“Every generation has the illusion that things were easier and better in a simpler past. Dead wrong. Things are better today than at any time in human history. Our primal ignorance is what keeps us whacking each other over the head with sticks, and not what allows us to paint a Mona Lisa or design a space shuttle. The 'primal ignorance that keeps us happy' gives rise to obesity and global warming, not antibiotics or the Magna Carta. If human kind flourishes rather than flounders over the next thousand years, it will be because we fully embraced learning and reason, and not because we surrendered to some fantasy about returning to a world that never really was.”
