" it is the human discovery of that molecule that has elevated it to the status of being studied. It was there all along, but now we have imbued it with mystical qualities. Our discovery of it changes nothing about what it does. We often mistake an effect (e.g., of an action, a treatment, a molecule) for our understanding of the effect. What a thing does, and what we think (or know) that it does, are not the same thing. "
