We missed World Philosophy Day last Thursday, but we can still celebrate it today.  The BBC magazine gives us four philosophical questions to consider.  Feel free to comment with your own answers. 

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?

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?

[Y]ou cannot independently check your senses. You cannot jump outside of the experiences they provide to check they’re generally reliable. So your senses give you no reason at all to believe that there is a computer screen in front of you.”

4. DID YOU REALLY CHOOSE TO READ THIS ARTICLE?

Suppose that Fred existed shortly after the Big Bang. He had unlimited intelligence and memory, and knew all the scientific laws governing the universe and all the properties of every particle that then existed. Thus equipped, billions of years ago, he could have worked out that, eventually, planet Earth would come to exist, that you would too, and that right now you would be reading this article.
