Instruments of Knowledge: The Role of Objects in Science

The Thomistic Philosophy and Natural Science Symposium gathers expert scientists and philosophers to discuss the potential compatibility and mutual enrichment of the study of Aquinas’ philosophy of nature and various forms of modern scientific knowledge in mathematics, physics, chemistry, and biology.

How do we define a “scientific instrument,” and what exactly is a scientist doing when they use a scientific instrument? This year’s symposium will explore the role of objects in the sciences. We will hear from scientists who use instruments to extend or exteriorize human competencies and senses, allowing them to perceive the very far or the very small. We will consider what St. Thomas says (or does not say) about the role of objects in knowing, and contemplate whether instrument readings or human sense perceptions are to be preferred in the production of knowledge.

Cost, Location, and Accommodation:

All registration costs, food, lodging, and activities are covered by the Thomistic Institute.

This year’s symposium will once again be held in Washington, D.C. Attendees will stay in lodging near the Dominican House of Studies. Lectures and meals will all be on site. Opportunities for Mass, Eucharistic Adoration, and Liturgy of the Hours will be available with the Dominican Friars.

Applications should be submitted by June 1, 2026.
