I have tried to understand how viruses work, how viruses think, how the immune system works and other questions that pertain to my interests, whether it was cancer or immune disease, or multiple sclerosis, and now AIDS. But I am also interested in the human side of these issues. Why do I see things differently from the way other people see them? Why do I pursue the questions that I pursue, even if others regard them as, as they say, “controversial?” Which merely means that they have a difference of opinion. They see things differently. I am interested both in nature and in the human side of nature, and how the two can be brought together, and effective in a useful way.
