These are excerpts and elaborations from my book "The Nature of Consciousness"
26. Finale: what does it all mean?
Epilogue: Piero Scaruffi’s Theory Of Consciousness I hope that this book is
going to be useful, first and foremost, as a survey, so that many more people
can be informed about research programs underway the world over. My own ideas,
as presented mostly at the end of each chapter, can be summarized as follows. First of all, two
fundamental principles. I
believe in the existence of a common underlying principle that governs
inanimate matter (the one studied by
Physics), living matter (the one studied by Biology) and consciousness (studied
by Cognitive Science). We know that the world of
living beings is a “Darwinian” system: competition, survival of the fittest,
evolution and all that stuff. We know that the immune system is a Darwinian
system. We are learning that the brain is also a Darwinian system, where the
principles of natural selection apply to neural connections. It is intuitive
that memory is a Darwinian system: we remember the things that we use
frequently, we forget things we never use. I think that the mind is a Darwinian
system as well: competition, survival of the fittest and evolution work among
thoughts as well. The Darwinian system recurs at different levels of
organization, and one of them happens to be our thought system, i.e. our mind. Biology and Physics offer us
different theories of Nature. Physics' view is "reductionist": the
universe is made of galaxies, which are made of stars, which are made of
particles. By studying the forces that operate on particles, one can understand
the universe. Biology's view is Darwinist: systems evolve. Reconciling the two
views is the great scientific challenge of the next century. The main addition to the
Darwinian paradigm that i advocate is a crucial role for endosymbiosis: I
believe that new organisms can be created by "merging" two existing
organisms. If each organism is made of smaller organisms, then it is not
surprising that a Darwinian law governs each level of organization: each
component organism "was" a living organism, and, like all living
things, was designed to live and die and evolve according to the rules of
Darwinian evolution. The organism that eventually arose through the progressive
accretion of simpler organisms is a complex interplay of Darwinian systems. It
is not surprising that muscles, memory, the immune system and the brain itself
all exhibit Darwinian behavior (get stronger when used, weaker when not used). A second fundamental
principle is "ex nihilo nihil fit": nothing comes from nothing. Life
does not arise by magic: it must come from properties of matter. Ditto for
cognition. Ditto for consciousness. Many schemes have been proposed to explain
how life or consciousness may be "created" from inanimate and
unconscious matter, how a completely new property can arise from other properties.
I don't believe this is the case. Both life and consciousness are ultimately
natural phenomena that originate from other natural phenomena, just like
television programs and the motion of stars. I believe that the substance
of the brain and the substance of consciousness are the same. Brain processes
and thoughts arise from different properties of the same matter, just like a
piece of matter exhibits both gravitational and electrical features. The
feature that gives rise to consciousness is therefore present in every particle
of the universe, just like the features that give rise to electricity and
gravity. Cognition is a feature of
all matter, whether living or not: degrees of remembering, learning, etc. are
ubiquitous in all natural systems. If you bend a piece of paper several times,
it will tend to stay bent. That is equivalent to our memory memorizing
something. If you leave it alone, the piece of paper will tend to resume its
flat position. That is equivalent to our memory forgetting some information
that is no longer used. The
issue, therefore, is not of what is conscious and what is not, of what is
cognitive and what is not: the issue is the “degree” to which a system is
conscious or cognitive. My degree of consciousness and of cognition are
different from those of a stone, of a cat, of a tomato plant. The
explanation of consciousness does require a conceptual revolution in Science,
specifically the introduction of a new feature of matter, which must be present
even in the most fundamental building blocks of the universe. I believe that
proto-consciousness is pervasive. Every piece of matter, down to the elementary
constituents, is proto-conscious. The reason we “feel” is that each atom of our
body “feels” (to some extent). Consciousness was there from the beginning. It
is not created inside the brain by some magic process. Each neuron, and each
atom of each neuron, is “proto-conscious”. And each atom of every object is
proto-conscious. The reason we are conscious is similar to the reason that some
bodies are electrical conductors: each single particle of the universe has an
electrical charge, and in some configurations that property yields
conductivity. By the same token, each single particle of the universe has a
