This is the entire text of Viola's speech.
"I left no ring with her: what means this lady?
Fortune forbid my outside have not charm'd her!
She made good view of me, indeed so much,
That methought her eyes had lost her tongue,
For she did speak in starts distractedly.
She loves me, sure; the cunning of her passion
Invites me in this churlish messenger.
None of my lord's ring? Why he sent her none.
I am the man: if it be so, as 'tis,
Poor lady, she were better love a dream.
Disguise, I see thou art a wickedness,
Wherein the pregnant enemy does much.
How easy is it for the proper false
In women's waxen hearts to set their forms!
Alas,O frailtie is the cause, not we,
For such as we are made if such we be."
quoted from First Folio
