so I sometimes think, why should I talk young women into being a scientist if they then end up being sort of disliked or not accepted by their contemporaries and so it’s a tricky business actually.

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.

The most important piece of advice that I could give them is to take advantage of the tremendous reservoir of knowledge that’s out there today. Spend some time learning how the world has evolved. There are a lot of good lessons in history, and other peoples’ experiences in the past, that could be exactly the solution to the problem you’re looking for.

Having advanced well beyond what the French call "a certain age," I am often asked to convey to younger people helpful advice and counsel. So I will open these remarks with the best advice I ever received. The advice, which I have several times shared with others, was given to me by my mother-in-law on my wedding day. She had a prescription for a happy, enduring marriage: "It pays," she said, "it pays sometimes to be a little deaf."

But one of the things that my father did was to let me read comics. Now people used to say that’s bad because it isn’t — it spoils your English but, in fact, letting me read — I devoured all kinds of comics — fed my love for English and my love for reading but I suppose if he had been firm I might not have developed this deep love for reading and for English, which stood me in good stead when I later went into hospital for 20 months. I did have something to do. I had — as things maybe got a little bit more serious, I was given a diet — we didn’t have too many books but my father was keen that one read things like Aesop’s Fables and Lamb’s, Tales from Shakespeare . I didn’t read the originals but I read these stories that describe what Shakespeare was saying in the plays and that possibly was something that sharpened your appetite for later.

I know that for a very long time my consuming passion, which was confirmed when I contracted TB — I had TB when I was about 12 or so — was I wanted to be a physician and when I got TB I was even more determined. I want to be physician so that I can find a cure for the scourge. And, in fact, I was admitted to medical school. If we had had the funds maybe today I would have been a physician.

I sent off the letter. I probably made a technical mistake by giving it to a journalist before hearing from the Prime Minister because this journalist was working for a Sunday newspaper and gave it enormous press, and I think quite rightly the Prime Minister was annoyed that I had not given him the opportunity but never mind.

And actually now having had the advantage of the Truth and Reconciliation Commission and being able to look at some of the records of what the apartheid government was doing, the thing that is surprising to me is why so many of us survived. I mean, how is it that they did not assassinate more of us?

What is rewarding about the priesthood is, one, that you have an incredible privilege of being privy to some of the most extraordinary things about people. I mean, as their parish priest, you visit people who are sick, say, on their death bed and they tell you things that they probably have not shared with any other person. You are privileged to bring the Holy Sacrament to people at a time when they are probably at their lowest. But you also have the privilege of meeting up with people at their moment of great joy, when they are getting married, or when they have a child baptized.

I used to be “Mister Disinvestment.” Now I would like to be Mister Investment and say, “Come! Come and be part of an exciting, exhilarating process. Come in! Come in on the ground floor and see a people do something that’s probably never happened before, people seeking to become something radically different from what their antecedents would have made us believe they were likely to become.
