Abstract

In Gaudium et Spes and Dignitatis Humanae the Second Vatican Council not only presents the dignity of the human person as the parting point for its moral teaching but also grounds human dignity in natural teleology. Natural teleology is the view that the good of any thing corresponds to, and so can be discerned from, the ends to which it is directed by its nature, both that end which is proper to it and those ends that it has as part of a wider order. As official Church teachings, these documents refrain from providing a philosophical justification of their account of human dignity. The existence of natural teleology, however, is generally contested in modern philosophy. For this reason, grounding human dignity in natural teleology constitutes a questionable approach to the issue. Of all major Catholic theologians, Thomas Aquinas is arguably the one who provides the most developed philosophical resources for articulating these views on natural teleology and its connection with human dignity. This paper examines and assesses the way in which he grounds human dignity in natural teleology. In his view, we see that human beings are the principle part of the universe and that the other parts of the universe are ordered towards the good of human beings. After surveying his general justification of how a thing is ordered to particular ends in virtue of its nature, the paper considers his explanation of how each part of the universe assumes further ends within the universe as a whole, and his main set of arguments on how we perceive human dignity against the backdrop of the natural teleology of the universe.
