evidence: The writer Isaac Asimov summarizes this point well, "Your assumptions are your windows on the world. Scrub them off every once in awhile, or the light won’t come in." The chemist Albert Szent-Györgyi, who discovered vitamin C, said, "Discovery consists of looking at the same thing as everyone else and thinking something different." The renowned physicist Arthur Eddington more precisely counseled, "The contemplation in natural science of a wider domain than the actual leads to a far better understanding of the actual." All of these legendary thinkers force us beyond our current assumptions and this is the foundation of critical thinking…and genius.
