The word which is best said came nearest to not being spoken at all, for it is cousin to a deed which the speaker could have better done. Nay, almost it must have taken the place of a deed by some urgent necessity, even by some misfortune, so that the truest writer will be some captive knight, after all. And perhaps the fates had such a design, when, having stored Raleigh so richly with the substance of life and experience, they made him a fast prisoner, and compelled him to make his words his deeds, and transfer to his expression the emphasis and sincerity of his action.

— Henry David Thoreau
