I'm a bit bemused by your question, but anyway:

'Perhaps the easiest way to epitomize the differences between these two groups is to contrast the way they use the phrase "I see." When visionaries say "I see," they do so with their eyes closed. That's how visionaries see. Pragmatists, on the other hand, like to see with their eyes open. They don't trust visionaries for the same reasons that they don't trust people who want to navigate using the force.' - Moore, Geoffrey A. Inside the Tornado (1995) p. 19
