We are sinful not only because we have eaten of the Tree of Knowledge, but also because we have not yet eaten of the Tree of Life. The state in which we are is sinful, irrespective of guilt.
I had rather be a Kitten, and cry mew, Than one of these same Meeter Ballad-mongers: I had rather heare a Brazen Candlestick turn'd, Or a dry Wheele grate on the Axle-tree, And that would set my teeth nothing an edge, Nothing so much, as mincing Poetrie.
