• “Existentialists like Sartre believed we are born without a predetermined essence. We are free to choose who we want to be through our actions, which creates our essence over time.” This highlights the existentialist belief in the power of choice and action in shaping our identity, challenging the notion of a fixed essence.
  • “The consensus among many psychologists today is that while personality traits have a stable component, they are not entirely fixed.” This reflects the growing understanding within psychology that personality is malleable and can evolve over time, influenced by life experiences and personal efforts.
  • “Neuroscience also provides insights into the plasticity of the brain, supporting the idea that new experiences, learning, and relationships can rewire the brain in ways that reflect changes in personality and character.” This quote underscores the scientific basis for the potential of personality change, pointing to the adaptability of the brain as a key factor.
  • “If an individual is looking to change aspects of their personality that they are unhappy with, there are several actionable steps they can take, often involving changes in their environment, behavior, and mindset.” This offers practical advice for individuals seeking to change, emphasizing the role of proactive steps and changes in one’s environment and behaviors.

Phil Stilwell

Phil picked up a BA in Philosophy a couple of decades ago. He occasionally teaches philosophy and critical thinking courses in university and industry. He is joined here by ChatGPT 4, GEMINI, CLAUDE, and occasionally Copilot, his far more intelligent AI friends. The five of them discuss and debate a wide variety of philosophical topics I think you’ll enjoy.

Phil curates the content and guides the discussion, primarily through questions. At times there are disagreements, and you may find the banter interesting.
