The article discusses the Boltzmann brain paradox, which is the question of whether our lives and memories are real or just illusions. It explores Ludwig Boltzmann’s interpretation of entropy and his application of statistical reasoning to thermodynamics. The paradox arises in an infinitely old universe, where it is more likely for complex structures like brains to form randomly than for our current existence to be real. The resolution to the paradox lies in the Big Bang theory, but contemporary cosmologists still debate the likelihood of Boltzmann brains and their implications for the origin of the universe.
The article discusses the story of the Ring of Gyges from Plato’s “Republic” and the philosophical debate it sparks between Socrates and Glaucon. The story explores the concept of justice and the temptation of power, with Glaucon arguing that people would act unjustly if given the opportunity, while Socrates believes that true justice brings both intrinsic and extrinsic benefits. The Ring of Gyges serves as a symbol of the moral dilemma faced when given the chance to act without consequence.
The article discusses the psychology behind forbidden desires, focusing on reactance theory and the social network effect.

The article discusses the ethical dilemma of using animal testing to protect against the potential threat of smallpox. While it is unethical to expose humans to the virus, labs are using animals as research subjects, raising the question of whether it is right to harm animals to protect humanity. The article explores different philosophical perspectives on the value of life and moral status, highlighting the complexities and uncertainties involved in making moral decisions.
The article discusses a feud between two brothers in a German town that divided the entire community. The article then explores the minimal group paradigm, a psychological experiment that shows how even arbitrary group distinctions can lead to in-group bias and conflict. The findings suggest that people use group membership to form their sense of identity, which can lead to favoritism towards their own group. The article concludes by emphasizing the importance of inclusivity in order to overcome these biases.
Economist Kate Raworth challenges the conventional wisdom of economic growth as a sign of progress. She argues that our addiction to endless economic growth is leading to severe problems and proposes a new model called the Doughnut Model, which emphasizes the balance between meeting the essentials of life and ecological degradation.
Artificial intelligence (AI) is expected to bring significant changes to our lives and the world, but there is uncertainty about how these changes will manifest. Renowned AI expert Stuart Russell highlights the problem of fixed objectives in AI systems, which can lead to unforeseen and harmful consequences. He suggests building AI systems that are aware of their own uncertainty and emphasizes the need to avoid over-reliance on AI to prevent a loss of understanding and knowledge. The arrival of general-purpose AI is a gradual process, and while the timeline is uncertain, it is important to prepare for the profound changes it will bring.
The brain plays a crucial role in the experience of love, from the infatuation stage to the attachment stage. During infatuation, there is increased activation in the reward-processing and motivation hub of the brain, while during attachment, hormones like oxytocin and vasopressin promote feelings of trust and attachment. Heartbreak activates regions of the brain associated with pain and distress, but with time and support, individuals can heal and learn from the experience.
