Gaudium et Spes §55

⁵⁵ From day to day, in every group or nation, there is an increase in the number of men and women who are conscious that they themselves are the authors and the artisans of the culture of their community. Throughout the whole world there is a mounting increase in the sense of autonomy as well as of responsibility. This is of paramount importance for the spiritual and moral maturity of the human race. This becomes more clear if we consider the unification of the world and the duty which is imposed upon us, that we build a better world based upon truth and justice. Thus we are witnesses of the birth of a new humanism, one in which man is defined first of all by this responsibility to his brothers and to history.
