objectivism, subjectivism and relativism

1- we have learned that moral norms come from moral behaviors, which contribute to group survival.
these behaviors are enforced by the group by ELDERS. they have the cosmogony of the group. the cosmogony is the narrative of the group.

2- these behaviors are passed on as MEMES. this is what we know as religion (which is the group sets of rituals to ensure survival.

3- moral norms are guarded by the DEITY, in the form of moral COMMANDS (DO NOT DO...)

  
see that the division is whether moral judgments are either dependent (SUBJECTIVIST) or independent (OBJECTIVISTS) of people's beliefs.

moral relativism is the view that moral judgements are relative to people's beliefs or cultural values.

descriptive moral relativism is the view that people do disagree about what is right and wrong, so we owe to tolerate the behavior of others even when we disagree about the morality of it.

here's a sketch:

 1- moral relativism is infallible because it declares moral values a consequence of people's beliefs. your beliefs determine your moral norms. here's an example in real life:

therefore, what makes an action is right is that someone approves of it. 

2- the impossibility of debating moral differences is a result of moral relativism's infallibility.

3- the contradiction of relativism is that an action cannot be both right and wrong at the same time. 

4- actually, moral values are deeper than the relativist make them to be. they are not merely arbitrary, but the result of incremental social behaviors which ensure the survival of the species. these behaviors are passed on to the next generation as social memes.
