" On its own, being a decent person is no guarantee that you will act well, which brings us back to the one protection we have against demagogues, tricksters, and the madness of crowds, and our surest guide through the uncertain shoals of life: clear and reasoned thinking. Logic will never fail you, unless you’re unaware of—or deliberately ignore—the consequences of your deeds. "

― Christopher Paolini , Eragon, Eldest & Brisingr (Inheritance, #1-3)
