Study Notes on Personal Identity - Module Two, Unit Four

Module Two: Unit Four - Personal Identity

Introduction to Personal Identity

  • This unit marks the beginning of Module Two, which focuses on the theme of personal identity.

  • The course structure consists of four modules, each comprising three units.

Fundamental Vocabulary

  • Properties: Refers to the qualities, characteristics, or features of a thing.

    • Example: In the context of Barbie, many of her possessions are typically pink.

    • Pink is described as an accidental property, not an essential one.

Types of Properties

  • Accidental Properties:

    • Definition: Features that can change without altering the fundamental nature of a thing.

    • Example: Barbie can wear a purple dress instead of pink and still be recognizable as Barbie.

  • Essential Properties:

    • Definition: Characteristics that, if altered, change the fundamental nature of the thing.

    • Example: The thought experiment involving John Locke's concept of the mind and body.

Locke's Thought Experiment

  • Scenario: A prince's soul awakens in the body of a cobbler.

    • Cobblers are individuals who make shoes.

    • Key argument: The body is an accidental property, as it can change over time (e.g., aging, fitness).

    • The mind is considered essential due to psychological continuity:

    • Comprises memories, habits of thought, actions, and the narrative of the self that transcends physical changes.

  • Question of Identity:

    • If the prince’s mind inhabits the body of a cobbler, does the mind define the identity?

    • According to Locke, the person is the prince, not the cobbler, due to the essential nature of the mind.

Teleportation and Identity

  • Concept of Teleportation:

    • Description: A technology that disassembles the body into particles and reconstructs it elsewhere.

    • Example: Seen in science fiction, such as Star Trek.

  • Locke’s Perspective:

    • The body is necessary for continuous existence of the mind.

    • Issue: In teleportation, there is a brief suspension of identity (the body exists, then doesn't, and then exists again).

    • Raises questions about the continuity of consciousness.

  • Critical Inquiry:

    • If the mind is transported in a way that breaks continuity, is the consciousness the same?

    • What happens if duplicates are made from the mind? Which one is the original identity?

Derek Parfit's Perspective

  • Contrasting View: Parfit argues that there is no essential self.

    • Unlike Locke, he asserts that consciousness does not require continuity.

  • Analogy with Operating Systems:

    • When a computer is off, the operating system doesn't exist; it only comes to life with the hardware being operational.

    • Parfit suggests identity is fluid, changing over time.

Identity Over Time

  • Changing Identity:

    • Individuals are not the same from one day to another, nor over years.

    • Reflection on personal growth: Experiences and memories influence our current identity.

    • Parfit notes that memories are imperfect; they evolve as we remember and reinterpret them.

  • Fluid Sense of Self:

    • Parfit posits that we are collections of thoughts, feelings, and experiences, which shift and adapt rather than being static and essential.

    • Every aspect of identity can be considered an accidental property.

Thought Experiments by Parfit

  • Parfit presents numerous scenarios to challenge the notion of a consistent identity:

    • Questions such as: What if I removed parts of my brain? What if alternate versions of me existed?

    • Emphasizes that he cannot find any essential property that determines identity; everything is subject to change.

Critique and Broader Implications

  • Sociocultural Context:

    • Parfit's conclusions may reflect his personal background as a privileged philosopher.

    • The module will explore the broader social aspects of identity, their importance in public discourse, and the complexities in defining oneself.

Conclusion

  • The analysis of personal identity is complex and multifaceted, involving philosophical inquiry into what truly constitutes the self.

  • Upcoming discussions will delve into how social identities shape and influence personal identity.
