Superstitions, bigotries, affected devotion, prejudices, those forms all forms as they are, are tenacious of life; they have teeth and nails in their smoke, and they must be clasped close, body to body, and war must be made on them, and that without truce; for it is one of the fatalities of humanity to be condemned to eternal combat with phantoms. It is difficult to seize darkness by the throat, and to hurl it to the earth.
