WHO ARE YOU? – Orval’s
Sermon on July 15, 2012 at UUCSP
Who Are You??? I’m not asking for your
name, like a police officer, or what you put on a business card. No, I’m asking
like the caterpillar in Alice in Wonderland. Who? – are? - you??? Yogananda, in
his “Autobiography of a Yogi,” says “Who Are You?” is THE best question upon
which to meditate.
What is the nature of Consciousness?
How do you make decisions? Do you have free will? THE most discussed topic in
philosophy throughout history and now is free will. Today I will add my own
perspective on the ancient questions of consciousness and free will and relate
some of the latest answers from science.
Our intuitive ideas of who we are may
be wrong, just as our idea that the sun revolved around the earth was proven
wrong. Most people believe in dualism; they think the mind and the body exist separately.
People say “I HAVE a brain” and “I HAVE a body.” And, my personal favorite: “I
changed my mind.” Who is the “I” that has a mind, that it can change? As if this
“I” is something other than our mind. Who are you? “We are spirits in a
material world” says the song by Sting. However, science has discredited the
theory of dualism. We now know that if you damage parts of the brain, there are
specific effects: there is no memory, self-control or decision-making. In other
words, no brain, no you. If you stick a fork in it, you are done. Think of mind
& brain like layers of computer hardware and software. Hardware is useless
without software and software is useless without hardware. The mind is what the brain does.
To answer the questions of free will
and consciousness, I turn to biological research: 1) Consciousness, a sense of
self, arises from an organism’s interactions with its surroundings. And 2) Free
will arises from an organism’s attempts to survive in a prey-predator
environment. What I like about this approach is that it provides a unified
theory to explain humans and animals. And it grounds free will and
responsibility in physical survival, not in some abstract moral plane.
Organisms, including human beings,
have to know which portion of the incoming sensory stream results from its’ own
actions and which does not. When you move your head, the world appears to stay
still. You can’t tickle yourself because you know you are touching your stomach
and therefore you are in control. We are not robots responding predictably to
external stimuli. All organisms that survive must be unpredictable for
competitors, prey or predators, as well as able to explore hidden resources. Recent
evidence indicates that one common ability of brains is to choose among
different behavioral options even in the absence of differences in the
environment and to perform genuinely novel acts. For instance, isolated leech
neurons subjected to identical electrical stimuli generates either a swimming motor program or a crawling motor program. What these variable
results tell us is that the animal behaves as it damned well pleases, sometimes
swimming and sometimes crawling, in an unpredictable way.
Animals and humans constantly ask:
What happens if I do this? The
experience of willing yourself to do something and then successfully doing it
is how you develop a sense of self and that you are in control. The
concept of self necessarily follows from the insight that animals and humans
initiate behavior by themselves. Agency
is assigned to entities who initiate actions themselves. Thus, agency is crucial for moral responsibility.
Behavior can have good or bad consequences. The law of the jungle is “eat or be
eaten;” an animal is responsible for its own survival. It is the agent for whom
the consequences matter the most and who can be held responsible for them. This
is one scientific model of consciousness and free will.
Who - are - you? The Buddhists figured
this out a long time ago, in what is now called “the bundle theory of the self.”
This theory holds that you are a collection of traits and characteristics held
together by the bundle of your body.
Everyone knows about right brains and
left brains. Well, science now speaks of many modules within the brain that are
specialized functions or capacities which all run simultaneously, mostly
subconsciously. You hear me, see me, feel the seat under yourself, pump your
heart, and digest your food, all at the same time. Our brains, then, are like a
tool box, with many tools available, many ``small minds'' that simultaneously
process feelings, fantasies, ideas, fixed routines, interpersonal responses and
bodily skills.
Around 1960, researchers
found that some people suffering from severe epileptic seizures could be cured
by surgically severing the connections between the right half and the left half
of the brain. Science has discovered that the optic nerve from the right eye
goes to the left brain, and the optic nerve from the left eye goes to the right
brain. In a normal, undivided brain, this information is subsequently shared
between halves of the brain. A patient who had the divided brain surgery was
shown a picture just to his right eye, which is connected to the left brain,
where the speech module is located. The patient said he saw a picture of a
chicken, and picked a chicken claw to match it. Then the patient was shown a
picture of a snowy winter scene just to his left eye. He said he saw nothing,
but he could correctly point to other related pictures, and picked a snow
shovel. He was asked why he picked pictures of a chicken claw and a shovel. The
patient answered: “Oh, the chicken coop is messy and I need the shovel to clean
it out.” Instead of saying “I don’t know,” we just make up a plausible story.
