Sigmund Freud.
Now,
all of this may seem bad enough, but it gets worse. The third significant way
in which science eroded religion came when science began to understand the
workings of the human brain. Humans had long felt that many things in this
world could not be explained in physical terms because they had long known that
inside the privacy of their minds, they had dreams and feelings, and even outside
in physical reality, they sometimes saw or did things, that by logic alone made
no sense. Cruel or lustful thoughts and acts were bad enough. But at least they
seemed somewhat predictable, given humans’ “sinful” nature. From long
experience, we’ve come to know our instinctive human drives, so we can often accept
intermittent thoughts of fornication, theft, violence, and even murder as
natural. But people also have much weirder dreams and even see weird things when
they’re wide awake that are, by the laws of physics and common sense, not
possible.
Why
do people have dreams and waking visions of angels or demons hovering in the
air, or of talking cats on mountaintops bathed in orange light and standing on
their hind feet? Night after night, many of us dream not just cruel or lustful
dreams, but also many more that are simply absurd. Other people, wide awake,
see angels, demons, and miracles. For centuries, if a person saw or did
something that afterward he himself could not make sense of, the widely
accepted explanation was that God (or Satan) had caused the event or had made
him do the deed. Much of normal human experience, apparently, lies beyond science
and even common sense.
When
Freud came along, his big contribution to human knowledge was simply the
proposition that all these perceptions come from inside the brain of the person
having the dream or vision. Thus, visions and miracles can be easily explained.
They come from stored-up memories that combine and recombine to form symbolic
narratives that are driven by deep, unconscious needs—needs that the visionary
isn’t aware of because they are buried so deeply she can’t consciously access
them, no matter how she tries. Under stress, her brain transmits images into
her optic nerves, which is the opposite of what usually happens. Thus, even
wide awake, we can sometimes see what in physical reality is not there.
Most
of our memories may not be recallable at will, but they are all in there.
Unless a person has had some brain-destroying injury or disease, her brain
holds all she has ever experienced, all the sense data that have ever been fed
into it via sight, sound, touch, smell, and taste. How they will affect her
moment-by-moment flow of consciousness can’t be exactly predicted in advance,
but the patterns in those “paranormal” experiences coincide too often and too
closely with the subject’s personal issues for us to believe that those
experiences are somehow independent of the mental states that preceded them. People have visions of angels when they have been reading about miraculous cures for the very troubles that they have been suffering under for the last six months. They dream of tidal waves after watching a t.v. show about the recent big one in Japan. They see the ghosts of their dead fathers after spending days feeling guilty for how they neglected him while he was alive - just before what would have been his 80th birthday. The sciences of the mind have shown convincingly that we can literally see
what we want/need to see.
While
at first, Freud and his followers were widely considered to be sex-obsessed
crackpots, they soon began to gain credibility and command respect, mainly
because they were getting results. Their model could explain all of human
behavior, they could make high probability predictions about how individuals
with certain backgrounds would act in specific future situations, and they
began to cure people of neuroses and psychoses that, in earlier times, would
have been pronounced hopeless.
Then,
as research on the human brain advanced, other researchers showed that the
model portraying all of a person’s experiences as being stored in his brain, even
though he can’t recall the experiences at will, is literally true. Patients
willing to stay conscious during neurosurgery, allowing researchers to place tiny
electrodes on their brains, are able, when a milliamp current is turned on, to
recall all kinds of memories in detail, memories of which they ordinarily have
no conscious awareness.6
Freud
went much further with his psycho-sexual explanations of nearly all of the
motives that drive human behaviour. Much of what he had to say has today been
discredited; for example, we no longer believe that little girls are consumed
with a desire to have a penis. But the larger impact of his discoveries
remains. Those parts of human experience that for so long had seemed to defy
logic and common sense turned out to have a rational explanation. The dreams
and visions were, and are, figments of overactive human imaginations; they
never actually took place at all. No more miracles.
If
we consider just these three scientific theories—Galileo’s, Darwin’s, and Freud’s—what
can we say have been their consequences? Copernicus, Galileo, and Newton, for
most people, removed the biblical God from their picture of the cosmos. They
didn’t need him in their model of the universe. Darwin removed God as the
creator of life. He even reduced humans to just one more kind of animal. And
Freud made humans look like sick animals, easily deluded by their own
aggressive, lustful, self-absorbed thoughts. (Donald Palmer’s book articulates
this idea well.7)
Despite
all this, science has not proved that the existence of God is impossible or that
a universal moral code is impossible. But over the past four centuries, science
has severely shaken the traditional idea of God and thus, inevitably, the
traditional ideas of morality (the two are deeply intertwined, as we shall see).
However, let me stress again that what does not
follow from these scientific models is that there is no God or that every form
of theism and every form of moral code are mere wishful thinking. We just need
a new understanding of what God is and what the fact of God’s existence should
mean for us in how we live our daily lives, an understanding that incorporates
some subtler ideas of God and science into a single, consistent, coherent
picture of what we believe is real.
But
for now, we can say that science has almost levelled the old, pre-Enlightenment
ways of thinking of these things. And let us make no mistake about what the
loss of their belief in God has done to the vast majority of ordinary people.
Removing God from Western society’s generally accepted picture of how the world works had the inevitable consequence of removing our society’s confidence
in its moral code, our ideas of what right and wrong are, and how we should try
to act—toward the world in general, but especially toward one another. If the moral
rules we’re supposed to follow aren’t God’s rules, whose rules are they? Human
authorities’ rules? Which human authorities? Who are they to be telling me what
to do?
The
point may seem a rather trivial one to most people in the West. Why should we
care whether the old ideas of God and right and wrong are crumbling? Explaining
in more detail why humans throughout the world, sometimes at deep, subconscious
levels, are struggling to cope with this loss, even though they may not be
aware of the philosophical names for the thoughts and feelings they are having,
will be the business of the next chapter.
