Four philosophical questions to make your brain hurt

Interesting article from the BBC. I think it's always good to examine your answers to questions like this, so you can learn more about yourself.

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.

3. IS THAT REALLY 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.

IN CONCLUSION

As TS Eliot once wrote:

"…the end of our exploring,

Will be to arrive where we started,

And know the place for the first time."

Choice Blindness



Often, especially in issues regarding religion or politics. It seems people make choices with conviction and will even kill or die for it. However, is it really a choice out of conviction? What if our choice becomes our conviction, and we essentially "rewrite the past" to fit our choice? Read on for a fascinating experiment on this subject.


The procedure for this experiment was very simple. The experimenter showed willing participants (about half men, half women) pairs of female faces on playing-card-sized photos, one in each hand. Participants pointed to whichever of the two faces they found most attractive. The experimenter then passed the card to the participants and asked them to describe exactly why they found that face attractive.

But wait, this is a psychology experiment, so there's a twist in the tail.

Sometimes, when the experimenter passed the card to participants, there was a little sleight of hand involved. This resulted in the participant staring at the female face they didn't choose.

So, now some people were being asked to justify a decision that, in reality, they hadn't made. Or most of them were - 13% spotted the trick and their data wasn't analysed as their heightened suspicion might have affected their reports.

Before you read the results, have a think about what you might expect. Surely if we were handed the photo with a face we didn't choose, and didn't notice it wasn't the same face, our enthusiasm would at least be dampened.

Perhaps the information would be processed unconsciously leading to a subtle difference in how we report our inner thoughts. For example, we might be more uncertain or more vague about why we preferred this face. After all we didn't prefer this face!

Results

Analysing participants' reports, they couldn't find any difference between the two groups. Both the participants looking at the photo they chose and those looking at the one they didn't both seemed sure of their reasons, used equal specificity, and equal emotionality. It seemed there was no clue in participants' verbal reports of the old switcheroo.

Petter Johansson and colleagues give this phenomena a snappy new name: choice blindness. This, then, is the idea that under certain circumstances we are actually oblivious to the choice we have made.

This 'blindness' was also seen in participants' actual reports of why they preferred one face over the other. Sometimes there was a bleed-through from one face to the other. For example one person said they preferred the woman because she was smiling. In fact it was their original choice, and not the one they were holding who had a slight smile on her face.

Other times participants appeared to have made up the reason why they preferred one over the other. One person said they preferred a woman wearing earrings. In fact only the woman they were shown was wearing earrings, not the original woman they chose.

A little philosophy of science

For a scientist, this experiment leaves a slightly bad taste in the mouth. This is because it relies on drawing a conclusion from an absence; an absence of a difference between the two groups. Scientists frown on this sort of thing because showing that something exists is possible, but showing it doesn't is impossible. Hence, the endless debates over psychic phenomena.

So we have to be cautious about this experiment. Just because there is no difference in the verbal reports between the two groups, a difference could still exist at either an unconscious or even a conscious level.

Nevertheless, I think this experiment does speak to a pervasive human experience. That is, the inability to describe what is attractive about another person. That's probably why we end up using such vague words like 'energy', 'magnetism' or 'electricity'. Perhaps we genuinely don't know.

Great Article on President Elect Obama's Faith



I'm a big believer in tolerance. I think that religion at it's best comes with a big dose of doubt. I'm suspicious of too much certainty in the pursuit of understanding just because I think people are limited in their understanding.

I think that, particularly as somebody who's now in the public realm and is a student of what brings people together and what drives them apart, there's an enormous amount of damage done around the world in the name of religion and certainty.

It's interesting particularly now after this election, comes with it a lot of celebrity. And I always think of politics as having two sides. There's a vanity aspect to politics, and then there's a substantive part of politics. Now you need some sizzle with the steak to be effective, but I think it's easy to get swept up in the vanity side of it, the desire to be liked and recognized and important. It's important for me throughout the day to measure and to take stock and to say, now, am I doing this because I think it's advantageous to me politically, or because I think it's the right thing to do? Am I doing this to get my name in the papers or am I doing this because it's necessary to accomplish my motives.
...
When I'm talking to a group and I'm saying something truthful, I can feel a power that comes out of those statements that is different than when I'm just being glib or clever.

FALSANI:
What's that power? Is it the holy spirit? God?

OBAMA:
Well, I think it's the power of the recognition of God, or the recognition of a larger truth that is being shared between me and an audience.

That's something you learn watching ministers, quite a bit. What they call the Holy Spirit. They want the Holy Spirit to come down before they're preaching, right? Not to try to intellectualize it but what I see is there are moments that happen within a sermon where the minister gets out of his ego and is speaking from a deeper source. And it's powerful.

There are also times when you can see the ego getting in the way. Where the minister is performing and clearly straining for applause or an Amen. And those are distinct moments. I think those former moments are sacred.
...
As I said before, in my own public policy, I'm very suspicious of religious certainty expressing itself in politics.

Now, that's different form a belief that values have to inform our public policy. I think it's perfectly consistent to say that I want my government to be operating for all faiths and all peoples, including atheists and agnostics, while also insisting that there are values tha tinform my politics that are appropriate to talk about.

A standard line in my stump speech during this campaign is that my politics are informed by a belief that we're all connected. That if there's a child on the South Side of Chicago that can't read, that makes a difference in my life even if it's not my own child. If there's a senior citizen in downstate Illinois that's struggling to pay for their medicine and having to chose between medicine and the rent, that makes my life poorer even if it's not my grandparent. And if there's an Arab American family that's being rounded up by John Ashcroft without the benefit of due process, that threatens my civil liberties.

I can give religious expression to that. I am my brother's keeper, I am my sister's keeper, we are all children of God. Or I can express it in secular terms. But the basic premise remains the same. I think sometimes Democrats have made the mistake of shying away from a conversation about values for fear that they sacrifice the important value of tolerance. And I don't think those two things are mutually exclusive.
...
This is something that I'm sure I'd have serious debates with my fellow Christians about. I think that the difficult thing about any religion, including Christianity, is that at some level there is a call to evangelize and prostelytize. There's the belief, certainly in some quarters, that people haven't embraced Jesus Christ as their personal savior that they're going to hell.

FALSANI:
You don't believe that?

OBAMA:
I find it hard to believe that my God would consign four-fifths of the world to hell.

I can't imagine that my God would allow some little Hindu kid in India who never interacts with the Christian faith to somehow burn for all eternity.

That's just not part of my religious makeup.


It is truly wonderful that this man was elected president.
