When my first son was born I was surprised and impressed by his attitude. As I remember it, just a few moments old, with his entire fist in his mouth, he stared intently at the bright heat lamp above him. I occurred to me that he hadn’t known vision until this moment. He had never seen light before.
Five years later it was the morning of his first day of
first grade. Off to school. When I went into his room to rouse him he was
sitting bolt upright, hugely excited. He
took a deep breath and exhaled two words …J
”What’s next??!” J
I’m thinking now of how great an attitude this is, this wonderment, this “what’s
next.” I also know that the attitude can dampen as one slowly takes on
responsibilities, and learns more about struggle, discomfort, and disappointment. You can’t be wide-eyed all your life – but there
actually is an adult version of “what’s next??!”, I think. And it’s a certain sort of optimism.
I’ve had the pleasure recently of reading several books that
recommend optimism. One is Steven Pinker’s
The Better Angels of our Nature, which demonstrates that violence has declined
dramatically, in almost every way, almost everywhere, at every time scale, and for
reasons that also have much broader implications for human well-being. Matt Ridley’s The Rational Optimist explains
how commerce, specialization, technology, communication, and democracy bring about
wonderful things, ingenious solutions, and the promise of much more. And philosopher David Deutsch’s The Beginning
of Infinity – a dense book -- explores the nature of knowledge, and discusses
optimism itself in a way that was new to me.
For one thing, he explained that philosophical optimism and
philosophical pessimism are much alike.
The former is the view that the world is just as good as it could
possibly be, and the latter, that it could get no worse. Neither leaves room for rational explanation
of why things are so. In modern terms,
on the other hand, the words optimism and pessimism are directed only toward the future, where
“blind optimism” manifests as overconfidence or recklessness while pessimism
justifies what is known as the “precautionary principle:” avoid everything not already
known to be safe.
I’m attempting to condense a very dense train of thought
into a short commentary, but through history, Deutsch says, most societies were
pessimistic, i.e., intolerant, conformist, and precautionary. Bad leaders were retained because “better the
devil you know than the devil you don’t know.”
Non-conventional behavior was considered immoral.
Tradition, ritual, and laws were designed to keep things as they were. A small event was expected to have potentially large, unforeseen, and negative consequences (e.g., “a
butterfly flaps its wings in Brazil and it causes a hurricane in Texas”). Creative, "different," ideas were quashed by social institutions and, worse, the creative spirit itself was muted. So there was not only little tolerance for change, there was little threat of change as well. Blindly optimistic societies, on the other
hand, were less common, as they often suffered the harsh consequences of recklessness.
Deutsch defines his preferred version of optimism much the
same, I think, as Matt Ridley … and I’ll use Ridley’s adjective to distinguish
it from the philosophical of blind versions: it’s rational optimism. At its core is this idea: “All
evils are caused by insufficient knowledge.” Problems are inevitable, in
other words. And they are soluble.
By accepting that things are imperfect we expect that
problems will arise. The problems, from
a rationally optimistic perspective, have solutions, and solutions come from
knowledge. Hence, knowledge will lead to solutions, problems are solved, and there is progress. And this next point really turns me on: The
key is that, because the solutions themselves are imperfect, finding the right
solution is a mostly a matter of identifying and discarding those that don’t work.
Karl Popper applied this principle to political philosophy
around 1950. How can we rid ourselves of
bad governments without violence, he had asked.
Deutsch paraphrases Popper's answer: “Systems of government are to be judged
not for their prophetic ability to choose and install good leaders and policies,
but for their ability to remove bad ones that are already there.” It’s simply trial and error, ironically (for
an optimist) the emphasis is on the detection of error.
This seems to me very much
like Darwin’s natural selection, 100 years earlier. Accepting that creatures are imperfectly
suited for their environment (inherently improvable), progress occurs not by
designing a perfect organism but by experimentation and selective removal of the errors. But if natural selection
is “optimistic” it’s optimistic in a way that is decidedly not anthropomorphic. From our perspective, for an example, malaria is a problem – from the disease’s perspective, humans are a solution.
Rational optimism is forward reaching, and it was the rationally optimistic who develop
vaccines, lightbulbs, and computers. Pessimists thought
it couldn't -- and shouldn't -- be done because they hadn't faith in rational thought. To them, there is a catastrophe right around the corner (They live to 90, though, because of the rational optimism of others).
Either of these systems – optimism or pessimism – has a self-sustaining
feedback loop. The first takes on more
and more complex problems by embracing them one after the other, attempting solutions, and then better and better solutions to more nuanced problems. The pessimists are locked in a steady state; problems are obstacles for which knowledge will never be a match, so why bother trying? With this attitude, knowledge isn't created, which becomes a self-fulfilling prophesy and a justification for more pessimism itself.
I had been thinking that optimism and pessimism were just counterparts -- cup half empty, or cup half full. But Deutsch helped me see there is a huge difference
between these perspectives. The number
of potential futures for an optimist is infinite, it moves forward, carefully, into an uncertain future. The pessimist is afraid to do that. The difference is not half full/half empty, it's the difference between infinity and the number 1.
So – full circle -- how does one retain a J “What’s next” J attitude toward
life? Expect problems, try to solve
them, and be prepared to learn from the trying.
But if a five-year-old ever asks me that
question again (one can hope) I think I’ll just say “don’t know yet … let’s see!
