"many look forward to a genuine and total emancipation of humanity wrought solely by human effort"

"Thinking they have found serenity in an interpretation of reality everywhere proposed these days, many look forward to a genuine and total emancipation of humanity wrought solely by human effort; they are convinced that the future rule of man over the earth will satisfy every desire of his heart. Nor are there lacking men who despair of any meaning to life and praise the boldness of those who think that human existence is devoid of any inherent significance and strive to confer a total meaning on it by their own ingenuity alone."

- Pope Paul VI, Gaudium et Spes