proto-conscious quality, and in some configurations (for example, the human
brain) that property yields consciousness. My
explanation of where our mind comes from goes like this. If consciousness is
ubiquitous in nature, then it is not difficult to accept the idea that it was
there, in some primitive form, since the very beginnings of life, and that it
evolved with life. It became more and more complex as organisms became more and
more complex. Early hominids were conscious, and their consciousness, while
much more sophisticated than the consciousness of bacteria, was still rather
basic, probably limited to fear, pain, pleasure, etc. Early hominids had a way
to express through sounds their emotions of fear and pain and pleasure. Consciousness was a skill
that helped in natural selection. Minds were always busy thinking in very basic
terms about survival, e.g. about how to avoid danger and how to create
opportunities for food. What set hominids apart from
other mammals was the ability to manufacture tools. We can walk and we can use
our hands in ways that no other animal can. The use of tools (weapons, clothes,
houses, fire) relieved us from a lot of the daily processing that animals use
their minds for. Our minds could afford to be "lazy". Instead of
constantly monitoring the environment for preys and predators, our minds could
afford to become "lazy". Out of that laziness modern consciousness
was born. As the human mind had fewer and fewer practical chores, it could
afford to do its own "gymnastics", rehearsing emotions, and constructing
more and more complex ones. As more complex emotions helped cope with life,
individuals who could generate and deal with them were rewarded by natural
selection. Emotions underwent a Darwinian evolution of their own. That process
is still occurring today. Most animals cannot afford
to spend much time philosophizing: their minds are constantly working to help
them survive in their environment. Since tools were doing most of the job for
us, our minds could afford the luxury of philosophizing, which is really mental
gymnastics (to keep the mind in good shape). In
turn, this led to more and more efficient tools, to more and more mental
gymnastics. As emotions grew more complex, sounds to express them grew more
complex. It is not true that other animals cannot produce complex sounds. They
have the sounds that express the emotions they feel. Human language developed
to express more and more complex emotions. The quantity and quality of sounds
kept increasing. Language trailed consciousness. Ideas,
or "memes", also underwent Darwinian evolution, spreading like virus
from mind to mind, and continuously changing to adapt to new degrees of
consciousness. The
history of consciousness is the history of the parallel and interacting
evolution of: tools, language, memes, emotions and the brain itself. Each
evolved and fostered the evolution of the others. The co-evolution of these
”components” led to our current mental life. This process continues
today, and will continue for as long as tools allow more time for our minds to
think. The software engineer daughter of a miner is "more" conscious
than her father. And her father was more conscious than her ancestor who was,
say, a medieval slave. Consciousness is a product
of having nothing better to do with our brain. I also believe that the solution
to the mystery of consciousness lies in a fundamental flaw of Physics. The two
great theories of the universe that we have today, Quantum Physics and
Relativity Theory, are incompatible. They both have an impressive record of
achievements, but they are incompatible. One or both must go. I believe that
once we replace them with one unified theory that is equally successful in
explaining the cosmological realm and the subatomic realm, consciousness will
be revealed to be a trivial consequence of the nature of the world. And I
believe that this unified theory will be a “Theory of the Observer”, not a
theory of matter (as Physics has traditionally been). But that’s material for
another book. Alas,
in order to understand how I reached these conclusions you have to read the
whole book. Once you have all the facts and all the theories, you can decide by
yourself. And
let me clarify one more time: the vast majority of the book is not about my
personal beliefs, but about the findings and the theories of specialists who
know a lot more than me. In a sense, the goal of this book is to educate the
reader to the point that the reader can work out her own theory of
consciousness, cognition and life. What
do you think is the meaning of matter? Summarizing What Is Summarizable We don't really know why
that particular piece of matter, the brain, yields consciousness. After all,
the physical substance of the brain is made of the same elements found in all
animals (carbon, hydrogen, oxygen, sodium, nitrogen, phosphorous, iron,
calcium, potassium). I have proposed a way out of
this dilemma: to assume that a fundamental property of matter, of all matter,
allows for the rise of consciousness when matter is organized in a particular
manner. If consciousness is somehow present in each particle of the universe,