This was the first
experiment to demonstrate the existence of an Interpreter module or function in
our brains. Whatever we do, the interpreter makes sense of it. The Self is a sort of public relations agent,
a spokesperson but not a boss.
I used to object when people said
“part of me wants to go out, and part of me wants to stay home.” I thought that
was ridiculous because there was only one person. Now I’ve learned we are composed of parts, and part of us
really does want to go out while another part of us wants to stay home.
Here is a fun fact: We don’t know where thoughts come from!
Seriously, researchers don’t have a clue. Thoughts just seem to bubble up from
the subconscious and appear to consciousness. Much of our behavior is not
governed by our conscious mind – which is prone to claim credit – but by a
cauldron of motives, drives and unconscious propensities of which we are
largely oblivious. Indeed, most of our actions are carried out by the
unconscious minds.
Scientific
experiments using brain scans have proven that we unconsciously make choices
before we are consciously aware that we have decided. Most neuroscientists
today argue free will is an illusion. Sam Harris, neuroscientist and author,
says: “How can we be “free” as conscious agents if everything that we
consciously intend is caused by events in our brain that we do not intend and
of which we are entirely unaware? We can’t.”
Malcolm Gladwell, author of Blink!,
says: “[Research] suggests that what we think of as free will is largely an
illusion: much of the time, we are simply operating on automatic pilot, and the
way we think and act is a lot more susceptible to outside influences than we
realize.”
I think the neuroscientists have
misread the experimental evidence. These experiments do make us question how we make decisions. We must admit that our
decisions are mostly made
intuitively, not through a conscious, rational process. The decider here is not
the conscious “You” that you think is yourself. But I argue that the decider is
all of you, including your mostly
subconscious processes. Making those decisions depends upon all of yourself, not
just your biological reflexes, but also your culture and your upbringing. You
are not out of the loop; you are the loop.
Furthermore, there are destructive
implications if people believe they are not responsible for their actions.
Experiments show rates of cheating are much lower when subjects read prompts about
being free and responsible. Ideas have consequences. Society is bound by a glue
of trust. Cheating corrodes healthy society. Taking responsibility for our
actions is vital to a healthy
society.
Unitarian Universalists promote the
principle of “a free and responsible search for truth and meaning.” So our shared faith declares that we have free will and are responsible agents.
As for me, I believe that I should
take responsibility for my life, and avoid the victim role, however tempting
that appears. But what if take too much responsibility? I worry about my kids;
was I a bad parent? I cannot go back in time and redo my past choices. But boy, do I want to! I kick myself a
lot for things I’ve done. I should have closed my business when it started
losing money, instead of taking out that home mortgage and losing my business and my house. Woulda, coulda, shoulda;
what a pathetic litany. What I’ve learned is you have to adopt a new story, such as “you were under stress then
and you did what you thought was best at the time.”
In free will, the will is the hard part. Millions of people are trying to lose
weight. According to experts, the starting point is to make a commitment to a
specific goal and a plan. This way, when part
of you wants to eat too much, you can summon another part to overrule, and remind yourself of your commitment.
Positive reinforcement is the most
effective way to change behaviors. That is the basis for the success of Weight
Watchers and Alcoholics Anonymous; the group regularly gives you rewards for
good behavior. It is hard to change your habits, but after time the new habits
get easier, and your new story takes over.
As I see it, a satisfying moral
universe is one in which I am responsible for my actions and their consequences,
while knowing and accepting the limits of my power. The “Serenity Prayer” asks
for:
· the serenity to accept the things I cannot
change,
· courage to change the things I can, and
· The wisdom to know the difference.
I choose actions from my perceived
options. What is fascinating is that some people perceive options that others
do not. Statistics and common sense say if one is raised in poverty, he or she
is much more likely to not finish high school and then remain in poverty. But how
can we explain the exceptions? Some people overcome poverty, study hard and
succeed. Why? Siblings, even twins, can make different choices and experience
very different outcomes. This is proof that our lives are not determined, that
we have free will.
So, given that you have free will and
are responsible for your life, how then will you live?
