Audio recording of a lecture given by Tutor Emeritus Phil LeCuyer on September 5, 2025 as part of the Dean’s Lecture & Concert Series. The Dean’s Office has provided this description of the event: "In this lecture arrays are contrasted to sequences as paradigms of thought. Sequences are based on causation. What are arrays based on? Several examples of arrays will be considered, including the human face. When viewed and understood as an array, what can a face tell us about being human?"
