Be not so set upon poetry, as to be always poring on the passionate and measured pages. Let not what should be sauce, rather than food for you, engross all your application. Beware of a boundless and sickly appetite for the reading of poems which the nation now swarms withal; and let not the Circaen cup intoxicate you. But especially preserve the chastity of your soul from the dangers you may incur, by a conversation with muses no better than harlots.