then we don’t need to explain the gap: there is no gap, just like there is no
gap between electricity and gravity, they are simply different aspects of
matter, which originate from different properties of fundamental particles. During our long excursion in
the maze of unsolved scientific problems, we progressively reduced much of our
behavior (from common sense to emotions, from dreams to intelligence) and even
life itself to a more and more mechanical process of interaction with the
universe. The “Darwinian” theme kept coming back over and over again: we are
the way we are not because somebody designed us that way but because a
fundamental “force” of the universe allows for the survival of only those
things that “fit” with the rest of the universe. The behavior of body and
“mind” is actually very similar, once one takes this “Darwinian” perspective:
both bodily organs and mental phenomena are bound to be what they are because
they are useful for our survival, and both were shaped by external forces. We are but small cogs in the
gigantic machine of the universe. We don’t live, we survive. Ultimately, we don’t live,
we are lived. Even worse: we don’t think,
we are thought. We had to go through a
cathartic reassessment of our role in the world (the Earth is not the center of
the universe; man was not created by God; man is not the dominant species; the
brain is just an organ; experience molds the brain) before being in a position
to find what is truly unique about the human experience. The final mystery is what
this is all about. If we are but cogs in a huge machine, if our “minds” and
bodies are but small machines that are part of a much bigger machine, what is
this huge machine for? The very meaning of life,
the fundamental "why" of Science, can be rephrased as follows. Both
the mind and the universe are machines that are computing something. What? A Word on Miracles When I discuss Einstein's theory of Relativity with people who have no scientific background,
my words are invariably met with a degree of skepticism, notwithstanding
Hiroshima and all the other tangible proofs of its validity. On the other hand,
mention a "miracle" to the same folks, and they will believe in it
(to some degree) on the spot. By "miracle" I mean anything that
eludes scientific proof, from telepathy to religious beliefs. What is it that makes
miracles so convincing, even if, over and over again, "miraculous"
events and phenomena of the past have been explained rationally by science and
proved nothing outside of the ordinary? Miracles tend to occur only
in places where there are no reliable news agencies and never in front of a
video-camera. And they cannot be performed in front of scientists, but only in
front of audiences that know little about Physics and Chemistry. Not a single case of
telepathy or levitation has been documented scientifically (the way one
documents a flue outbreak or a car accident). Yet, most people believe they
occur. The same people are often skeptic about Einstein's Relativity, no matter how many experiments have confirmed it. Why does the human mind
prefer miracles over science? Human brains do not like
scientific formulas, they like legends, stories, metaphors. The moment a
scientist produces a rational explanation for a purported miracle, people need
a new myth to replace it. Newton's and Einstein's brains were working
unlike the brains of most people in that they were looking for rational
theories to supplant myths. The ordinary brain needs
miracles. Miracles are hallucinations, random hallucinations, that have fed the
brain since ancient times. Most brains don't know how to work without those
hallucinations. Most brains cannot work in a purely logical manner, most brains
need that irrational element. Our brain is still very much
dependent on the hallucinating voices that come from nowhere, have no
explanation and prompt us to experience new behavior. The Newtons and Einsteins
were geniuses because they achieved a higher level of consciousness in which
every miracle is questioned and no myth is ever generated. In those brains, the
hallucinating voices have been reduced to only one, which expresses their quest
for rationality. The chaotic noise of the hallucinating voices has been
replaced by the ordered silence of logical thinking. Not An Epilogue People often ask me:
"Do you believe in God?" I reply: "Do you
believe in zestykistirism?" They say: "What's
that?" Precisely: "What is
God?" First of all, people should
define what they mean by “God”. As people struggle to define it, they often end
up with such a vague definition that pretty much anything in the cosmos
qualifies. The moment they try to be more specific, they fall into all sorts of
traps that negate the very essence of the “God” that they are trying to define. Sometimes, in order to avoid
the logic around their own definitions, people claim that our minds cannot
grasp the concept of God: if our minds cannot grasp the concept of the divine,
then we have no clue what this God expects from us, thus the question is
pointless. The gods we worship (the
Christian god, the Jewish god, the Islamic god, etc.) were invented by humans.
