Do you know what we call opinion in the absence of evidence? We call it prejudice.
That is the danger we now face. And this is why the intermixing of science and politics is a bad combination, with a bad history. We must remember the history, and be certain that what we present to the world as knowledge is disinterested and honest.
The past history of human belief is a cautionary tale. We have killed thousands of our fellow human beings because we believed they had signed a contract with the devil, and had become witches. We still kill more than a thousand people each year for witchcraft. In my view, there is only one hope for humankind to emerge from what Carl Sagan called "the demon-haunted world" of our past. That hope is science.

Scientific research was much like prospecting: you went out and you hunted, armed with your maps and instruments, but in the ened your preparations did not matter, or even your intuition. You needed your luck, and whatever benefits accrued to the diligent, through sheer, grinding hard work.
In science, the old men are usually wrong. But in politics, the old men are wise, counsel caution, and in the end are often right.
