We white Anglo-Saxon Protestants, British, German, American, have been on a rampage, for the past hundred or more years, to improve the world
To improve the world
We have given the benefits of our culture, our religion, our technology to everybody
Except perhaps the Australian aborigines
And we have insisted that they receive the benefits of our culture, even our political styles, our democracy
You better be Democratic, or we'll shoot you
And having conferred these blessings all over the place, we wonder why everybody hates us
See, because sometimes, doing good to others, and even doing good to oneself
Is amazingly destructive, because it's full of conceit

[Chorus]
How do you know what's good for other people?
How do you know what's good for you?
If you say you want to improve, you ought to know what's good for you
But obviously, you don't, because if you did, you would be improved
How do you know what's good for other people?
How do you know what's good for you?
If you say you want to improve, you ought to know what's good for you
But obviously, you don't, because if you did, you would be improved

So we don't know
It's like the problem of geneticists, which they face today
I went to a meeting of geneticists not so long ago, where they gathered in a group of philosophers and theologians and said, "Now, look here. We need help."
We now are on the verge of figuring out how to breed any kind of human character
We would want to have
We can give you saints, philosophers, scientists, great politicians, anything you want
Just tell us, what kind of human beings ought we to breed?
So, I said, "How will those of us who are genetically unregenerate make up our minds what genetically generate people might be?”
Because I'm afraid, very much, that our selection of virtues may not work
It may be like, for example, this new kind of high-yield grain
Which is becoming ecologically destructive
When we interfere with the processes of nature and breed efficient plants and efficient animals
There's always some way in which we have to pay for it
And I can well see that eugenically-produced human beings might be dreadful
We could have a plague of virtuous people
You realize that?
You realize that?
Any animal considered in itself is virtuous, it does its thing, but in crowds, they're awful
Like a crowd of ants or locusts on the rampage
They're all perfectly good animals, but it's just too much
I could imagine a perfectly pestiferous mass of a million saints
[Chorus]
How do you know what's good for other people?
How do you know what's good for you?
If you say you want to improve, you ought to know what's good for you
But obviously, you don't, because if you did, you would be improved
How do you know what's good for other people?
How do you know what's good for you?
If you say you want to improve, you ought to know what's good for you
But obviously, you don't, because if you did, you would be improved

So I said to these people, "Look, the only thing you can do, just be sure that a vast variety of human beings is maintained."
Don't, please, breed us down to a few excellent types
Excellent for what?
Excellent for what?
We never know how circumstances are going to change, and how our need for different kinds of people changes
At one time, we may need very individualistic and aggressive people
At another time, we may need very cooperative team-working people
At another time, we may need people who are full of interest in dexterous manipulation of the external world
At another time, we may need people who explore into their own psychology and are introspective
There is no knowing
But the more varieties and the more skills we have, obviously, the better
So, you see, here again, the problem comes out in genetics
We do not really know how to interfere with the way the world is
