Scientific fundamentalists claim that science is the disinterested pursuit of truth. But representing science in this way is to disregard the human needs science serves. Among us, science serves two needs: for hope and censorship. Today, only science supports the myth of progress. If people cling to the hope of progress, it is not so much from genuine belief as from fear of what may come if they give it up. The political projects of the twentieth century have failed, or achieved much less than they promised. At the same time, progress in science is a daily experience, confirmed whenever we buy a new electronic gadget, or take a new drug. Science gives us a sense of progress that ethical and political life cannot.
Again, science alone has the power to silence heretics. Today it is the only institution that can claim authority. Like the Church in the past, it has the power to destroy, or marginalise, independent thinkiers. (Think how orthodox medicine reacted to Freud, and orthodox Darwinians to Lovelock.) In fact, science does not yield any fixed picture of things, but by censoring thinkers who stray too far from current orthodoxies it p reserves the comforting illusion of a single established worldview. From the standpoint of anyone who values freedom of thought, this may be unfortunate, but it is undoubtedly the chief source of science’s appeal. For us, science is a refuge from uncertainty, promising — and in some measure delivering — the miracle of freedom from thought; while churches become sanctuaries for doubt.
