Faustus is gone. Regard his hellish fall,

Whose fiendful fortune may exhort the wise

Only to wonder at unlawful things,

Whose deepness doth entice such forward wits,

To practise more than heavenly power permits.

—Christopher Marlowe, Dr. Faustus

Remember

First to possess his books, for without them

He’s but a sot, as I am, nor hath not

One spirit to command: they all do hate him

As rootedly as I. Burn but his books.

—William Shakespeare, The Tempest
