Not by the very sense and sight indeed—
(Which take at best imperfect cognizance,
Since, how heart moves brain, and how both move hand,
What mortal ever in entirety saw?)
—No dose of purer truth than man digests,
But truth with falsehood, milk that feeds him now,
Not strong meat he may get to bear some day—
To wit, by voices we call evidence,
Uproar in the echo, live fact deadened down,
Talked over, bruited abroad, whispered away,
