We can restate the proposition as: x Even those who are not knowledgeable about a particular field can build an understanding through thought experiments. Perhaps the most interesting use of story is the thought experiment, the intuition pump, that draws on the most instinctive impulses of the human imagination to crack otherwise perplexing philosophical problems. It might go to show that philosophers love a good thought experiment, even if the results arent directly applicable to the real world. In physics and other sciences many famous thought experiments date from the nineteenth and especially the twentieth century, but examples can be found at least as early as Galileo. Philosopher Tyler Burge has argued that the whole experiment is flawed, as Earth Oscar refers to the concept of H2O, while Twin Earth Oscar is referring to the concept of XYZ. Dr. Burge argued that this means their mental states are different from the get-go. Donald Davidson wrote it in 1987: Suppose a man is out for a walk one day when a bolt of lightning disintegrates him.

Ellisons yacht cost $200 million, and if we assume that $400 can repair an obstetric fistula, that means that the suffering relieved by 500,000 obstetric fistula repairs is not greater than the happiness that Ellison gets from his yacht.
