General (ret.) H.R. McMaster, the Fouad and Michelle Ajami Senior Fellow at the Hoover Institution, returns to Uncommon Knowledge to discuss his latest book, At War with Ourselves, in which he candidly recounts his experiences as former national security advisor to President Donald Trump from 2017 to 2018.

In this wide-ranging interview, McMaster delves into the complexities and challenges he faced while serving in the administration and describes his role in providing the president with multiple options and safeguarding his independence of judgment, partially by drawing on the Stoic philosophy of Epictetus to “play well the role assigned to you.” He reflects on the internal tensions and conflicts within the White House, often exacerbated by differing agendas among staff and cabinet members. McMaster also discusses the difficulties in maintaining a productive relationship with President Trump, especially when offering candid advice that sometimes led to alienation. The conversation is a revealing look into McMaster's often tumultuous experiences in the Trump White House but also emphasizes the importance of a well-structured decision-making process in the realm of national security.

“Are we alone in the universe?” That’s the central question we put to astrophysicist Dr. Luke Barnes, cosmologist Dr. Brian Keating, and philosopher Dr. Jay Richards.

Our guests delve into the probabilities and challenges of finding extraterrestrial life, considering the vastness of the cosmos and the fine-tuning necessary for life to exist. They explore the implications of the SETI project, the rarity of Earth-like conditions, and the potential for habitable planets in other solar systems. This discussion is set against the backdrop of broader scientific and philosophical inquiries, including the Big Bang, the multiverse theory, and the role of humanity in the cosmic order. The conversation offers a deep and nuanced perspective on the search for life beyond Earth and what it could mean for our understanding of the universe and our place within it.

Stephen Meyer is the author of Return of the God Hypothesis and the director of the Discovery Institute. James Tour is a synthetic organic chemist and professor at Rice University, renowned for his work in nanotechnology and his skepticism toward the current scientific models explaining the origin of life.

In this wide-ranging conversation, Meyer and Tour contrast biological evolution with the more complex challenge of chemical evolution, where modern science still struggles to explain how nonliving chemicals could give rise to life. They critique early experiments like the Miller-Urey experiment, emphasizing that producing basic molecules is far from creating life itself. Meyer and Tour also argue that as scientific understanding deepens, the complexity of life's origins becomes more daunting, raising both scientific and philosophical questions about the adequacy of the current mainstream scientific explanations and theories for the origin of life.
