Join neuroscientist, philosopher, and best-selling author Sam Harris as he explores important and controversial questions about the human mind, society, and current events. The Making Sense podcast was selected by Apple as one of iTunes Best of 2015.

In this episode, we try to trace morality to its elusive foundations. Throughout the compilation we take a look at Sam’s “Moral Landscape” and his effort to defend an objective path towards moral evaluation.

We begin with the moral philosopher Peter Singer who outlines his famous “shallow pond” analogy and the framework of utilitarianism. We then hear from the moral psychologist Paul Bloom who makes the case against empathy and points out how it is more often a “bug” in our moral software than a “feature.” Later, William MacAskill describes the way a utilitarian philosophy informs his engagement with the Effective Altruism movement.

The moral psychologist Jonathan Haidt then puts pressure on Sam’s emphasis on rationality and objective pathways towards morality by injecting a healthy dose of psychological skepticism into the conversation.

After, we hear a fascinating exchange with the historian Dan Carlin where he and Sam tangle on the fraught issues of cultural relativism.

We end by exploring the intersection of technological innovation and moral progress with the entrepreneur Uma Valeti, whom Sam seeks out when he encounters his own collision with a personal moral failure.
