Everyone accepts that there are physical laws. If you jump off a building and try to fly by flapping your arms, gravity will take hold and you will fall. The consequences of violating physical laws are immediate and cannot be disputed. So are there moral laws as well? I say yes. So why do I believe there are moral laws? Because our behaviors have consequences. Not all behaviors lead to equal outcomes. An example would be that men who cheat on their wives are more apt to experience negative consequences than men who are faithful. Some would say, sure, but some men get away with it. That's right they do, but as a rule fidelity leads to harmony and peace while infidelity leads to conflict and chaos. Furthermore, the more they deviate from the standard (i.e. the moral law) the more likely they are to suffer the negative consequences of their decisions. The same thing applies to all behaviors. There will be a standard that if followed will naturally lead to positive outcomes and if deviated from will naturally lead to negative outcomes. As a rule failed behavior lead to failure and successful behaviors lead to success. These are the moral laws. But unlike physical laws, the consequence of violating them are not necessarily immediate.
