To me, when I was offered the chair, this was a major... a major problem – should I accept and therefore, sort of, bow down to this authority in some ways, or should I go elsewhere and be free? And, well, family reasons intervened; by that time I had two children, a wife of course, and especially our families... especially my wife's family were very much attached to the children and so on. And so moving away would have been a very traumatic experience for the whole family and so, more or less reluctantly, very reluctantly, I decided that I would accept. Professionally I can't complain because, I mean, the work that has made me known in the field of science was done at the Catholic University of Louvain so, obviously, they did not interfere with my freedom as a scientist and I remain grateful to them; they supported me whenever it was possible. And so the problem, for me, was simply that being a member of the faculty at the Catholic University of Louvain, I felt that my loyalty to the institution demanded that I should not publicly speak on religious matters. And so I kept... I kept that attitude for almost the whole of my life until very recently. Although, of course, my friends knew. And probably many of the university knew that I wasn't a very strong believer, but I never made a gesture, if I may say so.
