Ouroboros
Coincidentia oppositorum
You mean fallacy.Well that is because you are using a logical infallacy.
I know what you mean. Yes, the whole universe isn't sentient necessarily because we are, but part of the universe is sentient, because we are. Part of the universe contain matter. Part of it energy. Part of it this and that. All parts, all together, that is what makes the universe, so sentience, as a part, is an integral part of what makes up the universe. Without it, it wouldn't be the whole universe.Helium have electrons that are negatively charged but most helium is neutral.
The universe have humans that are sentient but the universe as a whole is not sentient.
Put it this way, what makes a city? What is New York city, for instance? Is it the buildings? Is it the people? Is it the traffic? Is it the life, motion, experience? We can't remove one or another thing without making a bit less that NY city. Every part is necessary for it to be the whole thing that we're referring to.
So in the same sense, human sentience is a part of the whole, but it's a part it can't be missing, because if we discard it and claim that the whole is something else than what human sentience is, then we're creating a dualism, a segregation of what parts make the whole and what parts do not.
