We need a flow of wild ideas, though some will drift ever onward, into the vast nowhere: beyond application or reason. One will catch on the shore, others will pile into it, becoming a beaver dam of bad ideas. Unstable? Maybe. But the flood will rise, and lift that stuck idea, and send the whole logjam spiraling out to the deeps where maybe one idea will float apart, and find the light that makes it look worth chasing.
