Quantification, experimentation, rigor, repetition, prediction - all of these are part of the experimental sciences. There's an iconography also namely man, and I do mean males in white coats who spin dials and wait for numbers to appear.

In my mind the job of a natural scientist is to bend over backwards to say something which can be demonstrated to be true or at least which is not of such a nature that there's no way to demonstrate that it's false.

An ecosystem, you can always intervene and change something in it, but there's no way of knowing what all the downstream effects will be or how it might affect the environment. We have such a miserably poor understanding of how the organism develops from its DNA that I would be surprised if we don't get one rude shock after another.

The general public doesn't know and probably doesn't care about punctuated equilibria nor indeed should they, or the greenhouse effect on some other planet - they barely have the ability to cope with the greenhouse effect on their own planet. So I think you have to distinguish between the broad visibility of a scientist when he or she is speaking to a general public and trying to address general issues and the continued position that a scientist may have into the history of a particular subject.

We take the side of science in spite of the patent absurdity of some of its constructs, in spite of its failure to fulfill many of its extravagant promises of health and life, in spite of the tolerance of the scientific community for unsubstantiated just-so stories, because we have a prior commitment, a commitment to materialism... We cannot allow a Divine Foot in the door.

The vulgarization of Darwinism that sees the "struggle for existence" as nothing but the competition for some environmental resource in short supply ignores the large body of evidence about the actual complexity of the relationship between organisms and their resources.

I assume the same problem exists in Australia as in America of back-biting and jealousy and parochialism among disciplines - there are the scientists, and there are the humanities people, and there are chemists and the physicists and everybody snipes at everybody else and inter-disciplinary communication is rare. But it's very precious and necessary.
