These are excerpts and elaborations from my book "The Nature of Consciousness"
Idealism According to idealism, mind
is the only substance that makes up all of reality. The German philosopher
Gottfried Leibniz (17th century) believed that only minds exist. Humans are not the only ones to have minds.
Everything has a mind. Even matter is made of minds. Minds come in degrees,
starting with matter (whose minds are very simple) and ending with God (whose
mind is infinite). Reality is the set of all finite minds (or
"monads") that God has created. Everything has a mind. This extreme
view of idealism is called "panpsychism". One way to get rid of the
mind-body problem was to get rid of the body. The Irish philosopher George
Berkeley (18th century) thought that all we know is our
perceptions, and whatever concepts we can build up from them ("esse est
percipi"). We cannot directly know that there is an external world. We
only know the internal world of our perceptions. When we talk of an object, we
talk of what we see, hear, taste, touch, smell: we talk of something that is
inside our mind. An object is an experience. The whole universe is a set of
experiences. Ultimately, the only thing that exists is the experiences of our
mind. In the 1920s the British
mathematicians and philosopher Alfred Whitehead proposed that mental life
occurs in a field of protoconscious events. His units are similar to Leibniz's
monads, but they are limited in time, and therefore better thought of as "mental events". Mental life is
a sequence of such mental events that occur in this mental space. As brain studies have proved
that the senses present us with a fictitious view of the universe, and
subatomic Physics has shown that matter is but clouds of floating particles,
and Quantum Mechanics has stated that reality is ultimately in the observer's
mind, it has become more tempting to embrace idealism. If everything we see and
hear is but an illusion, how can we claim that there really are
"things" out there? The only thing that we perceive is what the
senses fabricate for us. What we call "reality" is the work of our
mind. If Physics even predicts that reality cannot be "measured"
without an observer (as Quantum Mechanics does), how can we claim that reality
exists independent of our mind? The problem with idealism is
that one cannot do much more than claim to be an idealist. Once that claim has
been made, reality cannot be used to prove it, since reality is a mere illusion
of our mind. Everything is an illusion, including the things that one could use
to prove this statement right or wrong. Most scientists believe in a
milder form of idealism: the senses do fake reality, and reality does need an
observer to become what it is, but sensations do relate to an external world
and measurements do measure an external world. The senses and the brain simply
alter reality so that we can move about and survive in a world that we can
comprehend and manage. And Quantum Physics does not forbid reality from
existing, it only forbids us from completely perceiving it. Most scientists believe that
the reality that we perceive is indeed a fabrication of our mind, but it does
correspond to a reality out there, that exists regardless of our mind. Back to the beginning of the chapter "Mind and Matter" | Back to the index of all chapters |
