Basis for Morality - Natural or Supernatural?

Most of us do not have an active belief in God. It doesn’t mean we don’t go to worship. There are reasons for us not stealing, there are reasons for us not assaulting, and there are reasons for not lying too. These things hurt people. We know that this is not the way to behave. We do not need a God to tell us this. They do not need God in order to learn to live decent lives. They are taught daily certain things you may not do, certain things they must do, and certain things they may do.

The rules of morality were fabricated by human beings over many generations. These rules are: to abstain from injury, to abstain from lying, theft, assault, killing, and so forth. These rules were not the invention of God. No one imagines that if there were not a God to tell us these things, we would not know any better. No one thinks that if God had not told us this, then we would not see anything wrong with my stealing, assaulting, and killing. The Greeks assumed that human morality is based on convention.

You don’t have to be religious to realize that for human beings to live in peace and happiness, they must not assault each other.

I may want to assault, but I do not want to be assaulted.
If I’m tempted to theft, still I do not want to be stolen from.
If I’m tempted to murder, I do not want to be murdered.

The rule thus emerges: Let no one do these things. Then we can live in peace.
