Now, this ideology gets policed by this one very dangerous question, which is, "What percentage of my donation goes to the cause versus overhead?" There are a lot of problems with this question. I'm going to just focus on two. First, it makes us think that overhead is a negative, that it is somehow not part of the cause. But it absolutely is, especially if it's being used for growth.

You see, researchers have coined this term "color blindness" to describe a learned behavior where we pretend that we don't notice race. If you happen to be surrounded by a bunch of people who look like you, that's purely accidental. Now, color blindness, in my view, doesn't mean that there's no racial discrimination, and there's fairness. It doesn't mean that at all. It doesn't ensure it. In my view, color blindness is very dangerous because it means we're ignoring the problem.

I will start by stating the obvious. No one here questions whether development is desirable. No one questions the inherent need to save lives and help others by giving. However, I believe that we need to rethink the ways in which we help others. We need to give from the perspective of empowering the recipient, instead of making them dependent on us.

The next generation of telescopes will see millions of events per night with computers that sift through huge amounts of data. If we had had access to a computer, we would never have programmed it to look for something so unexpected. How do you pick up the things you don't know exist, the things you can't tell it to look for? My project was to study quasars, and then we accidentally stumble over these things called pulsars. They were totally unexpected, totally unknown – and it's been huge fun.

Tolerance ought only to be a preliminary step which allows us to get to know other people, and which prevents us from setting up bars, just because they may be of a different race or religion. The real value of any relationship is the fact that we learn to like people in spite of our differences.

If silence seems to give approval, then remaining silent is cowardly.

Courage is more exhilarating than fear and in the long run it is easier. We do not have to become heroes overnight. Just a step at time, meeting each thing that comes up, seeing it is not as dreadful as it appeared, discovering we have the strength to stare it down.
