Einstein famously said:
Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.
In answer to the question, “Do you trust more to your imagination than to your knowledge?” From interview with G. S. Viereck, “What Life Means to Einstein,” Saturday Evening Post, October 26, 1929; reprinted in Viereck, Glimpses of the Great, 447

Is Einstein's opinion what Kant would also hold?
Aristotle, St. Thomas, et el. say that the intellect is superior to the will with its "imagination," "phantasms," or "sense images". Aristotle said the human intellect is in a way everything because it can potentially understand anything. This "intellect" seems to be what Einstein calls "imagination" in his quote.
Does saying imagination is more important than knowledge mean that Einstein held Scotus's view that the will is primary and the intellect secondary, subjected to the will?
Have any philosophers specifically treated imagination vs. knowledge?
