Philosopher's Zone

Behind the familiar Buddhist doctrine that "there is no self" lies a centuries-long tradition of dispute and disagreement. Reductionists believe that the self is no more than a bundle of sense impressions and mental states that add up to nothing of substance or permanence, while emergentists believe that the self is something more - something related to these impressions and mental states, but not reducible to them. We're not going to settle the argument this week, but we will be exploring the ethical ramifications and asking what's at stake.

There are certain things about the world that we think we know for sure, and yet philosophical reason tells us cannot be true. Can you fly? are you real? is the world a hallucination? The answers seem self-evident, but this week we're exploring philosophical thought experiments that pull the rug out from under common sense and intuitive certainty.

Scottish philosopher Adam Smith (1723-1790) is often described as an arch capitalist, the "father of modern economics" - and at a glance it's easy to see why. His Inquiry Into the Nature and Causes of the Wealth of Nations provided the theoretical foundation for free market capitalism and the economic policies that prevailed throughout the Industrial Revolution. But to see Smith as an extreme free market ideologue is to get him badly wrong.

Artificial intelligence is beginning to revolutionise many aspects of human existence - but how does it rate on friendship? The question is less theoretical than it seems: media reports of people developing 'relationships' with chatbots are becoming more common, and while we may instinctively recoil from this prospect, it's not clear that AIs could never deliver at least some of the benefits of genuine friendship.

It's often claimed that the Enlightenment was a time when Europeans awoke from their superstitious slumber, discovered rationality, got started on science and threw religion in the bin. But a surprising number of Enlightenment philosophers had religious commitments — including Immanuel Kant, whose work at the time was understood as not just a religion, but a rival to Christianity.
