According to American writer and editor H.L. Mencken, "Conscience is the inner voice which warns us someone may be looking." A person who is conscientious makes sure that if others are watching, they like what they see. "Conscience" and "conscientious" both come from the Latin verb "conscire," a word that means "to be conscious" or "to be conscious of guilt" and that traces back to a still older Latin word, "scire," meaning "to know."
