The line from Act 3, Scene 5, where Capulet tentatively offers Paris his daughter's hand contradicts this line:
A. But will her, gentle Paris, gets her heart; / my will to her consent is but a part. / And, she agreed, within her scope of choice / lies my consent and fair according voice.
In this earlier statement, Capulet emphasizes that his consent is only part of the equation and that Juliet's own choice and feelings are paramount. This is directly at odds with his later assertion that he believes Juliet will be "ruled" by him, suggesting that he expects to have complete control over her decision to marry Paris.
