1994, a credible physicist wrote an incredible book about the possibility of
resurrection, and what it would mean to be a consciousness that expands
without limit. It is a book
from which I learned a great deal of real science – cosmology, particle
physics, quantum mechanics and thermodynamics – as well as the mathematics
of computability. The book is
also sewn through with tidbits from history of religious and philosophical
thought, about which I knew little.
yearning for eternal life has been part of the human experience at least
since the dawn of history. Is
eternal life even a logically meaningful idea?
Life in this sense implies experience, and in a finite universe, it
would seem that there are only a finite number of experiences that can be
had? If we ran out of
experiences and started endlessly repeating them (after a phenomenally long,
but not infinite time), could this still be regarded as 'eternal life'? (The book describes this dilemma and several possible escapes
from it, ultimately eliminating all but one.)
it the destiny of life to expand beyond our planet and create new forms that
colonize the universe? Will the
very structure of stars and galaxies be molded by our descendants to serve
efficiently as a home to “life” broadly defined? Is our experience of selfhood dependent on the particular
physical form taken by our bodies and brains?
If there were a computer simulation of my brain (down to the last
quantum detail) would I experience this as "me"?
the broadest sense, self-reflection is the essence of humanity.
For those of us to whom science is a foundation of our

Those who knew a little of science in the 20th century imagined that the scientific endeavor would soon be able to explain the workings of the universe as a machine, thus draining human strivings of all meaning. To these people, godlessness became a religion, and despair a matter of faith. Human existence is absurd, declared the Existentialists, who claimed the mantle of scientific objectivity as their heritage.
But working scientists know better. A good scientific theory is one that resolves a mystery by replacing it with a deeper mystery.
“Try and penetrate with our limited means the secrets of nature and you will find that, behind all the discernible concatenations, there remains something subtle, intangible and inexplicable. Veneration for this force beyond anything that we can comprehend is my

"Let an ultra-intelligent machine be defined as a machine that can far surpass all the intellectual activities of any man. Since the design of machines is one of these intellectual activities, an ultra-intelligent machine could design even smarter machines, which in turn would create another, smarter generation; there would then unquestionably be an 'intelligence explosion,' and the intelligence of man would be left far behind. Thus the first ultra-intelligent machine is the last invention that man need ever make."
This is the premise of a
group of people gathering next month
at Stanford University to talk about the prospects of an imminent, dramatic
shift in human history, which they call The
Singularity. They build on the belief that, given enough
circuitry, computers are capable of all the subtlety and creativity and
intuition that characterizes human thinking. This is a question on
which reasonable men differ; in fact, it's a question on which there is
vigorous, heated debate with impressive credentials on both sides.
What do you think?

“You can understand and relate to most people better if you look at them – no matter how old or impressive they may be – as if they are children. For most of us never really grow up or mature all that much – we simply grow taller. Oh, to be sure, we laugh less and play less and wear uncomfortable disguises like adults, but beneath the costume is the child we always are, whose needs are simple, whose daily life is still best described by fairy tales.”

“Risking one's life can be strangely liberating. That's what the sea counsels me. She still talks even though she's got a mercury Superfund on her left breast and vinyl chloride and phthalates on her right breast. She's a forgiving grandmother. Not unduly angry about the mix-ups and mess ups and the confounding fact of healing taking so long. She knows it is complicated. My intent will keep her, she says.”
