How to pronounce "alleged"

["Rebecca Newberger Goldstein"]

["Steven Pinker"]

["The Long Reach of Reason"]

Cabbie: Twenty-two dollars. Steven Pinker: Okay.

Rebecca Newberger Goldstein: Reason appears to have fallen on hard times:

Popular culture plumbs new depths of dumbth

and political discourse has become a race

to the bottom.

We're living in an era of scientific creationism,

9/11 conspiracy theories, psychic hotlines,

and a resurgence of religious fundamentalism.

People who think too well

are often accused of elitism,

and even in the academy,

there are attacks on logocentrism,

the crime of letting logic dominate our thinking.

SP: But is this necessarily a bad thing?

Perhaps reason is overrated.

Many pundits have argued that a good heart

and steadfast moral clarity

are superior to triangulations of overeducated policy wonks,

like the best and brightest and that dragged us

into the quagmire of Vietnam.

And wasn't it reason that gave us the means

to despoil the planet

and threaten our species with weapons of mass destruction?

In this way of thinking, it's character and conscience,

not cold-hearted calculation, that will save us.

Besides, a human being is not a brain on a stick.

My fellow psychologists have shown that we're led

by our bodies and our emotions

and use our puny powers of reason

merely to rationalize our gut feelings after the fact.

RNG: How could a reasoned argument logically entail

the ineffectiveness of reasoned arguments?

Look, you're trying to persuade us of reason's impotence.

You're not threatening us or bribing us,

suggesting that we resolve the issue

with a show of hands or a beauty contest.

By the very act of trying to reason us into your position,

you're conceding reason's potency.

Reason isn't up for grabs here. It can't be.

You show up for that debate

and you've already lost it.

SP: But can reason lead us in directions

that are good or decent or moral?

After all, you pointed out that reason

is just a means to an end,

and the end depends on the reasoner's passions.

Reason can lay out a road map to peace and harmony

if the reasoner wants peace and harmony,

but it can also lay out a road map to conflict and strife

if the reasoner delights in conflict and strife.

Can reason force the reasoner to want

less cruelty and waste?

RNG: All on its own, the answer is no,

but it doesn't take much to switch it to yes.

You need two conditions:

The first is that reasoners all care

about their own well-being.

That's one of the passions that has to be present

in order for reason to go to work,

and it's obviously present in all of us.

We all care passionately

about our own well-being.

The second condition is that reasoners

are members of a community of reasoners

who can affect one another's well-being,

can exchange messages,

and comprehend each other's reasoning.

And that's certainly true of our gregarious

and loquatious species,

well endowed with the instinct for language.

SP: Well, that sounds good in theory,

but has it worked that way in practice?

In particular, can it explain

a momentous historical development

that I spoke about five years ago here at TED?

Namely, we seem to be getting more humane.

Centuries ago, our ancestors would burn cats alive

as a form of popular entertainment.

Knights waged constant war on each other

by trying to kill as many of each other's peasants as possible.

Governments executed people for frivolous reasons,

like stealing a cabbage

or criticizing the royal garden.

The executions were designed to be as prolonged

and as painful as possible, like crucifixion,

disembowelment, breaking on the wheel.

Respectable people kept slaves.

For all our flaws, we have abandoned

these barbaric practices.

RNG: So, do you think it's human nature that's changed?

SP: Not exactly. I think we still harbor instincts

that can erupt in violence,

like greed, tribalism, revenge, dominance, sadism.

But we also have instincts that can steer us away,

like self-control, empathy, a sense of fairness,

what Abraham Lincoln called

the better angels of our nature.

RNG: So if human nature didn't change,

what invigorated those better angels?

SP: Well, among other things,

our circle of empathy expanded.

Years ago, our ancestors would feel the pain

only of their family and people in their village.

But with the expansion of literacy and travel,

people started to sympathize

with wider and wider circles,

the clan, the tribe, the nation, the race,

and perhaps eventually, all of humanity.

RNG: Can hard-headed scientists

really give so much credit to soft-hearted empathy?

SP: They can and do.

Neurophysiologists have found neurons in the brain

that respond to other people's actions

the same way they respond to our own.

Empathy emerges early in life,

perhaps before the age of one.

