Vroomfondel and Majikthise maintain that the search for ultimate truth is 'the inalienable prerogative of your working thinkers' (Majikthise), demand rigidly defined areas of doubt and uncertainty (Vroomfondel), and consequently insist that Deep Thought be shut down. At one point Vroomfondel (in an agitated state) even demands that his name may, or may not be Vroomfondel, and has to be corrected that he doesn't need to demand "an absence of solid facts" for everything. However, Deep Thought persuades the philosophers that they can 'keep themselves on the gravy train for life' by arguing in public about what answer the computer will eventually give.
