We often deploy the clumsy ideas of nature and nurture to describe what is innate in us, and what is extrinsic. What this really means is: genetics (that is, what is encoded in DNA), and everything else in the universe. Your genome is a script, etched into the kernel at the center of your cells, but the film of your life is played out in the countless forces that determine how that script is performed. Nature was never versus nurture; it is and always was via.
