Root Goal - How to Define it
To define the root goal is tricky, but I generally say the root goal is to transmit your genes to future generations.
Tricky points about the definition of the root goal:
Survival, but not individual survival. Species survival.
How to define a species? A species adapts through time.
Gene transmission - not just to the next generation, but to every future generation. Open-ended survival.
Genes, but which genes?
Pleasure, usually coupled to gene transmission, but sometimes hijacked artificially.
Since the root goal is open-ended, it's an infinite regression and therefore can't really provide a "meaning of life."
