I believe in clear-cut positions. I think that the most arrogant position is this apparent, multidisciplinary modesty of "what I am saying now is not unconditional, it is just a hypothesis," and so on. It really is a most arrogant position. I think that the only way to be honest and expose yourself to criticism is to state clearly and dogmatically where you are. You must take the risk and have a position.
There is so much more information about the scientific world than there was a generation ago that we have all increased our opportunities for ignorance. There are more things not to know. . . . The machinery that we deal with is so much more complex that it is possible to become dysfunctional at a much higher level of performance.