They are reflections of humanity. They are as “human” as us. We assign them the
moral values that we “value”, the values that our mind can grasp. If
superbeings exist, they are unlikely to be like anything we can envision, and
such a superbeing could even be upset that we worship all these “human” gods. (I also confess a deep
antipathy for monotheism: I have always found the ancient polytheistic
religions to be much more “civilized”, i.e. tolerant and rational, than the
tyrannical and dogmatic monotheistic religions of the Jews, the Christians and
the Muslims. Mecca before Mohammed, where all “idols” were worshiped, is my
ideal. Mecca after Mohammed, when all “other” idols became taboo, is my
nightmare). Thus the question about our
“souls” and what happens to them after death is also meaningless. For the sake
of arguing, one could ask what qualifies as a “soul” and what does not. The
majority of religious people would probably reply that only humans qualify.
They would claim that dogs have no soul, and worms have no soul, and spiders
have no soul: these species do not go to paradise or hell, they simply
disintegrate in the soil. Ditto for all the species that preceded Homo Sapiens
Sapiens. The evidence? They can’t speak, build cities, write books. One could
ask: what about superior species? What if a new species appeared, that looks
like a turtle but that is capable of doing everything we humans do (writing
books, building cities and so forth) plus many other things that we humans
can’t do (reading minds or seeing in four dimensions or levitating). Would this
species qualify for eternal life in paradise? If yes, then we reach the rather
unpleasant conclusion that the human species is the “lowest” form of soul:
anything inferior to a human being does not have a soul, while anything
superior to a human being has a soul. If not, we reach the rather bizarre
conclusion that, in order to have a soul, a being must be exactly like a human
being, no less and no more: give or take a cognitive faculty and the being
becomes a soul-less being. Either answer is unconvincing. The logical answer
would be that every form of life is just that: a form of life. There are
degrees of consciousness, emotion, feelings, and even of being alive. Some
living beings are capable of things that other living beings are not capable
of. And in the future new forms of life may appear, capable of actions that we
are not capable of. A Word On Mysticism Sometimes the final proof of
the existence of some divine force is ascribed to states of ecstasy, whether
achieved via collective hysteria or some kind of drugs. What collective hysteria
and hallucinogenic drugs have in common is that they, basically, paralyze parts
of the brain, so that your perception is reduced (ironically, the opposite of
what some psychedelic gurus used to claim) and your ability to perform
reasoning is even further reduced. In other words, they make you dumber. As you
become dumber, you have visions of God. Somehow the fact that one has to
surrender her/his brain in order to grasp the existence of God makes me think
that God is a remnant of a pre-human state of existence, one in which humans
were not “sapiens”, i.e. did not think the way they think today. I get the
feeling that one can grasp the sense of God only if s/he returns to the state
of mind of primitive hominids. Perhaps all apes believe in God, because their
brain is permanently in the state in which religions and psychedelic gurus want
our brains to be. Perhaps all lower mammals, that do not have the neo-cortex
and our cognitive faculties, “feel” God. Religion could simply be an
evolutionary leftover, governed by the older part of the brain and superseded
by reason whenever we let the newer part of the brain take over. What
is unique about humans is the elaborate rituals (involving dancing, chanting,
drumming, funeral processions, masses for the dead, decorated tombs, etc) that
they built around their ecstatic experiences. And the way that humans
rationalized their ecstatic experiences into three fundamental “religious”
beliefs: 1. That gods created the universe; 2. That humans are entitled to an
afterlife; 3. That pleasing the gods will make the afterlife more pleasant and
even eternal. Is this due to the interaction of the new rational brain with the
older irrational brain? Is this the rational brain trying to make sense of the
irrational brain? Humans
seem to live under the control of two genetic programs that operate in
