Scientists, and doctors, are people like everybody else. And just as religious institutions have been corrupted to the interests of wars and genocide, scientists are corrupted by politics, pride and avarice to suppress good science. But in my opinion, the search for the truth cannot know such bounds. One must take the search for truth wherever it leads. If I can't stand the answer, I shouldn't ask the question in the first place.
Lack of imagination is as much a limiting factor in science and discovery as lack of technology is.
In other words, it is easier to discover what is when one can imagine what might be . In this respect, Linus Pauling was one of the best examples of a modern-age scientist. His curiosity and imagination led him to explore many diverse fields of science, many in which he demonstrated excellence. Not only is he the only person to win two unshared Nobel prizes, he might well have won a third for discovering the structure of DNA if the US government had not prevented him from attending a scientific meeting in Europe where key crystallographic data on DNA were presented. Pauling had most of the structure worked out and only needed a few additional pieces of information to put it all together.
