73. (i) _The human being has reason and freedom or rationality and liberty, and has these two faculties from the Lord._ Man has a faculty of understanding, which is rationality, and a faculty of thinking, willing, speaking and doing what he understands, which is liberty; and he has these two faculties from the Lord (see the work _Divine Love and Wisdom,_ nn. 264-270, 425, and above, nn. 43, 44). But many doubts may arise about either of the two faculties when thought is given to them; therefore I want to say something at this point just about man's freedom to act according to reason. [2] First, it should be known that all freedom is of love, so much so that love and freedom are one. As love is man's life, freedom is of his life, too. For man's every enjoyment is from some love of his and has no other source, and to act from the enjoyment of one's love is to act in freedom. Enjoyment leads a man as the current bears an object along on a stream. But loves are many, some harmonious, others not; therefore freedoms are many. In general there are three: natural, rational, and spiritual freedom. [3] _Natural freedom_ is man's by heredity. In it he loves only himself and the world: his first life is nothing else. From these two loves, moreover, all evils arise and thus attach to love. Hence to think and will evil is man's natural freedom, and when he has also confirmed evils in himself by reasonings, he does them in freedom according to his reason. Doing them is from his faculty called liberty, and confirming them from his faculty called rationality. [4] For example, it is from the love into which he is born that he desires to commit adultery, to defraud, to blaspheme, to take revenge. Confirming these evils in himself and by this making them allowable, he then, from his love's enjoyment in them, thinks and wills them freely and as if according to reason, and so far as civil laws do not hinder, speaks and does them. It is of the Lord's divine providence that man is allowed to do so, for freedom or liberty is his. This natural freedom is man's by nature because by heredity, and those are in this freedom who have confirmed it in themselves by reasonings from enjoyment in self-love and love of the world.
