From a review of Why We Love: The Nature and Chemistry of Romantic Love:
If, as Fisher states, 90 percent of prairie voles stick with one mate for life because they're good dopamine producers and have a sprig of DNA that enhances loyalty, and if norepinephrine automatically floods the brain of a ewe who's on the prowl every time she sees a slide of a ram's face, and those same chemicals burble through the human brain in love, will people one day be able to modify and medicate passions we once regarded as ungovernable? Will not only lust but love be buttressed, cured or even created with a prescription?
The question is not: Can passions be modified by pharamceuticals? The question is: Will we need a prescription for these pharmaceuticals when they become available, and why?
Time to get over our humanist hangover, people. You are the sum of your chemical impulses.
