Laura Bynum quotes:

We knew the difference between that which cannot be expressed and that which must. We understood that while words are a path taking us only so far, they are a requisite to the journey. They are like road maps that show us which way to go.

In a world where critical thinking skills are almost wholly absent, repetition effectively leapfrogs the cognitive portion of the brain. It helps something get processed as truth. We used to call it unsubstantiated buy-in. Belief without evidence. It only works in a society where thinking for one's self is discouraged. That's how we lost our country.
