In a 1929 interview with Albert Einstein, journalist George Sylvester Viereck asked, "How do you account for your discoveries? Through intuition or inspiration?"
Albert Einstein replied:
"Both. I sometimes feel I am right, but do not know it. When two expeditions of scientists went to test my theory I was convinced they would confirm my theory. I wasn't surprised when the results confirmed my intuition, but I would have been surprised had I been wrong. I'm enough of an artist to draw freely on my imagination, which I think is more important than knowledge. Knowledge is limited. Imagination encircles the world."
