Mark Zuckerberg holds first Facebook Community Summit in Chicago

"I believe the most important thing we can do is work to bring people closer together. It's so important that we're changing Facebook's whole mission to take this on. For the past decade, we've focused on making the world more open and connected. We're not done yet and we will continue working to give people a voice and help people connect. But even as we make progress, our society is still divided. So now I believe we have a responsibility to do even more. It's not enough to simply connect the world; we must also work to bring the world closer together.

We need to give people a voice to get a diversity of opinions out there, but we also need to build enough common ground so we can all make progress together. We need to stay connected with people we already know and care about, but we also need to meet new people with new perspectives. We need support from family and friends, but we also need to build communities to support us as well.

Our new mission will continue our path and set our course for the next decade.

The idea for our mission is: "bring the world closer together".

The full mission statement is: "give people the power to build community and bring the world closer together". This reflects that we will not accomplish this mission ourselves, but by empowering people around the world to build communities and bring people together.

Our lives are all connected. In the next generation, our greatest opportunities and challenges we can only take on together -- ending poverty, curing diseases, stopping climate change, spreading freedom and tolerance, stopping violence. No single group or even nation can do them alone.

This isn't going to happen top down. Change starts local, when enough of us feel a sense of purpose and support in our own lives that we can start caring about broader issues too.

Communities give us that sense that we are part of something greater than ourselves, that we are not alone, and that we have something better ahead to work for.

This is our challenge. We have to build a world where every single person has a sense of purpose and community. That's how we'll bring the world closer together.

A mission isn't just a statement. It's a nuanced philosophy and hope for the world. We carry out our mission not through repeating a statement, but in the work each of us do every day. And if enough of us work to build community and bring people together, then we just might change the world.

Thank you for all you do for your communities and for the world. It's an honor to be on this mission with you, and I'm looking forward to doing this together", Zuckerberg said.
