"I hop'd therefore, as I said, to have seen you, and unravel'd to you that which lying in the Lump unexplicated in my Mind, I scarce yet know what it is my self; for I have often had Experience that a Man cannot well judge of his own Notions, till either by setting them down in Paper, or in discoursing them to a Friend, he has drawn them out, and as it were spread them fairly before, himself."
— Locke, John (1632-1704)
