From Proust

"But how? What an abyss of uncertainty whenever the mind feels that some part of it has strayed beyond its own borders; whenever it, the seeker, is at once the dark region through which it must go seeking, where all its equipment will avail nothing. Seek? More than that: create. It is face to face with something which does not so far exist, to which it alone can give reality and substance, which it alone can bring into the light of day."" --Marcel, Swann's Way
