Here is a classic quotation from John Gummer, for whom I used to work (as a civil servant): “No reasonable person would ignore expert opinion and wager his children’s future on the contrarian views of people who are not peer reviewed.”

This is an appeal to authority – to ‘expert opinion’ which has been ‘peer reviewed’. Now, in straightforward philosophical terms, this argument is an error, it is the epitome of a text-book mistake. Appealing to authority is only as effective as the authority itself which is being cited and conveys no additional weight. In the absence of other consideration it can have some use, certainly it makes for a much more efficient life if the vast majority of our understandings can be developed by those who do things professionally. However, where those authorities themselves are in dispute, where their findings are contentious, then a proper response is not to retreat to ‘authority’ but to engage in the substantial issues.

So, with respect to Global Warming, the emphasis upon ‘consensus’, ‘expert opinion’, ‘peer review’ and all the rest of it makes sense in so far as those things themselves stand up to scrutiny. Where they do not – where, for example, the IPCC is shown to be systematically unscientific and corrupt, where the process of peer review is so problematic, where the predictions made are so at variance with observation – then the argument from authority is not simply mistaken, it is pernicious.

This is not the only field where appeal to authority causes problems, it is simply a very salient issue at the moment given our weather. Having authorities does not absolve us from the responsibility to think for ourselves. Most of all, having authorities does not absolve the church of the responsibility to think for itself on the major issues of the day. I am more and more persuaded that most of the problems with the Church relate to it having given up on the intellect – as if it feels it has lost the battle for intellectual credibility and now tries to justify itself to the world through its acceptance of social progressivism and works of peace and justice. See, we’re nice people, now you don’t need to be so horrible to us by pointing out our intellectual nakedness!

We need to be much more robust. We need to once more believe that theology is the queen of the sciences, and therefore all other knowledge is subordinate to the knowledge of the living God. Doubtless many will instantly cringe at such a cry – that is the depth to which we have fallen. If we concede this, we concede all.
