In an earlier post, I wrote that the purpose of life is moral progress. If the word purpose produces a negative reaction for you, it would be equally true to say that evolution has given human life an upward moral direction because the moral intuition we refer to as conscience is aligned with the survival of our species, IMO.It is, in my opinion, a very false notion that my life entails a "purpose" that is not entirely my own. It assumes that my life somehow devolves from something else, and that this "purpose" of my life is not mine, but belongs to that something else....
For example, the bullying aggression of people like Adolf Hitler is a threat to our survival. Conscience (moral intuition) justifies killing people like that in self-defense but signals us with a feeling of wrongness when innocent people are killed.
