I believe in intuition and inspiration. At times I feel certain I am right while not knowing the reason. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
Another quote proving my point about the word evolution denoting change over time. Here Einstein is using "evolution" as a synonym for progress. Nothing Darwinian or even biological is intended.
