BEROWNE.
Come on, then; I will swear to study so,
To know the thing I am forbid to know,
As thus: to study where I well may dine,
When I to feast expressly am forbid;
Or study where to meet some mistress fine,
When mistresses from common sense are hid;
Or, having sworn too hard-a-keeping oath,
Study to break it, and not break my troth.
If study's gain be thus, and this be so,
Study knows that which yet it doth not know.
Swear me to this, and I will ne'er say no.

KING.
These be the stops that hinder study quite,
And train our intellects to vain delight.

BEROWNE.
Why, all delights are vain; but that most vain
Which, with pain purchas'd, doth inherit pain:
As painfully to pore upon a book,
To seek the light of truth; while truth the while
Doth falsely blind the eyesight of his look.
Light, seeking light, doth light of light beguile;
So, ere you find where light in darkness lies,
Your light grows dark by losing of your eyes.
Study me how to please the eye indeed,
By fixing it upon a fairer eye;
Who dazzling so, that eye shall be his heed,
And give him light that it was blinded by.
