Of this hard world.

(Richard 2, Act V, Sc. 5.)

King Henry: “He hath a tear for pity and a hand

Open as day for melting charity:

Yet notwithstanding, being incens’d, he’s flint.

(Henry IV, Part 2, Act IV, Sc. 4.)

Othello: “The tyrant custom, most grave senators,

Hath made the flinty and steel couch of war

My thrice-driven bed of down.

(Othello, Act I, Sc. 3.)
