Trivial Pursuit

Okay, time for a little bit of trivia. The only thing you need to do is be the first to answer the question of who authored the following quote.

"Human blood is no cement for the temple of liberty."

_ a _ _ _ l

_'_ _ n _ _ _ l

(All guesses should be placed in the comments section.)

P.S. I filled in a couple of letters, I hope it helps.

* They'll never figure it out, mwahahahahaha . Wait, you weren't supposed to hear that!*
