Understanding Thomas Aquinas Through His Words
Thomas Aquinas was a medieval philosopher and Dominican theologian whose writings brought Christian teaching into conversation with Aristotle’s philosophy. His work belongs within the wider history explored in our collection of the greatest philosophers of all time, where questions about knowledge and the good life take many forms.
Aquinas often builds an argument by considering objections before presenting his answer. A sentence found in his books may express a position he rejects or quote an earlier writer.
The selections below identify those distinctions where needed. English wording also varies between translations, so each attribution names the translation or source used, while brackets mark capitalization changes in excerpts.
Thomas Aquinas Quotes on Faith and Prayer
1. Faith Gives Reason a Place
“Since therefore grace does not destroy nature but perfects it, natural reason should minister to faith as the natural bent of the will ministers to charity.”Thomas Aquinas, Summa Theologiae, Part I, question 1, article 8, reply to objection 2. Translated by the Fathers of the English Dominican Province, 1920.
For Aquinas, faith leaves meaningful work for the human mind. Reason can examine questions, clarify ideas, and help us understand what we believe, even when some truths lie beyond what reason can establish alone.
The word “perfects” carries the thought forward. Grace brings human nature toward its fulfillment, including our ability to think, rather than asking us to abandon that ability. His own practice of patiently working through objections gives this conviction a practical form.
2. A Prayer for a Faithful Life
“Grant me, O Lord my God, a mind to know you, a heart to seek you, wisdom to find you, conduct pleasing to you, faithful perseverance in waiting for you, and a hope of finally embracing you.”Thomas Aquinas, prayer excerpt quoted by Pope Benedict XVI on June 16, 2010.
The movement of this prayer is especially tender. Knowing God leads toward seeking him, living faithfully, and continuing to hope through the long work of waiting.
It also brings thought and conduct together. Understanding has a place beside the way we treat people and the choices we make when no answer comes quickly. Benedict XVI included the prayer in his reflection on Aquinas’s faith and thought.
3. What We Believe Shapes How We Live
“Three things are necessary for the salvation of man: to know what he ought to believe, to know what he ought to desire, and to know what he ought to do.”Thomas Aquinas, Explanation of the Ten Commandments, prologue. English wording reproduced by the Thomistic Institute.
Aquinas connects these three forms of knowledge with the Creed, the Lord’s Prayer, and the commandments. Each addresses a different part of Christian life, bringing belief into conversation with desire and action.
Desire deserves particular attention here. Our lives take shape around what we want, which means spiritual growth includes learning what is worth wanting in the first place.
Thomas Aquinas Quotes on Wisdom and the Search for Truth
4. The Joy of Pursuing Wisdom
“Of all human pursuits, the pursuit of wisdom is the more perfect, the more sublime, the more useful, and the more agreeable.”Thomas Aquinas, Summa contra Gentiles, Book I, chapter 2. Joseph Rickaby’s English rendering, Of God and His Creatures.
The warmth of “agreeable” may surprise readers who expect philosophy to be a joyless task. Aquinas sees pleasure in the pursuit itself, because growing in wisdom already allows us some share in the happiness we seek.
His meaning is deeply religious: wisdom draws us toward God. Yet the delight of understanding offers an approachable starting point, whether we are reading a difficult book or finally grasping a question that has troubled us.
5. Philosophy Seeks What Is True
“[T]he study of philosophy aims not at knowing what men feel, but at what is the truth of things.”Thomas Aquinas, Commentary on Aristotle’s De Caelo, Book I, lecture 22. Translated by Fabian R. Larcher and Pierre H. Conway. Excerpt.
In this passage, Aquinas considers how earlier philosophers should be understood. Establishing what they meant matters, but the inquiry must eventually reach the truth of the subject itself.
That distinction gives reading a deeper purpose. We can learn the history of an argument while still asking whether its reasoning deserves our trust.
6. Respect Can Survive Disagreement
“[W]e must respect both parties, namely, those whose opinion we follow, and those whose opinion we reject.”Thomas Aquinas, Commentary on Aristotle’s Metaphysics, Book XII, lesson 9, explaining Aristotle’s discussion. Excerpt.
Respecting a person does not require accepting their conclusion. Aquinas explains that people on opposing sides may both contribute to the search for truth, even though we must follow the position supported with greater certainty.
This is a generous approach to disagreement because it gives another person’s effort its due. Someone can help us think more carefully by raising an objection, exposing a weakness, or asking a question we would otherwise have missed.
7. Understanding Is Worth Sharing
“For even as it is better to enlighten than merely to shine, so is it better to give to others the fruits of one’s contemplation than merely to contemplate.”Thomas Aquinas, Summa Theologiae, Part II–II, question 188, article 6, main answer. Translated by the Fathers of the English Dominican Province, 1920.
Aquinas is discussing teaching and preaching that grow from contemplation. The image of light captures how something carefully understood can become a gift to someone else.
A patient teacher offers a familiar example. Their knowledge takes on another kind of value when they find the explanation that helps a struggling student understand.
8. Deep Understanding Takes Work
“Thus, only with great labour of study is it possible to arrive at the searching out of the aforesaid truth; and this labour few are willing to undergo for sheer love of knowledge.”Thomas Aquinas, Summa contra Gentiles, Book I, chapter 4. Joseph Rickaby’s English rendering, Of God and His Creatures.
