If thou remember'st not the slightest folly,
That ever love did make thee run into,
Thou hast not loved.

As you like it, Shakespeare.

Portrait by John Faed, 1819-1902.

He uses his folly like a stalking-horse, and under the presentation of that he shoots his wit.

As you like it, Shakespeare.

But love is blind, and lovers cannot see
The pretty follies that themselves commit.

The Merchant of Venice [II. vi. 36]
Shakespeare.

But love is blind and lovers cannot see
The pretty follies that themselves commit;
For if they could, Cupid himself would blush
To see me thus transformed to a boy.

William Shakespeare (1564 - 1616), The Merchant of Venice, Act II Scene 6
