Episode notes
Causal Curiosity Is A Double-Edged Sword
- Human causal curiosity (asking why) enabled science, engineering, and modern medicine.
- The same capacity also produced weapons and large-scale harms, making intelligence a double-edged sword.
Animals Deceive; Humans Lie To Beliefs
- Deception exists widely in nature, from Venus flytraps to cuttlefish camouflage.
- Humans uniquely deploy deception as lying by manipulating others' beliefs via theory of mind.
Humans Alone Grasp Personal Mortality
- Many animals hold a minimal concept of death (living vs dead).
- Only humans so far appear to grasp personal inevitable mortality, which fuels culture and existential suffering.
