William Shakespeare, Troilus and Cressida

"Pleasure and revenge have ears more deaf than adders to the voice of any true decision."

"He eats nothing but doves, love, and that breeds hot blood, and hot blood beget hot thoughts, and hot thoughts beget hot deeds, and hot deeds is love."

"For to be wise and love exceeds man's might."

"Modest doubt is call'd the beacon of the wise."

"Cressida: My lord, will you be true?Troilus: Who, I? Alas, it is my vice, my fault:Whiles others fish with craft for great opinion,I with great truth catch mere simplicity;Whilst some with cunning gild their copper crowns,With truth and plainness I do wear mine bare. Fear not my truth: the moral of my wit Is "plain and true"; there's all the reach of it."
