Have you ever wondered what makes you, well, you? The idea of personal identity is a fascinating topic that often pops up in science fiction. Take The Doctor from the famous series Doctor Who, for example. Each version of The Doctor has a different body, personality, and memories, yet they’re all considered the same character. This makes us think about our own identities and what truly defines us.
Previously, we talked about identity and how things can stay the same over time. It’s easy to see how objects like ships or trees can change yet remain the same. But when it comes to people, it’s more complicated. Most of us believe we’re the same person from birth to death, even though we change physically and mentally throughout our lives.
One popular idea about personal identity is the Body Theory. This theory suggests that we are the same person because we have the same body from birth to death. But here’s the catch: our bodies are always changing. We lose and grow new skin cells, our blood cells die and are replaced, and our bones are constantly being remodeled. So, how much can our bodies change before we’re considered a different person?
Philosopher Bernard Williams came up with a thought experiment to explore where we think our identity lies. Imagine a mad scientist kidnaps you and plans to swap your mind with someone else’s. After the swap, you have to decide which body gets a reward and which one gets punished. Your choice might reveal what you believe is the core of your identity.
John Locke had a different idea called the Memory Theory. He believed that our identity is based on our consciousness, not our physical body. According to Locke, if you can remember past experiences, you’re connected to those past versions of yourself. But this theory has its flaws. For example, we don’t remember being born, and if someone loses their memories due to dementia, are they still the same person?
While the Memory Theory is intriguing, it has its challenges. Memories can be distorted or even made up, which raises questions about how these inaccuracies affect our identity. If our memories aren’t completely reliable, can we still say we’re the same person based on them?
Understanding personal identity isn’t just a philosophical question; it matters in real life. Our sense of identity affects our responsibilities to others and how we view promises and commitments. For instance, if you and your boss aren’t the same people next week as you are today, does that change the promises you make now? Our lives and society are built on the idea that people stay consistent over time.
To sum up, we’ve looked at two main theories of personal identity: the Body Theory and the Memory Theory. Both have their challenges and raise important questions about what it means to be the same person over time. As we continue to explore identity, we need to think about its impact on our lives and relationships. In our next discussion, we’ll dive deeper into whether the idea of a constant “self” is necessary for understanding identity.
Engage in a classroom debate on the Body Theory vs. the Memory Theory. Split into two groups, each defending one theory. Use examples from the article and your own experiences to support your arguments. Consider how each theory addresses changes over time and what truly defines personal identity.
Participate in a role-play based on Bernard Williams’ thought experiment. Imagine you are the person whose mind is swapped. Discuss with your peers which body you would choose for the reward and which for the punishment. Reflect on what this reveals about your beliefs regarding identity.
Keep a memory journal for a week. Record daily experiences and reflect on how these memories contribute to your sense of identity. At the end of the week, review your entries and discuss with a partner how reliable these memories are and how they shape who you are.
Create a timeline of your life, highlighting significant physical and mental changes. Include events that have shaped your identity. Share your timeline with the class and discuss how these changes align with the Body Theory and Memory Theory.
Write a short essay on the importance of personal identity in real-life scenarios. Consider how identity affects responsibilities, promises, and commitments. Use examples from the article and your own life to illustrate your points.
