"Four philosophical questions to make your brain hurt"

[Daz]

They aren't that bad, but good for a musing never the less. Snippets:

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. YOU ARE NOT THE 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.

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.

4. YOU DID NOT FREELY AND RESPONSIBLY 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.

Go, ponder!