The truth under discussion is knowledge of God reached through reason, which Aquinas believes requires extensive preparation. He recognizes that such study takes time and effort that many people cannot give.
The surrounding passage also acknowledges the demands of work and daily responsibilities. That context keeps the quotation from becoming a careless judgment of people with little leisure, while preserving its respect for the patience serious inquiry requires.
Thomas Aquinas Quotes on Love and Friendship
9. Friendship Deserves a Place of Honor
“First of all, among all worldly things there is nothing which seems worthy to be preferred to friendship.”Thomas Aquinas, De Regno (On Kingship), Book I, chapter 11. Translated by Gerald B. Phelan, revised by I. Th. Eschmann.
This passage appears in a work about kingship, where Aquinas considers the rewards of just rule. Even in a discussion of political power, friendship holds a place that wealth and authority cannot easily fill.
Its value is also recognizable in ordinary life. A friend knows something of our history, shares our pleasures, and makes difficult days less lonely through the simple fact of being there.
10. Love Wishes Another Person Well
“As the Philosopher says (Rhet. ii, 4), ‘to love is to wish good to someone.”Thomas Aquinas, Summa Theologiae, Part I–II, question 26, article 4. Translated by the Fathers of the English Dominican Province, 1920.
“The Philosopher” here means Aristotle, whose definition Aquinas uses to examine different forms of love. The attribution matters, as does the distinction that follows.
Loving someone involves concern for their good. It asks us to consider what would help them flourish, even when that differs from what would make our own lives easier.
11. Love Can Reach Beyond Friendship
“Indeed, so much do we love our friends, that for their sake we love all who belong to them, even if they hurt or hate us; so that, in this way, the friendship of charity extends even to our enemies, whom we love out of charity in relation to God, to Whom the friendship of charity is chiefly directed.”Thomas Aquinas, Summa Theologiae, Part II–II, question 23, article 1, reply to objection 2. Translated by the Fathers of the English Dominican Province, 1920.
Aquinas begins with a familiar experience: affection for a friend can extend to the people connected with them. He then uses that relationship to explain the Christian call to love one’s enemies through love of God.
Here, “charity” means a form of love, not simply a donation. The passage asks us to consider whether another person’s good can still matter to us when affection is difficult or absent.
Thomas Aquinas Quotes on Sorrow and Comfort
12. Grief Needs Room for Expression
“This is why men, burdened with sorrow, make outward show of their sorrow, by tears or groans or even by words, their sorrow is assuaged.”Thomas Aquinas, Summa Theologiae, Part I–II, question 38, article 2. Translated by the Fathers of the English Dominican Province, 1920.
“Assuaged” means eased, and that modest word suits the experience of grief. Speaking about a loss or allowing ourselves to cry may bring some relief without changing what has happened.
Aquinas gives emotional expression a reasonable place in human life. His account offers reassurance to anyone who has mistaken tears for a failure to cope.
13. A Friend Can Help Carry Sorrow
“When one is in pain, it is natural that the sympathy of a friend should afford consolation: whereof the Philosopher indicates a twofold reason (Ethic. ix, 11).”Thomas Aquinas, Summa Theologiae, Part I–II, question 38, article 3. Translated by the Fathers of the English Dominican Province, 1920.
Aquinas goes on to compare sorrow with a weight that feels lighter when someone helps bear it. A friend’s sympathy offers the comfort of knowing that another person recognizes what we are carrying.
This helps explain why presence can matter more than a perfect sentence. Sitting with someone, listening without rushing them, or remembering an important date can give their grief a little company.
Thomas Aquinas Quotes on Judgment and the Common Good
14. Immediate Pleasure Is Not Our Only Good
“[M]ore men seek good in regard to the senses than good according to reason.”Thomas Aquinas, Summa Theologiae, Part I, question 49, article 3. Translated by the Fathers of the English Dominican Province, 1920. Excerpt.
Aquinas distinguishes what appeals to us immediately from what reason recognizes as good for a human life. The senses have their proper place, but their attractions do not settle every question about how we should act.
We encounter that tension whenever a satisfying reaction would leave lasting damage. Pausing before sending an angry message gives judgment time to consider more than the pleasure of having the final word.
15. Law Should Serve the Community
“Therefore every law is ordained to the common good.”Thomas Aquinas, Summa Theologiae, Part I–II, question 90, article 2. Translated by the Fathers of the English Dominican Province, 1920.
Aquinas is describing the purpose that gives law its proper character. This is a standard for judging laws, rather than an assurance that everything a government enacts is just.
The common good asks us to look beyond private advantage. A community needs conditions in which people can live well together, and those who exercise authority carry responsibility for that shared life.
Carrying These Ideas Into Daily Life
These Thomas Aquinas quotes connect the work of understanding with the choices that shape a life. Seeking truth calls for patience, friendship asks for care, and faith reaches into both what we desire and how we act.
We do not have to master every argument to begin thinking alongside him. A worthwhile beginning may be to listen more fairly, give a friend our full attention, or pursue a difficult question with greater honesty. Wisdom becomes part of our lives through the care we bring to such moments.
