereas we would have very little qualms about stomping on the cockroach, because Mr. Cockroach’s sentience doesn’t exist in-time very much at all (it does not anticipate; it does not regret). Construct an ethical/philosophical argument supporting a non-human species “right” to survive (or not), by focusing on a thresh-hold mental-capacity example somewhere between a dog and a cockroach (a cow? a bird? a lizard?).
