Excerpts from Bill Gate’s wonderful Harvard commencement, given about two weeks ago. I didn’t post it then, but I’ve been feeling a nagging need to do so, so here it is. The full text can be found here.

I left Harvard with no real awareness of the awful inequities in the world – the appalling disparities of health, and wealth, and opportunity that condemn millions of people to lives of despair.

I learned a lot here at Harvard about new ideas in economics and politics. I got great exposure to the advances being made in the sciences.

But humanity’s greatest advances are not in its discoveries – but in how those discoveries are applied to reduce inequity. Whether through democracy, strong public education, quality health care, or broad economic opportunity – reducing inequity is the highest human achievement.

I left campus knowing little about the millions of young people cheated out of educational opportunities here in this country. And I knew nothing about the millions of people living in unspeakable poverty and disease in developing countries.

It took me decades to find out.

…

We were shocked. We had just assumed that if millions of children were dying and they could be saved, the world would make it a priority to discover and deliver the medicines to save them. But it did not. For under a dollar, there were interventions that could save lives that just weren’t being delivered.

If you believe that every life has equal value, it’s revolting to learn that some lives are seen as worth saving and others are not. We said to ourselves: “This can’t be true. But if it is true, it deserves to be the priority of our giving.”

…

I am optimistic that we can do this, but I talk to skeptics who claim there is no hope. They say: “Inequity has been with us since the beginning, and will be with us till the end – because people just … don’t … care.” I completely disagree.

I believe we have more caring than we know what to do with.

All of us here in this Yard, at one time or another, have seen human tragedies that broke our hearts, and yet we did nothing – not because we didn’t care, but because we didn’t know what to do. If we had known how to help, we would have acted.

…

When you consider what those of us here in this Yard have been given – in talent, privilege, and opportunity – there is almost no limit to what the world has a right to expect from us.

In line with the promise of this age, I want to exhort each of the graduates here to take on an issue – a complex problem, a deep inequity, and become a specialist on it. If you make it the focus of your career, that would be phenomenal. But you don’t have to do that to make an impact. For a few hours every week, you can use the growing power of the Internet to get informed, find others with the same interests, see the barriers, and find ways to cut through them.

Don’t let complexity stop you. Be activists. Take on the big inequities. It will be one of the great experiences of your lives.

…

And I hope you will come back here to Harvard 30 years from now and reflect on what you have done with your talent and your energy. I hope you will judge yourselves not on your professional accomplishments alone, but also on how well you have addressed the world’s deepest inequities … on how well you treated people a world away who have nothing in common with you but their humanity.

Good luck.
