Self

philosophy religion Maturity 9-11 Next article →

In philosophy, the "self" refers to an individual's unique being, knowledge, and values. It also involves the relationships between these specific attributes. Philosophers often distinguish selfhood from personal identity. While identity refers to literal sameness, selfhood implies a first-person perspective. This perspective suggests a sense of uniqueness. A "person" is often used as a third-person reference to describe someone. Understanding the self is vital because it touches on how we experience existence. It also explores the boundary between the self and "others." This distinction is a major research topic in many fields. These include philosophy, psychology, psychiatry, neurology, and neuroscience.

Psychology offers several ways to model the self. One early modern formulation comes from William James. He divided the self into two distinct elements: the "I" and the "me." The "I" is the subjective knower who experiences the world. The "me" is the subject that is actually known. Modern psychology views the self as essential to human motivation and cognition. It also plays a role in social identity and affect. Some researchers follow the ideas of John Locke. They view the self as a product of episodic memory. However, studies of people with amnesia show a different side. Even without some memories, people maintain a coherent sense of self. This suggests that conceptual autobiographical knowledge can preserve selfhood.

Other psychological traditions offer deeper, more complex views. Carl Jung, a famous figure in analytic psychology, had a unique perspective. He believed the self was not just a center, but a whole circumference. This circumference embraces both the conscious and the unconscious mind. For Jung, the self is an archetype of wholeness. It acts as a regulating center for the entire psyche. It is a power that transcends the ego. This self cannot be seen directly through simple observation. Instead, it is experienced through a process called individuation. This is a type of maturing where the whole person becomes cohesive.

Psychiatry examines what happens when the sense of self becomes disordered. Certain conditions can break the feeling of sameness. For example, depersonalization can make a person feel different from themselves. This sometimes occurs in schizophrenia or schizoaffective disorder. In these states, a person's internal experiences might feel like delusions. However, the person believes these events are part of their essential being. PET scans provide interesting scientific data on these experiences. They show that hallucinations are processed in the same brain areas as actual sounds. This can lead to long-lasting visions or auditory stimuli. Some people experiencing this might even believe they are in a state of rapture.

Neuroscience looks for the physical locations of the self in the brain. Researchers have identified specific regions used to retrieve self-knowledge. The medial prefrontal cortex and the medial posterior parietal cortex are two key areas. Other parts, like the anterior cingulate cortex, also help with self-reflection. The insular cortex is thought to be involved in self-reference. These brain structures work together to allow humans to think about themselves. By studying these neural processes, scientists hope to understand the complex, multiple selves of human identity. They want to find the biological grounding for our subjective experiences.

Sociology explores how culture shapes the construction of the self. Hazel Rose Markus and Shinobu Kitayama proposed a theory of two types of self. They suggested a continuum between the "independent" and "interdependent" self. An independent self is often seen as unique and eager for self-expression. An interdependent self focuses on being similar to others and maintaining group harmony. However, this theory has faced significant scientific criticism. A large 2016 study included 10,230 participants from 55 different cultural groups. This study failed to find a clear correlation between culture and these specific self-constructions. It showed that traits vary widely across all cultures.

Philosophy continues to ask deep questions about the nature of being. René Descartes was a prominent thinker regarding the self. Other philosophers, like Martin Buber, explored the distinction between "you" and "me." Some thinkers tackle the "vertiginous question" posed by Benj Hellie. This question asks why a specific subject is the one experiencing life right now. There are also many different theories regarding identity over time. "Open individualism" suggests there is only one subject who is everyone. This contrasts with "closed individualism," where identities are unique to each subject. Even thought experiments like the "teletransportation paradox" challenge our ideas. This paradox asks if a person recreated on another planet is truly the same self.
