Compendium of the Social Doctrine of the Church

Openness to transcendence belongs to the human person: man is open to the infinite and to all created beings. He is open above all to the infinite — God — because with his intellect and will he raises himself above all the created order and above himself, he becomes independent from creatures, is free in relation to created things and tends towards total truth and the absolute good. He is open also to others, to the men and women of the world, because only insofar as he understands himself in reference to a “thou” can he say “I”. He comes out of himself, from the self-centred preservation of his own life, to enter into a relationship of dialogue and communion with others. The human person is open to the fullness of being, to the unlimited horizon of being. He has in himself the ability to transcend the individual particular objects that he knows, thanks effectively to his openness to unlimited being. In a certain sense the human soul is — because of its cognitive dimension — all things: “all immaterial things enjoy a certain infiniteness, insofar as they embrace everything, or because it is a question of the essence of a spiritual reality that functions as a model and likeness of everything, as is the case with God, or because it has a likeness to everything or is ‘in act' like the Angels or ‘in potential' like souls”^{245Saint Thomas Aquinas, Commentum in tertium librum Sententiarum, d. 27, q. 1, a. 4: “Ex utraque autem parte res immateriales infinitatem habent quodammodo, quia sunt quodammodo omnia, sive inquantum essentia rei immaterialis est exemplar et similitudo omnium, sicut in Deo accidit, sive quia habet similitudinem omnium vel actu vel potentia, sicut accidit in Angelis et animabus”; cf. Saint Thomas Aquinas, Summa Theologiae, I, q. 75, a. 5: Ed. Leon. 5, 201-203.}.
