Thomas Nagel teaching Ethics

He has dedicated his career to studying ethics, political philosophy, and the philosophy of mind. His work often examines the tension between objective facts and subjective experiences. Nagel has held many important academic positions throughout his life. He taught at the University of California, Berkeley, from 1963 to 1966. He then spent fourteen years at Princeton University, from 1966 to 1980. Finally, he served as a professor at New York University from 1980 until 2016. His deep inquiries into the nature of thought continue to influence how we view the relationship between the mind and the physical world.

Nagel's philosophical method involves analyzing how humans attempt to build a unified worldview. He observes that humans instinctively seek a single, consistent way to understand everything. However, he argues that such a unified view is impossible for finite, limited creatures. We often encounter different ways of understanding that cannot be perfectly reconciled. Nagel specifically looks at the distinction between objective and subjective perspectives. He notes that modern science provides a highly objective way of seeing the world. This scientific view uses mathematics to describe the physical universe. It focuses on things like mass and shape, which are called primary qualities. These qualities exist independently of how any specific person perceives them.

Despite his respect for science, Nagel identifies a significant limitation in the scientific method. He argues that science often relies on a "view from nowhere." This is an attempt to describe the world without any personal perspective. While this works for studying physical objects, Nagel believes it fails when applied to the mind. The mind is inherently subjective, meaning it always has a point of view. He suggests that by trying to be perfectly objective, science might leave out something essential. It may describe the physical brain but miss the actual experience of being a thinker. This creates a gap between the physical processes we can measure and the internal lives we actually lead.

One of Nagel's most influential contributions is his 1974 essay, "What Is It Like to Be a Bat?" In this work, he explores the concept of the "subjective character" of consciousness. He proposes that an organism has conscious mental states if there is something that it is like to be that organism. For example, science can explain the biology and sonar of a bat. However, science cannot capture the internal, subjective experience of being a bat. This concept challenges "physicalism," the idea that everything can be explained by physical processes alone. Nagel argues that consciousness has an irreducible subjectivity. This means that the feeling of an experience cannot be fully captured by describing physical parts like neurons or chemicals.

Nagel's ideas have sparked intense debate among many different types of philosophers. Some critics argue that he is a "dualist." A dualist is someone who believes the mind and body are two different kinds of things. However, Nagel suggests his position is more about the limits of our concepts. He notes that we can only understand mental states by being directly acquainted with them. We cannot learn what a feeling is just by looking at a physical map of the brain. He also discusses the "explanatory gap," which is the difficulty of connecting physical facts to mental feelings. This gap is made harder by how our imagination works. We can imagine physical cells moving, or we can imagine a feeling of pain, but we struggle to connect them perfectly.

Throughout his career, Nagel has received many prestigious honors for his intellectual achievements. In 2008, he was awarded the Rolf Schock Prize for his philosophical work. He also received the Balzan Prize, which is a major international award. His academic standing is reflected in his memberships in several elite organizations. He is a fellow of the American Academy of Arts and Sciences. He is also a corresponding fellow of the British Academy. Additionally, he was elected as a member of the American Philosophical Society in 2006. These honors recognize his lifelong commitment to solving some of the most difficult questions in human thought.

Nagel remains a rationalist, meaning he believes that human reason is a powerful tool. He does not believe that the mystery of the mind is unsolvable. Instead, he suggests that we may need a revolution in our scientific understanding. He hopes for a future science that can bridge the gap between the mental and the physical. He believes a new way of thinking could show how these two aspects are connected. Currently, the mental and the physical seem like separate things. Nagel views this not as a permanent truth, but as a sign of our current stage of knowledge. He anticipates that a more complete understanding of nature will eventually include both the physical world and the subjective mind.
