- The Ascent of Man (1972) - an account of how humanity has evolved culturally and technology via biological and man-made tools. Presented by mathematician and renaissance man Jacob Bronowski.
- Cosmos (1980) - the history of astronomy and planetary exploration, interwoven with the origins of life. Presented by Carl Sagan (as if you didn't know).
- The Day the Universe Changed (1985) - a study of how scientific and technological breakthroughs in Western society generate paradigm shifts. Presented by the historian of science James Burke.
All three series have been proclaimed 'landmark' shows so it is interesting to compare their themes, viewpoints and production techniques, discovering just how similar they are in many ways. For a start, their excellent production values allowed for a wide range of international locations and historical recreations. They each have a charismatic presenter who admits to espousing a personal viewpoint, although it's quite easy to note that they get progressively more casual: if Jacob Bronowski has the appearance of a warm elder statesman then Carl Sagan is the father figure for a subsequent generation of scientists; James Burke's on-screen persona is more akin to the cheeky uncle, with a regular supply of puns, some good, some less so.
To some extent it is easy to see that the earliest series begat the second that in turn influenced the third. In fact, there is a direct link in that Carl Sagan hired several of the producers from The Ascent of Man for his own series, clearly seeing the earlier show as a template for Cosmos. What all three have is something extremely rare in other science documentaries: a passion for the arts that promotes a holistic interpretation of humanity's development; science does not exist in isolation. As such, the programmes are supported by superbly-illustrated tie-in books that extend the broadcast material from the latter two series whilst Bronowski's book is primarily a transcript of his semi-improvised monologue.
In addition to considering some of the standard examples of key developments in Western civilisation such as Ancient Greece and Galileo, the series include the occasional examination of Eastern cultures. The programmes also contain discussions of religions, both West and East. In fact, between them the series cover a vast amount of what has made the world the way it is. So not small potatoes, then!
The series themselves:
The Ascent of Man
To some extent, Jacob Bronowski was inspired by the earlier series Civilisation, which examined the history of Western arts. Both series were commissioned by David Attenborough, himself a natural sciences graduate who went on to present ground-breaking series in his own discipline as well as commissioning these landmark programmes. (As an aside, if there are any presenters around today who appears to embody the antithesis of C.P. Snow's 'the two cultures' then Sir David is surely in the top ten).Bronowski's presentation is an astonishingly erudite (for all its improvisation) analysis of the development of our species and its technological society. Although primarily focused on the West, there is some consideration of other regions, from the advanced steel-making technology of medieval Japan to Meso-American astronomy or the relatively static culture of Easter Island. Time and again, the narrative predates the encumbrance of political correctness: that it was the West that almost solely generated our modern technological society - the 'rage for knowledge' for once outshining dogma and inertia.
Of course, it would be interesting to see how Bronowski might have written it today, in light of Jared Diamond's ground-breaking (in my humble opinion) Guns, Germs and Steel. Although he works hard to present science, the plastic arts, literature and myth as emerging from the same basic elements of our nature, it is clear that Bronowski considers the former to be much rarer - and therefore the more precious - discipline. Having said that, Bronowski makes a large number of Biblical references, primarily from the Old Testament. In light of the current issues with fundamentalism in the USA and elsewhere, it is doubtful that any science documentary today would so easily incorporate the breadth of religious allusions.
If there is a thesis underlying the series it is that considering how natural selection has provided humanity with a unique combination of mental gifts, we should use them to exploit the opportunities thus presented. By having foresight and imagination, our species is the only one capable of great heights - and, as he makes no pretence of - terrible depths. As he considers the latter, Bronowski admits that we should remain humble as to the state of contemporary knowledge and technology, which five hundred years hence will no doubt appear childlike. In addition, he states that belief in absolute knowledge can lead to arrogance; if we aspire to be gods, it can only end in the likes of Auschwitz. But his final speeches contain the wonderful notion that the path to annihilation can be avoided if science is communicated to all of society with the same vigour and zest as given to the humanities.
Cosmos
I was already an astronomy and astronautics fan when I saw this series. Its first UK broadcast slot was somewhat later than my usual bedtime, so it seemed a treat to be allowed to stay up after the rest of the family had gone to bed. Like Star Wars a few years before, it appeared to me to be an audio-visual tour-de-force; not surprisingly, both the tie-in hardback and soundtrack album arrived on my birthday that year.Nostalgia aside, another key reason for the series' success was the charisma of the presenter himself. Much has been written of Sagan's abilities as a self-publicist, and the programmes do suffer from rather too many staring-beatifically-into-the-distance shots (as to some extent replicated more recently by Brian Cox in his various Wonders Of... series). Of course, it must have taken considerable effort to get the series made in the first place, especially in gaining a budget of over $6 million. After all, another great science populariser, the evolutionary biologist Stephen Jay Gould, never managed to gain anything beyond the occasional one-off documentary.