different directions. The newer genetic program, implemented as the neocortex,
wants humans to be rational, while the older genetic program, implemented as
the lower brain functions, wants humans to be irrational. The entire human
civilization seems to be the outcome of this interplay between the rational and
the irrational brain. Humans are maybe just a transitional species, between the
irrational brain that has ruled the planet for millions of years and a new
category of rational species, that will rule the planet for the next million
years. Emotions
are very ancient and they are progressively disappearing. The
real appeal of studying religion for a scholar might be that it represents an
earlier form of “thinking” in evolution. What
is probably unique to humans is that we are not only mystical but believe in
supernatural beings. Human brains are equipped with the faculty to create a
“theory of mind”. We can speculate on what another person is thinking, and in
many case we get it right. That faculty is due to our brain's ability to expect
and recognize patterns of behavior. We then apply the same logic to
"animate" objects, for example a tree that is swinging and making a
sound because of the wind, or a thunder, or the moon. We assign them a mental
life. (As we grow up we learn, or are taught, that they are not sentient
beings). That is the origin of the spirits that populated Nature in primitive
societies. Our brain naturally tends to explain a pattern of movement as caused
by a mind. We recognize things not as objects but as subjects. When we see the
pattern but don't see the "thing", we assign minds to invisible
subjects, such as gods. Monotheism is the belief that the pattern of all patterns
has a mind, is a subject. What Does It All Mean? What does it all mean? Is
there an afterlife? I have a feeling that a) we cannot comprehend it, and b)
the questions are not framed correctly. We cannot comprehend it because some
things are beyond our cognitive closure, just like a snake cannot see in three
dimensions and we can’t see some colors of the spectrum. And the questions are
not framed correctly because they refer to objects that are either not defined
or improperly defined. Sometimes the logic is also odd: we are concerned about
the afterlife, but seem indifferent to the “pre-life”. We are scared that we
will never exist again, but we are not scared that we never existed before. The
eternity “after” our death terrifies us, but the eternity “before” our birth
does not terrify us. Inevitably, one feels that our terror is programmed in our
instinct for survival. When i wonder about the afterlife, i am just a machine
programmed to avoid death. It gets even worse if i
meditate. When i meditate, i do not find peace at all: the fear of death
increases, not decreases. But the more i meditate the more i realize that i
also fear eternal life. It would be equally terrifying to live forever and ever
and ever. In other words, i fear any non-human condition. I am a human being,
programmed to live the finite life, and to desire the finite life, of a human
being. I do not envy an angel’s
eternal static life. I do not envy an angel because i am not controlled by an
angel’s genome. I am controlled by the human genome. If i really had to imagine
an afterlife, i wouldn't want to just be an eternal spectator on another
dimension. I would hope that each of us can become a god herself or himself,
and create her or his own universe. That would somewhat alleviate the boredom
of eternity. Is there extraterrestrial
life? We first have to agree on what “life” means. If we mean “Earthly life”
(the thing we call "life" here on Earth), then how much of it is
enough to qualify as "life"? What thing between the fundamental
constituents of life and a human being is enough to be considered
"life"? Depending where one places the border, the chances of
"life" existing somewhere else change dramatically. Do the
constituents of Earthly life exist somewhere else? Absolutely. Do humans exist
somewhere else? I do not think so, because it takes a very similar planet
located near a very similar star at a very similar distance with a very similar
geological history and a very similar history of astral encounters for billions
of years to lead to human beings. (Calculations of the probability of Earthly
life occurring on other planets routinely overlook the billions of cosmic
events that shape the history of a planet). If "life" does not
have to be the kind that we find on this planet, then the question is what
