Quote from "How the Mind Works" by Steven Pinker: "You have channel-surfed to a rerun of L.A. Law, and you want to know why the harpy lawyer Rosalind Shays is weeping on the witness stand. If someone began to explain that the fluid in her tear ducts had increased in volume until the pressure exceeded the surface tension by such and such an amount, you would squelch the lecture. What you want to find out is that she hopes to win a lawsuit against her former employers and is shedding crocodile tears to convince the jury that when the firm fired her she was devastated. But if you saw the next episode and wanted to know why she plummeted to the bottom of an elevator shaft after she accidentally stepped through the open door, her motives would be irrelevant to anyone but a Freudian gone mad. The explanation is that matter in free fall, Rosalind Shays included, accelerates at a rate of 9.8 meters per second."
