" It is wise to have decisions of great moment monitored by generalists. Experts and specialists lead you quickly into chaos. They are a source of useless nit-picking, the ferocious quibble over a comma. The mentat-generalist, on the other hand, should bring to decision-making a healthy common sense. He must not cut himself off from the broad sweep of what is happening in his universe. He must remain capable of saying: “There’s no real mystery about this at the moment. This is what we want now. It may prove wrong later, but we’ll correct that when we come to it. "

― Frank Herbert , Children of Dune (Dune, #3)
