Poesy must not be drawn by the ears: it must be gently led, or rather, it must lead, which was partly the cause that made the ancient learned affirm it was a divine, and no human skill, since all other knowledges lie ready for any that have strength of wit; a poet no industry can make, if his own genius be not carried into it.
