@maxdancona,
Einstein is an interesting example of reason and intuition.
Einstein's great successes started with a great idea. He explored a couple of very important thoughts (with relativity and the photoelectric effect) that no one else had taken. This was great creativity and can be called intuition.
But, of course, Einstein's successful work was completely well-reasoned. He worked out the math... every point. He understood experimental work and previous theories and made sure that his results matched.
And Einstein published well-reasoned papers. Every step was documented with rigorous math. Every point of his reasoning can be understood by other scientists and questioned (and it was).
Einsteins greatest failure was his inability to accept Quantum Mechanics. This, ironically, is a field of science based on his work on the Photoelectric effect.
But when other men reasoned further, Einstein balked based on his intuition. His famous line objecting to Quantum Physics was "God does not play dice with the Universe".
Of course, in this case, Einstein was wrong.
