Video Summary
AI GeneratedThis video explores the evolution of human rights, tracing the path from Enlightenment ideals and the U.S. Declaration of Independence to the creation of the Universal Declaration of Human Rights (UDHR) following the atrocities of the 20th century. It examines the tension between these idealistic global standards and the reality of their enforcement.
We hold these truths to be self-evident,
that all men are created equal,
that they are endowed by their creator
with certain unalienable rights,
that among these are life, liberty,
and the pursuit of happiness.
This is an excerpt of the U.S. Declaration of Independence.
And the United States goes on with its Constitution,
which gets ratified in 1789,
to articulate a Bill of Rights.
And many will point to the Enlightenment
as the inspiration for these ideas.
Thomas Jefferson, who wrote the Declaration of Independence,
cited figures like Locke as some of mankind's best thinkers.
So at this early date,
nations were at least writing these types of words
into their Declarations of Independence,
into their Constitutions.
But despite that, the 20th century
is one of the bloodiest centuries in human history.
You have World War I, where roughly 17 million people die.
In World War II, 50 to 80 million people die,
some directly because of the conflict,
but many because of lack of access to food and famine.
The Chinese are particularly hit.
Over 15 million die during the Japanese occupation of China.
This idea of genocide comes about.
First, with the Armenian Genocide
in the declining Ottoman Empire,
where over a million people are believed to have been killed.
And then in World War II, you have the Holocaust,
where six to 11 million people were killed,
roughly 2 3rds of the Jewish population in Europe
and many others.
The Russian Empire and eventually the Soviet Union
gets especially hit hard
in the first half of the 20th century.
In World War I alone, three million Russians die.
Shortly after the war,
you have a significant Russian famine
that killed five million people.
Then in the early 30s, you have the Soviet famine,
five to seven million people.
This is believed to have occurred
because of Stalin's attempts
to make agriculture collectivized.
In the late 30s, you have Stalin's purge,
where he goes after political opponents,
and it's believed that he killed
as many as three million people.
These things were so shocking to the planet
that they made attempts to prevent them in the future.
In 1920, out of the trauma of World War I,
the League of Nations was founded.
It was an attempt to prevent things like this in the future,
for nations to talk to each other and to coordinate
so they don't go to war,
especially at the scale seen in World War I.
But clearly that was unsuccessful,
and we have World War II, where even more people die,
after which the slightly stronger United Nations
gets founded, once again with the charter
of fostering dialogue between nations
so that we can prevent these types of trauma for the planet.
Early on in the newly founded UN agenda
was this idea of revisiting the ideas of the Enlightenment,
this idea of human rights,
and trying to codify them in international law.
In 1948, you have the Universal Declaration of Human Rights
that's drafted by the United Nations,
and it was an attempt to make a universal declaration
of these rights that all humans on the planet
have access to.
I'm going to give excerpts of it,
and keep a lookout for things that feel awfully close
to ideas in the United States Declaration of Independence,
the US Constitution, or ideas from the Enlightenment.
This is part of the preamble.
Whereas recognition of the inherent dignity
and of the equal and inalienable rights
of all members of the human family
is the foundation of freedom, justice,
and peace in the world.
Whereas disregard and contempt for human rights
have resulted in barbarous acts
which have outraged the conscience of mankind.
Remember, World War II just happened.
And the advent of a world in which human beings
shall enjoy freedom of speech and belief
and freedom from fear and want
has been proclaimed as the highest aspiration
of the common people.
Now, therefore, the General Assembly proclaims
this Universal Declaration of Human Rights
as a common standard of achievement
for all peoples and all nations.
You might be thinking,
why do they even have to write this?
Well, think about it.
Things like the constitutions of various countries,
especially the United States,
these only applied to those countries.
But now there was an attempt to write down,
to codify something that would apply to all human beings,
to the entire planet.
And here's just some of the 30 articles to that declaration,
to that Universal Declaration of Human Rights.
All human beings are born free
and equal in dignity and rights.
They are endowed with reason and conscience
and should act towards one another
in a spirit of brotherhood.
This really feels similar to some of the ideas of Locke
in the Enlightenment that we talk about in other videos.
Everyone is entitled to all the rights and freedoms
set forth in this declaration
without distinction of any kind,
such as race, color, sex, language, religion,
political, or other opinion, national or social origin,
property, birth, or other status.
So this is interesting because even though
I start this video with the United States
Declaration of Independence
and discussion of the Constitution,
slavery in the United States would last
for another 80 plus years
after the Declaration of Independence was written.
Women didn't even have the right to vote
until the early 20th century.
So beyond this being a universal declaration,
for the entire planet, the attempt is also
to make it clear that it needs to apply to everyone.
Everyone has the right to life,
liberty, and security of person.
No one shall be held in slavery or servitude.
No one shall be subjected to torture
or to cruel, inhuman, or degrading treatment or punishment.
Everyone charged with a penal offense
has the right to be presumed innocent
until proved guilty.
Once again, ideas that seem very similar
to what we see in constitutions
like that of the United States.
Everyone has the right to freedom of thought,
conscience, and religion.
Everyone has the right to freedom of opinion and expression,
very similar to the First Amendment in the US Constitution.
Everyone has the right to freedom
of peaceful assembly and association.
No one may be compelled to belong to an association.
And Article 21 is especially interesting.
Everyone has the right to take part
in the government of his country
directly or through freely chosen representatives.
Everyone has the right of equal access
to public service in his country.
The will of the people shall be the basis
of the authority of government.
So this is a big statement.
It's taking a stand, saying that everyone on the planet
should be able to live in a democracy
and participate in a democracy.
The commission that drafted this declaration
was chaired by Eleanor Roosevelt,
wife of Franklin Roosevelt.
This is a map of who voted for this declaration,
and these are the countries in green.
Who abstained, they just decided not to vote
for the declaration, those are the countries in orange.
And then you have a few that voted against it.
In gray are the countries that weren't part
of the United Nations at the time.
An interesting question, looking at this map,
is to think about why certain countries
were willing to vote for it
and why other countries decided to abstain at the time.
These articles are talking about people
having the right to participate in a democracy,
the right to be equal, that all people are equal.
And in many of these countries,
people did not have equal rights.
You had severe discrimination in places like South Africa.
In many of these countries, you did not have a democracy.
But there's a broader question here.
It's nice to be able to write these fairly idealistic ideas,
but to what degree does it have an effect?
And to what degree can it actually be enforced?
You might cite things like
the American Civil Rights Movement,
which did echo some of these ideas
that were made in the Universal Declaration of Human Rights.
Maybe they helped the Civil Rights Movement,
or maybe the Civil Rights Movement would have happened
regardless of what the UN did.
But at the same time, you have ideas like apartheid.
You had racism and discrimination in South Africa
from the beginning of colonial rule,
but it was actually at the exact same time
as this declaration that the official policy of apartheid,
of government-sanctioned discrimination,
of government-sanctioned segregation,
preventing racial mingling, came into effect
and lasted all the way until 1991.
And so one could make an argument,
maybe things would have been worse
without the Universal Declaration of Human Rights,
or maybe the Universal Declaration of Human Rights
really wasn't in a situation
to actually affect things like this.
In many of the countries around the world,
not just the orange ones,
but often in many of the green ones as well,
you continued to see things that go against
those ideas of universal human rights.
Even if the UN passes something
and if one country doesn't want to abide by it,
what action can the other countries take?
Economic action, maybe sanctions, maybe military action,
and to what degree are people actually willing to do that?