qualifies as "life" that is not made of the constituents of Earthly
life (aminoacids and proteins). Since just about everything in the universe
grows and decays to some extent (from rocks to Earthly life), just about
everything can be squeezed into a broad definition of "life". Is a
rock alive? Why not? It does change over time by interacting with the
environment. It does multiply when it breaks into many pieces. It is just that
Earthly animals do the same thing in a way that to us, Earthly animals, appears
more complex. The behaviorist approach is
to define "life" as something that we would recognize as life because
we can communicate with it to some extent. We cannot speak to a cat, but the
cat reacts to our actions. That reaction tells us that the cat is
"alive" (as opposed to a rock, that does not react and therefore we
don't consider alive without any need for a biological definition of
"life"). The problem is that
communication too is a vague concept. Everything, ultimately, interacts with
everything else. What degree of interaction is enough to qualify as
communication? My feeling is that we are
using an Earthly term for non-Earthly processes when we should simply use a
different name. Earthly life is just one of the many processes that can be
found on planet Earth. There are many other processes, most of which have no
name because we are not interested in naming them. For example, the way rocks
decay on planet Earth is probably unique, but we have no name for the process
of rock decay on planet Earth. You and I are not rocks, so we have no interest
in giving this process a name. Other planets simply host
different kinds of processes. I feel that it is misleading to try to impose the
term "life" (a term invented for an Earthly process) on whatever
non-Earthly process. Why not just give it a different name? How Will It End? The Future Evolution Of Humans – Part I I
am frequently asked about the future, about what is going to happen to humans
in the future. Most futurologists simply reply that humans will self-destroy
and will be replaced by a better race. That is a nice way to avoid figuring out
what our civilization will be like millions of years from now. I do not believe
that we will self-destroy, but i do believe that we will be replaced by newer
and newer “races”, descendants of our race (or, better, species). In the short term i believe
that humans will evolve into more and more conscious beings. I see this as a
consequence of interaction with other humans and with the cultural specimen
that other humans leave behind. The more we think the more… we think. It is a
vicious loop that started when humans had the first philosophical conversation.
We are more and more conscious of the human condition, of our (minuscule) role
in the universe and of death. I see this trend continuing to degrees that today
we can’t even imagine. Homo Conscious is the successor of Homo Sapiens. At the same time, i believe
that some kind of regression in civilization will occur as a consequence of the
stabilization and possible reduction of human population. Basically, i think
that civilization was a result of population explosion, a self-sustaining
positive feedback: as humans multiplied, each individual had to content herself
with a smaller and smaller territory. Civilization was the art of making more
of less. As an individual’s territory shrank, he had to come up with more
efficient means to provide for himself and his family. I believe that this is
what civilization is all about. This process has been going for thousands of
years, as the territory of an individual shrank from entire forests to an
apartment in a high-rise building (mostly not even owned, but only rented).
People work because they can no longer rely on a natural profusion of food and
materials: competition with other humans has been making those resources
scarcer and scarcer. This has triggered human creativity, and caused the advent
of science and technology, and everything else that we call “civilization”. Once this process is
reversed, I believe that civilization will reverse too. An abundance of natural
resources would automatically defuse human creativity. Thus i foresee a near-term
future (a few centuries from now) in which humans will become more and more
conscious while being more and more “savage”. How Will It End? The Future Evolution Of Humans – Part II In a few centuries or
millennia, I think that humans will have to face another “intelligent” species.
