These posts are by Jay, Mark, and Mike. I answer them in that order. We have already said this. Breathing is a reflex. There is nothing special about human breathing.
All animals breathe.
Breathing is not an instinct or a behavior anymore than our cells undergoing mitosis and meiosis, the skin covering our bodies, the mobilization of our immune system, or the need for sleep constitute instincts or behaviors. We are talking about social behaviors and relations relative to humans, i.e., capitalism, politics, racism, and so on. You need to come down off this constant sloganeering and endless production of strawmen and non sequiturs if you want people to treat your position with even a remote degree of seriousness. Given everything I have seen so far, I don't see how anybody can treat you seriously at this point. I am a scientific materialist to the bone and believe in biological evolution.
