A discussion on gun control, exploring philosophical, legal,
and ethical aspects of the issue. Eric Samson offers a range of arguments and
counterarguments on the necessity and consequences of gun laws. The
conversation includes the right to self-defence, the impact of gun ownership on
violence and society, victims of violent crimes, and proposals for mitigating
gun violence without infringing on gun rights. Special attention is given to

Ethical Quandaries of Autonomous Weapon Systems | Afonso Seixas-Nunes
We speak with Father Afonso about the use of weapon systems
in warfare. The discussion explores a thought experiment involving two states
at war and the deployment of autonomous drones capable of targeting terrorists without
human intervention. Key topics include the legality and morality of such
systems, the potential for reducing civilian casualties, the challenge of
machine errors leading to war crimes, and the shifting responsibility in
decision-making from humans to machines. The conversation also addresses the
technological advances in AI, the issues of accountability and transparency
with autonomous systems, and the philosophical implications of removing human
judgment from warfare. We examine potential future scenarios where autonomous
weapons could be misused by non-state actors or influenced by automation bias,
raising critical questions about the control, ethics, and implications of
advanced AI in military and civilian contexts.

Paediatric Gender Medicine | Moti Gorin and Holly Lawford-Smith
We begin by imagining a world where children are separated by sex at birth and raised without exposure to traditional gender norms. We debate whether gender incongruence is a result of nature or social conditioning. We discuss gender affirming care for children, highlighting the complexity of diagnosing gender dysphoria amidst co-occurring psychiatric conditions and the potential influence of social contagion. Key insights include questioning the lack of robust evidence for the efficacy of puberty blockers and cross-sex hormones, and the need for comprehensive psychosocial care before considering medical transition. The Cass Review was released after we recorded our conversation, but we address similar concerns.

Peter Singer on Animal Liberation Now
Peter Singer delves into difficult ethical
questions regarding animal rights, the morality of factory farming, and
difficult human-related ethical dilemmas.
Singer discusses his views as a
consequentialist, examining the impact of our choices on animal suffering, the
ethical considerations around organ donation from anencephalic children, and
the broader implications of such decisions.
What are the moral implications of eating
meat from factory farms versus ethically raised animals, and cannibalism under
hypothetical scenarios with no harm to others?
Singer emphasizes the need for considering
the consequences of our actions, shedding light on the pressing need to reform
our food production systems and make more ethical choices in our daily lives.

We Should Want Immortality | John Martin Fischer
John Martin Fischer argues that life
constantly offers new experiences and perspectives that prevent it from
becoming monotonous.
He delves into the idea of living a
significantly extended life without aging and the implications it has on
personal identity and society at large. Fischer distinguishes between true
immortality and radical life extension, favoring the latter for its exit
strategy options.
The conversation covers the value of life
experiences, the philosophical questions around personal identity over time,
and the ethical considerations of immortal life.
