From a website covering the topic of logical argumentative essays.
"Example One": Even though there may be a deceiver of some sort, very powerful and very tricky, who bends all his efforts to keep me perpetually deceived, there can be no slightest doubt that I exist, since he deceives me; and let him deceive me as much as he will, he can never make me be nothing as long as I think I am something. Thus, after having thought well on this matter, and after examining all things with care, I must finally conclude and maintain that this proposition: I am, I exist, is necessarily true every time that I pronounce it or conceive it in my mind. - Rene Descartes
Translation:"I am a blithering idiot".
Do what thy manhood bids thee do, from none but self expect applause; He noblest lives and noblest dies who makes and keeps his self-made laws. -Sir Richard Francis Burton
