Haste me to know it, that I with wings as swift
As meditation or the thoughts of love
May sweep to my revenge.

– William Shakespeare

Hamlet, Act 1, Scene 5. Hamlet urges the Ghost to reveal the identify of his father’s murderer, so that he can summon up the rage to seek revenge. Revenge doesn’t come naturally to a cautious and reticent Hamlet, when he talks of "meditation" and "thoughts of love" (for his father) in the same breath.
