So much for the research, but now we have to go back again to 1968. 1968 is a sort of watershed in the history of academic life in the world. It started in Berkeley and it continued all over the world... Paris, there was a sort of a revolution by the students who claimed more... a greater say in academic matters, who revolted... rebelled against the sort of supercilious superiority of dons and other academic persons; the... they didn't accept the authority of the professors the way we used to in Germany – the Geheimrat, everybody bowed in front of them. Especially they... they clamoured for more meaningful, more socially-involved science. They wanted science to be more involved with the real problems of the world. And, at that time, I myself... before that time, I had been basically... basically is not the word to use... I had been a major proponent of basic research, strictly pure... so-called pure research. I had learned this from my chief, the physiology professor, Bouckaert: science... the purpose... and the only important purpose of science is to increase knowledge, is to promote our understanding of the world around us, and that's enough, and that is the main goal of science – it's part of culture, increasing our understanding of the world is the only valid purpose for research, and let the public pay for it. I was, at that time, really rather negatively disposed toward any sort of applied research, even medical research. I felt, well, it's my duty to make discoveries; they discover lysosomes and let the medical people worry about what are the possible medical applications. Let the pharmaceutical industry take care of the possible new drugs or therapeutic means that could possibly emerge from this new knowledge; my purpose is to just advance knowledge and let the others dirty their hands with doing something useful.