Books on empathy have become bestsellers,

like "The Empathic Civilization"

and "The Age of Empathy."

RNG: I'm all for empathy. I mean, who isn't?

But all on its own, it's a feeble instrument

for making moral progress.

For one thing, it's innately biased

toward blood relations, babies

and warm, fuzzy animals.

As far as empathy is concerned,

ugly outsiders can go to hell.

And even our best attempts to work up sympathy

for those who are unconnected with us

fall miserably short, a sad truth about human nature

that was pointed out by Adam Smith.

Adam Smith: Let us suppose that the great empire

of China was suddenly swallowed up by an earthquake,

and let us consider how a man of humanity in Europe

would react on receiving intelligence

of this dreadful calamity.

He would, I imagine, first of all express very strongly

his sorrow for the misfortune of that unhappy people.

He would make many melancholy reflections

upon the precariousness of human life,

and when all these humane sentiments

had been once fairly expressed,

he would pursue his business or his pleasure

with the same ease and tranquility

as if no such accident had happened.

If he was to lose his little finger tomorrow,

he would not sleep tonight,

but provided he never saw them,

he would snore with the most profound security

over the ruin of a hundred million of his brethren.

SP: But if empathy wasn't enough to make us more humane,

what else was there?

RNG: Well, you didn't mention what might be

one of our most effective better angels: reason.

Reason has muscle.

It's reason that provides the push to widen

that circle of empathy.

Every one of the humanitarian developments

that you mentioned originated with thinkers

who gave reasons for why some practice

was indefensible.

They demonstrated that the way people treated

some particular group of others

was logically inconsistent

with the way they insisted on being treated themselves.

SP: Are you saying that reason

can actually change people's minds?

Don't people just stick with whatever conviction

serves their interests

or conforms to the culture that they grew up in?

RNG: Here's a fascinating fact about us:

Contradictions bother us,

at least when we're forced to confront them,

which is just another way of saying

that we are susceptible to reason.

And if you look at the history of moral progress,

you can trace a direct pathway from reasoned arguments

to changes in the way that we actually feel.

Time and again, a thinker would lay out an argument

as to why some practice was indefensible,

irrational, inconsistent with values already held.

Their essay would go viral,

get translated into many languages,

get debated at pubs and coffee houses and salons,

and at dinner parties,

and influence leaders, legislators,

popular opinion.

Eventually their conclusions get absorbed

into the common sense of decency,

erasing the tracks of the original argument

that had gotten us there.

Few of us today feel any need to put forth

a rigorous philosophical argument

as to why slavery is wrong

or public hangings or beating children.

By now, these things just feel wrong.

But just those arguments had to be made,

and they were, in centuries past.

SP: Are you saying that people needed

a step-by-step argument to grasp

why something might be a wee bit wrong

with burning heretics at the stake?

RNG: Oh, they did. Here's the French theologian

Sebastian Castellio making the case.

Sebastian Castellio: Calvin says that he's certain,

and other sects say that they are.

Who shall be judge?

If the matter is certain, to whom is it so? To Calvin?

But then, why does he write so many books about manifest truth?

In view of the uncertainty, we must define heretics

simply as one with whom we disagree.

And if then we are going to kill heretics,

the logical outcome will be a war of extermination,

since each is sure of himself.

SP: Or with hideous punishments

like breaking on the wheel?

RNG: The prohibition in our constitution

of cruel and unusual punishments

was a response to a pamphlet circulated in 1764

by the Italian jurist Cesare Beccaria.

Cesare Beccaria: As punishments become more cruel,

the minds of men, which like fluids

always adjust to the level of the objects

that surround them, become hardened,

and after a hundred years of cruel punishments,

breaking on the wheel causes no more fear

than imprisonment previously did.

For a punishment to achieve its objective,

it is only necessary that the harm that it inflicts

outweighs the benefit that derives from the crime,

and into this calculation ought to be factored

the certainty of punishment

and the loss of the good

that the commission of the crime will produce.

Everything beyond this is superfluous,

and therefore tyrannical.

SP: But surely antiwar movements depended

on mass demonstrations

and catchy tunes by folk singers

and wrenching photographs of the human costs of war.

