Richard Hamming

« All quotes from this author

Most people like to believe something is or is not true. Great scientists tolerate ambiguity very well. They believe the theory enough to go ahead; they doubt it enough to notice the errors and faults so they can step forward and create the new replacement theory. If you believe too much you'll never notice the flaws; if you doubt too much you won't get started. It requires a lovely balance.

So to the book's provocation, the statement that nearly half the people in the United States don't believe in evolution. Not just any people but powerful people, people who should know better, people with too much influence over educational policy. We are not talking about Darwin's particular theory of natural selection. It is still (just) possible for a biologist to doubt its importance, and a few claim to. No, we are here talking about the fact of evolution itself, a fact that is proved utterly beyond reasonable doubt. To claim equal time for creation science in biology classes is about as sensible as to claim equal time for the flat-earth theory in astronomy classes. Or, as someone has pointed out, you might as well claim equal time in sex education classes for the stork theory. It is absolutely safe to say that if you meet somebody who claims not to believe in evolution, that person is ignorant, stupid or insane (or wicked, but I'd rather not consider that).

Richard Dawkins

There is one feature I notice that is generally missing in "cargo cult science." It's a kind of scientific integrity, a principle of scientific thought that corresponds to a kind of utter honesty ó a kind of leaning over backwards. For example, if you're doing an experiment, you should report everything that you think might make it invalid ó not only what you think is right about it; other causes that could possibly explain your results; and things you thought of that you've eliminated by some other experiment, and how they worked ó to make sure the other fellow can tell they have been eliminated.
Details that could throw doubt on your interpretation must be given, if you know them. You must do the best you can ó if you know anything at all wrong, or possibly wrong ó to explain it. If you make a theory, for example, and advertise it, or put it out, then you must also put down all the facts that disagree with it, as well as those that agree with it. There is also a more subtle problem. When you have put a lot of ideas together to make an elaborate theory, you want to make sure, when explaining what it fits, that those things it fits are not just the things that gave you the idea for the theory; but that the finished theory makes something else come out right, in addition.
In summary, the idea is to try to give all of the information to help others to judge the value of your contribution; not just the information that leads to judgment in one particular direction or another.

Richard Feynman

Today the theory of evolution is about as much open to doubt as the theory that the earth goes round the sun.

Richard Dawkins

I also donít think that there is really a theory of intelligent design at the present time to propose as a comparable alternative to the Darwinian theory, which is, whatever errors it might contain, a fully worked out scheme. There is no intelligent design theory thatís comparable. Working out a positive theory is the job of the scientific people that we have affiliated with the movement. Some of them are quite convinced that itís doable, but thatís for them to proveÖNo product is ready for competition in the educational world.

Phillip E. Johnson

The range of what we think and do is limited by what we fail to notice. And because we fail to notice there is little we can do to change until we notice how failing to notice shapes our thoughts and deeds.
