Deontological & Teleological Principles

Deontological arguments about the way we should act and how our societies should be governed based on notions of rightness or wrongness. Something can be considered right or wrong through a religious belief or rational argument. So you could say that it's wrong to steal because God says so, or it's wrong to steal because as a rational being we should recognise that we all have the right to property that we earn through our labour. 

A teleological argument would say that it's wrong to steal because if everyone stole everybody else's stuff then it would it would impossible for human beings to function efficiently and fulfill their potential and therefore society could not progress.
