For centuries, Christian Europe was possessed by the notion that the universe was placed with the human-dominated Earth at its centre. Renaissance and later, Enlightenment, scholars emancipated European thinking from that constraining idea. Earth proved to orbit the Sun, and ultimately even the Sun was perceived to be but one object in an immense universe. The new ideas pushed the deity usually held responsible for creating the universe and those thinking about it into a more distant role. Harold Morowitz is having none of that. In this compelling study of how cosmology and life are subjected to a vast form of punctuated equilibrium, he takes us through the journey of 28 Steps, each increasing the complexity of the cosmos.
He explains the phenomenon of "emergence" - through the Steps from the Big Bang to human consciousness. Able to bend with ease mainstream science along the way, he also manages to restore Lamarckian "acquired characteristics" - once thought dismissed by Darwin's natural selection - and restores teleology, the notion that life and the cosmos have a "purpose" by just existing. These are serious challenges to mainstream thinking and should deserve a look except for Morowitz' own self-imposed short-comings.
The Steps are introduced with how investigations of complexity led to probing more deeply to find simpler conditions from which the complexity arose. Today, this is called "reductionism" - which for some is an epithet. "Emergence", Morowitz says, is the opposite of reduction since it portrays how complexity arises. He will, he declares, show how emergence has and will lead to increasingly higher orders of existence. Further, he will demonstrate how to forecast where they might lead. At this point, he drops his bombshell on the reader - the future will bring a new relationship with the deity that has dominated Western European thinking for two millennia.
The Steps are carefully built up from cosmic beginnings. They are logically structured and well explained. Number 1 is "The First Emergence" - the cosmic chaos that initiated this universe. He covers the evidence of what is known from physics in a mere four pages - a testimony to Morowitz' capacity to distil and declaim well. The succeeding Steps are also the result of physical analysis - that of the chemical elements, stars, solar systems and how to fashion a planet. On this planet, divisions arose, some deep in the interior and others on the surface - most notably, the geosphere and the biosphere. When life emerges, Morowitz does a bit of a shift, telling us that his attention will be on those Steps leading to humans and their capacity for reason. One primate species' capacity for language becomes the turning point - it's the prompt for the emergence of "culture". Culture, he says, that evolution from the Darwinian form back to the Lamarckian - traits can be acquired, not just genetically transmitted.
"Matter is informatic", the author declares, and attributes that capacity to the tinkering of the deity's "immanance" throughout the cosmos. The capacity for information is vastly enhanced when humans begin communicating, sharing ideas and proposing new ones. For Morowitz, this ability has been hampered by local, selfish considerations. He believes that if more of us come to understand the string of emergences underlying our existence, we will be able to set aside those short-term considerations. The purpose of that, of course, will be the attainment of a firm linkage with that divine immanance he's been threading through his narrative. The deity of Western religions, he notes, is volitional as well as deterministic. It's up to humanity to learn to be as volitional and enter the immanance as participants. That's a tall order and Morowitz has no illusions about the difficulties involved. In effect, he wants to return to the time when humanity declared itself to be at the centre of the universe because they believed a deity put them there. [stephen a. haines - Ottawa, Canada]
