Gravity Driven Cosmological Evolution and the Origin of Life

QUESTIONS

HISTORICAL NOTES

Faced with the awesome wonder and the hopeless complexity of nature, each of us must choose to be either a mystic or a logician - there is really nothing in between. There are of course those, most of us in fact, who have never seriously confronted the question, and there are those who, while publicly swearing allegiance to logic, privately reveal themselves to be crypto-mystics. If challenged some of us respond from deep in our hearts claiming that the world is intractable, ultimately defying all attempts at logical analysis, and will therefore remain forever a mystery. Others, in complete contrast, are convinced that nature inevitably must obey principles of simple logic and, although exquisitely subtle and mind-numbingly complex in its infinite variations and elaborations, it is ultimately tractable and comprehensible in the sense that it can be modelled by the rigorous application of mathematical and scientific analysis. Where can we seek guidance, perhaps even answers? What, actually, are the questions? Is there anything we have learned after 3000 years or more of organised enquiry on which we can base at least some tentative opinions?

Looking back we see that there is a direct correlation between man’s perception of his relationship to nature and the extent of his knowledge of it. Primitive societies tend to view themselves as part of an amorphous, mysterious cosmos which man can only hope to appease in order to survive and prosper. Developed but still pre-technological civilisations, with a significant literary and philosophical tradition, seem to regard nature as something abstract and virtually a product of human imagination. It was only when modern science and technology evolved that we were generally able to view nature as an independently analysable process which man can set out to understand, manipulate and occasionally re-fashion to his needs.

These three stages of knowledge correspond to the three main bodies of reference works which, still today, we consult. Needless to say, there is a good deal of overlapping between them, but they nevertheless function as largely independent sources. Today we would refer to them as religious mythology, classical philosophy and modern science. So where shall we start our search? In order to determine that, we have to decide precisely what we are searching for, and I shall now define our goal to be a strictly objective understanding of man’s place in nature. Religion gives us myths and fables. Classical philosophy, even of the modern variety, gives us dry and ultimately sterile musings about our mental and conceptualising processes; hopeless attempts to discover, by solitary reflection and introspection, the absolute truth. The genuine vocation of these two disciplines would realistically be to define a moral framework within which human relationships can function harmoniously. However their absurd, self-serving and ultimately self-defeating claims to omniscience, the revelation of an instant shortcut to perfect knowledge presumably made in order to bolster their “authority”, have only served to undermine whatever validity they might have had. Modern science alone, rather than pretending to provide answers, suggests a logically objective methodology, an investigative technique, a tool for probing concretely, physically, whatever is “out there” in our universe. This is true in spite of the fact that we must accept an element of interpretation in any human concept of anything. So with all that in mind, let’s briefly review our scientific achievements to date.

First I must make the point that, as opposed to the technology used to exploit nature, understanding is not gained as a smooth, continuous process, but by leaps of insight,
