It is our nature to want to share who we are and what we do.
Sharing is a basic instinct, a part of our human legacy.

The force of this drive is so enormous that it pervades our lives and shapes
our society and culture.

Sharing probably evolved as a form of bonding in which social ties were
strengthened as a means of protecting the young.
It also served as a mutual benefit to the community.
The instinct to share our thoughts and desires with others perhaps led to
socialized attitudes of empathy, sympathy, and even altruism.

The instinct to share thoughts, feelings, and actions with others may produce
lifelong bonds, offspring, and a shared sense of community.

But it may also be the cause of deep division.

Today, we are no longer hunter-gatherers scattered in small communities. Six
billion people reside on the planet, many of whom are cramped into
densely populated areas.
As the population has increased, individuals have converged geographically who
are different enough from one another that sharing has not occurred
naturally.
People from different origins and different cultures have massed together to
form large and disparate communities.

The deep desire to share with others is frustrated by these differences, and often
results in provoked tensions based on fear, anger, or ignorance.
And when the divisions are wide and deep enough, they may lead to exclusion,
provocation, and war.
The same is true around the world for individuals, small groups, neighborhoods,
towns, cities, and nations.

As we celebrate the diversity of life, we seek a collective bond among people,
while at the same time bemoaning the artifacts of aggression, ignorance,
and divisiveness.

By our social nature, we support and define a deep contradiction of human
evolution.
