Sure friend.
>conscious being. And that's the trap (of our mind) if a human or any other living creature perceived as a bunch of interconnected particles it becomes obvious that the consciousness is nothing but an ability of such a particles group to react (change its state) to another group of particles.
Whoever said this made a mistake. They assumed they knew something when in fact they knew nothing. If someone were to define consciousness by what it is used for, or what it accomplishes, or what side effects it has, they would be lead quite astray. So when they define consciousness in terms of something it allows, which is reaction to events, they err. Additionally, it seems they made another error when they assumed it is consciousness that allows reaction at all. Rather, the reaction might be a capacity that does not belong to consciousness and they mistakenly attributed it to consciousness, then made the already mentioned error.
Does this at all clarify anything, or would you like more assistance friend?
