Punching My Constructed People

Ought I to punch, in the face, someone in my perceived reality?

Umm... No; probably not. Firstly, I think it is important to remember that lack of evidence for reality being external does not mean that reality isn't external. In this same way, lack of evidence for reality being internal does not mean that reality is not, in fact, internal. I think depending which view we take, we need to recognize that maybe we are horribly wrong. In fact, before we make that choice we may want to consider to possible consequences of being right or wrong about either view.

If you agree that reality is external, punching someone in the face may very well land you in a prison that is real and external to you. So, this view would mean that you wouldn't want to punch someone in the face unless you particularly wanted to risk going to prison.

If you agree that reality is internal, the result of punching someone in the face will depend on how well you can force your mind to believe something and impose it upon your reality. If you punch someone in the face chances are that your mind, in my mind's experience, will not have the strength to keep you out of prison; the people whom you construct will throw you in a prison that you constructed/conceived of on your own. Of course, there isn't really any way of knowing if you'll succeed, unless you have experienced failure in doing so before this point in "time."

My advice: don't punch people in the face.
