So I'm watching Juzo Itami's The Funeral and the way people behave towards the corpse of the deceased got me to thinking that perhaps those of us who are atheists could formulate some new social behaviors and rituals to mesh with our worldview. I'm not saying the old way should be looked down upon or that different cultural and religious practices should not be respected but I thought that perhaps our different beliefs could shift certain ways of doing things.
For starters if we no longer base our rituals upon our heritage than where should we derive them from? Pragmatism perhaps? Cost/benefit analysis... and generally utilitarian? The individual's personal preference prior to death? The family's preference since they are paying for the funeral and the ritual is really for the living? Would cremation be the most pragmatic postmortem procedure? Or something else? Even if we deny the transcendental soul we need not deny individuality. Perhaps the easiest way to honor that individuality is in fact with an intact body.
This is just one possible issue. What about marriage? Eating rituals? Birthing rituals? Circumcision? Bring up some more as you think of them.
