"I put my cup down and examine my own mind.  It is for it to discover the truth.  But how?  What an abyss of uncertainty whenever the mind feels that some part of it has strayed beyond its own borders; when it, the seeker, is at once the dark region through which it must go seeking, where all its equipment will avail it nothing.  Seek? More that 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 Proust, In Search of Lost Time Vol. 1: Swann's Way
