Are individual ants conscious? Somewhat. Are we conscious when we're receiving reality through memes beyond our comprehension? Somewhat.
Are our rods and cones conscious? Our brain stem? The cells that make us vomit? The bacterial colonies in our sinuses?
I just think the answer to all of these questions when all is said and done will be yes. And we'll be sad how much life we killed because we didn't think it was conscious enough.
And maybe if we're lucky when we die we get to watch our consciousness grow to include all things. Maybe that's why we have circuits in our brain that seem to respond that way to mushrooms.
Maybe there's a genetic advantage to harboring the illusion that you are a separate consciousness, but it's just there to make you want to struggle to hold up your tiny corner of a collective consciousness.
