Untethered
Unraveling human nature through instinct, culture, and reason
I wrote it for the moment you realize your worldview was assembled for you — and you want to build one deliberately instead.
Untethered traces how instinct, culture, and reason shape the human mind — then asks what it means to take responsibility for the models you live inside. It moves through the layers of knowledge: inborn (instinct, evolution) → learned (culture, belief, language) → chosen (reason, first principles).
Use it to notice what you inherited, name what you actually believe, and choose what you stand on.
