James Lovelock (1919-2022): Scientist Who Discovered The 'Goddess'

It was the 1940s. Two young scientists at UK’s National Institute of Medical Research (NIMR) were conducting experiments on heat radiation in order to ‘lessen the painful burns of servicemen exposed to flash or flame.’ The experiments involved measuring ‘the radiant heat flux that would cause burns by using the shaved skin of live rabbits.’

James Lovelock, who hailed from a Quaker family, basically started as a scientist in medical field. He had mostly been an unaffiliated scientist, unattached to any corporate or government body, though he had been a consultant to NASA. He had a home laboratory at Cornwall, UK.

The sailing had not always been smooth.

In the 1950s, he survived a few times by selling his rare blood ‘every few weeks at $50 a pint to keep the family in food.’ To keep his freedom as an ‘independent scientist’, he made some thirty inventions and patented them from time to time. They generated some income to sustain his science and family.

In the 1960s, Lovelock was working as a consultant to NASA in its mission for finding the possibility of life on other planets, particularly in designing instruments to detect signs of life when Viking spacecraft would land on Mars (which it would in 1976). However, Lovelock suggested looking at the dynamics of atmosphere of the planet, rather than going there and fishing for life, as a tell-tale sign of whether or not life as a phenomenon existed on a planet. This was the first seed of Gaia hypothesis in Lovelock.

Later, he would associate himself with the equally rebellious and brilliant microbiologist Lynn Margulis (1938-2011) who was interested in unconventional symbiotic pathways of evolution.

If Lovelock was looking at the entire planet with life shaping it as a planetary phenomenon, Margulis was discovering such connections and pathways at the cellular level. Soon they collaborated. James Lovelock wrote:

But there was also another aspect to this. The problem was not the science but the metaphor Gaia - the pre-Christian Greek Goddess.

Down the decades, the Gaia theory has become an important way of looking at the Earth – it is system-based, scientific, holistic, ecological, artistic and hence on the whole, spiritual. It is a metaphor, Lovelock always emphasised. Science is always filled with metaphors. Like none other in recent times, Gaia has connected the hardcore science of evolution and ecology, geology and hydrology, atmospheric and oceanic science to the collective imagination of humanity.

James Lovelock was also not the usual run-of-the-mill environmentalist. He believed that the nuclear technology, despite the exaggerations of its danger, actually provided the safer and greener energy that we need urgently.

Today, with the climate crisis and the need to understand the Earth systems which we may be tampering with in dangerously irreversible ways, Gaia has emerged as a great framework for science and research.

From a fiercely independent scientist to a visionary challenger as well as a transformer of the way we view planet, life and evolution, James Lovelock represented a pure and indefinable fire that animates science. Even though Gaia does not prove ‘scientifically’ that the Earth ‘lives’ yet it has become a feeling that unites science and earth ethics, art and mysticism.

When he died on 26 July 2022, on his 103rd birthday, the circle was complete.
