That kind of skeptical, questioning, "don't accept what authority tells you" attitude of science — is also nearly identical to the attitude of mind necessary for a functioning democracy. Science and democracy have very consonant values and approaches, and I don't think you can have one without the other.

Talk of the Nation (3 May 1996)

Inner experience, unable to have principles either in dogma (a moral attitude), or in science (knowledge can be neither its goal nor its origin), or in a search of enriching states (an experimental, aesthetic attitude), it cannot have any other concern nor other goal than itself. Opening myself to inner experience, I have placed in it all value and authority. Henceforth I can have no other value, no other authority (in the realm of mind). Value and authority imply the discipline of a method, the existence of a community.
I call experience a voyage to the end of the possible of man. Anyone may choose not to embark on this voyage, but if he does embark on it, this supposes the negation of the authorities, the existing values which limit the possible. By virtue of the fact that it is negation of other values, other authorities, experience, having a positive existence, becomes itself positively value and authority.
Inner experience has always had objectives other than itself in which one invested value and authority. ... If God, knowledge, and suppression of pain were to cease to be in my eyes convincing objectives, ... would inner experience from that moment seem empty to me, henceforth impossible without justification? ...
I received the answer [from Blanchot]: experience itself is authority.

 
Georges Bataille
 

It was once said that democracy is the regime that stands or falls by virtue: a democracy is a regime in which all or most adults are men of virtue, and since virtue seems to require wisdom, a regime in which all or most adults are virtuous and wise, or the society in which all or most adults have developed their reason to a high degree, or the rational society. Democracy, in a word, is meant to be an aristocracy which has broadened into a universal aristocracy. … There exists a whole science—the science which I among thousands of others profess to teach, political science—which so to speak has no other theme than the contrast between the original conception of democracy, or what one may call the ideal of democracy, and democracy as it is. … Liberal education is the ladder by which we try to ascend from mass democracy to democracy as originally meant.

 
Leo Strauss
 

Instead of maintaining the traditional separation of science and values, cognitive theory says the two come together in brain function. If we are correct in saying that our conscious mental values not only arise from, but also influence brain processing, then it becomes possible to integrate values with the physical world on a scientific rather than supernatural basis. It's been the traditional role of religion to affirm the primary importance of our higher values in this world by invoking a supreme power. In cognitivism, it is science that affirms the powerful controlling role of higher values, and it is able to do so on grounds that are verifiable — that is, testable against reality as it really is.
On these new terms, science no longer upholds a value-empty existence, in which everything, including the human mind, is driven entirely by strictly physical forces of the most elemental kind. We get a vastly revised answer to the old question "What does science leave to believe in?" that gives us a different image of science and the kind of truth science stands for. This new outlook leads to realistic, this world values that provide a strong moral basis for environmentalism and population controls and for policies that would protect the long-term evolving quality of the biosphere.

Science is much more than a body of knowledge. It is a way of thinking. This is central to its success. Science invites us to let the facts in, even when they don’t conform to our preconceptions. It counsels us to carry alternative hypotheses in our heads and see which ones best match the facts. It urges on us a fine balance between no-holds-barred openness to new ideas, however heretical, and the most rigorous skeptical scrutiny of everything — new ideas and established wisdom. We need wide appreciation of this kind of thinking. It works. It’s an essential tool for a democracy in an age of change. Our task is not just to train more scientists but also to deepen public understanding of science.

That was my problem then and it's my problem now; I have a bad attitude. In a nutshell, I fear authority but at the same time I resent it -- the authority and my own fear -- so I rebel. And writing SF is a way to rebel. ... SF is a rebellious art form and it needs writers and readers and bad attitudes -- an attitude of "Why?" or "How come?" or "Who says?"
