Homo sapiens: Born of the earth
- The key success is the possession of the most complex structure on Earth: the human
brain. Weighing a mere 1.5 kilograms and occupying the space of two fists, the brain
consists of 100 billion neurons. Each neuron can form up to 10 000 connections with
other cells, thereby creating the potential for more combinations than there are stars in
The Brains need for order
- Jacob, the French molecular biologist and Nobel laureate, suggests that the human mind
is far more; it has a built in need to create order out of the constant flow of information
coming from its sensory organs.
- The brain selects and discards information to be used in the narrative, constructing
connections and relationships that create a web of meaning. – A narrative reveals more
than just what happens’ it explains why.
- The physical world is approached from opposite ends in two cases: one is supremely
concrete , the other supremely abstract; one proceeds from the angle of sensible
qualities and the other from that of formal properties- Claude levi-strauss.
Weaving a World View:
- Knowledge of every human being accumulates through generation of observation,
experience and conjecture, was a priceless legacy for survival. Small families of
nomadic-hunters depended on skills and knowledge that were profoundly local,
embedded in the flora, fauna, climate and geology of a region. This information was
woven together into what is called a “Worldview”- a story whose subject for each group
is the world and everything in it, a world in which human begins are deeply immersed.
Each worldview was tied to a unique locale and people who had shaped Gods.
- Every worldview describes a universe in which everything is connected with everything
else. Stars, clouds, forests, oceans, and human beings are interconnected componenets
of a single system in which notion can exist in isolation.
- Human beings hold enormous responsibility’ each individual is accountable and every
action has repercussion. Past, present and future form a continuum in which each
generation inherits a world shaped by actions of its forebears and holds it in trust for all
generation to come.
The Capernican Revolution:
- For thousand of years people saw the world as the center of their worldviews.
- Then in 1523, Nicolaus Copernicus presented a new view of the cosmos, and
humanity’s place in it, in his book, “ on the Revolution of Celestial Orbs. His story had
the sun as its center, circled by planets. In 1610, Galileo Galilei published “ the starry
messenger” – in which he announced his discovers about the nature of the moon, the
composition of the Milky Way and the “ new stars” circling Jupiter- evidence to support
- The earth was marginalized-reduced to one for many planets in a universe filled with
other suns. This revolutionary cosmology demolished the intellectual and moral order of
the Western world
- The medieval view of the universe as fixed and finite, with humankind enshrined at the
center as God’s special creation, was replaced by a infinite universe- a boundless region
filled with darkness and space- and human beings were relocated to very inferior
- After Copernicus, the great physicist Isaac Newton discovered laws governing the
movement of bodies and the behaviour of light that appeared to apply everywhere in the
