The Thomistic Institute

Fr. Thomas Davenport argues against the Thomist intuition that artifice obscures nature, showing from Aquinas's account of art and artifacts that artificial forms are accidental forms rooted in the natural active and passive powers of substances, so that scientific instruments and experiments reveal rather than distort the natures they investigate.

This lecture was given on July 18th, 2026, at Dominican House of Studies.

Dr. Sarah E. Maple asks how we acquire an organic vision of beauty that is not merely material or visual, arguing from Aquinas's formal criteria of beauty (proportion, integrity, clarity) and Hans Urs von Balthasar's theological aesthetics (form and splendor, beholding and enrapture) that beauty belongs first to the human person, and that the artist's vocation is grounded in wonder, self-gift, and the sincerity of the body, culminating in a spirituality of artistic service.

This lecture was given on April 21st, 2026, at University of Georgia.

Fr. Gabriel Torretta argues that beauty has become a "forbidden word" for our age due to the effects of German Idealism and Modernism; as a remedy, he proposes a recovery grounded in the Christian metaphysical tradition (Eriugena, Aquinas, Augustine), in which beauty is the attractive power by which God draws all things to himself and which requires an asceticism of the gaze.

This lecture was given on April 28th, 2026, at University of Washington.

Fr. Alan O'Sullivan provides an introduction to Pope Benedict XVI's thought on the "via pulchritudinis" — the way of beauty — arguing that authentic beauty wounds the heart and draws it toward the transcendent Logos, is inseparable from truth, goodness, and prayer, and is indispensable for the Church's liturgy and evangelization against a false, self-absorbing beauty.

This lecture was given on July 18th, 2026, at Glencomeragh House.

Fr. Irenaeus Dunlevy argues that the Exodus prohibition on graven images was a purification of Israel's imagination from false imaginings of the invisible God, and that the Incarnation opens a new, positive use of sacred images — the face of Christ and the icons of his saints — by which the imagination is fed and purified for contemplation, a truth vindicated by Saint John Damascene and the Second Council of Nicaea against the iconoclasts.

Fr. Irenaeus Dunlevy argues that church architecture is "incarnational" when it corresponds to a true cosmological vision of reality ordered through and toward the Logos and embodies the principles revealed to Moses on Sinai, and "iconoclastic" when, in its modernist self-referentiality, it rejects that order and fails to communicate the body and head of Christ made present in the liturgy.

Fr. David Goodill explains that, for Aquinas, conscience is not a power of the soul but an act of the intellect rooted in the natural habit of synderesis and formed by the virtues, above all prudence, so that it reflects the deepest interiority of the person.

Fr. David Goodill expounds Aquinas's treatment of conscience in Summa theologiae I-II, q.19, arguing that conscience is the inner act of the will and that, even when erring, it binds the agent, such that right formation of conscience through virtue, law, and grace is essential.

Prof. Lewis Ayres presents Newman's account of conscience as, not a private inner voice, but the echo of God's voice within the human being, that although refracted by sin and therefore requiring long formation in humility and obedience, is an entry into true fraternity.
