There seems to be a popular form of virtual atheism where the person says: I don't believe in god, but I don't accept that 'everything is permitted.' And then they grin in an idiotic way.
If 'everything is permitted' means exactly the same thing as there are no laws but man made laws, what can they mean? All laws are arbitrary unless they where given by some power from above, or if the very universe is 'good.' What else can they mean?
If it is some kind of conditioned response or Freudian figure (which leads to the belief in goodness and guilt), that is ultimately based on meaningless phylogenetic antecedents.
So if someone says that don't they just mean they don't like to admit morals are meaningless or radically arbitrary? Perhaps because they are confused.
