There is a man named Bob, who buys a Bugatti. One day he is at the railway and in the distance he sees a little girl on the train tracks. He has a decision to make; he should flip the switch so that the train misses the little girl and hits his truck, or he should allow the train to kill the girl, but his investment is safe because the Bugatti is safe. The premises are one, Bob buys a non-essential object, a Bugatti. Two: the little girl will not die, as long as the train hits Bob's Bugatti and not the little girl. Three, Bob's behavior will be morally unacceptable if he does not flip the switch (Singer 225-226). Singer includes other analogies that follow his main premise and his conclusion is always the same, it is immoral to buy something non-essential
