Pope Leo XIII attempted a Thomistic revival, particularly with his 1879 encyclical "Aeterni Patris" and his establishment of the Leonine Commission, established to produce critical editions of Aquinas' "opera omnia". This encyclical served as the impetus for the rise of Neothomism, which brought an emphasis on the ethical parts of Thomism, as well as a large part of its views on life, humans, and theology, are found in the various schools of Neothomism. Neothomism held sway as the dominant philosophy of the Roman Catholic Church until the Second Vatican Council, which seemed to confirm the significance of Ressourcement theology. Thomism remains a school of philosophy today, and influential in Catholicism, though "The Church has no philosophy of her own nor does she canonize any one particular philosophy in preference to others."
