Conservative Christian: If Morality is subjective then there is no real basis for Right and Wrong.
Herald Newman, author of Truth Seeking Atheist blog : Sure there is. Pleasure and pain are a fine basis for morality. We are a social species that depends on other humans for our survival. If I go around and start inflicting unnecessary pain on others, those others are very likely to stop working with me, which means that I’m very likely to not survive. The basis for right and wrong comes from our biology.
Conservative Christian: [If atheists are correct] Morality instead is just based on people’s opinion, and since people’s opinion can often times be arbitrary, that ends up being a problem.
Herald: Is it just your opinion that having your skin burned hurts? Is it just your opinion that getting punched in the face hurts? Is it just your opinion that having a loved one die sucks? These are all subjective experiences that are not at all arbitrary. Morality does not become arbitrary simply because it is subjective.
Conservative Christian: If Morality is subjective, then who decides what is right and wrong?
Herald: We do. We decide what is right and wrong, because our shared evolutionary heritage means that we all share the same kinds of experiences of pleasure and pain. Punching someone in the face is going to inflict pain on that person, and this is not arbitrary, and never will be for the reason that we can make an objective analysis of how harmful our actions are. Once we agree that we want to minimize pain, and maximize pleasure, we can make objective analysis of any action in a given context.
