Nowdays it is sometimes held, though wrongly, that freedom is an end in itself, that each human being is free when he makes use of freedom as he wishes, and that this must be our aim in the lives of individuals and societies. In reality, freedom is a great gift only when we know how to use it consciously for everything that is our true good.
-Redemptor Hominis
Freedom negates and destroys itself, and becomes a factor leading to the destruction of others, when it no longer recognizes and respects its essential link with the truth. When freedom, out of a desire to emancipate itself from all forms of tradition and authority, shuts out even the most obvious evidence of an objective and universal truth… then the person ends up by no longer taking as the sole and indisputable point of reference for his own choices the truth about good and evil, but only his subjective and changeable opinion or, indeed, his selfish interest and whim.
