I think Einstein meant something like 'imagination'.
-Science without imagination is lame, imagination without science is blind.-
Some of the things he said/wrote, explain this.
*I am enough of the artist to draw freely upon my imagination. Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world*
*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.*
