Det finnes lite som er mer givende enn å la hjernen leke med intrikate filosofiske spørsmål. Slik filosofering gjør at man kan se på verden og seg selv fra en helt annen vinkel enn den man vanligvis er fastlåst i.
Her er fire filosofiske spørsmål du kan leke deg med:

1. SHOULD WE KILL HEALTHY PEOPLE FOR THEIR ORGANS?
Suppose Bill is a healthy man without family or loved ones. Would it be ok painlessly to kill him if his organs would save five people, one of whom needs a heart, another a kidney, and so on? If not, why not?
2. ARE YOU THE SAME PERSON WHO STARTED READING THIS ARTICLE?
Consider a photo of someone you think is you eight years ago. What makes that person you? You might say he she was composed of the same cells as you now. But most of your cells are replaced every seven years. You might instead say you’re an organism, a particular human being, and that organisms can survive cell replacement – this oak being the same tree as the sapling I planted last year.
But are you really an entire human being? If surgeons swapped George Bush’s brain for yours, surely the Bush look-alike, recovering from the operation in the White House, would be you. Hence it is tempting to say that you are a human brain, not a human being.
3. IS THAT REALLY A COMPUTER SCREEN IN FRONT OF YOU?
What reason do you have to believe there’s a computer screen in front of you? Presumably that you see it, or seem to. But our senses occasionally mislead us. A straight stick half-submerged in water sometimes look bent; two equally long lines sometimes look different lengths.
