Aquinas on Universe, Human Nature, and Happiness
This paper examines three foundational questions posed by Thomas Aquinas in Summa Theologica: the nature of the universe, the nature of man, and how human beings may achieve happiness. Drawing directly from Aquinas's text, the paper traces his five arguments for God as the First Mover, First Cause, and supreme governor of all nature. It then considers his account of human nature — flawed, yet inherently oriented toward a concept of God — and concludes with his view that true happiness, or beatitude, is ultimately found in God rather than in riches or earthly pleasures.

What makes this paper effective
- The paper anchors every claim in direct quotation from the primary source, giving each analytical point textual grounding rather than relying on paraphrase alone.
- It follows a logical progression that mirrors Aquinas's own chain of reasoning — moving from cosmology to anthropology to ethics — which allows the reader to see how the three questions are interconnected.
- Brief but clear explanatory sentences follow each quotation, ensuring the reader understands how the cited passage supports the argument being made.
Key academic technique demonstrated
The paper demonstrates close reading of a primary philosophical text. Rather than summarizing Aquinas in broad terms, the student selects specific passages and unpacks their meaning in context, showing how individual sentences contribute to a larger theological and philosophical framework.
Structure breakdown
The paper is organized around three explicit questions — the nature of the universe, the nature of man, and the conditions for happiness — each treated as a discrete section. This question-and-answer structure keeps the argument focused and makes it easy to follow. The final section on happiness draws together threads from the previous two, giving the paper a modest but coherent arc.
The Nature of the Universe According to Aquinas
According to Thomas Aquinas, the great theologian and author of Summa Theologica, the nature of the universe may be explained through five aspects: motion, an order of efficient causes, necessity and possibility, gradation among things, and governance by an intelligent Almighty.
With respect to motion, the text states, "In the world some things are in motion," and "whatever is in motion is put in motion by another." Aquinas's claim is that for things to be transformed from a state of potentiality to one of actuality, movers are required — with the First and Decisive Mover being God.
Secondly, Aquinas states that "in the world of sense we find there is an order of efficient causes." In other words, all things in the universe are caused by another, with the very first efficient cause being God. Thirdly, the text explains, "We find in nature things that are possible to be and not to be, since they are found to be generated, and to corrupt, and consequently, they are possible to be and not to be." This means that all entities in the universe — with the exception of God — cannot always exist.
With regard to gradation, Aquinas observes that "there are some more and some less good, true, noble and the like." All perfection and goodness in the universe exists to varying degrees among God's creation, with maximum goodness and absolute perfection present in none but the Creator.
Finally, concerning governance, the text explains: "Things which lack intelligence, such as natural bodies, act for an end, and this is evident from their acting always, or nearly always, in the same way, so as to obtain the best result," and that "nature works for a determinate end under the direction of a higher agent." Aquinas implies that an intelligent being — the Almighty — governs the movement of all natural entities toward the specific ends they consistently achieve. The higher agent referred to here is God.