I am not referring to extraterrestrial life (if it exists, it is just so
unlikely to interact with Earthly life until we start traveling very long
distances). I am referring to descendants of species that exist right now on
Earth. I believe that some of them will eventually become “intelligent” enough
that humans will have to consider them as equal as, say, very dumb people
(ubiquitous in every continent, and often even elected to office). I believe
that other animal species will eventually evolve the ability to create
civilizations, more or less similar to the ones created by humans (minus human
language, of course, which will remain a human peculiarity). I have a hunch
that birds (rather than mammals) are the best candidates for such a
breakthrough: they live in large societies and they travel long distances. Somehow,
i feel that these are prerequisites to the emergence of a higher form of
consciousness. I don’t think humans will
ever have to share their world with aliens, but i do think that humans will
eventually have to share their world with other Earthly species as capable as
humans of building civilizations. How Will It End? The Future Evolution Of Humans – Part III We can argue forever about
what happened during the evolution of the human brain, but what happened to the
human body seems pretty clear: it got bigger, and it is still getting bigger,
generation after generation. Of course, diet matters. But diet mattered also
millions of years ago. It is part of the story of evolution. We tend to focus on the
evolution of the brain, not on the evolution of the body, but i think that the
brain evolves to serve the body. Therefore i am interested in finding out the
ways in which the human body can evolve. At the same time, i have
always been intrigued by the fact that this human race, so good at expanding
beyond its original environment, has scant chances of expanding beyond our
neighborhood (the Solar System), of ever exploring the universe: we are too
small and our lives are too short for us to conquer unlimited space and time.
It is difficult to believe that any kind of scientific progress will allow such
small and brief beings to reach any other galaxy. One day I finally realized
the simplest way that humans could colonize the universe: if they evolved into
bigger beings, their task of explorers would be much easier, just like an
elephant can more easily travel long distances than an ant can. It is not a
question of brains, it is simply a matter of size. If humans evolve into a race
of giants (giants the size of planets), then they will be able to explore space
by simply “taking a walk”. These giants, who will eat planets and drink comets
(and live millions of years), will be able to “hike” from galaxy to galaxy. If
they invent their own transportation system, they might be able to cover
distances of billions of light years. (Is this impossible according to
Relativity? It is difficult to tell if Relativity, and any other human science,
is a true representation of the universe as it is, or just the best
representation of the universe as today’s humans see it). Of course, this is
not something likely to happen in the next few millennia. But i do think that the
problem of space exploration will be solved by biological evolution, not by
technological evolution. I think the former has higher chances of succeeding
than the latter. Technology will reach a point where improvement will come at a
slower and slower pace, unless it is matched by significant biological
evolution. On the other hand, biological evolution may speed up in response
to climate change or some galactic event,
and the current trend towards bigger bodies may get amplified ten-fold. Over
millions of generations, I can visualize descendants of the human race that
managed to survive all possible catastrophes and got so big (millions of times
bigger) that they have become cosmic objects and roam the universe the same way
that we roam the Earth. They will know about us, the
same way we know about the fossils of species that preceded us. They will know
of our civilizations, or, better, the fossils of civilizations that preceded
theirs. They will study us the same way we study a fossil. No matter how much
information we produce in no matter how many different media, our fossils will
look devoid of crucial information that is relevant to them for the simple
reason that we cannot conceive of the information that will be relevant
millions of years from now. But all of this is a big
“if”: if our form of life survives long enough. Unfortunately, it is also
likely that life on Earth will eventually be destroyed by a galactic
catastrophe and nobody will ever know that we existed. How Did It Start? It is popular to claim that,
thanks to the advent of the human race, the universe has somehow acquired
awareness of itself. After billions of
years of blind and dumb evolution, the universe finally created us humans, who
are endowed with the faculties of consciousness, and therefore in us the
universe has created a part of itself that is aware of the whole. That's a human-centric view
that is difficult to prove. It could well be that the universe has always been
aware of itself, and we humans are just the current manifestation of that
self-awareness (one of the current ones). And it could well be that we
are "not" aware of the universe but just of our little niche. Prologue I also envision another
possible future, but it is harder to explain. If we are part of the
universe that we study, and we are becoming more and more conscious of what the
universe is and does, and more and more of the universe is becoming “us”, then
maybe the “what” is a process of self-discovery: the universe is going
through a pain-staking process of
self-discovery. As conscious life triumphs over unconscious matter, the entire
universe will become conscious, aware of itself. In a sense, we are just
waking up, as if after a long sleep, and slowly beginning to realize where we
are and who we are. Thankfully we cannot
understand why. Thankfully we cannot understand the universe. Back to the index of all chapters |
