IN 1633 Galileo Galilei was hauled before the religious authorities of his day, the Inquisition, for daring to concur with Copernicus that the Earth was not the centre of the universe and also that it orbited the sun rather than the other way around. For his pains, he was placed under house arrest and forced to recant. Giordano Bruno failed to recant and suffered a crueller fate.

Today we are faced with a newer religion known as environmental activism which has insinuated itself into some aspects of science. It shares some of the intolerance to new or challenging ideas with the old. Immolation at the stake is no longer fashionable but it has been replaced by pillory in the media.

The new faith makes it apostasy to question the proposition that our river systems are dying and that nothing like this has ever happened before. And it is the blackest heresy to suggest that the beatification of StAl and the Goronites may be a little premature.

The symbols and practices of the new and the old faiths are remarkably similar.

The crucifix has been replaced by the wind turbine; where before there was the hair shirt and self-flagellation, mortification of the flesh now consists of switching off your airconditioner when it’s hot and your patio heater when it’s cold.

The head of the University of Tasmania’s school of government, Aynsley Kellow, has pointed out the close similarity between medieval papal indulgences and carbon offsets. However, these things matter less than the corruption of science by faith and the failure to recognise the contingent nature of scientific concepts. Concepts are only valid until such time as they are demolished by the scientific methods of observation, measurement, experimentation and analysis.

Phrases such as “the argument is over, the science is settled” are so much fatuous nonsense and should almost never be used in the scientific community.

Throughout history dissenters, sceptics, contrarians and innovators have suffered criticism, abuse and even persecution, but it is these people who have driven progress.

To quote Thomas Huxley, “scepticism is the highest of duties, blind faith the one unpardonable sin”.

Where would we be without the Galileos, Newtons, Darwins and Pasteurs? I would like to think that some time in the future we could add the names of our scholars to that list.
