"True conformity to the dictates of nature requires reverence for the past and solicitude for the future. 'Nature' is not simply the sensation of the passing moment; it is eternal, though we evanescent men experience only a fragment of it. We have no right to imperil the happiness of posterity by impudently tinkering with the heritage of humanity."
"Every right is married to a duty, every freedom owns a corresponding responsibility. There cannot be genuine freedom unless there exists also genuine order in the moral realm and in the social realm."
