Final answer:
Duke Orsino considers men to be more swayed by passion than women, as implicitly stated in lines 4-6 from Act II, Scene IV of Shakespeare's 'Twelfth Night,' where he admits that men's fancies are 'giddy and unfirm,' 'longing, wavering,' and 'sooner lost and won.'
Step-by-step explanation:
The set of lines that shows Duke Orsino considers men to be more easily swayed by passion than women is from William Shakespeare's Twelfth Night, Act II, Scene IV, lines 4-6:
'For, boy, however we do praise ourselves, our fancies are more
giddy and unfirm
, more
longing, wavering
, sooner
lost and won
, than women's are.'
This excerpt directly depicts Orsino's belief that men have fancies which are less constant and more susceptible to change than those of women, highlighting a stereotype of the time about the nature of male passion.
