Three women were brought to the Singapore General Hospital, each in the same condition and needing a blood transfusion. The first, a Southeast Asian was given the transfusion but died a few hours later. The second, a South Asian was also given a transfusion but died a few days later. The third, an East Asian, was given a transfusion and survived. That is the X factor in development.

At the end of the day, what I cherish most are the human relationships. With the unfailing support of my wife and partner I have lived my life to the fullest. It is the friendships I made and the close family ties I nurtured that have provided me with that sense of satisfaction at a life well lived, and have made me what I am.

Now if democracy will not work for the Russians, a white Christian people, can we assume that it will naturally work with Asians?

What I fear is complacency. When things always become better, people tend to want more for less work.

Singaporeans, if I can chose an analogy, we are the hard disk of a computer, the foreign talent are the megabytes you add to your storage capacity. So your computer never hangs because you got enormous storage capacity.

If, for instance, you put in a Malay officer who's very religious and who has family ties in Malaysia in charge of a machine gun unit, that's a very tricky business. We've got to know his background... I'm saying these things because they are real, and if I don't think that, and I think even if today the Prime Minister doesn't think carefully about this, we could have a tragedy.

I started off believing all men were equal. I now know that's the most unlikely thing ever to have been, because millions of years have passed over evolution, people have scattered across the face of this earth, been isolated from each other, developed independently, had different intermixtures between races, peoples, climates, soils... I didn't start off with that knowledge. But by observation, reading, watching, arguing, asking, that is the conclusion I've come to.