RNG: No doubt, but modern anti-war movements

reach back to a long chain of thinkers

who had argued as to why we ought to mobilize

our emotions against war,

such as the father of modernity, Erasmus.

Erasmus: The advantages derived from peace

diffuse themselves far and wide,

and reach great numbers,

while in war, if anything turns out happily,

the advantage redounds only to a few,

and those unworthy of reaping it.

One man's safety is owing to the destruction of another.

One man's prize is derived from the plunder of another.

The cause of rejoicings made by one side

is to the other a cause of mourning.

Whatever is unfortunate in war,

is severely so indeed,

and whatever, on the contrary,

is called good fortune,

is a savage and a cruel good fortune,

an ungenerous happiness deriving its existence from another's woe.

SP: But everyone knows that the movement

to abolish slavery depended on faith and emotion.

It was a movement spearheaded by the Quakers,

and it only became popular when Harriet Beecher Stowe's novel

"Uncle Tom's Cabin" became a bestseller.

RNG: But the ball got rolling a century before.

John Locke bucked the tide of millennia

that had regarded the practice as perfectly natural.

He argued that it was inconsistent

with the principles of rational government.

John Locke: Freedom of men under government

is to have a standing rule to live by

common to everyone of that society

and made by the legislative power erected in it,

a liberty to follow my own will in all things

where that rule prescribes not,

not to be subject to the inconstant,

uncertain, unknown, arbitrary will of another man,

as freedom of nature is to be under no other restraint

but the law of nature.

SP: Those words sound familiar.

Where have I read them before? Ah, yes.

Mary Astell: If absolute sovereignty be not necessary

in a state, how comes it to be so in a family?

Or if in a family, why not in a state?

Since no reason can be alleged for the one

that will not hold more strongly for the other,

if all men are born free,

how is it that all women are born slaves,

as they must be if being subjected

to the inconstant, uncertain,

unknown, arbitrary will of men

be the perfect condition of slavery?

RNG: That sort of co-option

is all in the job description of reason.

One movement for the expansion of rights

inspires another because the logic is the same,

and once that's hammered home,

it becomes increasingly uncomfortable

to ignore the inconsistency.

In the 1960s, the Civil Rights Movement

inspired the movements for women's rights,

children's rights, gay rights and even animal rights.

But fully two centuries before,

the Enlightenment thinker Jeremy Bentham

had exposed the indefensibility

of customary practices such as

the cruelty to animals.

Jeremy Bentham: The question is not, can they reason,

nor can they talk, but can they suffer?

RNG: And the persecution of homosexuals.

JB: As to any primary mischief,

it's evident that it produces no pain in anyone.

On the contrary, it produces pleasure.

The partners are both willing.

If either of them be unwilling,

the act is an offense,

totally different in its nature of effects.

It's a personal injury. It's a kind of rape.

As to the any danger exclusive of pain,

the danger, if any, much consist

in the tendency of the example.

But what is the tendency of this example?

To dispose others to engage in the same practices.

But this practice produces not pain of any kind

to anyone.

SP: Still, in every case, it took at least a century

for the arguments of these great thinkers

to trickle down and infiltrate the population as a whole.

It kind of makes you wonder about our own time.

Are there practices that we engage in

where the arguments against them are there for all to see

but nonetheless we persist in them?

RNG: When our great grandchildren look back at us,

will they be as appalled by some of our practices

as we are by our slave-owning, heretic-burning,

wife-beating, gay-bashing ancestors?

SP: I'm sure everyone here could think of an example.

RNG: I opt for the mistreatment of animals

in factory farms.

SP: The imprisonment of nonviolent drug offenders

and the toleration of rape in our nation's prisons.

RNG: Scrimping on donations to life-saving charities

in the developing world.

SP: The possession of nuclear weapons.

RNG: The appeal to religion to justify

the otherwise unjustifiable,

such as the ban on contraception.

SP: What about religious faith in general?

RNG: Eh, I'm not holding my breath.

SP: Still, I have become convinced

that reason is a better angel

that deserves the greatest credit

for the moral progress our species has enjoyed

and that holds out the greatest hope

for continuing moral progress in the future.

RNG: And if, our friends,

you detect a flaw in this argument,

just remember you'll be depending on reason

to point it out.

Thank you. SP: Thank you.

(Applause)
