In William Shakespeare’s play Twelfth Night, the Duke presents men as fickle and contradictory. For example, in the beginning of the play, the Duke says,
If music be the food of love, play on,
Give me excess of it, that, surfeiting.
The appetite may sicken and so die.
That strain again, it had a dying fall;
O, it came o’er my ear like the sweet sound
That breathes upon a bank of violets,
Stealing and giving odor. Enough, no more;
‘Tis not so sweet now as it was before. (I.i.1-8)
At first the Duke invites the musicians to play. He asks for more and more: “Give me excess of it.” Then, a couple lines later, he is begging them to stop playing. He says, “Enough, no more”. Within the first eight lines of the play, the Duke cannot make up his mind. He reveals his character as indecisive and inconsistent.
Then, in Act two, scene four, the Duke explains how a woman’s love is superficial, but a man’s love is very deep:
There is no woman’s sides
Can bide the beating of so strong a passion
As love doth give my heart; no woman’s heart
So big to hold so much; they lack retention.
Alas, their love may be called appetite,
No motion of the liver but the palate,
That suffers surfeit, cloyment, and revolt;
But mine is all as hungry as the sea
And can digest as much. Make no compare
Between that love a woman can bear me
And I that I owe Olivia. (II.iv.93-103)
With that said, the audience can see how arrogant the Duke’s claim is – that a man’s love is far more profound than that of a woman. With Viola’s character, Shakespeare proves the Duke to be a contradictory man. While the Duke thinks Viola is a man, Viola is completely in love with him. From the beginning of the play, to the end of the play, her love is unwavering. The Duke on the other hand goes from loving Olivia to, at the drop of a hat, loving Viola.
