This final course in the History of Ideas sequence brings students fully into the modern world. Beginning with an investigation of the value and purpose of an education, the course delves into the philosophical underpinnings of what an education is and the role it plays as a cornerstone for fostering liberty, critical thinking, and democratic engagement. Through the works of Newman, Dewey, Hutchins, Hayek, and Miłosz, this course not only examines the theoretical aspects of education but also considers its practical implications for cultivating informed and free individuals. Turning to the topic of psychology, the course follows the modern history of the study of the human mind, tracing the evolution of psychological inquiry from William James' foundational principles to Freud's psychoanalytical theories and Jung's concepts of the collective unconscious. Students then move to the topic of modern literature and the shifts in literary expression that mirror the tumultuous changes of the 20th century. Through an examination of Joyce, Woolf, Eliot, and others, students engage with the themes of consciousness, time, memory, and the search for meaning in a fragmented world. This part of the course highlights the ways in which modernist writers broke with traditional narrative forms and content, reflecting the broader societal shifts and the internal dynamics of individuals navigating the complexities of modern life. Finally, students gain an introduction to the realm of modern mathematics and physics, and the groundbreaking discoveries and theories that reshaped our understanding of the universe, from non-Euclidean geometry, to relativity, to quantum mechanics. This course captures the dynamic interplay between empirical research and theoretical innovation, offering students insights into the profound transformations in our conceptualization of space, time, matter, and the very nature of reality.