What is most apparent is Sagan's deep commitment to presenting science to the widest possible audience without distorting the material through over-simplification. However, in retrospect it is also obvious that he was using ideas from several scientific disciplines, such as the Miller-Urey experiment, to bolster his opinions on the likelihood of extra-terrestrial life. To some extent his co-writers reined him in, the final episode given over not to SETI but to plea for environmental stewardship.
Whilst the series is primarily concerned with a global history of astronomy and astrophysics, supplemented with first-hand accounts of planetary exploration, Sagan like Bronowski is equally at home with other scientific disciplines. He discusses the evolution of intelligence and incorporates elements of the humanities with equal aplomb. Another key element is the discussion of the role superstition and dead ends have played in the hindrance or even advancement of scientific progress, from Pythagorean mysticism, via Kepler's conflation of planetary orbits with the five Platonic solids, to Percival Lowell's imaginary Martian canals. Although Sagan repeats his earlier debunking of astrology, UFO sightings and the like, he doesn't rule out the role of emotions in the advancement of science and technology, citing for example the rocket pioneer Robert Goddard's Mars-centred epiphany.
Perhaps the primary reason that the series - despite the obvious dating of some of the knowledge - is still so engaging and why Sagan's narration is so widely quoted, is that he was a prose poet par excellence. Even when discussing purely scientific issues, his tone was such that the information could be effortlessly absorbed whilst allowing the viewer to retain a sense of wonder. Of course, Sagan had ample assistance from his two co-writers Ann Druyan and Steven Soter, as clearly proven by their scripts for the Neil deGrasse Tyson-hosted remake Cosmos: A Spacetime Odyssey. Nonetheless, it is hard to think of another presenter who could have made the original series the success it was on so many levels.
The Day the Universe Changed
Although James Burke had already made a large-scale history of science and technology series called Connections in 1978, it contained a rather different take on some of the same material. By focussing on interactive webs, the earlier series was somewhat glib, in that some of the connections could probably be replaced by equally valid alternatives.In contrast, The Day the Universe Changed uses a more conventional approach that clearly shares some of the same perspectives as the earlier programmes. Like The Ascent of Man and the Cosmos remake, mediaeval Islamic science is praised for its inquisitiveness as well as the preservation of Classical knowledge. Burke was clearly influenced by his predecessors, even subtitling the series 'A Personal View by James Burke'. Perhaps inevitably he covers some of the same material too, although it would be difficult to create a brief history without reference to Newton or Ancient Greece.
As with Bronowski, Burke integrates scientific advances within wider society, a notable example being the rediscovery of perspective and its profound effect on contemporary art. He also supports the notion that rather than a gradual series of changes, paradigm shifts are fundamental to major scientific breakthroughs. In effect, he claims that new versions of the truth - as understood by a scientific consensus - may rely on abandonment of previous theories due to their irreconcilable differences. Having recently read Rachel Carson's 1950 The Sea Around Us I can offer some agreement: although Carson's geophysical analysis quietly screams in favour of plate tectonics, the contemporary lack of evidence lead her to state the no doubt establishment mantra of the period concerning static land masses.
What Burke constantly emphasises even more than his predecessors is that time and place has a fundamental influence on the scientific enquiry of each period. Being immersed in the preconceived notions of their culture, scientists can find it as difficult as anyone else to gain an objective attitude. In actuality, it is all but impossible, leading to such farcical dead-ends as Piltdown Man, a hoax that lasted for decades because it fulfilled the jingoistic expectations of British scientists. Burke's definition of genius is someone who can escape the givens of their background and thus achieve mental insights that no amount of methodical plodding can equal. Well, perhaps, on occasion.
The series also goes further than its predecessors in defining religion as anti-scientific on two grounds: its demand for absolute obedience in the face of logic and evidence, with reference to Galileo; or the lack of interest in progress, as with the cyclical yet static Buddhist view, content for the universe to endlessly repeat itself. Burke also shows how scientific ideas can be perverted for political ends, as with social Darwinism. But then he goes on to note that as the world gets ever more complex, and changes at an ever faster rate, non-specialists are unable to test new theories in any degree and so are having to rely on authority just as much as before the Enlightenment. How ironic!
All in all, these common threads are to my mind among the most important elements of the three series:
- Science and the humanities rely on the same basic processes of the human brain and so are not all that different;
- Scientific thinking can be as creative an endeavour as the arts;
- Scientists don't live in a cultural vacuum but are part and parcel of their world and time;
- Religion is the most change-resistant of human activities and therefore rarely appears sympathetic to science's aims and goals.
As Carl Sagan put it, "we make our world significant by the courage of our questions and the depth of our answers." For me, these three series are significant for their appraisal of some of those courageous explorers who have given us the knowledge and tools we call science.
