How does Donne use paradox in the poem, To Sir Henry Wotton?

Traditionally seen as a refuge from bustling city life, the country in "To Sir Henry Wotton" is no such idyllic place. Instead, Donne argues that the country is a "desert" in which one will find themselves "frozen." This paradox of hot and cold ultimately helps reinforce Donne's argument that extremes of any nature are dangerous, and that neutrality and privacy are crucial in maintaining one's safety and integrity at court.
