If one believes it's a Godless universe (as I do because that has to be the common sense view based on evidence), then I also believe that human beings act within various tolerance levels of self-respect, levels that accrete gradually from babyhood via nurture rather than nature.
Nature or Nurture above? The only question: is there ANY nature involved?
Common sense seems to indicate a varying susceptibility, by nature, to
nurture and nature. But none of this NEED connote a religion, Christian or
otherwise. Common sense SEEMS to indicate that there can be no religion
possible which is truly a religion (i.e. true)! The above 'accretion of
tolerance levels' is just an instinctive process, not a supernatural one.
Human life, it seems, depends on a self-respect that is cherry-picked from
nurture and/or nature.
This happens gradually (accretion).
Religion needs to be false to be a religion (faith), otherwise, if it's
true, it ceases to be a religion at all because you no longer need faith to
believe it. Religion is, by common sense, a side-issue, but religion is
often imported into nurture by nurturers and in that way becomes a
main-issue.
