I have an article about antinatalism, although when I wrote it, the concept of "antinatalism" was not familiar to me (I wrote article in 2004, but I think it is still highly topical). I offered article to philosophical journal, but they decided not to publish it.

About decade ago I published it at some philosophy forums. After that, I had made to my article some recent changes.

Can I publish it here?

I'm not a moderator, but I don't see why not. I'd be interested.

The headache itself is part of your self-experience, or, put simpler, just part of yourself

The aching of your head is the aching of your inner mental magical world. Not of yourself. A pain in the ass would be pain of yourself, yourself being your body. You experience pain inside as you experience vision as being in the outer world, or phantom pain in the ass (would be rather rare though...). Doesnt take away the fact that pains no nice. Head ache is a way for the inner world to tell you something. That it has thought enough for example.
