The intuitive mind is a sacred gift, and the rational mind is a faithful servant. We have created a society that honors the servant and has forgotten the gift -Albert Einstein.
Based on the quote above clearly Einstein valued his intuition and used his thinking and intellect to apply it. There are many stories of Einstein having intuitions and dreams that informed him. One was how he came to the Theory of Relativity.
At the early age of 16, he had an amazing thought. It was
” a paradox upon which I had already hit at the age of sixteen: If I pursue a beam of light with the velocity c (velocity of light in a vacuum), I should observe such a beam of light as an electromagnetic field at rest though spatially oscillating. There seems to be no such thing, however, neither on the basis of experience nor according to Maxwell’s equations. From the very beginning, it appeared to me intuitively clear that, judged from the standpoint of such an observer; everything would have to happen according to the same laws as for an observer who, relative to the earth, was at rest. For how should the first observer know or be able to determine, that he is in a state of fast uniform motion?” (www.pitt.edu)
